Greenland ice sheet on course to lose ice at fastest rate in 12,000 years, study finds

“By 2100, the ice sheet will shrink to the size it was during the last time the world was hotter than today.”

“The Greenland ice sheet is on track to lose mass at about four times the fastest rate observed over the past 12,000 years. At its current trajectory, such melting would dump huge quantities of freshwater into the sea, raising global sea levels and disrupting ocean currents, scientists concluded in new research Wednesday.

The new findings, published in the journal Nature, warn that the only way to avoid a drastically accelerated meltdown of the massive ice sheet in coming decades is for the global community to curtail emissions of greenhouse gases in the near-term.

Greenland’s ice losses have septupled and are now in line with its highest sea-level scenario, scientists say

Greenland is already the largest contributor to sea level rise, though Antarctica has the potential to increase sea levels even more. As sea levels creep upward, coastal storms including hurricanes and nor’easters become more destructive. Recent trends in more frequent “sunny day flooding” at high tide in places such as Annapolis, Md.; Norfolk; Charleston, S.C.; and Miami is also linked to sea level rise.”
