When I was in grad school long ago, the same crowd of "Henny Penny" scientists were saying that there was an ICE AGE coming within 10 years & that we "just have to" spend TRILLIONS of dollars to deal with the "coming ice age".
(Did I sleep through the "ice age" that the "Global Cooling fanatics/loons" were "so very sure of" & warned us against in the 1980s??)
Frankly, given the large amount of outright LIES, "wild guesses" & knowing silliness of "the global warming crowd" I'm very dubious of their "trusted scientific data".
(Fwiw, there are NO "drowning polar bears" nor is there any "hard data" to PROVE many of the other wilder claims made by the "consensus of experts".)
I suspect that the ground is getting harder only because I'm now 70YO, instead of 25YO. - Fyi, my bones DO ache in the mornings.
just my OPINIONS, satx
