Miscellaneous Incoherent Ramblings:
Wonder how much heat all of our highways have added? (Assuming they absorb more of the sun's energy than undisturbed Mother Earth.)
How about all the heat released by burning fossil fuel?
How about all the heat released by cooking our food?
How about all the hot air released by the increasing number of human beings (some more than others!!)?
I think Mother Nature ignores us and continues her cycles of Ice Ages, etc....
