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.

Results show that the globally and annually averaged radiative forcing caused by the observed loss of sea ice in the Arctic between 1979 and 2007 is approximately 0.1 W m − 2; a complete removal of Arctic sea ice results in a forcing of about 0.7 W m − 2, while a more realistic ice - free - summer scenario (no ice for one month, decreased ice at all other times of the year) results in a forcing of about 0.3 W m − 2, similar to present - day anthropogenic forcing caused by halocarbons.

This is a decrease from the average rate of ice loss for June 2010 of -85,210 square kilometers per day, and is slower than climatology (average of -84,050 square kilometers per day for 1979 - 2000).

Furthermore, the Arctic has warmed more than twice as fast as the global average, a phenomenon known as Arctic amplification, and stimulated by the combined increasing Arctic temperatures and rapid loss of sea ice in all seasons along with declining snow cover in the spring and early summer.

Air temps in arctic are almost precisely the same as the average for the past 50 years — So it is unlikely air temps have created ice loss — BUT CONVERSELY — the increased open arctic water SHOULD be affecting the arctic air temp - but is not (large expanses of 1 degree C arctic water make it difficult for air temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the year)
