Some terms I seem to hear more often from man-made global warming alarmists these days are that man is "very likely" causing global warming, and that it may be at a "tipping point". Both phrases indicate a sense of desperation. Maybe the whole idea of man-made global warming itself is very likely at a tipping point.
One of the grossest distortions in American history is the claim that Herbert Hoover was a much different kind of president than Franklin D Roosevelt. He wasn't. In reality, FDR picked up his interventionist government policies right where Hoover left off--with the same sorry results.
