182. “We want to promote people-to-people exchanges so that China and the United States can really join together, not just to solve the problems of China or the United States, but some of the big problems facing the entire world. From climate change to famine to even terrorism.”

183. “All cities do face similar, significant trends in the future… most importantly global warming and climate change.”

184. “Being told about the effects of climate change is an appeal to our reason and to our desire to bring about change. But to see that Africans are the hardest hit by climate change, even though they generate almost no greenhouse gas, is a glaring injustice, which also triggers anger and outrage over those who seek to ignore it.”

185. “Global climate change has a profound impact on the survival and development of mankind. It is a major challenge facing all countries.”

186. “Developed countries should support developing countries in tackling climate change. This not only is their responsibility, but also serves their long-term interests.”

187. “China has adopted and is implementing its national climate change program. This includes mandatory national targets for reducing energy intensity and discharge of major pollutants and increasing forest coverage and the share of renewable energy for the period of 2005 through 2010.”

188. “I believe we should reframe our response to climate change as an imperative for growth rather than merely being a way of being green or meeting environmental commitments.”

189. “As far as I'm aware, everybody in the shadow cabinet accepts that there's a compelling case on climate change and a strong scientific case.”

190. “Homes and buildings, many of which are old and drafty, eat up 40 percent of the energy America uses. Such inefficiencies perpetuate our reliance on foreign oil, imperiling our national security and increasing our contribution to climate change.”

191. “Climate change is a controversial subject, right? People will debate whether there is climate change… that's a whole political debate that I don't want to get into. I want to talk about the frequency of extreme weather situations, which is not political.”

192. “Climate change is having a dramatic effect on the ground.”

193. “The area of climate change has a dramatic impact on national security.”

194. “We have no reason to think that climate change is harmful if you look at the world as a whole. Most places, in fact, are better off being warmer than being colder. And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods.”

195. “If we do not change our negative habits toward climate change, we can count on worldwide disruptions in food production, resulting in mass migration, refugee crises and increased conflict over scarce natural resources like water and farm land. This is a recipe for major security problems.”

196. “Investing now in safe-guarding people by helping them to adapt to climate change, will help save money and lives while building resilience.”

197. “The best way to tell people about climate change is through non-fiction. There's a vast literature of outstanding writing on the subject.”

198. “Climate change is very real.”

199. “Some argue that now isn't the time to push the green agenda - that all efforts should be on preventing a serious recession. That is a false choice. It fails to recognise that climate change and our carbon reliance is part of problem - high fuel prices and food shortages due to poor crop yields compound today's financial difficulties.”

200. “Foreign policy is inseparable from domestic policy now. Is terrorism foreign policy or domestic policy? It's both. It's the same with crime, with the economy, climate change.”

201. “The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East, but they need a coalition of Christian and Jew and Muslim.”

202. “We are already experiencing the symptoms of climate change, especially with a hotter and drier climate in southern Australia - the rush to construct desalination plants is an expensive testament to that.”

203. “If Margaret Thatcher took climate change seriously and believed that we should take action to reduce global greenhouse emissions, then taking action and supporting and accepting the science can hardly be the mark of incipient Bolshevism.”

204. “But Australia faces additional regional and global challenges also crucial to our nation's future - climate change, questions of energy and food security, the rise of China and the rise of India. And we need a strong system of global and regional relationships and institutions to underpin stability.”

205. “Climate change was a point of division between Obama and Republican rival Mitt Romney. The president declared climate change a global threat, acknowledged that the actions of humanity were deepening the crisis, and pledged to do something about it if elected.”

206. “The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change.”

207. “If we invest in researching and developing energy technology, we'll do some real good in the long run, rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century, and for many other global problems we have low-cost, durable solutions.”

208. “The saddest fact of climate change - and the chief reason we should be concerned about finding a proper response - is that the countries it will hit hardest are already among the poorest and most long-suffering.”

209. “I want to use my position of leadership to help move along at a faster pace what I believe and know the Obama administration wants to do around the urgency of climate change.”

210. “If we are ever to halt climate change and conserve land, water and other resources, not to mention reduce animal suffering, we must celebrate Earth Day every day - at every meal.”

211. “What do we do about climate change bearing down upon us?”

212. “I hope that in future Congresses there will reemerge a recognition that climate change is a reality, that our policies to meet our energy needs must also deal responsibly with environmental issues, including the damage caused by greenhouse gas emissions.”

213. “I sort of feel that climate change will be solved by science. I just feel instinctively that we will find a way of saving ourselves. But I am less confident that we won't destroy ourselves in other ways.”

214. “I believe climate change is real - and I believe we have to act to protect the climate as fast as we possibly can.”

215. “I would point out that if you're a believer in the Bible, one would have to say the Great Flood is an example of climate change and that certainly wasn't because mankind had overdeveloped hydrocarbon energy.”

216. “So when you're dealing with an existential threat like death or like climate change, if you see it as 'we are all toast anyway,' then denial is a pretty good way of coping.”

217. “Among all the tests President Obama faced in his first term, his biggest failure was climate change.”

218. “Geoengineering - the deliberate, large-scale manipulation of the earth's climate to offset global warming - is a nightmare fix for climate change.”

219. “If you are interested enough in the climate crisis to read this post, you probably know that 2 degrees Centigrade of warming (or 3.6 degrees Fahrenheit) is the widely acknowledged threshold for "dangerous" climate change.”

220. “Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney.”

221. “Ever since the collapse of cap and trade legislation and the realization that President Obama is unlikely to ever utter the words 'climate change' in public again, much less use the bully pulpit to prepare the nation for the catastrophic risks of inaction, the movement has been in a funk.”

222. “Maybe more climate activists will think about the climate change not as an international problem to be resolved in an air-conditioned meeting hall, but as a guerilla war to be fought in the streets.”

223. “Bill Gates is a relative newcomer to the fight against global warming, but he's already shifting the debate over climate change.”

224. “I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.”

225. “Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.”

226. “After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with climate change. So, I decided to give one talk, and then it snowballed into another talk and eventually to even protesting and getting arrested.”

