Climate change may be rearing its ugly head again in the North Pole, as an Arctic heatwave has caused temperatures to rise tens of degrees Fahrenheit warmer than average.
A report from the Washington Post described how high Arctic temperatures had risen by about 36 degrees Fahrenheit last month, coinciding with record-low sea ice levels. This was a disturbing trend, as sea ice normally expands at this time of the year. But with a buoy recently reporting temperatures at the North Pole close to the freezing point of 32 degrees Fahrenheit, talk of an Arctic heatwave has experts concerned about the impact of climate change on the area.
Speaking to the BBC, Oxford Environmental Change Institute senior researcher Friederike Otto said that such spikes in temperature would have been "extremely rare" before the industrial age, perhaps occurring every thousand years or so. As such, she and her fellow researchers believe that the temperature spikes in the Arctic are related to man-made climate change.
"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."
