There is a whole side topic of how liberals really are retrogrades and luddites. AGW is essentially a statist orthodox solution very similar to worshipping failed New Deal economics (it failed in the 30′s as well).
Keynes died depressed by his policy failures and the state of English debt ratio in what 1946? Has western economic dogma “progressed” since that time in the hand of these people who worship IPCC central planning?
They’re banking on windmills and rationing as a policy solution? They can call this “progressive” with a straight face? It’s a nostalgia movement as a rule. Has-beens.
