U.S. cases of anal cancer have risen 37 percent in the last 10 years
The earth has warmed in the past 50 million years. It has had various Ice Ages and temperatures have risen and fallen in the past, but it has never had the rapid rise in temperature that we are now experiencing since the Industrial Revolution, 200 years ago, global warming.
