The next Ice Age is upon us. Pack up and head south!
Seriously though, we are about due again for an ice age. they tend to come on rather quickly, especially in geological terms, but perhaps even in human terms.
Speaking of south though, when I left my office about 9:30 PM or so, it was 83 degrees F outside, and the humidity was 72% (felt higher) . Not sure what the high today was...but I'll check..wait one.... 91 deg (and the RH was 55 %. At 11 PM, and currently, it was/is 81 deg, 88% RH with fog. It feels like 89 degrees (RealFeel) at midnight! The first week of May! And my A/C is running! Dewpoint is rising as the temperature falls, so by morning, my car, which I just washed!, will be covered in a dried crud from the Mexican smoke being trapped in the dew, and then dried by the morning sun. Grr!
I don't care if is San Antonio! So much for global cooling too. :)
There is a novel, Fallen Angels, by Larry Niven, Jerry Pournelle and Michael Flynnthat takes as it's premise that we were overdue for an ice age, and industrial activity postponed it. Then when the econazi's got all the "greenhouse gases" and "ozone depleting" substances reduced, the ice age kicked in, with a vengance! Of course their response is "only one earth" and "conserve", resulting in yet faster growth of the polar ice caps.
IIRC, until the mid '80's all of the eco-weenies were running around saying that industrial activity was blocking the sun, and that we were on the verge of triggering a new ice age. Then, one fine day, we all started to worry about global warming, instead.
