North Pole may see record-breaking heatwave this Christmas Eve
Climate scientists have predicted that the North Pole will likely witness a record-breaking heatwave this Christmas Eve, with temperatures in the region estimated to be up to 20 degrees higher than average.
Using satellite data, scientists estimated that temperatures throughout the months of November and December were significantly higher than average. It followed a hotter summer during which Arctic sea ice contracted to the second-lowest extent ever recorded.
Dr. Friederike Otto, a senior researcher at the Environmental Change Institute at Oxford University, said a heatwave like it would have been extremely rare in preindustrial era as they would expect it to occur only once in around 1,000 years.
She warned that the rare weather patterns were the result of anthropogenic climate change. In other words, scientists once again blamed manmade carbon emissions for the problem.
Speaking on the topic, she said, “We have used several different climate modelling approaches and observations. And in all our methods, we find the same thing; we cannot model a heatwave like this without the anthropogenic signal.”
The scientist have also predicted that the warm air from the North Atlantic region will flow all the way to the North Pole via Spitsbergen, which would give rise to clouds that would prevent heat from escaping.
"Such spikes in Arctic temperatures are becoming more frequent because we have a declining sea ice cover - the water below is warmer,” said Jesper Eriksen, a forecaster at the Danish Meteorological Institute.
A report published by Irish Times said, "The Arctic region is warming at twice the global average, disrupting the hunting livelihoods of indigenous people and threatening creatures such as polar bears while opening the region to more shipping and exploration for oil and gas."
"These pronounced changes in vegetation led in a substantial increase in albedo across the growing season. Our modelling results showed this increase in albedo would result in a corresponding decrease in net radiation and latent and sensible heat fluxes - indicating that heavily grazed sites absorbed less radiation," a report published in Express UK informed.
Climate Central, an independent organisation of scientists and science commentators, explained how experts have been looking at the way temperatures in the Arctic region have been high to see if climate change is a factor.
