Climate change isn't just an environmental issue; it's a technology, water, food, energy, population issue. None of this happens in a vacuum.

If you start getting instability in large powers with nuclear weapons, that's not a good day.

Most people out there are just trying to keep their job and provide for their family. If climate change is now a once-in-a-mortgage problem, and if food prices start to spike, people will pay attention.

Politicians have responsibility to act if the public opinion changes.

People working on climate change should prepare for catastrophic success.

I see climate change as one of the driving forces in the 21st century. With modern technology and globalization, we are much more connected than ever before. The world's warehouses are now container ships.

I like to think of climate action as a three-legged stool.
