But it will again as it always has. If it didn't it would eventually take over the southern hemisphere. The point is, that when is DOES melt, the climate religionists will claim its due to AGW. They're probably saying it's our fault that the ice is again building up.
They'll never acknowledge that our planet has gone through many climate changes and climate shifts in his long history and will surely continue to do just that without any help from humankind whatsoever.
The Anazazi disappeared from our area more than five hundred years before the Industrial Revolution. I suppose it was all those ceremonial and cooking fires they lit that caused excessive CO2 that caused the extreme drought conditions, etc. that made them leave their ancestral homes?
The AGW people won't even talk about things like that. They can't even blame the cows as those didn't arrive in North America for more than a hundred years after the Anazazi left.
