Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics

During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe. These sudden episodes, called Heinrich Events, occurred between 16,000…

‘Disastrous’ melting of Greenland, Antarctic ice sheets moves into hyperdrive Greenland

‘Disastrous’ melting of Greenland, Antarctic ice sheets moves into hyperdrive

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different satellite estimates, researchers found that Greenland’s melt has gone into hyperdrive in the last few years.…
