Sanctions to Blame: Global Climate Models Stop Working Without Data from Russia

Climate models, which have been compiled in the West since 2022 without taking into account data from Russia, are a waste of time because they are unreliable. This was stated by participants in the INTERACT research project, climatologists from Denmark, Finland, Great Britain and the USA.

How climate models work

A climate model, which helps to judge climate change, is compiled on the basis of data from all over the globe. They are included in a digital model for forecasting. Indicators of the atmosphere, hydrosphere, land, soil cover, and glaciers are taken into account. With the help of complex mathematical calculations, changes are calculated in certain time intervals.

Arctic Monitoring

The Arctic is called the "weather kitchen" of the Earth. Cyclones are formed here, melted ice feeds the Atlantic, and ice cover cools the entire planet. The accuracy of data for climate models depends on understanding the processes that occur in the Arctic region. These issues are also dealt with by the Arctic Council, an international forum promoting cooperation in the Arctic. Since 2023, Russia has not been invited to council events.

Today, there is not a single joint international project in the Arctic with the participation of universities or scientific organizations from Russia

She explained that 21 of the 95 ground stations of the INTERACT project are located in Russia. Against the background of sanctions, Western scientists do not receive data from the Russian side.

On the right is the deviation in the reliability of the parameter, taking into account data from Russian stations (gray) or without them (red). The dark gray bar is the maximum deviation of modern parameter values compared to the values of the end of the last century (with confidence intervals). The parameter estimate is considered reliable if the deviation value is below this bar

In fact, INTERACT is doing useless work. Their unreliable conclusions are used by specialists from the World Meteorological Organization, the International Council for Science and other departments. Climatologists from Denmark, Finland, Great Britain and the USA, involved in INTERACT, emphasized that the international scientific community should create monitoring programs that are representative of the entire Arctic, and this cannot be done without exchanging data with all countries, including Russia.

Roscosmos receives information about the situation in the Arctic from the new Arktika-M No. 2 hydrometeorological satellite, launched into space in mid-December 2023.
