Experts predict that sea level could rise by 100 cm by 2100.
The Intergovernmental Panel on Climate Change (IPCC) has published a special report on the Ocean and Cryosphere in a Changing Climate. According to the authors’ findings, sea level could rise by 100 cm by 2100.
Previously, scientists used to consider St. Petersburg a risk zone. However, one of the authors of the IPCC’s special report, Alexey Yekaikin, Leading Researcher with the Arctic and Antarctic Research Institute, thinks that St. Petersburg is not going sink. He told RIA Novosti that the earth under the city is rising.
People tend to believe the Earth is ball-shaped. If we pour water over a ball, the water level should be rising evenly, but that is not so. The shape of the Earth is not an ideal sphere, moreover, it is changing, there are vertical movements in the Earth’s crust. Venice is a classic example. The earth is going down in that region. <…> On the other hand, there is St. Petersburg, where the earth is rising slightly, RIA Novosti quotes the expert as saying. This leads him to a conclusion that St. Petersburg is out of the risk zone.
