A researcher from MIPT has proposed a new explanation for the Arctic?s rapid warming. In his recent paper inGeosciences, he suggests that the warming could have been triggered by a series of great earthquakes.

Global warming is one of the pressing issues faced by civilization. It is widely believed to be caused by human activity, which increases the concentration of greenhouse gases in the atmosphere. However, this view does not explain why temperatures sometimes rise fairly abruptly.

In the Arctic, one of the factors driving climate warming is the release of methane from permafrost and metastable gas hydrates in the shelf zone. Since researchers began to monitor temperatures in the Arctic, the region has seen two periods of abrupt warming:…

Despite sea level rise, a 2019 global analysis (Duvat, 2019) found 89% of 709 island coasts have been either stable or growing in size in recent decades. A new Maldives-only study (Duvat, 2020) finds rapid (>3 to >50%) coastal growth in 110 of 186 Maldives islands from 2005 to 2016. Just 5 islands ? 2.7% ? actually contracted in size during this period.

Last yearDr. Virginie Duvatpublished aglobal assessmentof how the Earth?s islands and atolls are faring against the ongoing challenge of sea level rise since satellite monitoring began in the 1980s.

Fortunately she found ?no widespread sign of physical destabilization in the face of sea-level rise.? In fact, a) none of the 30 atolls analyzed lost land area, b) 88.6% of the 709 islands studied were either stable or increased in area…
