1) People are more concerned...David, a few things:<br /><br />1) People are more concerned about Arctic sea ice loss than Antarctic sea ice gains, because it's much closer to us and has more potential to affect northern hemisphere and regional weather, jet stream. (90% of the world's population lives in the northern hemisphere.) On the other hand, Antarctic sea ice is in the middle of nowhere. The Arctic affects the NH more in terms of potential changes in the AMOC, and economically in terms of ship passages, oil drilling, etc. And people live near the Arctic Circle, so the melting there affects them in a way that Antarctic sea ice increase doens't affect anyone. The Arctic has also been studied much longer, and there's data going back a hundred years on Arctic sea ice to compare to. <br /><br />2) This article I wrote about isn't proof against AGW, though I expect some are going to try and claim it is.<br /><br />3) I don't see people ignoring Antarctic sea ice. Its expansions looks to be due to changes in winds:<br /><br />http://www.realclimate.org/index.php/archives/2014/12/clarity-on-antarctic-sea-ice/<br /><br />This year, Antarctic sea ice is way down from last year, perhaps due to the El Nino. But it's simplistic to say that the Antarctic gains are cancelling out Arctic losses, because the Arctic and the Antartic are very different places with very different geographies. Also, the trend in global sea ice extent in the satellite era is in fact -30,000 km2/yr.<br /><br />Thanks for reading my post.<br />David Appellhttps://www.blogger.com/profile/03318269033139447591noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-62469971129719198002015-11-05T07:36:15.514-08:002015-11-05T07:36:15.514-08:00Props to you, David, for linking to this article. ...Props to you, David, for linking to this article. Over the last 20 years there has been justifiable concern about the dramatic drop in Arctic sea ice extent. However, there has been less focus on the incease in Antarctic sea ice extent. The increase in the Antarctic was almost as large as the reduction in the Arctic. The obvious implication is that, although global warming is affecting polar ice, there appear to be other significant factors as well. <br /><br />Cheers<br />David in CalDavid in Calhttps://www.blogger.com/profile/10222355423128534221noreply@blogger.com
