The size of the latest greenland melting is “exceptional” compared with historical data in the past 350 years, according to a new study by a research team from the United States and the Netherlands.
Background: ] In terms of greenland and sea level rise, the basics are well-known – the temperature of the air increases, causing the ice to melt from above. The water percolates down through the ice and eventually flows into the ocean, where it adds to sea level. At the same time, the glaciers accelerate their flow into the ocean as heating of ocean temperatures eats away from them below.
Yes, but: The big question is – to what extent is the surface of the summer surface melted unusual?
Why it matters: Refining the rise in sea level would help researchers predict how much damage can be expected in the coastal areas of the world. It would also help them to determine what to expect from a slowdown in a crucial ocean stream that draws heat north of the equator, changes ecosystems and weather patterns.
What They Did: The researchers collected and analyzed ice cores from Central Western Greenland and a coastal area on the Nuussuaq Peninsula in 2015.
What They Found: In the last decades there was a clear wars of war d more melting, watercooling through ice and refreezing every winter.
“As a result, Greenland is more sensitive to temperature change today than a few decades ago. Heating is more than ever.”
Bottom line: “This is a climate record that you can easily add together with a story book – clear to see [the] human fingerprints on Greenland’s Ice Sheet, “says Robin Bell, a research professor at the Lamont-Doherty Earth Observatory at Columbia University, at Axios. Bell was not involved in the study.
