We consider it vital that the community of nations be drawn together in an orderly, disciplined, rational way to review the history of our global environment, to assess the potential for future climate change, and to develop effective programs.
I really wanted to address different issues of protection of biodiversity, water management issues that I knew were pretty severe in most countries, and then of course climate change.
I support a Green New Deal to put people to work building a renewable green energy infrastructure that can help us fight climate change and protect our communities.
Obama has been saying for years now - he said it again on Sunday - that climate change is the biggest threat facing the planet, all the while he knew that Iran is just a couple months away from a nuclear bomb.
Trump's corporate tax reform would restore America's position as the most hospitable investment climate in the world. For a change, businesses and their cash would come back home.
Will we confront climate change in time or will we let fossil fuel companies determine our fate? This is a fight we can't afford to lose, and that's what keeps me moving forward.
The direct risks from climate change are obvious: as changing weather patterns cause extremes of flood and drought, hurricanes and typhoons. These damage the physical infrastructure of buildings and bridges roads and railways. They are violent and disruptive.
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.
Whether you believe in climate change or not, we want clean air. We want clean water for the American people.
...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.
I think that the climate change policy and strategy that we have developed and that we have rolled out thus far is an example of incredibly high-quality work, incredible collaboration by an exceptionally large number of well-informed people.
We've polluted the stratosphere with these chlorine and bromine compounds, and because it's now colder, and because we have this change in the climate, we're getting more ozone loss than we would have gotten in a normal year.
It's this kind of wild unpredictability, megalomania, thin-skinned craziness that really has me worried, more than [Donald Trump] statements. Now, on the climate change there's just nothing to say, he's perfectly straightforward.
New York City is one of the most vulnerable cities in the world to climate change, so I see Keystone as the central threat to New York.
We have to fix climate change with the people we have right now, and to a large extent with the perspectives we have right now as well.
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.
While we would not want to attribute every extreme weather event to climate change - the pattern is building and the costs are rising - the human costs and the financial costs
We have emails from donors. We got thousands and thousands of emails here that have been leaked and dumped, and I can't find any reference to climate change.
Runaway climate change would condemn millions to a life of poverty and cause us to fail to meet the Sustainable Development Goal of eradicating extreme poverty by 2030. This is not an acceptable outcome.
A new study says that working fewer hours can slow global warming. So you know what that means? President Obama's economic policy is also his climate change policy.
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.
There's only one way we're going to change our political climate and ensure we establish some respect in our discourse. And that is to show there is a real price to pay for being a disrespectful partisan idiot.
The fact that communities that are relatively powerless often are exposed to more dangerous pollution and the worst effects of climate change: a society like that is one that is less free and less equal for everybody.
The climate is not tomorrow. The climate is a year off or maybe 10 years off. So we have to be really clear that we're solving the crisis of economic insecurity at the same time.
I believe that man does have an impact on the climate, that CO2 has an impact on the climate, and we do take that seriously.
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.
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.
I have long been something of a climate-change sceptic, but my views in recent years have shifted. For me, the most convincing evidence that something worrying is going on lies right here in the Arctic.
The problem with climate change has always been that whilst political timeframes and economic investment timeframes work on a 3-5year cycle, the planet needs a rather longer term view.
Those people on the other side, they will answer any question about climate change by saying, 'I’m not a scientist.' Well, I’m not a scientist either. I’m just a grandmother with two eyes and a brain.
As a professional snowboarder, my livelihood obviously depends on snow. And for me, traveling around the world, chasing the snow, I see the effects of climate change first hand. You can tell the difference.
More and more Americans are experiencing the direct impacts of climate change, from the wildfires in California, to devastating hurricanes in the Southeast, to drought in the Southwest. And they are choosing candidates who are ready to do something about it.
When I listen to the public debates about climate change, I am impressed by the enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories.
In fact global warming has stopped and a cooling is beginning. No climate model has predicted a cooling of the Earth – quite the contrary. And this means that the projections of future climate are unreliable.
As for companies invested in the space - I think its important to distinguish between a good investment and a material climate change technology - you can have the first without the second, even in the "clean tech" space.
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.
I believe, along with Pope Francis and almost all scientists, that climate change is threatening this planet in horrendous ways, and that we have to be aggressive in transforming our energy system away from fossil fuel and defeat the Keystone Pipeline.
Is it just me, or did 2019 feel like an endless fight? Tension over Brexit and climate-change protests trickled down into our everyday lives, putting pressure on every relationship.
We must incorporate climate modelling in future plans and investments. Whether it is policies on crop procurement, skilling and job creation, urbanisation or even beach tourism, climate adaptation pathways will have to be imagined.
People have taken advantage of the very well-trodden pathways that divide science and faith on other issues, such as creation, evolution, and the age of the universe, to pigeonhole climate change as yet another variant on the same theme.
My hobbies are playing piano and guitar, pining for girls, worrying about climate change, pining for girls, and the poetry of John Keats.
I don't feel passionately about politics, i'm not a political person. Is it easy for me to get fired up about someone's position on climate change? No, it's not. On most of these issues, I can see both sides.
The most important thing to understand about Trump's withdrawal from the Paris Climate Change agreement is, whilst it undeniably damages the rest of the world, it does most damage to America itself.
The obvious reductio ad absurdum is Holocaust deniers: Should their perspective be provided, for "balance," any time someone writes about the Holocaust?
I think that if we want to cure cancer, we have to teach girls to code. If we want to do something about climate change, we have to teach girls to code. If we want to solve homelessness in our city and our country, teach girls to code. They're change makers.
Portland took the lead on climate action more than 25 years ago when we became the first U.S. city to adopt a climate action plan.
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.
Responding to climate change will become the obsession of the next decade in much the same way terrorism was this decade's obsession.
There are a lot of reasons people don't talk about climate change. One of them has to do with the language of science, and people feeling not competent about this issue.
If substantial methyl hydrate melt begins to occur in the Arctic Ocean basin, then the (carbon) accelerator will be jammed, and there will be nothing we can do to cut the speed of climate change.
Climate change is more remote than terror but a more profound threat to the future of the children and the grandchildren and the great-grandchildren I hope all of you have.
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.
Climate change and air pollution know no borders, and antibiotics resistance respects no boundaries. Bacteria from Africa can make people in America sick. The burning of Indonesian forests can keep Asia gasping for breath.
The trouble is that the hockey stick graph become an icon and deniers reckoned if they could smash the icon, the whole concept of global warming would be destroyed with it.
Climate change is sometimes misunderstood as being about changes in the weather. In reality it is about changes in our very way of life.
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.
I think if we're going to be serious as a city, as a country, about addressing climate change, addressing inequality and racial disparities, we have to start taking action at the scale that matches the urgency of the problems.
My job as energy and climate change secretary is to both power the country and protect the planet. Nuclear power delivers on both of these objectives.
World Migratory Bird Day is an opportunity to celebrate the great natural wonder of bird migration - but also a reminder that those patterns, and ecosystems worldwide, are threatened by climate change.
I attended the climate talks in Copenhagen in 2009, and back then, national governments waited until days before to submit climate plans, and the U.S. based its pledge on a proposed bill that would fail in the Senate.
