Some have written that skeptics don’t cover sea ice in summer, that’s not how it works here. Lately, we’ve seen a bit of consternation in the news and on blogs over the rate of drop in Arctic sea ice. As usual it’s nothing scary to me, but if it continues, the headlines are going to provide a bit of entertainment by September. According to the NSIDC data collected by UIUC, the Arctic is 1 million sq kilometers below what would make the polar bears happy.
A higher resolution but shorter time period dataset for the Arctic (AMSR-E data JAXA) for this year (red line) started a few months ago above the 8 previous years but has crossed all but 1. What I find interesting is the difference in slope between 2010 and previous years. The melt rate appears fast.
The warm Atlantic surface water may have something to do with it, again a bit of waterflow causes a big change. Another interesting feature of sea ice globally is what’s going on in the Antarctic.
While the Arctic ice plunged the Antarctic sea ice has launched vertically growing 1m km in a very short period. Looking at the graph, it doesn’t appear unheard of but it’s a pretty fast climb rate. All this excitement leads to a global sea ice anomaly level of–
In fact all of our global warming has currently lead to 0.08/20 = 0.4 percent loss of sea ice, of course the sea ice varies by 25% every year so I wonder what percentage of that 0.4 is due to natural vs man made warming?
Of course amongst all that huge melting, we get stuff like this.
Last message from Arctic
It looks like the Arctic is sending us one last message. One last warning about the effects that mankind would face because of the external abuse of the ecosystem and the arrogance that humans show regarding such an important issue.
I placed the link on the period of ‘this’ above, to prevent inadvertent clicking on the article this nonsense quote came from. That way you can’t sue me for the guaranteed loss of IQ points if you read it.
