Sentences with phrase «sea ice reduction»

Your albedo change represents a value of about 0.17 W / m ^ 2, which if correct, would make Arctic sea ice reduction in recent years potentially a major contributor to ongoing imbalances.

To say nothing of the warming trends also noticed in, for example: * ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level rise due to all of the above * sea surface temperatures * borehole temperatures * troposphere warming (with stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects

Petrich (University of Alaska Fairbanks); 4.0 Million Square Kilometers, with a possible range of 3.4 to 5.4 million square kilometers, likely range of 3.4 to 4.9 million square kilometers; Heuristic, Statistical June sea level pressure (SLP) is related to both surface winds and clouds, which are known to drive arctic sea ice reduction in summer.

Nevertheless, it suggests that future sea ice reduction could lead to possibly important changes in oxidation over the Arctic, which could have implications for regions outside of the Arctic, under specific conditions.

Although there is a general consensus among models that rising CO2 will drive warming and continued ice melt into the future, IPCC models failed to predict the current level of rapid sea ice reduction.

Jennifer Francis of Rutgers University in New Brunswick, New Jersey, told a conference on Arctic sea ice reduction last week that a growing number of studies suggest the melting Arctic is affecting the source of these patterns: the jet stream.

He notes that the sat photos show that cloud cover remains low and that the ice is very mobile at a time when the pack should be most firm (not really a surprise since ocean temps are much more important than air temps, and apparently it's the ocean temps that have been the largest factor in the recent sharp sea ice reduction).

In particular, the models as a group considerably underestimate the recent accelerating sea ice reduction.

In fact, the evidence suggests part of the humidity increase is driven by enhanced surface moisture fluxes associated with sea ice reductions.

Petrich (University of Alaska Fairbanks); 4.0 Million Square Kilometers with a Possible Range of 3.4 to 5.4 Million Square Kilometers, Likely Range of 3.4 to 4.9 Million Square Kilometers; Heuristic, Statistical Estimate is unchanged from last month and is based on the relationship between June sea level pressure (SLP) and both surface winds and clouds, which are known to drive arctic sea ice reduction in summer.

Seierstad, I. & Bader, J. Impact of a projected future Arctic sea ice reduction on extratropical storminess and the NAO.

Observed arctic sea ice reductions can be simulated fairly well in models driven by historical circulation and temperature changes.

However, even a smaller figure (I had calculated about 0.17 W / m ^ 2 based on your inflated figure for total planetary albedo, but you can check it out) is still significant when compared with the total flux imbalance, which I think is a more informative comparison than an arbitrarily selected change in cloud cover, because it compares the sea ice reduction with the effects of all climate variations that have been operating in recent years..

Diagnosis of a 20th century simulation indicates an increased radiative forcing from aerosols and melt ponds, which could play a role in 20th century Arctic sea ice reductions.

Finally, the authors conduct sensitivity experiments using a comprehensive coupled climate model wherein they impose a sea ice reduction comparable to the observed since the 1980s.

A major lesson of the 2012 Sea Ice Outlook is that all contributors and those with objective methods underestimated the sea ice reduction, yet did note a continuing low level sea ice extent relative to previous years.

Natural Forcing Of Arctic Climate Increasingly Affirmed By Scientists Gajewski, 2015 Three years ago a cogent paper was published in the prestigious scientific journal Nature that was surprisingly candid in its rejection of the position that the substantial warming and sea ice reduction in the Arctic occurring since the late 1970s should be predominantly attributed -LSB-...]

I am sure you would agree that the local events of Greenland melting, Arctic sea ice reductions and extreme north latitude temperature anomalies have global weather and climate implications.
