| One of Bill Watterson's _Calvin and Hobbes_ cartoons dealt with Calvin coming to the conclusion that the sun was about to go out. His dad explained the rotation of the earth about the sun, which Calvin utterly disbelieved until his mom told him the same thing. The sequence ended with, "huh, imagine ol' dad knowing something like that?"
One of the documented historical factors in climate change is a 20,000+ year cycle of the Greening and drying of the Sahara desert. This article covers many of the basics, including the very stark impact of the Earth's wobble on the climate.
Randall Munroe's cartoon from 2014 is worth mentioning, too.
Personally, I want to know what would happen if we leveled mountains inbetween the Pacific Ocean and the Great Plains, say 10 miles in width. Would that be enough to let the moisture get past the rest of the mountains? Or would that make the California water problems even worse than they are, today?
We do have the technology to level mountains (citation: Bingham Canyon Mine) - but do we have the political will to do so?
And who would we screw over by doing that? |
