A record-breaking heatwave in Siberia would have been almost impossible without human-caused climate change, a study has found.
The Russian region’s temperatures were more than five degrees Celsius above average between January and June of this year.
Temperatures exceeded 38 degrees Celsius in a Russian town north of the Arctic circle on June 20, the highest temperature ever recorded. The Arctic is believed to be warming twice as fast as the global average.
An international team of climate scientists found the record average temperatures were likely to happen less than once every 80,000 years without human-induced climate change. That makes such an event “almost impossible” had the world not been warmed by greenhouse gas emissions, they conclude in the study.
In a news release, the scientists describe the finding as “unequivocal evidence of the impact of climate change on the planet.”
