Modern geological studies reveal an extremely risky mechanism related to climate transformations in West Antarctica. Experts warn of a possible activation of over a hundred hidden volcanic zones under the thick ice cover.

When massive ice layers decrease, the geological pressure on underground magma chambers changes. This process can trigger a chain of explosive volcanic eruptions with potentially unpredictable consequences.

Parallels with similar phenomena have already been documented in Iceland, where glacier retreat has historically provoked volcanic activity. However, the Antarctic region is considered significantly more risky due to the specifics of its sub-ice geological structures.

The scientific team warns that potential volcanic eruptions would generate additional greenhouse emissions, which would further accelerate global climate changes. As a preventive measure, experts insist on installing specialized sub-ice sensors and in-depth integration of geological data into existing climate models.

The study underscores the critical need for comprehensive monitoring and precise forecasting of potential geological transformations in one of the planet's most sensitive regions.
