Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year.

I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change. The inertia of humans is so huge that you can't really do anything meaningful.

The evidence for human-made climate change is overwhelming.

There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

I'm not a pessimist, even though I do think awful things are going to happen.

The climate is doing its usual tricks. There's nothing much really happening yet. We were supposed to be halfway toward a frying world now.
