Central Asia is increasingly turning into a desert due to climate change. What is the study Published in the scientific journal Geophysical Research Letterswhich developed an assessment of the climate in the region, focusing on countries such as Kazakhstan, Kyrgyzstan, Uzbekistan, Turkmenistan and Tajikistan, as well as the northern part of China.
The researchers analyzed climate types according to several variables namely temperature, precipitation and seasonality, and distinguished them with BS models; BW, Cf, Do, Dc, Ft, Fi. The evaluation period was between 1960 and 2020.
Since 1980 until today, it has been possible to notice an expansion of the desert climate to the north by more than 100 km and a successive increase in temperatures in all climates. In mountainous regions, for example, a warmer and wetter climate began to exist, moving from a cold to a northern one. They said changes in climate types began to alternate more frequently from 1990 onwards. In some locations, between 1990 and 2020, the average annual temperature rose by at least 5°C compared to the time period between 1960 and 1979.
This situation begins to alter plant and animal life and the functioning of the ecosystems of each of these regions, and may cause soil degradation and affect its productivity. As author Jeffrey Dukes adds in the magazine, temper nature“This would have consequences for things like grazing animals that depend on the steppes or grasslands.“.
