Not exact matches

Sea ice in the Arctic, on which arctic animals hunt, rest, and reproduce, now covers 15 % less area than it did in 1978; it has thinned to an average of 1.8 meters, compared to 3.1 meters in the 1950s.

This would certainly explain why arctic sea ice cover has been absolutely crashing in recent years while the HARDCRU / GISS global average temps had been increasing more modestly.

Will Nitschke — «why was there no increased melting of the arctic ice in 1998» — remember that the elevated global average temperature in 1998 was due to El Niño.

The weather service predicted an average to mild winter for the mid-west (Michigan), they got arctic cold and record lake ice.

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.

Actually the argument makes more sense applied to the arctic sea ice — both in winter and summer, since it is at a much higher average latitude and therefore affects albedo much less.

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)

The average arctic sea ice monthly extent for September 2012 was the lowest observed in the satellite era at 3.6 million square kilometers, based on National Snow and Ice Data Center (NSIDC) estimates — 50 % lower than the 1979 - 2000 average of 7.0 million square kilometeice monthly extent for September 2012 was the lowest observed in the satellite era at 3.6 million square kilometers, based on National Snow and Ice Data Center (NSIDC) estimates — 50 % lower than the 1979 - 2000 average of 7.0 million square kilometeIce Data Center (NSIDC) estimates — 50 % lower than the 1979 - 2000 average of 7.0 million square kilometers.

Satellite data since 1978 show that annual average arctic sea ice extent has shrunk by 2.7 [2.1 to 3.3] % per decade, with larger decreases in summer of 7.4 [5.0 to 9.8] % per decade.

Al Gore and his ilk have to keep the focus on stuff beyond the reach of the average person (like glaciers and arctic sea ice).

From 1978 to 1996, the average ice cover around Antarctica showed almost no trend (a slight increase 1.3 % per decade), however ice decreased by 2.9 % per decade on average over the arctic seas (1).

so that proves global warming, even thought the average global temp is the same as sixteen years ago and the arctic ice cap area is the highest in a decade and the Antarctic ice cap is the highest in four decades.

That's a pretty silly claim on Dr. Curry's part if you consider that in the months the arctic sea ice isn't diminished, there's never really so much sunlight as you'd count it against the average, so whatever albedo changes there are during the half of the year that matters, they're when the sun is at its highest angle.

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.

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.

Statistics Canada — Average area covered by total (all) sea ice during summer from 1968 to 2010 for sea ice regions of Arctic Domain — EnviroStats — See how clear the trends are in all of Canada's arctic regions: down, down, down at something like 7 or 8 percent a decade.
