My house is covered in solar panels, I'm a great believer in all this - we all should be doing this.

In the States, the movement's actually gotten much much much stronger. There really was no climate movement so to speak before that - I think because everybody assumed that reasonable heads would prevail and do the right thing - and why would you need to have a huge movement in order to cause our leaders to deal with the most serious problem that they face. In a rational world you wouldn't. They would deal with it.

Climate change is the single biggest thing that humans have ever done on this planet. The one thing that needs to be bigger is our movement to stop it.

I think that so far the political and economic power of the fossil fuel industry has trumped all else.

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.

I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

Until it's understood to involve justice for those in poverty, a future for generations yet unborn, and a commitment to the rest of creation, it's unlikely we'll be able to overcome the status quo.
