Siberia is one of the coldest regions on Earth, but is currently facing intense fires and high temperatures.
The region’s carbon dioxide emissions in June were the highest in 18 years of the CAMS data set, breaking a record of 53 giants in June 2019.
“The higher temperatures and drier surface conditions provide ideal conditions for these fires to burn and remain for such a long time in such a large area,” said CAMS Senior Scientist Mark Parrington.
“We have seen very similar patterns in fire activity and soil moisture irregularities throughout the area in fire monitoring activities in recent years.”
Temperatures in the region were up to 10 degrees Celsius (18 degrees Fahrenheit) higher than the average in June.
Siberia tends to show large changes in temperature from month to month and from year to year. However, temperatures in the area have remained well above average since 2019, which is unusual.
June temperatures across Siberia were above five degrees Celsius (nine degrees Fahrenheit) higher than average and more than one degree Celsius (1.8 degrees Fahrenheit) higher than the same month in 2018 and 2019, both previous warmer June.
But not all parts of the area have been affected. Western Siberia recorded mostly below-average temperatures last month.
The entire planet saw the highest temperatures last month, compared to 2019 for the warmest June, at 0.53 degrees Celsius (0.95 degrees Fahrenheit) above the 1981-2010 average.
In 2020, Copernicus found that four of the first six months of the year were either the hottest in the world or were linked to previous record temperatures. The exceptions were February and March 2020, which were the second warmest in the world.
“Finding what caused these record temperatures is not a simple endeavor, as there are many factors that interact with each other. Siberia and the Arctic Circle generally have large variations from year to year and have experienced other relatively warm Junes before,” he said. C3S director Carlo Buontebo. “What’s worrying is that the Arctic is heating up faster than the rest of the world.”
The Arctic is heating up twice as fast as the rest of the planet through a process known as Arctic amplification.
Arctic ice has accelerated, leading to seasonal snow cover that is less white and absorbing more sunlight, which leads to more heating, according to the National Oceanic and Atmospheric Administration (NOAA).
CS3 researchers believe that large-scale wind patterns in Siberia and low snow cover and surface soil moisture may have led to mild temperatures there in the spring.
