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.
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.
The world's biggest challenge comes from the threats of climate change and terrorism. In India's case, terrorism is not bred in some faraway land but from across our border.
I play fictitious characters often solving fictitious problems. I believe mankind has looked at climate change in the same way, as if it were a fiction.
The main message of Climate Revolution is that climate change is caused by the rotten financial system we've got, designed to create poverty and rip off any profits for a small amount of rich people. Meanwhile, it destroys the earth.
Among all the tests President Obama faced in his first term, his biggest failure was climate change.
From floods in Iowa and Nebraska to fires in California to hurricanes in Houston and Puerto Rico, we can no longer escape the fact that climate change is not happening in some far-off, distant future.
Going meatless reduces our carbon footprint and helps us lead the way towards climate change.
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.
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.
The clear and present danger of climate change means we cannot burn our way to prosperity. We already rely too heavily on fossil fuels. We need to find a new, sustainable path to the future we want. We need a clean industrial revolution.
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.
Though Africa is not responsible for emitting greenhouse gases, it is suffering the consequences of climate change.
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.
If we are to candidly and comprehensively address climate change - which I believe is the true crisis of our time - we must find new ways to generate energy and fuel.
I have never met a geologist or leading scientist who believes adding more carbon dioxide to the atmosphere will have any significant effect on climate change.
The 'New Yorker' asked me to shoot a story on climate change in 2005, and I wound up going to Iceland to shoot a glacier. The real story wasn't the beautiful white top. It ended up being at the terminus of the glacier where it's dying.
Is there climate change? I live in the shadow of some of the greatest climate change the world has ever seen. It's called the Rocky Mountains. When the glaciers went back.
It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.
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.
