For those so-called skeptics (read: paid propagandists) who believe that global warming isn't happening, yet another study, this time of Arctic lakes, has shown that temperatures have been rising since the beginning of the industrial revolution. One index used by the researchers was dead algae. The changes observed are compelling:
"We had thousands of years with no changes in the algae species. Now they've shown that changes occur in places where warming is going on and, more importantly, don't occur where there is no warming," one expert said.
