In Siberia, however, it was not only May that was warmer than normal – the region experienced higher surface air temperatures than average during winter and spring, especially warmer temperatures since January.
“It is undoubtedly an alarming sign,” said a senior C3S scientist Freja Vamborg. Said.
C3S said Siberia tends to see month-to-month and year-on-year large temperature changes, and months have passed since temperature abnormalities are greater than the region has experienced in the last six months. However, according to C3S, it is unusual to see warmer temperatures than average for many consecutive months.
Despite the warming of the Earth as a whole, temperature spikes do not occur evenly across the planet, Vamborg said.
He said that Western Siberia stands out as a region with a warming trend with higher temperature variations.
The effects of higher temperatures
Higher temperatures seem to already have negative effects.
The energy company parent, Nornickel, said the establishment of the storage tank was likely to sink due to the dissolution of the permafrost and highlight the dangers caused by the increasing temperatures in the Arctic infrastructure and ecosystems, according to the Russian state news agency TASS.
“Right now … because of the abnormally warm summer temperatures recorded in the past years, we can assume that permafrost may melt and the pillars under the platform may have sunk,” said NASSickel operations manager Sergey Dyachenko, according to TASS.
Sergey Verkhovets, coordinator of Arctic projects for Russia’s WWF branch, said the incident ended in disaster.
“We will see the reflections for years to come,” Verkhovets said. Said. “We’re talking about dead fish, dirty feathers of birds and poisonous animals.”