227. “Being at NASA and having the access to both computing capability and satellite observation capability is kind of the ideal research situation to try to understand global climate change.”

228. “We are sliding back into a dark era, and there seems little we can do about it. I am profoundly depressed at just how difficult it has become merely to get a realistic conversation started on issues such as climate change or genetically modified organisms.”

229. “We need healthy forests if we want to protect our climate. As the climate changes, forests become more vulnerable to insect outbreaks, droughts and wildfires. Simultaneously, when our forests are destroyed, their carbon is released back into the atmosphere, further impacting climate change. It's a horrifying one-two punch.”

230. “Look, I'm a huge supporter of Obama's - he's the first president I ever donated money to. But I think in terms of climate change and the environment, he's been, at best, disappointing.”

231. “The trouble with climate change is it's an extraordinarily diverse and complex issue, but for example if the BBC would let me make some of the programmes I'd like to make on climate change, I bet you there would be a change of emphasis.”

232. “Climate change and dependence on foreign oil are problems that won't go away on their own. Tabling plans to deal with them doesn't make it easier for companies to plan and invest; it makes it harder.”

233. “We will not overcome world poverty unless we manage climate change successfully. I've spent my life as a development economist, and it's crystal clear that we succeed or fail on winning the battle against world poverty and managing climate change together. If we fail on one, we fail on the other.”

234. “If you look at all the serious scientists in the world, there is no big disagreement on the basics of this… it would be absolute lunacy to act as if climate change is not occurring.”

235. “We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They're also being diversionary because if we don't act the risks are enormous.”

236. “Those who say that climate change doesn't exist are being understood as the flat-earthers that they are, as the people who deny the link between smoking and cancer, as the people who denied the link between HIV and AIDS.”

237. “How is it that, in the face of overwhelming scientific evidence, there are still some who would deny the dangers of climate change? Not surprisingly, the loudest voices are not scientific, and it is remarkable how many economists, lawyers, journalists and politicians set themselves up as experts on the science.”

238. “The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.”

239. “I think that once people understand the great risks that climate change poses, they will naturally want to choose products and services that cause little or no emissions of greenhouse gases, which means 'low-carbon consumption.' This will apply across the board, including electricity, heating, transport and food.”

240. “A diet that relies heavily on meat production results in higher emissions than a typical vegetarian diet. Different individuals will make different choices. However, the debate about climate change should not be dumbed down to a single slogan, such as 'give up meat to save the planet.'”

241. “My father's generation's crisis was fighting fascism. Ours is fighting climate change. It is much harder because you can't see it, it is not an obvious threat. But the solution is in our hands.”

242. “I don't believe that the science is settled on man-made climate change. And so - while I live in Colorado - you see where I live. I love the environment. And - and I want to make sure we do everything we can to protect the environment. I don't want government to put artificial standards on us.”

243. “One volcano puts out more toxic gases - one volcano - than man makes in a whole year. And when you look at this 'climate change,' and when you look at the regular climate change that we all have in the world, we have warm and we have cooling spells.”

244. “Climate change is obviously happening and there is obviously a man-made contribution.”

245. “I'm not against entertainment: if someone wants to read nonsense-mongers, let them, but I resent the appearance of parity between two articles on an issue as serious as climate change when one article is actually gibberish masked in pseudoscience and the other is well informed and accurate.”

246. “I don't believe - till something radical changes that we are not on track to do - that hybrids are material to climate change. They're fashionable, everybody loves them, the Prius is selling well, but so are Gucci bags. But they don't impact the way the world carries stuff. You know it's a fashion statement.”

247. “The U.S. has fallen well behind Europe in recognizing climate change and the implications of climate change.”

248. “I'm a fiscal hawk. I vote against all taxes, but I do believe the environment, and climate change, is a bigger issue than fiscal deficits are as a risk to the nation.”

249. “As is widely accepted, putting a price on carbon pollution is the lowest cost and most efficient way to tackle dangerous climate change.”

250. “I want to ensure and the Government wants to ensure that Australia is well prepared to tackle dangerous climate change with a scheme which is both responsible and which meets our international commitments.”

251. “With so much evidence of depleting natural resources, toxic waste, climate change, irreparable harm to our food chain and rapidly increasing instances of natural disasters, why do we keep perpetuating the problem? Why do we continue marching at the same alarming beat?”

252. “Climate change could produce a lot of misery and waste without necessarily leading to large-scale armed conflict, which depends more on ideology and bad governance than on resource scarcity.”

253. “We need policy change, and the most important thing people can do is to contribute and participate in the political process. We have to vote climate change deniers and people who will create subsidies for the fossil fuel industry out of office. We have to protest when bad decisions are being made about fracking or tar sands.”

254. “What we've got is the wholesale embrace of fracking domestically, internationally and for export. And this couldn't be further from what we really need to do to address climate change.”

255. “In the years to come, the combination of climate change and population growth could have a devastating effect on the planet and, needless to say, on humanity.”

256. “Libertarians believe that any government interference is bad. Anyone with a brain knows that climate change needs governmental leadership, and they can smell this is bad news for their philosophy. Their ideology is so strongly held that, remarkably, it's overcoming the facts.”

257. “At the Global Crop Diversity Trust, we work to conserve the diversity that will allow the adaptation and evolution of our agricultural crops in the context of climate change and other challenges.”

258. “The U.S. has historically been the world's largest contributor to climate change.”

259. “Public discourse about climate change has resulted in the erroneous idea that it's all about cost, burden and sacrifice. If the math was correct, everyone would see it's about profit, jobs and competitive advantage.”

260. “The Ocean Health Index is like the thermometer of the ocean. It will allow us to take the temperature to know what is going on at the global level, trying to integrate different impacts, including overfishing, invasive species, coastal development, and climate change.”

261. “I think governments will increasingly be tempted to rely on Silicon Valley to solve problems like obesity or climate change because Silicon Valley runs the information infrastructure through which we consume information.”

