Abstract

According to international climate reports, global warming is not slowing down, and the summer of 2024 will be the hottest on record in the Northern Hemisphere, with an anomalous temperature increase of 0.68°C compared to the 1991-2020 average. The summer of 2024 is particularly marked by an increase in temperature in northern Russia, causing permafrost to thaw. To monitor the response of permafrost to climate change, a monitoring system based on Roshydromet meteorological stations is being established in the Russian Federation, with more than 140 sites planned to be installed by 2025. The monitoring methodology will comply with Russian GOSTs and international standards. The MSU meteorological observatory is also equipped with thermometric boreholes to collect data on ground temperature at the site with natural cover and at the site without natural cover. The results of observations at these thermometric boreholes are compared with mathematical models of the thermal state of the ground at these sites. The results of the observations and mathematical modeling have shown effective methods of analysis and will make it possible to obtain meaningful results on the thermal state of the ground depending on the presence of natural cover.
