Broader look:
The record-setting heat wave that swept through Arctic Siberia in June has yielded a wide-range of deleterious effects in the expansive polar and sub-polar region, triggering raging wildfires, thawing permafrost, and now, spurring the rapid melt-out of Arctic sea ice.
Last month, Siberian temperatures spiked, reaching a record average more than 5 degrees Celsius (9 degrees Fahrenheit) hotter than normal, according to recently released data from the European Union. The remote town of Verkhoyansk in northeast Siberia recorded a reading of more than 38 degrees Celsius (100 degrees Fahrenheit) on June 17, the highest temperature ever recorded north of the Arctic Circle.
Under this metaphorical blow torch, ice extent in the seas that border Siberia has plummeted in recent days, pushing the Arctic region as a whole into the record books. Between July 2 and July 7, sea ice extent across the Arctic Ocean went from being at its fifth lowest extent for this time of year since satellite record-keeping began in 1979, melting into first place, slightly below even the calamitous year of 2012 which eventually saw sea ice hit a record low at the end of the summer melt season in September.
