We have to fix climate change with the people we have right now, and to a large extent with the perspectives we have right now as well.

If we smoke, there's no magic number of cigarettes, or number of years, that we can smoke before we know we'll get lung cancer.

There is no set period of time or total amount of carbon emissions that we can stay below to ensure we stay safe.

It's a common perception that science and religion are mutually exclusive. But there are many scientists who would consider themselves to be spiritual people.

Where I live, if I put solar panels on my roof I'm not allowed to sell that energy back to the grid. I can't change that restriction myself. I need our local decision-makers to fix that.

We need a price on carbon that accurately reflects its real costs on our society and our wellbeing.

I've even had people tell me that I must not be a Christian because I think climate change is real. But you know, there's nothing in the Bible that says that. The sad truth is that our thought leaders - many of them in the conservative media and politics - are the ones telling us this isn't real, and we are believing them.
