Qualitative indicators like sea ice coverage, spring thaw dates, and melting permafrost provide strong additional evidence that trends have been positive at middle and high northern latitudes, while glacier retreat suggests warming aloft at lower latitudes.

Indeed, there is no way to truly compare ice coverage during the 1930's to 40's but the source of that speculation was pictures taken from submarines that surfaced at the north pole with considerable open waters.

You can find out more (and see links to my earlier coverage of Arctic sea - ice trends, and what's going on with sea ice at the other end of the planet) in my latest post on Dot Earth.

The marine coring record for the Arctic suggests that the Artic has never been (summer time) ice free for at least hundreds of millions of years; you'll have to find the papers and look at the extent of coverage yourself.

Given that this summer's minimum has fallen below last year's and will settle in at the 2nd or 3rd lowest on record, last summer's minimum now appears more as a bump in the road toward continuing lower Arctic sea ice coverage.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...&raquat lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...&raquAT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...&raquAT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...&raquat high northern latitudes...»

Then from 1995 to 2002, the ice area actually increased (although you would never read that in the popular press), it decreased again in 2004, and in 2005 it increased again â $ ¦ and at the end of 2005, the amount of Arctic ice was back to the 1979 - 2000 average ice coverage.

The problem is that we have only been looking at Arctic ice coverage properly during the warming phase of the 60y recurrent pattern.

When I look at the Great Lakes Ice coverage using Environment Canada Ice Service, I see regions of ice along the shores and bays and waters between islands, 0.5 % of ice coverage so fIce coverage using Environment Canada Ice Service, I see regions of ice along the shores and bays and waters between islands, 0.5 % of ice coverage so fIce Service, I see regions of ice along the shores and bays and waters between islands, 0.5 % of ice coverage so fice along the shores and bays and waters between islands, 0.5 % of ice coverage so fice coverage so far.

The report, led by scientists at the National Oceanic and Atmospheric Administration, also found that maximum winter sea ice coverage in the Arctic was the smallest ever recorded.

Morover, I think you really should look at more recent work by Polyakov — say, his 2012 paper, «Recent Changes of Arctic Multiyear Sea Ice coverage and the Likely Causes.»

Sea levels are a foot higher and Arctic ice coverage is at the lowest levels ever — the ice was gone as of March, months early.

600 At all stages, seeds of regime reversal are embedded within the collection of sub-processes regulating the Arctic freshwater balance, thereby subtly and incrementally imposing «curbs» on the prevailing trend of sea ice coverage, assuring an inevitable regime reversal years in the future.

Or look at it the other way around: if the ice cover were a record high in late summer, the opportunity for ice growth (increased area coverage) would be reduced, since there would be less open water that could freeze over.

Yet, since on rare occasion they have not seen it because it is so obvious it is worth asking about and one might even learn something Worse, in Eli's case, this is something that finally percolated through because of nonsense that Andrew Montford at Bishop Hill wrote trying to handwave the weird ice coverage this winter up north (yes, Eli knows everybunny and his brother in law is racing south to watch the Antarctic ice shelves collapse, but this is Rabett Run, Eli and Brian follow their own pipers).

If the previous melt was localised around Spitzbergen, why hasn't he offered any evidence of extensive ice coverage elsewhere at the time?

This coincided with record - breaking shrinkage of Arctic sea ice, where total coverage at the peak of melting season is now 40 percent lower than in the late 1970s.

For both summer and winter Arctic sea - ice, the area coverage is declining at present (with summer sea - ice declining more markedly; ref.

To expand the coverage of global gridded reanalyses, the 20th Century Reanalysis Project is an effort led by PSD and the CIRES at the University of Colorado to produce a reanalysis dataset spanning the entire twentieth century, assimilating only surface observations of synoptic pressure, monthly sea surface temperature and sea ice distribution.

I understand that the ice coverage in Greenland is melting now at roughly 3ft per year.

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.
