According to Mikhail Naumenko, President of the Lake Discovery Institute Laboratory, these changes are associated with climate fluctuations in the northwest of Russia and affect the ecosystem of the lake. The data obtained will help create more change forecasts.
Since 2013, the average annual temperature in the north of Ladoga Lake has increased by 2 ° C – it reached 4.5 ° C from the beginning of the 20th century, and in the last 30 years, 2020 – 6.5 ° C has become more frequent and hot winters have become more frequent and the hot season has been extended.
This influenced the ice regime: in the last decade, open water sections on the deep parts of the lake began to emerge – for the first time during satellite observations. The smallest ice cover was recorded in the 2020 winter, when the ice covers only 20% of the lake area.
