I've been getting mail about how science is fixing the planet ...personally, I'm a climate change guy...but it's been changing for thousands of years. There hasn't been a thousand year period that the climate has stayed the same...well...maybe 2 billion years ago...when it was ice from pole to pole...and then the 500k period just after that when the planet was ice free. But in modern times (in a geological sense) the swings have been pretty constant. The makers are in 22000...the badness happened 20000 years before that. lessee...22000 minus 20000 equals 2000. two thousand years from now...yeah...at the rate we're going...we're in deep shit.
