#ARCTIC. #SIBERIA. THIS IS TAIMYR. Scientists from Russia and the USA have proven that the global warming rate will depend on the diversity of microbes in Arctic latitudes – they are involved in the decomposition of organic matter in thawed permafrost.
The higher the diversity, the slower the climate will change, since for each species the optimal temperature of activity differs, moreover, some species are able to suppress others. The Russian Science Foundation (RSF) reports this. The study was published in the journal Chaos, Solitons & Fractals.
According to Elena Savenkova, a senior researcher at the Center for Scientific Research and Development, Russian scientists and their foreign partners have proven that the moment of a sharp jump in temperature at the surface of the planet depends on microbial diversity. The calculations were carried out using an extended version of the classical model of the Earth’s atmosphere.
Climatologists have added to the model so that it takes into account the activity of microorganisms in the Arctic that feed on organic matter and emit methane. It turned out that the fewer types of microbes are involved in the process, the faster organic matter decomposes – this leads to a sharp release of methane.
Scientists believe that this pattern should be taken into account in modern climate models.