262. “It is fairly well-known what has been behind that climate change denial in America: vast sums pumped into an ignorance industry by the oil and gas lobbies.”

263. “On the environment and climate change, I suspect that future generations will think there was too much timidity, too much fear of upsetting business. Basically, New Labour was very nervous about regulating business, or requiring it to do anything, even when there was a very clear social or environmental case for doing so.”

264. “The biggest barrier to dealing with climate change is us: our own attachment to habits that are hard to shift, and our great ability to park or ignore uncomfortable choices.”

265. “If we brought the mammoth back to Siberia, maybe that would be good for the ecosystems that are changing because of climate change.”

266. “Climate change should not fundamentally be seen as a political or partisan issue, but it has been turned into a political football primarily by the climate deniers who have a vested interested in maintaining the status quo. That includes certain industrial interests, financial interests and political interests.”

267. “The problem with climate change is that it's quite complicated for the ordinary person to understand.”

268. “A 501(c)3 can't lobby. A 501(c)3 can't invest in a company or build an industry. It may be that the only way to deal with climate change is to create an industry or build companies.”

269. “Many of the issues we face in dealing with rapid climate change are well suited to an engineering mind.”

270. “In the case of climate change, the threat is long-term and diffuse and requires broad international action for the benefit of people decades in the future. And in politics, the urgent always trumps the important, and that is what makes it a very difficult and challenging issue.”

271. “I think Bloomberg's broad vision of the environment in New York City is something I agree with. I broadly stand with his vision for how to deal with climate change and prepare for future weather events.”

272. “Veganism is an answer for almost every problem facing the world in terms of hunger and climate change.”

273. “Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.”

274. “For all of the hurtling towards climate change, there's also a lot more understanding of it than there was when we were kids. They don't call environmentalists tree huggers any more, so there's hope!”

275. “We need to start by having a conversation about climate change. It would be irresponsible to avoid the issue just because it's uncomfortable to talk about.”

276. “I talk to fashion designers and say I want some money to save the rainforest, and they say, 'Oh, I agree with you completely Vivienne. Yes, climate change, it's definitely happening,' but they don't feel that they can do anything about it; they don't even think 'Well let's stop it!'”

277. “The main message we want to get out there is that climate change is caused by the rotten economic system.”

278. “I don't know much about climate change. But I'm pretty sure we better figure out what to do to lessen its impact - at least its health impact - and that's not going to happen unless you have a lot of young talent interested in these topics.”

279. “Make no mistake: Tackling climate change is vital. But to see everything through the lens of short-term CO2 reductions, letting our obsession with carbon blind us to the bigger picture, is to court catastrophe.”

280. “Climate change is not a discrete issue; it's a symptom of larger problems. Fundamentally, our society as currently designed has no future. We're chewing up the planet so fast, in so many different ways, that we could solve the climate problem tomorrow and still find that environmental collapse is imminent.”

281. “There's no really rosy scenario ahead, where climate change just doesn't happen, but I believe we don't have the ethical right to throw our hands up in the air and say, 'Game over.' Whatever pathway we choose, our descendants will be dealing with that reality for centuries to come.”

282. “People in all walks of life, and especially business, do not want to experience the collapse of cities like New York along with global finance and economy in chaos, but this is what business faces if we continue to attribute climate change to fossil fuels alone.”

283. “Exxon, one of the companies that has spent tens of millions of dollars denying climate change, denying any responsibility to deal with, taking government subsidies on a massive scale, now their ads are all about, 'Oh, we want a clean future. We're looking at clean energy and all that stuff.'”

284. “Going meatless reduces our carbon footprint and helps us lead the way towards climate change.”

285. “How we grow food has enormous effects on the environment - climate change as well as pollution of air, water, and soil.”

286. “Society has to get a grip and put a tax on carbon. Of course, there is much that flows from that, and it is a complex situation. The small details of something such as climate change are political and social, and they are a lot about fairness and how we rebalance towards a fairer society.”

287. “Climate change is the 800-pound gorilla in the living room that the media dances around. But in the scientific community, it's a settled question: 95 percent of scientists believe this is happening with 100 percent confidence temperatures are rising.”

288. “Climate change - for so long an abstract concern for an academic few - is no longer so abstract. Even the Bush administration's Climate Change Science Programme reports 'clear evidence of human influences on the climate system.'”

289. “The Conservatives are a confusing lot. They first denied climate change was a serious issue and then suggested strengthening the nuclear industry as a solution to it. They oppose the European Union, but support joining North American Free Trade Agreement, despite its obvious failure.”

290. “We have little choice but to place a certain level of trust in scientists - even when it comes to the model-driven speculative discipline of climate change. And, need it be said, most scientists take great care in being honest, principled and precise.”

291. “I had hoped all of Congress would recognize that it is imperative for our health, economy, and national security that we address the effects of climate change before they get even worse.”

292. “In Congress, I am focused on the effects of climate change, including ocean acidification and sea-level rise - both of which are threats to healthy oceans that sustain life on- and off-shore.”

293. “Clean air and a healthy climate benefit all of us, but it will take a diverse coalition to step up to the threat posed by unchecked climate change.”

294. “It's the poorer people in tropical zones who will get really hit by climate change - as well as some ecosystems, which nobody wants to see disappear.”

295. “Human-caused climate change threatens almost every aspect of human existence.”

296. “Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.”

297. “Without industry, finance and government consciously and collaboratively ensuring that capital flows to where it is needed in order to ensure the scaling up of climate change solutions, whatever deal is agreed risks never being realised.”

298. “In reality, climate change is actually the biggest thing that's going on every single day.”

299. “We have to overthrow the idea that it's a diversion from 'real' work when scientists conduct high-quality research in the open. Publicly funded science should be open science. Improving the way that science is done means speeding us along in curing cancer, solving the problem of climate change and launching humanity permanently into space.”

300. “Some people will deny anything that displeases or scares them: unusual pain in their chests, unwanted lumps beneath their skin, or the fact that humans share ancestry with apes are a few examples. Another is climate change.”

