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.
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.
Migrants all over the world are pushed and pulled across borders by hunger, terror and climate change. It happened to my own family.
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.
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.
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.
How we grow food has enormous effects on the environment - climate change as well as pollution of air, water, and soil.
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.
We must recognize that Small Island Developing States are particularly vulnerable to climate change, natural disasters, and external shocks.
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.
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.
We are all living together on a single planet, which is threatened by our own actions. And if you don't have some kind of global cooperation, nationalism is just not on the right level to tackle the problems, whether it's climate change or whether it's technological disruption.
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.
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.
We must not sacrifice one of our remaining untamed places in reckless pursuit of oil. We know we have to leave oil in the ground, or destructive climate change will become unstoppable. If not in the pristine and vulnerable Arctic Ocean, then where?
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.
No matter what Sarah Palin and these geniuses she surrounds herself with try to tell you, climate change is not a liberal versus conservative thing, but the people who profit from ignoring it want you to believe it is.
This whole climate change and what it's doing to our environment is frightening to people.
With our evolved busy hands and our evolved busy brains, in an extraordinarily short period of time we've managed to alter the earth with such geologic-forcing effects that we ourselves are forces of nature. Climate change, ocean acidification, the sixth mass extinction of species.
Public discourse has been polluted now for decades by corporate-funded disinformation - not just with climate change but with a host of health, environmental and societal threats. The implications for the planet are grim.
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.
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.
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.
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.
I've grown accustomed to hotels and drastic climate change.
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.
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.
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.
As is widely accepted, putting a price on carbon pollution is the lowest cost and most efficient way to tackle dangerous climate change.
Among all the tests President Obama faced in his first term, his biggest failure was climate change.
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.
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.
The evidence for human-made climate change is overwhelming.
I think you could offer seven or eight different possible ends for energy policy. Climate change is one of them. Dealing with criteria pollutants is one of those related to that.
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.
The best way to tell people about climate change is through non-fiction. There's a vast literature of outstanding writing on the subject.
