Climate junk scientist Ken Caldeira: Emitting greenhouse gases is the equivalent of mugging little old ladies. Coal power plants are immoral and ought to be illegal.

Warning from climate science front lines - San Francisco Chronicle

That perspective has made [climate junk scientist Ken] Caldeira, 56, one of the world's foremost scientists studying climate change. But it's a field he turned to only after forays into philosophy, punk rock and political protest - and that spirit of art and activism continues to inform his work.
His insights have pushed him into an unusual position in the heated debate over global warming: A prominent scientist loudly advocating for sweeping public policy changes.
He's also courted controversy by pursuing and pushing for research at the outside edges of atmospheric science, exploring the possibility of manipulating the climate itself. He fears that only drastic measures might now prevent full-scale ecological disasters - if, at this point, they can be avoided at all.
...
He makes more time for journalists than many of his peers, taking pains to help the science go down with colorful sound bites and metaphors: We can no longer afford to use the atmosphere as a waste dump. Emitting greenhouse gases is the equivalent of mugging little old ladies. Coal power plants are immoral and ought to be illegal.

Caldeira sometimes struggles with the dueling roles he plays: the scientist seeking out facts; the human being who believes those findings cry out for change. But, he says, he and his peers have been outgunned for years by skeptics willing to distort the facts, while scientific findings have been demoted in the public mind to the equivalent of ideology.
