Scientists have predicted when the Arctic completely melts: disaster is near

Ученые спрогнозировали, когда Арктика полностью растает: катастрофа уже близко

Experts around the world have repeatedly sounded the alarm about the fact that because of climate change in the Arctic began to melt perennial glaciers. Global warming may lead to the fact that this process will go faster, which will increase Global sea level and the destruction of civilization.

Scientists explain that understanding how fast is the melting of glaciers is very important to take timely action to prevent disaster. As reported in the article of the journal Nature Climate Change, glaciers in the Arctic ocean is melting much faster than previously assumed. Over the last 40 years the temperature rose much higher than it was inherent in the forecasts. About this newspaper writes “Facts”.

“Interglacial, a warmer period 116-130 thousand years ago, is a potential analogue of future climate change. Summer insolation of the period at high Northern latitudes has led to the fact that temperatures on land in the Arctic have become four or five degrees higher than in pre-industrial times. Climate modeling had not previously been able to catch these elevated temperatures – perhaps because they were not able to correctly identify changes in sea ice. We show that the latest version of the climate model of Hadley Centre, UK (HadGEM3) reflects a more accurate prediction of the climate during the Mikulinsky interglacial, including elevated temperatures,” – said the scientists.

They note that underestimated the rate of temperature rise in the atmosphere closest to the sea level. And this, according to Professor Jens Christensen of Heidelberg, led to the disappearance of sea ice much faster than expected. In addition, the modeling of what awaits us in the future, based on the Mikulinsky interglacial period shows that the Arctic may entirely lose its sea ice by 2035.

The Professor added that the current speed is yet to be assessed and the significance and consequences of sharp rise in temperature.

“Changes are happening so quickly in the summer months. Sea ice is likely to disappear faster than predicted by most climate models. We must continue to closely monitor temperature changes and to take into account in these models, the correct climate processes,” he said.
