Today Greenland ice sheet melts 50% higher than pre-industrial levels and 33% over the 20’s, researchers found.
“What we could show is that the melting experience that Greenland experiences today is truly unrivaled and beyond the charts in the long run,” says Sarah Das, an associate researcher at Woods Hole Oceanographic Institution and a co-author of the study.
To determine how quickly Greenland’s ice recycles compared to the past, researchers used a drill of a traffic light to take ice-core samples.
Samples were taken from locations over 6000 feet above sea level, giving researchers a window to melt on the ice in recent centuries.  A new study shows that Greenland’s ice sheet is [1

Wastewater of October’s urgent report by the United Nations Intergovernmental Panel on Climate Change, warning that civilization has only a decade of to ward off climate disasters, Thursday’s report plays more bad news for the planet, especially the millions of people living near the ocean of the world.
Melting from Greenland ice is the largest single driver of global sea level rise, as scientists predict can sponge coastal towns and settlements in the coming decades.
Eight of the 10 largest cities in the world are close to the coasts and 40% to 50% of the global population live in coastal areas vulnerable to rising seas.
The study also found that Greenland’s ice loss is mainly driven by warmer summer air and that even small temperature hikes can trigger exponential increases in ice melting rates.
“When the atmosphere continues to heat, melting will exceed that warming and continue to accelerate,” said Luke Trusel, a deputy professor at Rowan University, and studying co-authors.
According to Threats, the current thought in the scientific community is that there is a threshold that could lead to a return for possible melting of Greenland and Antarctica icecream. And even though we do not know exactly what this temperature is, it is, after all, the more we heat, the more ice will melt. “
” Once the ice has reached these tip points, it is believed that they will enter a state of irreversible retreat so that they will respond to what we are doing for centuries and milliennia into the future, “said Trusel.  What is because of climate change zero
