Global warming and cooling, according to our more down-to-earth earth sciences scientists, seem to occur in 1500-year cycles. People's lifespans, something like 35 years or so for century after century before capitalism came along and, much to the chagrin of lefty hollowhead Marxist anti-capitalists who still blindly deny it, extended the average life expectancy out to 70 or 80 years or so, was just too short for people grubbing in the ground for their grub in the form of grub worms to take much notice of these great climate shifts.
