You may not think the expected consequences of climate change are bad enough to do anything, despite what researchers have been telling us for years about higher temperatures, worsening frequency and intensity of storms and droughts, rising sea levels, altered water quality and availability, growing health risks from pests and heat, and much more.

Fine. But you are dragging the rest of us, who still believe in science and think that things can and should be done quickly, down into what increasingly seems like a future hell. […]