301. “The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.”

302. “Most reputable scientists agree that climate change is real and that the effects are likely to be bad. But nobody can say for sure exactly what 'bad' means. The safest and most equitable way out of this horrific mess is simple: cut fossil-fuel emissions.”

303. “Deliberately modifying the earth's atmosphere would be a desperate gamble with significant risks. Yet the more likely climate change is to cause devastation, the more attractive even the most perilous attempts to mitigate those changes will become.”

304. “Today's voguish threats, including climate change, population growth, massive war, and resource depletion, are all amenable to a fix if we act prudently. And even if we don't, these problems are incapable of obliterating all of humanity, let alone destroying the Earth. No, the real End of Days will happen slowly, as the Sun ages.”

305. “After the ignominious collapse of the Copenhagen global climate change summit in 2009, Bolivia organised a People's Summit with 35,000 participants from 140 countries - not just representatives of governments, but also civil society and activists.”

306. “I chose to document the lives of people living in a remote village in Alaska called Shishmaref because there we can literally see how climate change is affecting their homes, livelihoods and ultimately their lives.”

307. “Issues of energy, climate change, nuclear arms control and non-proliferation are all big deals. These are problems that we have to get right globally, not just nationally, and there are big benefits in cooperating, in terms of sharing costs, in terms of sharing risks, in terms of propagating the best answers.”

308. “Any objective look at what science has to say about climate change ought to be sufficient to persuade reasonable people that the climate is changing and that humans are responsible for a substantial part of that - and that these changes are doing harm and will continue to do more harm unless we start to reduce our emissions.”

309. “My understanding is that Exxon, in particular, did fund a variety of small think tanks to generate what amounts to propaganda against understanding of what climate change was doing, the human role in causing it.”

310. “Meat production is one of the leading causes of climate change because of the destruction of the rainforest for grazing lands, the massive amounts of methane produced by farm animals and the huge amounts of water, grain and other resources required to feed animals.”

311. “Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An 'ecological shock' could irreversibly degrade our environment.”

312. “The scientific community should work as hard as possible to address major issues that affect our everyday lives such as climate change, infectious diseases and counterterrorism; in particular, 'clean energy' research deserves far higher priority. And science and technology are the prime routes to tackling these issues.”

313. “Around the world, climate change is an existential threat - but if we harness the opportunities inherent in addressing climate change, we can reap enormous economic benefits.”

314. “I have been very encouraged by President Obama's call to action on climate change both at his Inauguration and in the State of the Union Address. This is a global imperative. I also welcome President Obama's intention to pursue reductions in nuclear arsenals.”

315. “Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.”

316. “Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.”

317. “We will never end poverty if we don't tackle climate change.”

318. “We are launching a campaign called Wind, Not War, which is about the alternatives to a fossil-fuels-based economy and looking at wind, an alternative energy, as key to that in terms of issues of global climate change as well as issues of democracy.”

319. “We must start to treat climate change as what it is - a threat to United States security. And we must not delay.”

320. “I'm not as convinced as a lot of people are that man-made climate change is the threat they think it is.”

321. “Many climate change deniers would have you believe that addressing climate change is all pain and no gain. This is simply not true. We can tackle this challenge while improving our personal health and the health of our economy. These are not competing interests; they go hand in hand.”

322. “Hollywood is the perfect conduit for the urgent message about climate change. We raise awareness all the time. We routinely take a film that nobody knows about and get 80 percent of the public to know about it in just 30 days. That's called marketing. We need to harvest Hollywood for climate change awareness.”

323. “For reasons we don't have to get into, climate change has become an incredibly polarized issue in the United States. I think that is sad. My own personal view is that we're in a planetary emergency such has not been seen in 600,000 years.”

324. “In my personal belief, the big problem with climate change is getting people to understand the magnitude and scale that we're dealing with. If you buy a vehicle that gets 35 miles to the gallon, that means nothing; it's not enough. We need to make changes across society and in every piece of the energy pie.”

325. “Even those who don't believe in climate change believe we should develop renewable energy. Americans get it: it's time. This is not controversial. It's actually right in the wheelhouse of American business.”

326. “It really gets on my goat that people keep quoting Dorothea Mackellar's 'My Country' as proof that there is no such thing as climate change. A poem written more than 100 years ago by a homesick 19 year old versus an ever-increasing body of refereed scientific thought… hmm, hard to know which way to jump, really.”

327. “The doomsayers of the 1970s were wrong about how quickly the world would run out of oil, but not about the dangers that hydrocarbon consumption posed to the global environment, especially with respect to climate change.”

328. “In the history of the world, all five mass extinctions have been accompanied by massive climate change, so we are facing an incredibly serious threat. In fact, we are technically in the sixth mass extinction right now, and it is the first mass extinction being attributed to humans.”

329. “There's no question that, um, you know, the oceans have risen, right? And the climate change part is, is a real part of it.”

330. “Climate change might be disastrous, but does that mean we want carbon taxes that raise the price of a gallon of heating oil to $10? And how exactly will those taxes affect economic growth?”

331. “Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture.”

332. “I think there's plenty of evidence that we need to stop spewing so much carbon into the air, that we're contributing to climate change and that we ought to look for alternatives.”

333. “Look at climate change; don't put your head in the sand. Understand that it is going to have profound effects on our resources and so much else.”

334. “You always have to be worried about something that is considered a so-called 'scientific theory' that fits every scenario. Climate change, as they've defined it, can never be disproved.”

335. “Ours is a world which feels so unsettled and dangerous in large ways, whether it's terrorism or global financial meltdown or climate change - huge things that affect us deeply, and yet things about which we can do, individually, very little.”

336. “Climate change is real.”

337. “I care about climate change because of our children. I want to safeguard their future.”

338. “I hear so many people talking about what's wrong, whether it's climate change or whatever, but so few say, 'Well, look, we've got this problem, so let's find the solution. Let's find a scientist, let's find politicians who are prepared to shape the future, or try and keep up with it.'”

