The warming climate in polar regions may significantly disrupt ocean circulation patterns, a new study published today in Nature Communications indicates.
The warming climate in polar regions may significantly disrupt ocean circulation patterns, a new study published today in Nature Communications indicates.
Scientists discovered that in the distant past, growing inflows of freshwater from melting Arctic sea-ice into the Nordic Seas likely significantly affected ocean circulation, sending temperatures plummeting across northern Europe.
“Our finding that enhanced melting of Arctic sea-ice likely resulted in significant cooling in northern Europe in the earth’s past is alarming,” says Mohamed Ezat from the iC3 Polar Research Hub, lead author of the new study.
“This reminds us that the planet’s climate is a delicate balance, easily disrupted by changes in temperature and ice cover.”
