Unfortunately, there's a lot of people in high places who understand the science but don't like where the policy leads them: too much government control.

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.

When we talk about climate, we need to do everything we can to set the stage before the actors come on. And they may only have one chance at success. We should keep thinking: How do we maximize that chance of success?

You get a series of super-typhoons into Shanghai and millions of people die. Does the population there lose faith in Chinese government? Does China start to fissure? I'd prefer to deal with a rising, dominant China any day.

Politicians have responsibility to act if the public opinion changes.

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

We need to start prioritizing people, not polar bears.