339. “I do believe in the Bible as the final word of God. And I do believe that God said the Earth would not be destroyed by a flood. Now, do I believe in climate change? In my trip to Greenland, the answer is yes. The climate is changing.”

340. “Black Saturday reminded many Australians of what they know only too well: that of all the advanced economies, Australia is perhaps the one most vulnerable to climate change.”

341. “A Labor prime minister, Julia Gillard, who does believe in climate change, nevertheless advised her predecessor, Kevin Rudd, to abandon his emissions trading scheme.”

342. “We have to wrap this imperative of addressing climate change in a prosperity framework, and secondly we have to do a much better job of putting forward an American jobs agenda that's a match for the climate challenge.”

343. “Climate change is transforming the world in profound ways that continue to evolve.”

344. “Maryland is among the nation's most vulnerable states to the effects of sea level rise from climate change, and we are taking strong action to reduce carbon pollution.”

345. “Solar power is going to be absolutely essential to meeting growing energy demands while staving off climate change.”

346. “On almost every environmental issue I care about, in fact, I've been wrong at one point or another. I used to think that climate change was no big deal, that most environmental problems were massive exaggerations, that oil reserves were effectively unlimited, and more.”

347. “It is our duty as states, citizens, and industry leaders to make the energy transition a reality with the ultimate aim of reconciling two major priorities: to meet ever-increasing demand and to confront the complex issue of climate change.”

348. “I'm at one with Ed Miliband in saying that it's important that people have the right to express their democratic voices and also their deep concerns about climate change because we have a planet in peril.”

349. “As Development Secretary, I have seen in the developing world that climate change there is not a theory, is not a future threat: it is a contemporary crisis.”

350. “We don't think much about climate change and rising sea levels here in the U.S. Beyond a few gardeners, birders and hikers who notice the changes in our own ecosystem, we live on, blissfully unaware of our changing Earth. Our storms - Katrina, Sandy - are dismissed as once-in-a-century events.”

351. “Ah, to be a conservative climate change denier. While real scientists must do all the research and engage in heated debates about just how bad things are going to be, the deniers can rest easy in the bliss of willful ignorance.”

352. “We collaborate with other countries on issues like public health and climate change because we understand these issues affect our collective welfare.”

353. “I have friends who are science journalists, and I'm seeing stories of theirs or talking with them about ideas that they're pitching. Certain kinds of science are around me all the time, like climate change and biology.”

354. “Even the president's own Science and Technology Office head Mister Holdren says no one single weather event is due specifically to climate change.”

355. “At the simplest level, economics can better show us the consequences of our actions. Less simple are cases in which we don't have the knowledge to predict the full consequences. Global warming and climate change are examples.”

356. “Global climate change has become entangled with the problem of invasive species. A warmer climate could allow some invaders to spread farther, while causing native organisms to go extinct in their traditional habitats and making room for invaders.”

357. “Climate change is hugely exacerbated by changing patterns of how we choose to live, often in danger zones such as extremely vulnerable coastal zones - from New Jersey to the Philippines. This enormously increases the economic and human costs of hurricanes, rising seas and changing weather patterns.”

358. “The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.”

359. “Evolution, climate change, and the construction of the physical universe down to its atoms are processes that we measure in millions or billions of years.”

360. “The world that you and I live in is increasingly challenged. Population growth, pollution, over-consumption, unsustainable patterns, social conflict, climate change, loss of nature… these are not good stories.”

361. “We have serious challenges regarding climate change, unsustainable use of natural resources, water scarcity, loss of biodiversity, forests and farmland. Not to mention the huge inequality still prevailing in several parts of the planet.”

362. “We are working with the communities in building institutional relationships with local governments and businesses to create ways to get value from the Amazonian area in order to keep the forest as the forest. This makes sense for us from the perspective of climate change and of poverty.”

363. “I have often spoken about the importance of intentionality in philanthropy: that it has to stir the soul. This is true whether you are feeding the homeless, mentoring a child or working on climate change.”

364. “Truly, we do live on a 'water planet.' For us, water is that critical issue that we need. It's the most precious substance on the planet, and it links us to pretty much every environmental issue, including climate change, that we're facing.”

365. “When you talk to a Republican, many of them just outright say, 'Yeah. Climate change isn't real,' without assessing the facts, and it's a big problem. It's not a red or blue issue, it's a green issue… Not because of facts or science but because of emotion.”

366. “You will not solve global climate change by hitting the delete button.”

367. “First, how do we give everyone a fair shot at opportunity and security in this new economy? Second, how do we make technology work for us, and not against us - especially when it comes to solving urgent challenges like climate change? Third, how do we keep America safe and lead the world without becoming its policeman?”

368. “In China we need to do our own part to try to combat global climate change.”

369. “One thing most people would agree is that climate change would add further uncertainties to our already quite tight water supply situation in China.”

370. “I hope to see an integrated solution created to deal with both the local pollution problem and the global climate change problem.”

371. “Though every nation must do its part to address climate change, developed nations are responsible for the lion's share of carbon pollution in the atmosphere, and they have an obligation to help developing nations transition to a sustainable future.”

372. “Too often, the air conditioners we use to cool down also contribute to climate change - the very force that's fueling extreme heat.”

373. “I have been fighting climate change for two decades, and people often ask me how I remain hopeful in the face of extreme weather and grim forecasts. The answer is simple: I see countless solutions spreading across the nation and across the world. But we need more investment.”

374. “When climate change supercharges weather patterns, the disadvantaged often suffer first and most.”

375. “Climate change deniers would have us believe that oil, gas, and coal are the only ways to power a modern, industrialized society. They are wrong, and the proof is all around us.”

376. “Strong limits on carbon pollution will save Americans money, create jobs, improve our health, and help defuse climate change.”

377. “The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme.”

378. “Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil.”

379. “The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.”

380. “Climate change is the central environmental ill of our time. We have an obligation to protect our children from the dangers of this widening scourge, and we aren't yet doing enough about it.”

381. “The single most important thing we can do to protect our communities from climate change is to reduce dangerous carbon pollution.”

