The North Pole is 36 degrees hotter than it should be right now

Posted in Science on 20th Nov, 2016 12:44 PM by AlexMuller

Temperatures near the North Pole are an unheard of 20°C warmer than average right now, researchers have reported. The Arctic is currently in the midst of polar night, where the Sun hardly ever rises. Usually, it’s the time when things get really cold and thick ice sheets forms for the winter. But this year, temperatures are much warmer than usual:


While the weather stations around the North Pole record the biggest difference, even in parts of Arctic Russia, temperatures are up to 12.6°F (7°C) warmer. And even though sea ice is forming again after reaching its annual low in September, it’s doing so much slower than usual. 

In fact, so far the amount of ice coverage is even lower than the record-breaking low of 2012. "In parts of Arctic Russia, temperatures were 10.8 to 12.6°F [6°C to 7°C] above the long-term average," said Petteri Taalas, the Secretary-General of the World Meteorological Organisation (WMO).
"Many other Arctic and sub-Arctic regions in Russia, Alaska, and northwest Canada were at least 5.4°F [3°C] above average," he added.
"We are used to measuring temperature records in fractions of a degree, and so this is different." This is the second year in a row that temperatures near the North Pole have been unusually high. 
At the end of 2015, the Arctic temperature spiked almost to melting point because of a massive storm pumping warm air into the region. So what’s causing all this unusual variation? Arctic specialist at Rutgers University, Jennifer Francis, told The Washington Post that it’s related to climate change around the rest of the planet – the WMO last week declared that 2016 will most likely be the hottest year on record.
"The Arctic warmth is the result of a combination of record-low sea-ice extent for this time of year, probably very thin ice, and plenty of warm/moist air from lower latitudes being driven northward by a very wavy jet stream," Francis told The Washington Post. 
Meteorologist Richard James, who writes a blog on Alaskan weather, has been tracking 19 weather stations around the Arctic Ocean over the past few months, and has shown that the area has been flooded with warm air since October. 
"So far the lowest daily high temperature this season is 22°F [–5.6°C], which shows a remarkable absence of cold," he writes. 
"The most similar year in the past was 1998, when the coldest day through mid-November had a high temperature of 15°F [–9.5°C]."

We have regularly reports that should make people think how best to address the question of global worming by encouraging global action and agreements - hopefully it is not going to be late..... Reply
