What caused the global warming that ended the last ice age? It must gave been all of those proto humans driving thier gas guzzling SUVs and all of the smoke belching factories they were running. Maybe it was wooly mammoths passing gas.
LOL, yeah it's been getting warmer for the last 10,000 years. otherwise we'd be freezing.
but no matter what we do, Russia, India, China etc. are not doing anything and that air moves around the globe just like that sunami junk from Japan.
