The climatologists of the University of Utrecht in the Netherlands predicted the consequences of climate change with greater accuracy, delaying the catastrophic increase in the sea level. According to the new results published in the journal Science Advances, an increase in sea level across a hundred years of about 25 percent lower than expected in accordance with the above-mentioned view of the flooding rate.
The new high-resolution model, refuting the conclusions of the previous studies, takes into account oceanic vortex processes. The whirlwind is a large (10-200 kilometers in diameter) the element of turbulence in circulation, which contributes to the transfer of heat and salt. The addition of oceanic water films into the model leads to a more realistic reconstruction of the temperature of the ocean surrounding Antarctica.
Antarctic ice shield is surrounded by shelf glaciers, which reduce the flow of terrestrial ice into the ocean. Higher temperatures enhance the melting of the shelf glaciers, which helps to accelerate the flow of water in the ocean and, therefore, to an even greater increase in sea level.
The new model predicts a smaller loss of ice mass as a result of the melting of the shelf glacier: only one third compared to the current climatic models. Some regions near Antarctica will even be cooled while global temperatures due to climate change will grow. At the same time, the sea level will continue to rise, but slower, which, in opinion, scientists, can be considered a good news for low sushi sites.
