But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.

Stop thinking about global warming as a future threat and understand it instead as a present emergency, one that requires a far stronger policy response than we'd imagined.

Profiting from companies that are overloading the atmosphere with carbon and changing the atmosphere is wrong.

We'd like to get the fossil fuel industry on the back foot for a while, having to deal with us.

Everything that the administration has done has been counterproductive.

You can have a healthy fossil-fuel balance sheet, or a relatively healthy planet

Remember...this year has already seen more billion-dollar weather-related disasters than any year in US history. Last year was the warmest ever recorded on planet Earth. Arctic sea ice is near all-time record lows. Record floods from Pakistan to Queensland to the Mississippi basin; record drought from the steppes of Russia to the plains of Texas...This is what climate change looks like in its early stages.
