Canadian Ice Service, 4.7, Multiple Methods As with CIS contributions in June 2009, 2010, and 2011, the 2012 forecast was derived using a combination of three methods: 1) a qualitative heuristic method based on observed end - of - winter arctic ice thicknesses and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP) and vector wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predictoIce Service, 4.7, Multiple Methods As with CIS contributions in June 2009, 2010, and 2011, the 2012 forecast was derived using a combination of three methods: 1) a qualitative heuristic method based on observed end - of - winter arctic ice thicknesses and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP) and vector wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predictoice thicknesses and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP) and vector wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predictoSea Level Pressure (SLP) and vector wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predictoIce Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predictosea ice predictoice predictors.

We interpret the split of 2013 Outlooks above and below the 4.1 level to different interpretations of the guiding physics: those who considered that observed sea ice extent in 2012 being well below the 4.1 level indicates a shift in arctic conditions, especially with regard to reduced sea ice thickness and increased sea ice mobility; and those who have estimates above 4.1 who support a return to the longer - term downward trend line (1979 - 2007).

We interpret the split of 2013 Outlooks above and below the 4.1 median to different interpretations of the guiding physics: those who considered that observed sea ice extent in 2012 being well below the 4.1 level indicates a shift in arctic conditions, especially with regard to reduced sea ice thickness and increased sea ice mobility; and those with estimates above 4.1 who support a return to the longer - term downward trend line (1979 - 2007).

This model has been proven skillful in reproducing the monthly arctic (and Antarctic) sea ice extent anomalies over the last 30 years, as well as the observed long - term downward trend.

The trend will lead to a diminished arctic sea - ice cover.

However, it seems to me that when you add the energy involved in the atmosphere and the energy involved in melting arctic sea ice, the surface warming trend no longer shows a pause.

If you agree with me that 4 years is too short term to be meaningful for a trend of arctic sea ice extent then why are you bothering me with it?

THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing oceTREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing ocetrend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing oceans).

While the value for 2009 is near the trend line (see Stern), arctic sea ice internal conditions are considerably different from 2005.

That a simple warming trend throughout the 20th century does not characterise arctic conditions is also confirmed by records of ice cover in the four seas that lie north of Siberia (Kara, Laptev, East Siberian and Chukchi); these show clearly that ice variability in these seas is dominated by a low frequency oscillation of frequency 60 ‐ 80 years that «places a strong limitation on our ability to resolve long term trends».

While NASA says sea ice probably won't set any records this year, we have this horrible news: Sea ice decline spurs the greening of the Arctic Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientissea ice probably won't set any records this year, we have this horrible news: Sea ice decline spurs the greening of the Arctic Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientisSea ice decline spurs the greening of the Arctic Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientisSea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists.

From 1978 to 1996, the average ice cover around Antarctica showed almost no trend (a slight increase 1.3 % per decade), however ice decreased by 2.9 % per decade on average over the arctic seas (1).

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.

MODELING OF FUTURE ARCTIC SEA ICE CHANGE «Given the estimated trend and the volume estimate for October — November of 2007 at less than 9,000 km3 (Kwok et al. 2009), one can project that at this rate it would take only 9 more years or until 2016 ± 3 years to reach a nearly ice - free Arctic Ocean in summer.»
