Researchers released a report this week revealing “ultralow surface temperatures” in East Antarctica that surpass the coldest temperatures ever recorded on the earth’s surface.

The lowest measured air temperature on earth is −89.2 °C (−129 F) on 23 July 1983, observed at Vostok Station in Antarctica, but new data published in Geophysical Research Letters this week, has found that some 100 different locations on the East Antarctic Plateau reached temperatures of -98° C (-144° F) during the Antarctic polar night between 2004–2016.

A team from the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have identified the East Antarctic Plateau — a massive, empty expanse the size of Australia that begins near the South Pole — as the coldest place on the planet.

The East Antarctic Plateau sits some 3,500 m (11,500 ft) above sea level and the air over the Plateau is extremely still, dry and thin, providing an ideal environment for extreme cold.

“In this area, we see periods of incredibly dry air, and this allows the heat from the snow surface to radiate into space more easily,” said Ted Scambos of the University of Colorado Boulder, lead author of the study.

East Antarctica is home to extremely low air and surface temperatures brought on by intense radiative cooling of the snow surface during prolonged wintertime periods of clear sky, weak winds, and very dry atmosphere, the report revealed.

The researchers analyzed data from NASA’s Terra and Aqua satellites, as well as the NOAA’s Polar Operational Environmental Satellites, gathered during the Antarctic winters between 2004 and 2016, and found that snow surface temperatures regularly dipped below -90° C (-130° F) across the Plateau, with some 100 spots reaching a lowest temperature of -98° C (-144° F).

“Approximately 100 sites have observed minimum surface temperatures of ~−98 °C during the winters of 2004–2016,” and the researchers believe that this represents close to the absolute coldest the earth’s surface can get.

“This temperature appears to be about as low as it is possible to reach, even under clear skies and very dry conditions, because heat radiating from the cold clear air is nearly equal to the heat radiating from the bitterly cold snow surface,” the report states.

The coldest temperatures were found where pockets of air sat still for several days, allowing it to reach ultra-cold levels.

While Vostok, Antarctica, still holds the world record for the coldest temperature ever measured by a land-based weather station, the scientists hope to deploy ground-based instruments in the coldest locations of the East Antarctic Plateau in the next year or two.

GLOBAL WARMING SMACKDOWN – Arctic Midsummer Freeze

Summer Sea Ice Is Causing Havoc for Shipping in the Arctic
In this July 21, 2017 file photo, broken sea ice emerges from under the hull of the Finnish icebreaker MSV Nordica as it sails through the Victoria Strait while traversing the Arctic’s Northwest Passage. After 24 days at sea and a journey spanning more than 10,000 kilometers (6,214 miles), the …

Summer sea ice is causing havoc for shipping in the Arctic. This is the same Arctic sea ice that climate change experts predicted would have vanished by 2013.

GLOBAL WARMING SMACKDOWN – Arctic Midsummer Freeze

According to the Barents Observer:

It is late June, but the winter has not abandoned the Gulf of Ob. The shallow bay, which houses two of Russia’s biggest Arctic out-shipment terminals for oil and gas, remains packed with fast ice.

It has created a  complicated situation, Rosatomflot says. The state company which manages the Russian nuclear-powered icebreakers, confirms that  independent shipping in the area is «paralysed» and that LNG carriers and tankers are stuck.

Global warming? What global warming?

«The global warming, which there has been so much talk about for such a long time, seems to have receded a little and we are returning to the standards of the 1980s and 1990s,» says company representative Andrey Smirnov.

As the Climatism blog notes, all this summer ice rather contradicts what the “experts” have been telling us for many years.

Meanwhile, in the real world, here is what Arctic sea ice is actually doing. As Steven Goddard says, “party’s over for the Arctic melting scam.”

 June has finished with Arctic sea ice volume fourth highest in the DMI record, behind 2004, 2003 and 2014.

But the big story is the slowdown in melt rates since 2012.  The average June ice loss since 2012 is down 17% relative to the years prior to 2012.

In three weeks, volume melt rates will slow sharply, giving Reggie not much time to make an honest man out of James Hansen.
