The record-breaking heat in the Arctic saw temperatures soar above 100 degrees for the first time in recorded history. Now, a new analysis has put to rest any notion that the heat was caused by natural temperature fluctuations.
The study found that the record-breaking heat wave was made 600 times more likely by the man-made climate crisis, as The Guardian reported. In other words, the heat wave is nearly impossible without the climate crisis.
The heat in Siberia has produced conditions both strange and awful, with massive wildfires, ravening mosquitoes and shaky permafrost that has caused infrastructure damage, including a burst fuel tank that released about 23,000 tons of diesel fuel into a pristine lake. The wildfires have spread farther north than ever before and have put more greenhouse gases into the earth’s atmosphere than in any other month in 18 years of data collection, according to one report.
To figure out if human actions played a role in the unprecedented heat wave in Siberia, the researchers looked at two recent examples of exceptional heating in the region. The first was a look at the trend line from January through June of this year, when the average temperatures in the region were 9 degrees Fahrenheit hotter than the average temperatures from 1951 to 1980. The second was the remarkable heat on June 20 that saw temperatures at the Russian town of Verkhoyansk at a reported 100.4 degrees, which the Russian Meteorological Service said is a record for temperatures anywhere north of the Arctic Circle, as The New York Times reported.
