Oh, by the way, the Antarctic sea ice extent set an all-time recorded history last June, with an “excess” sea ice extent of 2.06 million square kilometers.
This represents an area just under the entire size of Greenland.
True, Arctic sea ice was low the last two years, but the past two years Arctic sea ice remained all year within two standard deviations of the day-to-day normal levels. In other words, right within the range of normal weather changes.
By September, each square meter of “excess” Antarctic sea ice will be reflecting five TIMES the solar energy received up north above the Arctic.
Keep in mind that we only have satellite data on the size of the icecaps dating back to 1979. So there is no way to know what ‘normal’ fluctuations are for the icecaps over a long span of time!
We have anecdotal evidence like a picture of a US submarine floating at the north pole in the 1940’s surrounded by open water that would indicate that they do indeed fluctuate quite a bit. I like to mention this to people that belive in the global warming crap.
As for glaciers, its the same thing. There is no long term measurements and data on all of the glaciers, let alone half of them! In fact, I read that we only have long term data (>100 years) on 30 or 40 of them.
