It is arguably one of the most advanced of the seven in its impacts, with a 2011 GRL report putting its warming effect as equivalent to around 30 % of atmospheric anthro - CO2, and the recent report putting albedo loss from
arctic sea - ice decline since»79 as providing a forcing equivalent on
average to that from 25 % of the anthro - CO2
levels during the period.
Hi iceman, Sorry for the tardy reply, that pesky real life thing again...:) The reason there is so little excitement about the record high
sea ice extent in the antarctic (aside from it having no appealing potential victims, like polar bears) versus the record low
arctic sea ice is probably because the southern record is only a matter of 2 % anamoly, whereas in the north we are now looking at
levels over 40 % below
average.
