The Intergovernmental Panel on Climate Change (IPCC) is about a year away from publishing their next Climate Synthesis Report. IPCC report drafts are about halfway through their 2 year review process. Tasty tidbits have become cannon fodder for the press. Gloom and doom is everywhere. I have read articles in my local paper, the Huffington Post and the New York Times.
The IPCC is now more certain than ever that man made carbon dioxide is seriously impacting the climate. Temperatures will rise and so will the sea level. They are now, according to the leaked data, expecting sea level to be 3 feet higher than it is today in 21oo. The recent cooler weather is being blamed on short term factors.
Hmmm…short term factors. That’s a new concept for the IPCC. It should be interesting reading. The world has not been doing as the IPCC predicted and they appear to feel the need to explain themselves. I suspect guessing.
Of course I like to guess too. My favorite guess is visible air pollution. And by that I don’t mean carbon dioxide, I mean smog. Smog blocks the Suns radiation and cools the climate and it also makes the ice in the Arctic less white, making it melt faster. And since smog is more prevalent in the Northern Hemisphere than in the Southern, it would help explain why the Antarctic has not been melting.
The National Snow and Ice Data Center states the following:
Arctic sea ice extent maintained a steady, near-average pace of retreat through the first half of August, making it highly unlikely that a new record low minimum will be reached this year. Nevertheless, there are extensive areas of low concentration ice, even in regions close to the North Pole, atmospheric pressure and temperature patterns this summer have differed markedly from those experienced in 2012; cooler than average conditions have prevailed over much of the Arctic Ocean. By contrast, Antarctic sea ice is near a record maximum extent for mid-August.
ANTARCTIC SEA ICE IS NEAR A RECORD MAXIMUM. A lot of that ice is going to have to melt. Melting in the Antarctic and Greenland are necessary for sea level to rise.
A rising sea level is a problem and a 3 foot rise is a big problem. Recent IPCC studies blame air pollution more and carbon dioxide less than does the 2007 IPCC Synopses Report. The leaked information is preliminary because it must be reviewed. That review includes a political scrubbing. And since the IPCC is a very political place I suspect air pollution will once again be ignored.
Air pollution, and soot in particular, is more of a problem in the developing world and less of a problem in the USA, so we know where the UN will come down on that issue. Don’t we?
