German researchers revealed that Greenland ice It is 1.5°C warmer than the last thousand years, which is a product of global warming.
To find out, it was reconstructed by experts from the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research (AWI). Temperature of the nucleus of ice for the last thousand years. In particular, look at the last decade, 2001-2011, which was the warmest in a thousand years.
To do this, they used a set of nuclei of ice Unprecedented in length and quality, reconstructed Temperature passes through the mid-north Greenland and the rate of ice sheet melting.
“The time series that we retrieved from the core ice It now covers over 1,000 consecutive years from 1000 to 2011. These data show that temperatures between 2001 and 2011 are clearly distinct from natural variations over the past thousand years. Although critically expected in light of global warming, we were surprised how pronounced this difference actually was,” said the study’s lead author, AWI glaciologist Dr. Maria Horhold said.
moreover Temperature, The team rebuilt the production of ice cap melting, informing that melting has increased significantly Greenland Contributes significantly to global sea level rise since the 2000s and now.
The results of the study were published in the specialized journal Nature.
Greenland and its importance in the Earth’s climate system
layer of Greenland ice plays a fundamental role in global climate system. because melting And sea-level rise as a result of the massive amount of water stored in the ice, about 3 million cubic kilometers, is thought to be a potential tipping point.
In fact, the ice sheet is projected to contribute up to 50 centimeters to global mean sea level rise by 2100.
