Found this excerpt in an article I read last night:
"The Vikings discovered and settled Greenland around A.D. 950. Greenland was then so warm that thousands of colonists supported themselves by pasturing cattle on what is now frozen tundra. During this great global warming, Europe built the looming castles and soaring cathedrals that even today stun tourists with their size, beauty, and engineering excellence. These colossal buildings required the investment of millions of man-hours -- which could be spared from farming because of higher crop yields."
Food for thought, that's for sure.
From H. L. Mencken:
"The whole aim of practical politics is to keep the populace alarmed -- and hence clamorous to be led to safety -- by menacing it with an endless series of hobgoblins, all of them imaginary." ~~ H. L. Mencken
Getting stuffed - and sort of feeling sick - on all this food for thought?
