I’ve never met a competent scientist or engineer who buys into the “Global-Warming” theory. I have met many who admit not haviineen adequate evidence and might withhold doubt.
Environmentalism is attractive to the Left for the same reason that Socialism and Communism appeal. The theory, no matter how divorced from rality it may be, is irrestibly attractive to them.
I know one electrical engineer who bought into it for quite awhile.
He was an avid reader of science magazines - and who was I to tell him those magazines can be “spin” too.
A book came along called Red Hot Lies. He had a complete turnabout after that.
I haven’t read that yet, must be good.
