London, Apr 29 (ANI): According to a University of Melbourne, Australia study, melting sea ice has been shown to be a major cause of warming in the Arctic

Published in Nature, the study revealed the rapid melting of sea ice has dramatically increased the levels of warming in the region in the last two decades.

Lead author Dr James Screen of the School of Earth Sciences at the University of Melbourne says the increased Arctic warming was due to a positive feedback between sea ice melting and atmospheric warming.

"The sea ice acts like a shiny lid on the Arctic Ocean. When it is heated, it reflects most of the incoming sunlight back into space. When the sea ice melts,more heat is absorbed by the water. The warmer water then heats the atmosphere above it. "

"What we found is this feedback system has warmed the atmosphere at a faster rate than it would otherwise," he says. (ANI)