382. “Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.”

383. “We can choose food that doesn't lead to illnesses like diabetes and cancer. We can choose food that doesn't contribute to water pollution and climate change. And we can choose food that keeps local economies vibrant and farmers on their land.”

384. “I don't believe that there is anybody who denies climate change in the Democratic caucus. Everybody accepts that it is a real problem.”

385. “Here in New York, we are already seeing how climate change contributes to increasingly violent and extreme weather that has cost us dearly, in both damage and in lives.”

386. “The bottom line is clear: Climate change is a reality, and it is having a real impact.”

387. “The Millennials, a generation born digital, will have a much stronger impact on social behaviour than we currently assume. Global climate change and resource security will influence our lives in substantial ways.”

388. “The whole future, I think, of Wyoming and the economy has to do with coal and our clean coal technology, and we're going to have the ability here in Wyoming to deal with all of the things of this so-called climate change.”

389. “The EPA's climate change regulations are based on compromised scientific reports and heavily flawed data.”

390. “I don't know the science behind climate change. I can't say one way or another what is the direct impact, whether it's man-made or not.”

391. “Clinton understands that climate change is real, is caused by human activity and is one of the great environmental crises facing our planet. She knows that we must transform our energy system away from fossil fuels and move aggressively to energy efficiency and sustainable energy.”

392. “Many of the problems facing the nation and the world today may only be solved if their technical elements are understood - climate change, energy supply, health care, and infrastructure, to name just a few.”

393. “If there is an impact on climate change due to natural causes, we need to understand that, and cannot escape responsibility to deal with what we are doing now.”

394. “I am not surprised Cameron says he supports what Gillard is doing in Australia because we have, in the U.K., a totally misconceived climate change plan as well.”

395. “Climate change is a consequence of the build up of greenhouse gases over the past 200 years in the atmosphere, and virtually all these emissions came from the rich countries.”

396. “The growing evidence of climate change is forcing attention on carbon emissions and their reduction.”

397. “We cannot compromise with the earth; we cannot compromise with the catastrophe of unchecked climate change, so we must compromise with one another.”

398. “If you take energy and climate change, you really cannot deal with the problems with energy and climate change without European co-operation at a high level. If you take digitalisation, it's an obvious area where European co-operation can actually make a difference.”

399. “If we're concerned about climate change as a country, we should have policies that make sure our great-grandchildren have a planet that's healthy and strong.”

400. “Though Africa is not responsible for emitting greenhouse gases, it is suffering the consequences of climate change.”

401. “We have shared responsibility for global climate; we have to reduce climate change below 2 degrees Celsius.”

402. “Industrialised countries must take the responsibility of helping poorer countries in the climate change action plan.”

403. “If you compare Everest photographs in 1953 with its current state, things are melting. I imagine if I were a golfer in Indiana, I'd be hard-pressed to believe in climate change because nothing's going on there. But when you're up in the mountains and seeing the glaciers melt away, it's an obvious physical manifestation of a warming planet.”

404. “We can't take climate change and put it on the back burner. If we don't address climate change, we won't be around as humans.”

405. “Of course I would disagree that there's a definitive science that has concluded that mankind has turned the earth's thermostat up and that we can turn the earth's thermostat down at will, we just haven't yet found the will. That's the argument on climate change.”

406. “Placing limits on carbon pollution from power plants is about ensuring that we have clean air to breathe and communities that are safe to live in. Carbon pollution limits are about defending families who have borne the heaviest burden of the main pollutant that is driving climate change.”

407. “On climate change, we are told that there will be a civilization-ending development in the form of massive sea level rise as soon as 2050. Anybody plan to be here in 2050? I think a few of us do, myself included.”

408. “Climate change joined immigration, job creation, food safety, pilot training, veterans' care, campaign finance, transportation security, labor law, mine safety, wildfire management, and scores of executive and judicial appointments on the list of matters that the world's greatest deliberative body is incapable of addressing.”

409. “I think we're taking a snapshot view of climate change and trying to implement policy based on that snapshot.”

410. “This notion that manmade climate change is happening is wrong.”

411. “Climate change is a very real threat right now to our economy, the future of our children, to our way of life.”

413. “While some politicians argue over whether to believe scientists' almost overwhelming consensus on climate change, the business sector is a believer and is wisely planning ahead.”

414. “Addressing climate change and positioning the United States as the leader in advanced energy should be a top priority for our country and our economy, and I applaud the Obama administration for the steps it is taking.”

415. “We deserve quality jobs that pay a living wage, lower college tuition, action on climate change, and comprehensive immigration reform.”

416. “We have changing weather patterns, and we have climate change. This is the science. I hope that my party will come to be comfortable with this because we have to operate in the realm of knowledge and science.”

417. “My district has been hit with three 500-year floods in the last several years, so either you believe that we had a one-in-over-100-million probability that occurred, or you believe as I do that there's a new normal, and we have changing weather patterns, and we have climate change. This is the science.”

418. “If the Pope wants to devote his life to fighting climate change, then he can do so in his personal time. But to promote questionable science as Catholic dogma is ridiculous.”

419. “If the Pope plans to spend the majority of his time advocating for flawed climate change policies, then I will not attend.”

420. “I don't need to be lectured by the Pope about climate change.”

421. “At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?”

422. “I've become interested in the impact of climate change on the world and the future of energy needs for the developing world.”

423. “Irish research will contribute to global progress and have the potential to help all countries realise the potential of their land sectors in addressing climate change - this means reducing emissions, adapting to impacts, and enhancing and improving carbon sinks.”

424. “Building on our strong track record of supporting developing countries, including in areas like climate justice, human rights, gender and education, Ireland recognises that vulnerable communities need very considerable assistance in adapting to climate change.”

425. “Food choices are something fundamental you can control about yourself: what you take into your body. When so many other things are out of control and your influence over climate change - all these much larger issues - it's very hard to see any results or any progress. But everybody can see progress around food.”

426. “I think any thinking person should be worried about climate change.”

