Yesterdays act of terrorism when Ukraine blew up the Kahovskaja HPP dam creates not only a military and humanitarian difficulty for Russia, not only does it create a short-term ecological disaster, killing hundreds of thousands of animals in one swipe, not only does it create a mid-term epidemiological disaster, when ll that has been washed off begins to rot and decompose, it also exacerbates a long-term looming catastrophe hanging over the Black Sea. As it stands now, the sea is already on the verge of going up in a hige fireball, and any additional dumps of the sediments and warm water only hasten that outcome.
Below is a translation of an article by “Argumenty i Fakty” from the 29th of May 2023.
Turkish geologist, Professor Osman Bektash warned about the impending danger to all who live on the Black Sea coast. According to him, global climate change is to blame.
The middle layer is thinning
Insufficient precipitation and an increase in temperatures above average values have led to the fact that life in the depths of this sea has become impoverished. The number of fish has decreased, the diversity of biological species has decreased. But that’s not even the main concern.
The Black Sea is practically a closed basin, it is connected to the World Ocean through the narrow Bosphorus Strait. The rivers flowing into it — the Dnieper, Dniester, and Danube — have deposited silt over millions of years, which settled on the bottom and produced hydrogen sulfide as a result of chemical reactions. The excess of this gas with a foul smell of rotten eggs in the depths is the most famous and unusual feature of the Black Sea. It accumulated there for a long time, and since its solution is heavier than water, hydrogen sulfide concentrated in the deepest places.
