Antarctica recorded the coldest temperature ever on Earth

Feeling cold ? Here's one consolation: You could be in East Antarctica , the new data says that set a record for the "soul - crushing " cold , from a way of measuring temperature.

Try 135.8 degrees F below zero , that is 93.2 degrees Celsius , which sounds very little toastier . Better yet, do not try. That's what scientists say cold it hurts to breathe.

A new look at NASA satellite data showed that the Earth set a new record for the coldest temperature , as recorded by satellite. It happened in August 2010 when he came to -135.8 degrees. Then on July 31 of this year , approached again : -135.3 degrees.

The previous record , measured by thermometers , is -128.6 degrees, located in Vostok , Antarctica , in 1983.

Scientific Ice Ted Scambos the National Snow Ice Data Center said the new album is " 50 degrees cooler than anything ever seen in Alaska or Siberia or certainly North Dakota. "

" It's more like you would see on Mars in an enjoyable summer at the poles ," said Scambos , of the American Geophysical Union in San Francisco scientific meeting on Monday announced that data . "I am sure that these bags are the coldest places on Earth . "

However, it will not be in the Guinness Book of Records - or recognized by the World Meteorological Organization (WMO ) , the official guardians of the World Weather Records - because the readings were measured by satellites , not thermometers , said Scambos .

"Vostok is still recorded coldest location in the world ," said Randy Cerveny , a professor at Arizona State University , Geography and the rapporteur on climate extremes in WMO. "They are using remote sensing , non-standard weather stations , so that the World Meteorological Organization does not recognize that. "

Regardless of whether or not an official document , it is still incredibly cold : "Thank God , I do not know exactly how you feel ," said Scambos . But she said that scientists routinely make naked 100 degrees below zero outside scripts at the South Pole , so that people can survive that temperature for about three minutes.

Most of the time researchers need to breathe through a tube that brings air into the layer through a sleeve and heats up " so they do not accidentally inhale " , cold air , Scambos said.

On Monday, the coldest temperature U.S. was relatively warm 27 degrees Celsius in Yellowstone , Wyoming, said Jeff Masters, director of meteorology for Weather Underground private firm .

As brand cooler U.S. on record is -80 degrees F , located in Alaska in 1971.

"If you want soul crushing cold , you really have to go abroad ," Scambos said in a telephone interview. "It's just a whole other level because this cold cold plateau , the conditions are perfect. "

Scambos said the air is dry , cold ground, clear skies and cold air swoops down a dome and is trapped at a point less cold " hugging the surface and falls off."

The fact that a point on the Earth has enjoyed record cold that has little to do with global warming, as it is a point in one place , said Waleed Abdalati , ice scientist at the University of Colorado, and former chief scientist at NASA. Both Abdalati , which was not part of the measuring equipment and Scambos said this is probably an unusual random read in a place that has not been measured earlier and could have been colder or warmer in the past and we would not know .

"They talk about the range of conditions on this earth, some of which have not been able to observe ," said Abdalati .
