Pole to Pole Comparison

Over at The Cryosphere Today blog site, there are daily satellite pictures of the sea ice at the poles. There are also these neat graphs of the same. As anyone mildly interested in the global warming bruhaha would know, the sea ice in the Arctic Ocean is below normal. The graph shows it's down about half a million square miles from the average (the average of less than 30 years though).

How about in the South? Even though it's the start of Summer down there, the sea ice in the Antarctic Ocean is above normal, well above normal, about 2 million square miles more than what we've seen from space for the past nearly 30 years. Is the below normal area of sea ice in the North made up by the above normal area of sea ice in the South? Well, right now, yes. The global sea ice is 1.5 million square miles to the good.

What about next year? Won't the northern sea ice be behind when it starts to melt and so melt even more next northern Summer, as most true believer Warmies say? Well, not actually, in fact, for the global sea ice, even in the North, it looks pretty good. In the North, right now we're about a half million square miles better than it was last year at the same time. I'd call that a pretty decent recovery from a somewhat alarming Summer melt off in the Arctic. In the South, we've 2.5 million square miles more ice than this time last year. That's good (I guess). I mean, if melting sea ice is a sign of global warming, then increasing sea ice must be some proof that the warming is not actually global; and certainly it doesn't seem to be melting away the home of the polar bears and penguins.
