#ARCTIC. #SIBERIA. THIS IS TAIMYR. Scientists from the Vernadsky Institute of Geochemistry and Analytical Chemistry have discovered that climate change is stimulating the growth of harmful vegetation in Arctic lakes. According to the researchers, the increase in phytoplankton is caused by an increase in the phosphorus, nitrogen, and organic matter concentration in the air and water. At the same time, water bodies that are not directly affected by humans were studied. This was reported by TASS with reference to the Russian Ministry of Education and Science.
“With global warming, another biogenic element, silicon, is also involved in the biogeochemical cycle as a result of its absorption by intensively developing diatoms”, the report says.
Scientists have summarized data on more than a hundred water bodies, which were studied every five years from 1990 to 2023 as part of the international ICP-Water program. The water condition was assessed based on such parameters as transparency, total phosphorus, phosphates and chlorophyll A.
The researchers concluded that in 2010–2018, the number of lakes with high water transparency, low organic matter, phosphorus and nitrogen content and, as a result, low bioproductivity in the tundra zone decreased by 30 percent compared to the period 1990–2000. And in the northern taiga zone, there are almost no such lakes left.
Earlier, scientists concluded that warming in Taimyr is happening very quickly. Climate change will reduce global fish stocks and also lead to freezing rains and floods in the Arctic.
