Welcome to earth, kids

Since I had to take a science in HS, I chose geology. Liked it so much, I took geol in college. One thing I recall, those ~25,000 year ice age cycles are like clockwork, and written in stone, and we're on the cooling side of the cycle. Last year, I read how cosmic radiation causes cloud cover which causes cooling. If there's a lot of sunspot activity, more cos rad, more clouds, cooling. Low solar activity, less cos rad, fewer clouds, warming. And every 25K years, our solar system approaches a star group which increases cosmic rad significantly.

What can humankind do about this coming crisis of advancing ice, stellargenic global cooling? Put on an extra sweater and throw another AGWarmer on the fire, and hunker down for the long haul. Welcome to earth, kids.
