It now appears that the fracturing of that ice is happening much more quickly than people previously thought, apparently at a slow melt.

One degree turns out to be enough to really unhinge all sorts of earth's ecosystems.

Unfortunately, The End of Nature turns out to be correct, although I wish it were not so. The only places that I was incorrect was, as with environmental science at the time, the estimation of the speed at which we see the effects of global warming.

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 am still a consumer; the consumer world was the world I emerged into, whose air I breathed for a very long time, and its assumptions still dominate my psyche—but maybe a little less each year....There are times when I can feel the spell breaking in my mind….There are times when I can almost feel myself simply being.

I think that some of it is electoral - helping candidates that are willing to take dramatic actions, not just to say a few words about how climate change might be a problem.

We've lost half the summer sea ice in the Arctic. We've wiped out an enormous percentage of the world's coral reefs. We see huge changes in the planet's hydrology already, the cycles of drought and flood both amped up because warm air holds more water vapor than cold. These things are happening with a one-degree increase and going to two degrees won't be twice as bad, the increase in damage won't be linear, it most certainly will be exponential. So it was precisely the wrong moment to elect Trump.
