In my relatively short lifetime the scares have already been through a 'coming ice-age' to 'catastrophic warming' to 'climate change' cycle. The latter being a good catch-all I suppose.
This is more logical fallacies. Just because some very small percentage of scientists talked about global cooling doesn't discount the overwhelming current consensus going on now.
So you are a solar cycle denier? How retrograde.
"Very small percentage" = appeal to popularity (a logical fallacy)
You are obviously too young to remember the long procession of hobgoblins used to justify destroying freedom, from the neo-Malthusian population bomb and ice age panics of the 70s, and the catastrophic warming and nuclear winter of the 80s, to the climate change of the 90s.
You are scared witless of whatever fashionable new bogeyman the Fabians and Frankfort School throw out this decade.
You may relax, dear child, because none of those instances of catastrophism (which are merely secular versions of eschatology) have come to pass.
If we get wiped out, it will be by sudden planetary (think supervolcanic) or astrological (giant meteor of doom) factors beyond our control.
So spare us the hubris, and especially the accusations that doing nothing = violence. Don't press that specious nonsense in my face or you'll get cut.
