The thing about global warming is that you can address it on a great number of levels - in fact you have to.

The habits of the West in terms of consumption.

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet's history. We do a lot with art and music and things.

I think fracking for gas will reduce the incentive to turn to renewables, and I think it will do a lot of other damage across the countryside.

Renewable energy is far more labor-intensive than fossil fuel production.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

I guess the underlying principle might be, don't make it too easy for them to stereotype you.
