It also eliminates much of the uncertainty surrounding potentially ill effects; whereas various mathematical models may disagree about when and at what concentrations Arctic Ocean sea ice disappears, they all agree that at roughly 3 degrees C of warming, the far north will be ice - free.
The AMO is likely to be a driver of multi-decadal variations in Sahel droughts, precipitation in the Caribbean, summer climate of both North America and Europe, sea ice concentration in the Greenland Sea and sea level pressure over the southern USA, the North Atlantic and southern Europe (e.g., Venegas and Mysak, 2000; Goldenberg et al., 2001; Sutton and Hodson, 2005; Trenberth and Shea, 2006).
The forecast shows near - normal ice concentrations in the marginal ice zone and below normal ice concentrations in the polar pack, however the skill of the model north of ~ 80N isn't greater than chance.
A statistical forecast using a regression based approach with fall sea surface temperature anomalies in the North Atlantic as the main predictor was submitted by Tivy (Figure 3) for ice concentration anomalies in July in Hudson Bay.

The greatest concentration of ice, outside of Greenland and Antarctica, resides in the regions north of India and Pakistan, in the Himalaya and Karakoram glaciers.
Morison and Untersteiner (University of Washington); 5.6 Million Square Kilometers; Heuristic Estimate is based on recent observations, including the previous winter Arctic Oscillation (AO), ice concentrations observed during North Pole Environmental Observatory (NPEO) hydro surveys, atmospheric and ice surface conditions observed with NPEO buoys and Web Cams, and recent ice trajectories.
Note open water developing off Siberian and North American coastlines, and areas of low ice concentration in the central Arctic for the same day as seen in visible - range MODIS imagery (right panel, NASA MODIS Rapid Response System).
Using a statistical model based on canonical correlation analysis with fall sea surface temperature anomalies in the North Atlantic as the main predictor, Tivy shows below - normal ice concentrations throughout most of the region (Figure 12), which suggests an earlier - than - normal opening of the shipping season.
Arbetter et al. (North American Ice Service / National Ice Center); 4.9 Million Square Kilometers; Statistical / Heuristic Despite the reasonably large current extent (14.665 million km2) and compact concentration (12.461 million km2) in late April, the projected extent for mid-September is another near - record low (4.852 million km2).
Based on proxy records from ice, terrestrial and marine archives, the LIG is characterized by an atmospheric CO2 concentration of about 290 ppm, i.e., similar to the pre-industrial (PI) value13, mean air temperatures in Northeast Siberia that were about 9 °C higher than today14, air temperatures above the Greenland NEEM ice core site of about 8 ± 4 °C above the mean of the past millennium15, North Atlantic sea - surface temperatures of about 2 °C higher than the modern (PI) temperatures12, 16, and a global sea level 5 — 9 m above the present sea level17.
Another difference is that in 2013 there were areas of decreased concentration north of the Kara and Barents sea; this year, most of the Arctic sea ice prevails at higher concentrations, indicating a more consolidated and possibly thicker ice cover, which is more resilient to melt and retreat.
The AMO is likely to be a driver of multi-decadal variations in Sahel droughts, precipitation in the Caribbean, summer climate of both North America and Europe, sea ice concentration in the Greenland Sea and sea level pressure over the southern USA, the North Atlantic and southern Europe (e.g., Venegas and Mysak, 2000; Goldenberg et al., 2001; Sutton and Hodson, 2005; Trenberth and Shea, 2006).
The area around the North Pole is ice - covered — an assumption confirmed by many airborne and ice - surface expeditions — but researchers use an average of the concentration just outside the gap to estimate the extent within.
The AMSR - E image for 5 July (http://www.iup.uni-bremen.de:8084/amsr/amsre.html) is similar in extent and also shows lower ice concentrations in the Canadian Beaufort Sea and north along 130 ° E.
Continued melt of the first - year ice north of the tongue of multi-year ice in the Beaufort Sea is evident in the 16 August ice concentration map (Figure 1).
Morison and Untersteiner (University of Washington); 5.6 Million Square Kilometers; Heuristic Estimate is unchanged from last month and is based on the previous winter Arctic Oscillation (AO), ice concentrations observed during North Pole Environmental Observatory (NPEO) hydro surveys, atmospheric and ice surface conditions observed with NPEO buoys and Web Cams, and recent ice trajectories.
