Climate change is something that we cannot fix alone - it is the original collective action problem - it will not work unless almost all the large economies of the world act together.
Abhijit Banerjee
You can't solve climate change by everybody individually buying a more efficient car and throwing out less stuff. You have to make national changes through national policy.
Adam Conover
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.
Al Franken
As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.
Al Gore
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.
Alan Lowenthal
Human-caused climate change threatens almost every aspect of human existence.
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.
Alastair Reynolds
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?
Alex Berenson
The mammoth was basically done in by climate change. The last ones survived on Wrangel Island, north of Chukotka, until 3,700 years ago. According to Eveny mythology, mammoths scooped up dirt with their tusks to form the first dry land.
Alex Shoumatoff
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.
Alex Steffen
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.
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.
Climate change is a security threat that Africans have had to deal with all of our lives.
Ali Bongo Ondimba
We need to stop being so profligate with fossil fuels, to rein back climate change and protect biodiversity. We need to work together, globally, and I'm optimistic that we will.
Alice Roberts
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.
Allan Savory
Climate change is real.
Allyson Schwartz
Diseases are a threat to us all. And so is climate change.
Alok Sharma
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.
Amory Lovins
The U.S. news media have a critical role to play in educating the public about climate change.
Amy Goodman
Beyond the borders of wealthy countries like the United States, in developing countries where most people in the world live, the impacts of climate change are much more deadly, from the growing desertification of Africa to the threats of rising sea levels and the submersion of small island nations.
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.
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.
Climate change is a fact, disrupting the environment, and also affecting economies, disease vectors, and political unrest worldwide.
America should lead in addressing climate change.
Climate change is absolutely real and if you don't believe that you ought to believe every four-star general in our military is planning for it.
Maybe this isn't a common thought that goes through one's mind when considering children, but I think about the ramifications of climate change and how the extreme weather conditions will only get worse as we keep drilling for oil and fracking for natural gas. Do I want to bring a little human into that mix?
We can help companies committed to addressing global challenges such as climate change.
Decarbonising our energy system is not some abstract regulatory requirement. It is an essential responsibility that we hold towards our children and grandchildren as the only way to effectively counter the threat of climate change.
However we choose to leave the E.U., let me be clear: we remain committed to dealing with climate change.
The U.K.'s climate change act was passed by a majority of 463 votes to three. That is really quite extraordinary. The will of parliament has rarely been expressed so strongly and unambiguously.
I believe global warming and climate change are real threats to our planet.
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.
Climate change is having a dramatic effect on the ground.
We're taking climate change seriously. But it's not the only environmental issue that we face as a planet.
I would say that California has been focused on climate change to the detriment of the other environmental programs.
The fact is that the climate changes regularly.
I just wish the California officials would focus more on cleaning up the air in their state than trying to look like they're doing something globally for climate change.
Climate change knows no borders. It will not stop before the Pacific islands and the whole of the international community here has to shoulder a responsibility to bring about a sustainable development.
Industrialised countries must take the responsibility of helping poorer countries in the climate change action plan.
We have shared responsibility for global climate; we have to reduce climate change below 2 degrees Celsius.
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.
In the United States, the world's most important democracy, Congress seems permanently deadlocked, in hock to moneyed interests, unable to grapple with the big issues of climate change, technological change, the information revolution.
The challenge lies in the fact that the planet has limited time. Be it climate change or nuclear fallout, there is very little time. You have to pick your cause.
Labor believes in sustainability. We believe in acting on climate change, not just talking about it.
Whether you believe in climate change or not, we want clean air. We want clean water for the American people.
Climate change is moving faster than we are, but we don't give up because we know that climate action is the only path.
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.
A refugee in the traditional vision is someone who flees from country to another because of persecution or conflict. But what we're witnessing now more and more is a certain number of mega-trends interacting with one another: population growth, urbanization, food insecurity, water scarcity, climate change, and conflict.
Entrepreneurs - both women and men - need equal and fair access to finance - to create new businesses, to reach to new markets, and to adapt to climate change.
Without action to de-carbonize our economies, unchecked climate change threatens to batter lives and economies around the world, hitting the poorest people hardest.
