Summer is rapidly winding down in the Arctic, and (based on DMI graphs) the region north of 80N appears set to finish the summer as the coldest on record. So far, there have only been a small handful of days which made it up to normal temperatures. The Arctic is one of many places described by climate scientists as “the fastest warming place on earth.”
Ice melt during July was the slowest in the JAXA record.
NCEP is forecasting below freezing temperatures for the next two weeks across much of the Arctic.

Solar energy received in the Arctic is in rapid decline, as the sun drops towards the horizon.

As we forecast two weeks ago, PIPS average ice thickness has bottomed out between 2006 and 2009.
Ice thickness has increased by 25% since 2008, indicating that PIOMAS claims of record low volume are probably incorrect. PIOMAS models are often used as a “data” source by global warming activists as evidence that the Arctic is in a “death spiral.”
Below are the PIOMAS forecasts for the rest of summer. PIOMAS is expecting a big melt in August, because they believe that the ice is very thin.
Next week we will start visual comparisons of actual extent vs. PIOMAS forecasts.
Ice extent is tracking below 2006 and above 2009, just as the PIPS thickness data has indicated all summer. Evidence so far points towards PIPS being a very reliable data source.

The modified NSIDC image below shows how 2010 has diverged from 2007. Green areas have more ice than 2007, and red shows the opposite.
The modified NSIDC image below shows ice loss over the last week in red. As predicted in last week’s Sea Ice News #15, there has been substantial loss in the East Siberian and Chukchi Seas. Based on NCEP weather forecasts, this will continue for at least one more week.
The next modified NSIDC image below shows the differences between current Arctic ice and September, 2006. Areas in green indicate how far the ice will have to melt back to exceed the 2006 minimum. Areas in red show where ice loss has already exceeded the 2006 minimum.
Our PIPS based forecast of 5.5 million km² continues to be right on track.
Meanwhile down south, Antarctic ice continues near record highs.

There has been much press this year about a “record polar melt” in the works. This information is incorrect, but it is seems extremely unlikely that the scientists behind those reports will make much of an effort to set the record straight.
The Arctic Oscillation is forecast to turn negative again, hinting at cooler weather in the Northern Hemisphere starting in about a week.
Much of Russia, Siberia and the former Soviet Republics are already seeing well below normal temperatures, but this is (of course) not being reported by the press.
