New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades.
“This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average,” said Dr. Marco Tedesco, Director of the Cryospheric Processes Laboratory at the City College of New York (CCNY – CUNY), who is leading a project studying variables that affect ice sheet melting.
“Melting in 2010 started exceptionally early at the end of April and ended quite late in mid- September.”
The study, with different aspects sponsored by World Wildlife Fund (WWF), the US National Science Foundation (NSF) and NASA, examined surface temperature anomalies over the Greenland ice sheet surface, as well as estimates of surface melting from satellite data, ground observations and models.
In an article published today in Environmental Research Letters, Dr. Tedesco and co-authors note that in 2010, summer temperatures up to 3°C (5.4°F) above the average were combined with reduced snowfall.
The capital of Greenland, Nuuk, had the warmest spring and summer since records began in 1873. Continue reading
