Artic sea ice minimum has been retreating over the past thirty years (shown in yellow).
As a result, the sea ice volume at its annual minimum has declined 75 % over the past three decades.
The graph below (high - resolution copy) shows the range of the forecasts for early September, the point when the sea ice typically reaches its minimum extent, compared to recent years and the average over the period of precise satellite measurement.
And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...
Arctic sea ice extent (SIE) has decreased over recent decades, with record - setting minimum events in 2007 and again in 2012.
Depending on how the weather plays out over the next few weeks, that minimum is likely to fall somewhere between second and fifth place, they estimate — still a remarkably low level that shows how precipitously sea ice has declined in recent decades.
They collectively conclude that recent September sea ice minima are more related to longer term shifts in thermal forcing and ice melt and thus persistence, and in most years, month - to - month meteorological variability over the summer months tends to cancel out extremes in atmospheric forcing.
Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..
Both 2007 and 2008 qualify as major outliers compared to previous summer minimum sea ice extents over the last three decades.
Satellite data reveal how the new record low Arctic sea ice extent, from Sept. 16, 2012, compares to the average minimum extent over the past 30 years (in yellow).
The very small change in ocean water temperatures since sea ice measurements began in 1979 does not match with gains (or losses) in any season, not from Sept (Arctic sea ice minimum) over through winter to March - April sea ice maximums.
Although there is general consensus in the September Outlook for either persistent conditions or a slight increase over the 2008 sea ice extent, Outlook contributions which provide probabilistic assessments indicate about a 20 % chance of reaching a new September sea ice minimum in 2009.
Although the majority of the responses indicate either persistent conditions or a slight increase over the 2008 sea ice extent, there appears to be about a 20 % chance of reaching a new minimum in 2009.
Behavior of the sea ice over the past winter and the spring and the large positive temperature anomalies in the Arctic (as high as 20 degrees C over large regions in the past winter) suggest that an extent near that of the 2012 minimum may occur again if there is large export of sea ice out to the Atlantic Ocean via the Fram Strait.
NASA satellites have seen the minimum summertime sea ice coverage decline by 13 percent over the last three decades, along with a decline in sea ice thickness.
Since the graph isn't fine grained enough to track runs year - to - year, it will be interesting to see if we do experience a resurgence in sea ice growth over the next couple of years or if melt just goes straight to the expected minimum of around 1m km2.
The annual mean Arctic sea ice extent decreased over the period 1979 to 2012 with a rate that was very likely in the range 3.5 to 4.1 % per decade (range of 0.45 to 0.51 million km2 per decade), and very likely in the range 9.4 to 13.6 % per decade (range of 0.73 to 1.07 million km2 per decade) for the summer sea ice minimum (perennial sea ice).
Yes, after an autumn in which the sea ice extent curve has tracked pretty closely with 2007 — which ended up with a record - low minimum — we have had a sharp increase in extent over the last few weeks.
Ice extent in the Beaufort, Chukchi, and East Siberian Seas remain high compared to the 2007 record minimum, however, the overall ice extent could still rival the 2007 record minimum particularly if winds over the next few weeks push the ice northwaIce extent in the Beaufort, Chukchi, and East Siberian Seas remain high compared to the 2007 record minimum, however, the overall ice extent could still rival the 2007 record minimum particularly if winds over the next few weeks push the ice northwaice extent could still rival the 2007 record minimum particularly if winds over the next few weeks push the ice northwaice northward.
