Arctic Temperatures 45 Degrees Above Normal Recorded

Another warning about the threat of climate change.

While the Eastern United States simmered in some of its warmest February weather ever recorded Tuesday and Wednesday, the Arctic is also stewing in temperatures more than 45 degrees above normal. This latest huge temperature spike in the Arctic is another striking indicator of its rapidly transforming climate.

On Monday and Tuesday, the northernmost weather station in the world, Cape Morris Jesup at the northern tip of Greenland, experienced more than 24 hours of temperatures above freezing according to the Danish Meteorological Institute.

“How weird is that?” tweeted Robert Rohde, a physicist and lead scientist at Berkeley Earth, a non-profit organization that conducts analyses of the Earth’s temperature. “Well it’s Arctic winter. The sun set in October and won’t be seen again until March. Perpetual night, but still above freezing.”

The Danish Meteorological Institute wrote that only twice before had it measured temperatures this high during February at this location, in 2011 and 2017. It is a mere 400 miles from the North Pole.

An analysis from Climate Central said these extreme winter warming events in the Arctic, once rare, could become commonplace if the planet continues warming. A study in the journal Nature published in 2016 found the decline of sea ice in the Arctic “is making it easier for weather systems to transport this heat polewards.”

Arctic sea ice was at its lowest extent on record this past January, according to the National Oceanic and Atmospheric Administration.

Permafrost in the Arctic is Thawing Faster Than Ever

Another reminder that humans need to seriously address climate change.

Permafrost in the Arctic is thawing faster than ever, according to a new US government report that also found Arctic seawater is warming and sea ice is melting at the fastest pace in 1,500 years.

The annual report released on Tuesday by the National Oceanic and Atmospheric Administration showed slightly less warming in many measurements than a record hot 2016. But scientists remain concerned because the far northern region is warming twice as fast as the rest of the globe and has reached a level of warming that’s unprecedented in modern times.

“2017 continued to show us we are on this deepening trend where the Arctic is a very different place than it was even a decade ago,” said Jeremy Mathis, head of NOAA’s Arctic research program and co-author of the 93-page report.

Findings were discussed at the American Geophysical Union meeting in New Orleans.

“What happens in the Arctic doesn’t stay in the Arctic; it affects the rest of the planet,” said acting NOAA chief Timothy Gallaudet. “The Arctic has huge influence on the world at large.”

Permafrost records show the frozen ground that many buildings, roads and pipelines are built on reached record warm temperatures last year nearing and sometimes exceeding the thawing point. That could make them vulnerable when the ground melts and shifts, the report said. Unlike other readings, permafrost data tend to lag a year.

Preliminary reports from the US and Canada in 2017 showed permafrost temperatures are “again the warmest for all sites” measured in North America, said study co-author Vladimir Romanovsky, a professor at the University of Alaska in Fairbanks.

Arctic sea ice usually shrinks in September and this year it was only the eighth lowest on record for the melting season. But scientists said they were most concerned about what happens in the winter – especially March – when sea ice is supposed to be building to its highest levels.

Arctic winter sea ice maximum levels in 2017 were the smallest they’ve ever been for the season when ice normally grows. It was the third straight year of record low winter sea ice recovery. Records go back to 1979.

About 79% of the Arctic sea ice is thin and only a year old. In 1985, 45% of the sea ice in the Arctic was thick, older ice, said NOAA Arctic scientist Emily Osborne.

New research looking into the Arctic’s past using ice cores, fossils, corals and shells as stand-ins for temperature measurements show that Arctic ocean temperatures are rising and sea ice levels are falling at rates not seen in the 1,500 years. And those dramatic changes coincide with the large increase in carbon dioxide levels in the air, the report said.

This isn’t just a concern for the few people who live north of the Arctic circle. Changes in the Arctic can alter fish supply. And more ice-free Arctic summers can lead to countries competing to exploit new areas for resources. Research also shows changes in Arctic sea ice and temperature can alter the jet stream, which is a major factor in US weather.

This is probably partly responsible for the current unusual weather in the United States that brought destructive wildfires to California and a sharp cold snap to the south and east, according to NOAA scientist James Overland and private meteorologist expert Judah Cohen.

“The Arctic has traditionally been the refrigerator to the planet, but the door of the refrigerator has been left open,” Mathis said.

Outside scientists praised the report card.

“Overall, the new data fit with the long-term trends, showing the clear evidence of warming causing major changes,” in the Arctic, said Pennsylvania State University ice scientist Richard Alley.
