Everyone should know the basic facts about our Earth’s Ice Ages. Rather than restate the facts, I offer the following basic History Channel quote with key passages my underlining:
“An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years. Thanks to the efforts of geologist Louis Agassiz and mathematician Milutin Milankovitch, scientists have determined that variations in the Earth’s orbit and shifting plate tectonics spur the waxing and waning of these periods.
Only nine years left? I’m betting we have a few million more than that.
STAND UP FOR GLOBAL WARMING!
