            "description": "The maximum Arctic sea ice extent appears to have occurred on February 25, 2015, reaching an extent of 14.52 million square kilometers (5.61 million square miles).  If the February 25 value holds, it would be one of the earliest maximums on record, 15 days earlier than normal, and the lowest extent in the satellite record starting in 1979. It is 129,500 square kilometers (50,000 square miles) below the previous lowest maximum recorded in 2011. Overall, there is a declining trend in the maximum extent of about 2.5 % per decade. This is much smaller than the summer trends, but also reflects the long-term warming trend in the Arctic.<br><br>While a low maximum gives the extent a head start heading into summer, it turns out that there is very little relation between the maximum and summer minimum and a record low maximum does not portend a record low minimum. This is because the ice near the edge at the time of the maximum is thin, seasonal ice that will melt out early in the summer. The weather conditions in the Arctic during the summer melt season is the most crucial in determining whether a record low is possible in any given year.",

            "description": "The sea ice cap of the Arctic appeared to reach its annual maximum winter extent on February 25, according to data from the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.61 million square miles (14.54 million square kilometers), this year’s maximum extent was the smallest on the satellite record and also one of the earliest.Arctic sea ice, frozen seawater floating on top of the Arctic Ocean and its neighboring seas, is in constant change: it grows in the fall and winter, reaching its annual maximum between late February and early April, and then it shrinks in the spring and summer until it hits its annual minimum extent in September. The past decades have seen a downward trend in Arctic sea ice extent during both the growing and melting season, though the decline is steeper in the latter.This year’s maximum was reached 15 days earlier than the 1981 to 2010 average date of March 12, according to NSIDC. Only in 1996 did it occur earlier, on February 24. However, the sun is just beginning to rise on the Arctic Ocean and a late spurt of ice growth is still possible, though unlikely.If the maximum were to remain at 5.61 million square miles, it would be 50,000 square miles below the previous lowest wintertime extent, reached in 2011 at 5.66 million square miles — in percentages, that’s less than a 1 percent difference between the two record low maximums. In comparison, the swings between record lows for the Arctic summertime minimum extent have been much wider: the lowest minimum extent on record, in 2012, was 1.31 million square miles, about 300,000 square miles, or 18.6 percent smaller than the previous record low one, which happened in 2007 and clocked at 1.61 million square miles.A record low sea ice maximum extent does not necessarily lead to a record low summertime minimum extent.“The winter maximum gives you a head start, but the minimum is so much more dependent on what happens in the summer that it seems to wash out anything that happens in the winter,” said Walt Meier, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “If the summer is cool, the melt rate will slow down. And the opposite is true, too: even if you start from a fairly high point, warm summer conditions make ice melt fast. This was highlighted by 2012, when we had one of the later maximums on record and extent was near-normal early in the melt season, but still the 2012 minimum was by far the lowest minimum we’ve seen.”The main player in the wintertime maximum extent is the seasonal ice at the edges of the ice pack. This type of ice is thin and at the mercy of which direction the wind blows: warm winds from the south compact the ice northward and also bring heat that makes the ice melt, while cold winds from the north allow more sea ice to form and spread the ice edge southward.“Scientifically, the yearly maximum extent is not as interesting as the minimum. It is highly influenced by weather and we’re looking at the loss of thin, seasonal ice that is going to melt anyway in the summer and won’t become part of the permanent ice cover,” Meier said. “With the summertime minimum, when the extent decreases it’s because we’re losing the thick ice component, and that is a better indicator of warming temperatures.” || ",

            "description": "LEAD: Scientists say the 2015 Arctic sea ice maximum annual extent is lowest on record.1. Observations from the NASA–supported National Snow and Ice Data Center indicate the winter sea ice has peaked at 5.6 million square miles, less than twice the size of the U.S.2. The main player inhibiting growth are the warm winds from the south that compact the ice northward and also bring warm air that melts the ice.3. The end of the winter ice growth season came two weeks earlier compared to the 1981 to 2010 average date.TAG: The past decades have seen a downward trend in Arctic sea ice during the winter and summer, although, the trend is decreasing faster for the summer melt. || WC_ArcticMax-1920-MASTER_iPad_1920x0180_print.jpg (1024x576) [139.7 KB] || WC_ArcticMax-1920-MASTER_iPad_1920x0180_searchweb.png (320x180) [92.0 KB] || WC_ArcticMax-1920-MASTER_iPad_1920x0180_web.png (320x180) [92.0 KB] || WC_ArcticMax-1920-MASTER_iPad_1920x0180_thm.png (80x40) [6.6 KB] || WC_ArcticMax-1920-MASTER_WEA_CEN.wmv (1280x720) [8.1 MB] || WC_ASIM_.avi (1280x720) [10.6 MB] || WC_ArcticMax-1920-MASTER_baron.mp4 (1920x1080) [14.5 MB] || WC_ArcticMax-1920-MASTER_iPad_960x540.m4v (960x540) [38.8 MB] || WC_ArcticMax-1920-MASTER_iPad_1280x720.m4v (1280x720) [64.1 MB] || WC_ArcticMax-1920-MASTER_iPad_1920x0180.webm (1920x1080) [2.8 MB] || WC_ArcticMax-1920-MASTER_NBC_Today.mov (1920x1080) [125.3 MB] || WC_ArcticMax-1920-MASTER_iPad_1920x0180.m4v (1920x1080) [125.3 MB] || WC_ArcticMax-1920-MASTER_prores.mov (1920x1080) [463.9 MB] || WC_ArcticMax-1920-MASTER_1920x1080.mov (1920x1080) [564.0 MB] || WC_ArcticMax-1920-MASTER_1280x720.mov (1280x720) [672.4 MB] || ",

Observations from the NASA–supported National Snow and Ice Data Center indicate the winter sea ice has peaked at 5.6 million square miles, less than twice the size of the U.S.2. The main player inhibiting growth are the warm winds from the south that compact the ice northward and also bring warm air that melts the ice.3. The end of the winter ice growth season came two weeks earlier compared to the 1981 to 2010 average date.TAG: The past decades have seen a downward trend in Arctic sea ice during the winter and summer, although, the trend is decreasing faster for the summer melt.",
