Scientists predict ice-melting temperatures for Arctic
Some parts of the Arctic will likely witness gusts of warm air over the coming days that will be more than 20C hotter than usual, with some tipping over the 0 degree Celsius melting point of ice, climate scientists have predicted.
This is the second consecutive year for which scientists have predicted ice-melting temperatures for some parts of the Arctic in the middle of winter.
As per the global forecasting system run by the U.S. National Oceanographic & Atmospheric Administration (NOAA), maximum temperatures in parts of the Arctic region will be hotter than the maximum temperatures in most of Canada for the next 5 days.
Climate scientist Andrew King, from Australia’s University of Melbourne, said, “These are very strange temperatures and are getting very close to hitting the freezing point, which is incredible for this time of year. The record November-December temperatures in the Arctic are not seen in the natural world simulations where human influences have been removed.”
Scientists have determined that a low pressure system close to Greenland is pulling warm air towards the Arctic, just like it did last year. A study published earlier this month showed such events, called “midwinter warming”, are now occurring more frequently because of climate change.
Extreme temperatures in the Arctic have thus far been very rare, expected once every 200 years. But by the 2040s, such extreme temperatures are expected to hit the region every second year, on average.
A report published by CBC Canada informed, "On Thursday, the temperature there was almost 30 C warmer than average, and it continued into Friday morning. Ocean buoys recorded temperatures near the North Pole of 0 C or warmer."
"The temperatures there of the atmosphere are on … any given day, like 20 C warmer than they should be for this time of year," Jennifer Francis, a marine and coastal sciences research professor at Rutgers University in New Jersey, told CBC News at the time.
Moreover, last winter was the warmest ever at the North Pole—until this winter, that is. The World Weather Attribution network crunched the peer-reviewed climate models, and concluded that warm years like this one should occur once every 50 years, even in the context of moderate global warming.
