Soil samples "told" scientists what the climate was like 50,000 years ago

It turns out that the current global warming is far from the first. Just like now, in the area of ​​the Taz River, which flows through the territory of the Yamalo-Nenets Autonomous Okrug (Yamalo-Nenets Autonomous Okrug), it was warm about 115 thousand years ago, and 100 thousand years later, permafrost has already formed here.

Such conclusions were reached by an international scientific expedition, which included scientists from Russia (Tyumen Industrial University), Mexico, Israel and Poland as a result of studies of soil samples on the territory of the Yamalo-Nenets Autonomous Okrug in the Nadym and Taz regions within the framework of a project to develop the Russian Arctic zone.

In addition to Russia, the collected samples will then be sent to research institutes in Mexico and Poland. They will enable scientists to reconstruct the picture of the climate 45 thousand years ago and create the necessary basis for predictions for the future. In particular, they will help to predict the consequences of the beginning of global warming.

In the course of research, scientists also revealed that the underwater Gakkel ridge located at the bottom of the Arctic Ocean quite quickly - about 3-4 mm per year - "creeps" into Western Siberia, creating there high seismic activity, which will have to be taken into account when constructing facilities.
