34 Temperatures Rising due to Global Warming Effects Glaciers melting Greenland — If all of the ice melts, oceans will rise 23 feet Antarctic — major reduction in ice coverage Permafrost in Tundra is releasing CO2 that is stored under the ice
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.
Furthermore, unraveling the causes of sea ice retreat should help us understand the mechanisms behind climate change on a global level, which is interrelated to the ice reduction in the Arctic ocean.»
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).
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..
«The winds causing this trend in ice reduction were set up by an unusual pattern of atmospheric pressure that began at the beginning of this century,» Nghiem said.
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.
Given all of the ice reduction data from recent decades, this just tells you that we've been measuring temperature in the wrong places, or weighting the data wrong.
In fact, the evidence suggests part of the humidity increase is driven by enhanced surface moisture fluxes associated with sea ice reductions.
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.
Because IPCC models projected currently observed sea - ice reduction would not occur until 2070, Overland believes IPCC models were simply too conservative.
He discovered that in the Nordic Seas, the maximum extent of sea ice (April) has decreased around 33 % since 1864, much of that before 1940, demonstrating that sea - ice reduction is not a new phenomena, but began long ago.
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.
Our opinion is that preconditioning was the key factor driving the ice reduction this summer.
Wind pattern seems unfavorable for ice reduction.
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
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-...]