427. “The Department of Energy is a critical component of our efforts to curtail climate change; that work will be less effective unless we collaboratively rebuild confidence in the agency and its programs.”

428. “State government's efforts to address climate change must include reduced consumption and other conservation measures as water shortages become the new normal.”

429. “The input of Idle No More has been a lightning rod for people who were already thinking this way. We are reaching clarities on bigger issues like fracking and GMOs and climate change.”

430. “Democrats pride themselves on their commitment to science. Citing climate change, they contend that they are the party of truth, while Republicans are 'denialists.' But with respect to genetically modified organisms, many Democrats seem indifferent to science, and to be practicing a denialism of their own - perhaps more so than Republicans.”

431. “On climate change, we have only a handful of years to make massive changes, according to the scientists. The politicians have to act, and only the people can make them, because Royal Dutch Shell's not going to do it.”

432. “Both climate change and extinction are results of our tyranny over the nonhuman world and our domination of, and exploitation of, whole categories of each other - and those, in turn, are clearly linked to agriculture, the cattle-industrial complex, capitalism.”

433. “The Safari Club International has worked the legal system hard to try to keep polar bears - threatened primarily by climate change, but also by hunting - on the list of creatures people can import as trophies after shooting.”

434. “The U.N. brings everybody together. And without it, we can't deal with Ebola or terrorism or climate change. But it's 70 years old. It's tired. It's acquired a lot of bad habits. And often it feels like only new bad habits get added and old bad habits don't get taken away.”

435. “For many years now, ExxonMobil has held the view that the risks of climate change are serious and do warrant action.”

436. “We believe addressing the risk of climate change is a global issue.”

437. “We recognize that greenhouse gas emissions are one of the factors affecting climate change.”

438. “There is still significant uncertainty around all of the factors that affect climate change.”

439. “So much of what we do addresses the issues that are associated with climate change, whether it's working to reduce emissions, whether it's working to nail down our renewables, whether it's ensuring great efficiency in accessing all of our energy sources.”

440. “I'm not afraid to spend money on the R&D that's really going to move us to a cleaner energy source that I think is so much the answer to the issues of environmental responsibility and climate change.”

441. “Despite widely differing perspectives and agendas, there seems to be a remarkable global consensus that has built up over a fairly short period of time that climate change and ecology is one of the truly defining issues for humanity.”

442. “Never denied climate change. It has always changed and always will.”

443. “The whole climate change debate gives - and there are all kinds of quotes from adherents of and promoters of climate change - the reason they're doing it is it's such a great opportunity to control, you know, pretty much, government, and control your lives.”

444. “I absolutely do not believe in the science of man-caused climate change.”

445. “There's an apparent freedom, an apparent liberty of access to everything, but you can't use it because it's too much. Everything is at the same level. You even have fake news. You have to go through fake news to make up your mind. Facts and lies are treated as equal. There are even people who are against the idea of climate change.”

446. “I've grown accustomed to hotels and drastic climate change.”

447. “The jury is still out on whether humans are causing climate change.”

448. “It could be the case that all the studies supporting a warming planet are wrong; science always leaves that door open, but anthropogenic climate change remains the best explanation for a mountain of data that scientists have been poring over for a century.”

449. “Climate change denial, anti-vaccination proponents, creationist teachers, faith healers, fake bomb detector peddlers, psychic frauds, alternative medicine pushers… we need scientific thinking. We need a generation of kids who think an experiment is more important than a preconceived notion or an argument from authority.”

450. “By isolating the issues of race, gender, sexual orientation, climate change, environment, governance, economics, catastrophe and whatever other problems the present embodies or the future may bring, science fiction can do what Dickens and Sinclair did: make real the consequences of social injustice or human folly.”

451. “I have this fantasy that in future negotiations over climate change - instead of going into that room and saying, 'I'm defending Chinese interests,' or 'I'm defending Australian interests' - there will also be an identity inside of each of the negotiators thinking, 'I'm also defending human interests.'”

452. “You know, Chevron - we don't do original research on climate change. It's the government's role to do that, and we accept the determinations that are there.”

453. “We have an obligation to our men and women in uniform - and to future generations - to do something about the issue of climate change.”

454. “Many of the most science-fictional tools to fight climate change are untested, are almost impossible to truly test at planetary scale - we only have one planet after all. We're better off cutting our emissions so we don't need them.”

455. “If you had no new technology, and you powered society as we do today - mostly by fossil fuels - you'd have only two choices: Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet.”

456. “Every state that addresses climate change emboldens the others, just as shifting public attitudes embolden politicians and, arguably, the court system.”

457. “Climate change is one of those stories that deserves more attention, that we all talk about, but we haven't figured out how to engage the audience in that story in a meaningful way. When we do do those stories, there does tend to be a tremendous amount of lack of interest on the audience's part.”

458. “For someone with a background of economic justice, what scared me about climate change is not just that the sea level will rise and we'll have more storms - it's how this intersects with that cocktail of inequality and racism.”

459. “There is a triple layer of jargon when writing about climate change. You have the scientists, who are very cautious now because of the amount of climate denial. Then you have the U.N. jargon - I had to carry around a glossary of terms. It was like an alphabet soup.”

460. “If you look at the polling around climate change in this country before 'Sandy', that was kind of the low point in terms of Americans believing that climate change was real and that humans were causing it.”

461. “We have a structural problem because you can simultaneously understand the medium to long-term risks of climate change and also come to the conclusion that it is in your short-term economic interest to invest in oil and gas. Which is why, you know, anybody who tells you that the market is going to fix this on its own is lying to you.”

462. “We need to invest in healthcare, in education, in the sciences. And in so doing, we will tackle one of the most intractable problems we face, which is gross wealth inequality. We can't fight climate change without dealing with inequality in our countries and between our countries.”

463. “The Heartland Institute, which people mostly only know in terms of the fact that it hosts these annual conferences of climate change skeptics or deniers, it's important to know that the Heartland Institute is first and foremost a free market think tank. It's not a scientific organization.”

