Sea level likely to rise by 2 metres for each degree of global warming

July 15th, 2013 by Potsdam Institute for Climate Impact Research

Greenhouse gases emitted today will cause sea level to rise for centuries to come. The paper “The multimillennial sea-level commitment of global warming” published in the Proceedings of the National Academy of Sciences shows that each degree of global warming is likely to raise sea level by more than two meters in the future. While […]

Current atmospheric C02 level must be reduced to protect coastal cities

January 3rd, 2013 by National Oceanography Centre

By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present of nearly 400 parts per million (ppm) were systematically associated with sea levels at least nine metres above current levels. The […]
