...and, it is some of the same people! This piece in the New York Times is must-reading. Yet, even though the author acknowledges the 60's population forecasts were wildly wrong, he sticks to the global warming gospel. Meanwhile, the science will continue to show (here's a new study) that the expressions of "settled" climate science couldn't have been more wrong.
Why am I so confident? The climate models have run way too warm the last 20 years. Will they improve? Maybe; I don't know. But, even if global warming resumes for a climatologically significant period of time* the climate cult assumes human beings will not adapt and human ingenuity will cease.
No adaption and no ingenuity were bad bets in the '60's just as they are now.
*I expect global temperatures to rise for a year or two due to the El Nino.
