Paul Krugman in today's NY Times (What about the planet?):

Our two major political parties are at odds on many issues, but nowhere is the gap bigger or more consequential than on climate.

If Hillary Clinton wins, she will move forward with the Obama administration’s combination of domestic clean-energy policies and international negotiation — a one-two punch that offers some hope of reining in greenhouse gas emissions before climate change turns into climate catastrophe.

If Donald Trump wins, the paranoid style in climate politics — the belief that global warming is a hoax perpetrated by a vast international conspiracy of scientists — will become official doctrine, and catastrophe will become all but inevitable.

So why does the media seem so determined to ignore this issue? Why, in particular, does it almost seem as if there’s a rule against bringing it up in debates?...
