London: Record-breaking heat in Siberia during the first half of this year would be nearly impossible without the effects of human-induced climate change, according to a new study.
High temperatures in northern Russia have triggered massive wildfires, worrying about the potential impact on the global climate of rapid changes in the Arctic, destroying normally moist peat bogs and melting permafrost .
Modeling by an international team of scientists, if greenhouse gas emissions had not warmed Earth’s climate 1 degree Celsius more often than before, it would heat once every 80,000 years.
“The findings of this rapid research have said that climate change has increased the likelihood of prolonged warming in Siberia by at least 600 times,” said Andrew Siavarella, the lead author of the research and senior scientist at the UK Met Office.
A new record temperature for the Arctic, 38C (100.4 ° F), was recorded on 20 June in the city of Verkhoysk, while the total temperature in Siberia was above 5C on average from January to June.
In May, an oil tank built on frozen soil collapsed, causing the worst oil spill in the area.
Researchers said the heat has extinguished more than the annual emissions of about 56 million tons of carbon dioxide – such as Switzerland and Norway – with 1.15 million hectares burning at the end of June.
“We are continuing to study how wildfires spread over thousands of hectares can also affect the climate as flames and smoke pump in flames,” Olga, co-author of PP Shirov Institute of Oceanology in Russian Said Zolina. Academy of Sciences in Moscow.
Even in the current climate, the heat observed in Siberia would only be expected to be less than once in 130 years, the researchers said. But he warned that such incidents could be common in Siberia by 2100 without rapid reductions in emissions.
