Climate change will increase the Siberian heatwave by 600 times - study



According to one study, the heatwave in the Siberian Arctic is at least 600 times higher than man-made climate change.


Between January and June, temperatures in the north of Russia average above 5C, causing permanent frost to melt, buildings to collapse and an unusually early and intense start to the wildfire season. On June 20, a monitoring station in Varkhoyansk recorded a record 38C.

A characteristic study suggests that such prolonged heat in the first six months of the year is virtually impossible without the impact of greenhouse gas emissions from industry, transportation, and agriculture.

This human impact, calculated by a team of researchers from international universities and meteorological services, including the PP Shirshov Institute of Oceanography at the Russian Academy of Sciences, added at least 2C warming to the region.

The authors of the study say that Siberian heat occurs once every 80,000 years without human intervention.

Andrew Civerella, senior author and senior investigator and attribution scientist at the Met Office, said the results were shocking. "This research is another proof of extreme temperatures, which we can expect to see more in warmer global climates around the world. In particular, we can control the increasing frequency frequency of these extreme thermal events by reducing greenhouse gas emissions."

Scientists say human fingerprints are rarely clear. "This is the biggest sign we've seen," said Frederick Otto, acting director of the Oxford Institute for Environmental Change and co-leader of the World Weather Attribution Initiative. "This study shows how much game-changing climate change is related to heatwaves. As emissions continue to rise, we need to think about creating resilience to extreme heat around the world - even in Arctic societies - which did not seem meaningless long ago. "

On May 29, from a power plant near the industrial city of Norilsk, one of Russia's worst oil spills required strong flexibility in melting permit frost and improperly maintained equipment.

Olga Zolina, a professor at the Institute of Oceanography in Moscow, and another leading author say that Norilsk's fate may be a sign of the lies inherent in other northern societies. "That means we have to do something. The city is very small with about 1,000 inhabitants. But there are other big cities in the Arctic Circle. Rising high temperatures are very important to them."

Concerns are growing that high temperatures in Siberia, home to the world's largest forest, are exacerbating positive response loops by melting heat-reflecting ice and increasing the spread of wildfires.

The fire of the season began abnormally in April and was revealed in the north more than ever before. According to the European Union's Copernicus satellite monitoring service, the Siberian explosions released 59 megatons of carbon dioxide in June, the highest level ever.

NASA says some of the coal in the peatland will smoke in the winter and come back to life in the spring. The dangers of such "zombie fires" are exacerbated by warmer temperatures. Melting the tundra also increases the risk of the release of methane, a highly potent greenhouse gas. Since mid-June, fire spread has more than doubled to more than a million hectares.
