Geoff Beacon # 19: To answer your question, if you mean you expect the NSIDC to announce a September arctic sea ice minimum below, say 1M sq km, by 2015, I would bet against, but not a huge amount, because of uncertainty.

Current ice extent is well below levels at the same point in 2012, which went on to set the current record for the lowest sea ice minimum extent:

This means the expectation is that the minimum Arctic Sea Ice extent this year will be below that of 2007.

My bet is that this year's Arctic Sea ice extent ice will not fall below last year's minimum (4.28 or 2.77), because last year's minimum was very low in comparison to all other years of record (1979 - current).

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.

Given that this summer's minimum has fallen below last year's and will settle in at the 2nd or 3rd lowest on record, last summer's minimum now appears more as a bump in the road toward continuing lower Arctic sea ice coverage.

In the summer of 2012, Arctic sea ice has broken the previous record for minimum extent (set in 2007), fallen below 4 million square kilometers, and, as of September 17, dropped below 3.5 million square kilometers in extent.

Total sea ice extent for the previous three months was near or below the level of 2007, the year with the lowest minimum summer ice extent during the satellite record.

It is also important to note that although recent sea ice values have not reached the extreme minimum of 2007, the sea ice minimum has remained well below the long - term «norm» (Figure 1).

It is important to note that the sea ice minimum has remained well below the long - term average every year since 2007 (Figure 1).

It is important to note that the sea ice minimum has remained well below the long - term average every year since 2007.

53 % of the Outlook contributions suggest the September minimum will remain below 5 million square kilometers, representing a continued trend of declining sea ice extent.

Reasoning for a decrease in sea ice extent from recent years, perhaps approaching new record - low minimum, focuses on the below - normal sea ice thickness overall, the thinning of sea ice in coastal seas, rotting of old multi-year sea ice, warm temperatures in April and May 2010, and the rapid loss of sea ice area seen during May.

Reasoning for a new record minimum focuses on the below - normal ice thickness overall, the thinning of sea ice in coastal seas, rotting of old multi-year sea ice, and the rapid loss of sea ice area seen during May.

Sea ice extent for September 2007 was 4.3 million square kilometers — a reduction of more than 40 % from the 1980s and a rapid decline to more than 20 % below the previous record minimum.

Below are several projection ensembles for future minimum summer sea ice extent (Fig. 7).

The current sea ice extent is below 4 M sq km, and apparently a minimum has not yet been reached, although a minimum around 3.5 M sq km seems likely.

At minimum sea ice extents near the equinox, the sun is below the horizon for 12 hours each day, and rises only a little bit (less than 10 degrees) above the horizon for a few minutes each day at solar local noon.

The paper questioned whether climate change was dangerous for polar bears and whether the region was warming at all, even as NASA reported that the 2007 minimum sea ice levels were at an all - time low, falling to nearly 40 percent below the 1979 - 2000 average.