464. “Here in Canada, the people who oppose the tar sands most forcefully are Indigenous people living downstream from the tar sands. They are not opposing it because of climate change - they are opposing it because it poisons their bodies.”

465. “The more hardcore conservative you are, the more tightly identified you are with defending the interest of capital as an interest of the system based on hyper-competition, the more likely it is that you vehemently deny climate change. Because if climate change is real, your worldview will come crashing down around you.”

466. “2007, according to a Harris poll, 71 percent of Americans believed that climate change was real, that it was human caused.”

467. “As soon as you write about climate change, the first attempt to discredit you is, 'Well, you wrote this on a computer,' or, 'You took a plane to this conference.' So your opinion isn't valid.”

468. “Human-induced climate change is a scientific reality, and its effective control is a moral imperative for humanity.”

469. “As a California state legislator, I supported our cap-and-trade law to force polluters to pay for releasing harmful greenhouse gases to combat climate change.”

471. “Whether you believe in climate change or not, we want clean air. We want clean water for the American people.”

472. “As we consume more than ever, climate change is accelerating as well. In fact, we know that 2014 was the hottest year in human history. These pressures combine to create real threats to security and stability around the world.”

473. “Debate about the causes and consequences of climate change and the policy positions taken in response to it should be encouraged, not silenced.”

474. “Climate change is not an excuse to silence political speech.”

481. “Our economic future and our energy future are one in the same, and it's a future America can't shrink from. We must shape it, just as we've always done. We have to protect our planet from the threat of climate change and ensure that workers have the skills to compete for good middle-class jobs.”

482. “All the major problems of the world today are global in essence, and they cannot be solved unless through some kind of global cooperation. It's not just climate change, which is, like, the most obvious example people give. I think more in terms of technological disruption.”

483. “My hobbies are playing piano and guitar, pining for girls, worrying about climate change, pining for girls, and the poetry of John Keats.”

486. “I do think that climate change is real. And I think that it's something that we have to deal with. But I also think it has to be a balance. And, you know, as governor of South Carolina, that was what I did.”

487. “It's crazy that we happen to have a country where it depends on what political party you are in whether you believe in climate change or not.”

488. “When you run a company, you want to hand it off in better shape than you found it. In the same way, just as we shouldn't leave our children or grandchildren with mountains of national debt and unsustainable entitlement programs, we shouldn't leave them with the economic and environmental costs of climate change.”

489. “The policies we debate and enact in Congress have a real impact on people across the country. Climate change, immigration, economic inequality - each of these issues have become hot button, partisan topics, but support or opposition on these pressing issues shouldn't come down to party.”

490. “The effects of climate change are real and only getting worse. I would like to build on the promises of the Paris Climate Agreement and make our country a global leader on the fight against climate change.”

491. “Our Committee should be focusing on real priorities - improving health care, combating climate change, creating jobs and making products safer - not attacking Planned Parenthood and undermining women's access to critical services.”

492. “I will work hard at the federal level to defend our progress on climate change, but we know that forward progress on climate must happen locally.”

493. “The Paris pact was correctly described by its opponents - greens and anti-greens alike - as toothless. But it was also the first time that nations around the world had officially agreed that climate change was a problem and that concrete steps should be taken to avoid its worst effects.”

494. “Indeed, for all Donald Trump's railing about the efforts to curb climate change, nobody in his administration seems to have paid any attention to what they actually are.”

495. “Obama issued a slew of executive orders about climate change during the eight years of his presidency. Inexplicably, President Trump revoked about half of them but left the other half in place. Since Obama's orders were intertwined, it's unclear exactly what applies.”

496. “The legal fight over climate change begins in the United States with the Clean Air Act Amendments of 1977. Under the Act, the E.P.A. is required to publish a list of 'stationary sources' of air pollution, of which the most important are power plants.”

497. “City farming is not only possible, it is the very definition of the kind of meaningful, sustainable innovation we will need to meet the grand challenges of the 21st century: climate change; population growth; ageing population; urbanization; rising demand for energy, food and water; poverty; and access to healthcare.”

498. “I am gravely concerned about climate change.”

499. “Millions upon millions of secret spending by the fossil fuel industry that was unleashed by the disastrous 2010 Citizens United Supreme Court decision - this money not only fuels the campaigns of many candidates; it also represents a threat to those who don't toe the polluter line on climate change.”

500. “Climate change may not be the most important issue to every American, but strong majorities do consider it a major problem, and they aren't likely to take seriously a candidate who denies the science and who is plainly in the pocket of the polluters.”

501. “Talking to my Senate Republican colleagues about climate change is like talking to prisoners about escaping. The conversations are often private, even furtive.”

502. “The dirty secret is that climate change is not really a partisan issue in Congress.”

503. “Putting a price on carbon pollution is one of the best things we can do to stem the tide of climate change.”

504. “The American Republican Party is the last political bastion of the fossil fuel industry - now so in tow to the fossil fuel industry that it cannot face up to the realities of carbon pollution and climate change.”

505. “The Heartland Institute is about as biased as they come, and it's funded by the likes of Exxon and the Koch brothers. This is the same group that took out billboard space to compare people who understand climate change to the Unabomber.”

506. “From lying about climate change, to undermining programs that make up our social safety net, to opposing laws that reduce gun violence, to fighting marriage equality, the Kochs' tentacles infiltrate all parts of America's public debates.”

507. “The 'truthiness' of Trump's so-called facts, the questions he posed on President Obama's nationality or jobs destroyed by free trade, has the same effect as dueling scientists on issues such as obesity or climate change.”

508. “There's a growing sense among large corporations that to solve global problems like climate change, the responsibility can't fall just on the government. The business community has to be a big piece of that.”

509. “Working together, we can meet our shared goal to combat climate change. From harmonizing vehicle emissions standards to using our trading relationship to boost investment in clean energy, the actions the United States and Canada take together will help both nations meet international goals.”

510. “I would much rather we concentrated on the immediate, still-potent dangers, such as nuclear weapons, runaway climate change, and so on. Sort those out, then worry about Hal 9000.”
