Greenland temperatures have risen to a current peak of 1.5°C warmer than the 1900s average, the warmest decade in 1,000 years. According to the data acquired from the study of ice cores, a drama has been going on since 1995: this is what emerges from a study by the German Alfred Wegener Institute for Marine and Polar Research which describes the data emerging from ice cores.
The change in the composition of the ice is such compared to pre-industrial times that the possibility that it is something not related to man is impossible.
Furthermore, if the air over Greenland gets too warm it could trigger a difficult situation to deal with.
And melting the ice cap would bring it to a lower altitude, which would expose it to warmest and warmest air, eventually eventually collapsing. Maria Hörhold, lead author of the study and a scientist at the Alfred Wegener Institute in Bremerhaven, Germany, said: "The decade 2001-2011 was the warmest in 1,000 years."
Greenland near collapse: the last decade the warmest in 1,000 years
Isabella Velicogna, a professor at California University, who explains that studies have shown an unprecedented increase in temperatures: "This doesn't change what we already knew about Greenland warming, but it adds momentum to the gravity of the situation.
And this is bad news." In addition, the study, published in the journal Nature, found that the coldest part of the Greenland ice sheet was 1.5 degrees warmer than last century as a whole, and that the rate of melt and water loss from the glacier have increased significantly, leading to significant sea level rise.
The researchers explain that the youngest ice contained in these cores dates back to 1995, and that this has not allowed us to fully investigate the temperatures that are currently recorded. Scholars, thanks to the analysis of the temperatures detected in the ice caps drilled in the two-year period 2011-2012 and those detected in older ice caps, were able to propose a comparison between the temperatures of over a millennium ago and those of the last decade.
Jason Box, a researcher at the Geological Survey of Denmark and Greenland, said: "We should be concerned about warming in the northern part of the glacier because there is a risk of significant sea level rise."
