The ice sheets of Greenland and Antarctica worry the scientists, because their condition is extremely close to critical. The glaciers contain a huge volume of water that can raise the level of the world ocean by 65 meters. The researchers are watching the situation, but today they admit that the worst predictions begun to come true.
The period from 2007 to 2017 was accompanied by a loss of mass of glaciers, and it almost completely coincided with the most extreme forecasts of the Intergovernmental Panel on Climate Change (IPCC).
The experts assumed that with that development of events, the planet's two ice sheets will increase the volume of the world's oceans by 40 centimeters by 2100. And if it happens, the most devastating consequences will ensue.
The destructive force of storm surges will increase, and coastal areas that are inhabited by millions of people will be prone to repeated and severe flooding. In 2014, the IPCC prepared another report with a forecast: the world ocean level is expected to rise by 70 centimeters from all sources, including mountain glaciers, and an increase in the volume of ocean water as it warms up.
Despite the inconsistency between the forecasts and the reality that tracks these trends, last year the experts' report said support for previous forecasts regarding the state of Greenland. It also mentioned a small increase in water volumes from Antarctica under the scenario of the highest greenhouse gas emissions.
Thomas Slater, a researcher from the Center for Polar Observation and Modeling, believes the time has come to develop a new, worst-case scenario of predicted ice sheet events. It is necessary because the rate of ice melting has increased significantly.
Such projections are essential for governments around the world to create climate policies and strategies for future mitigation and adaptation.
