Zombie ice from Greenland will raise sea level 10 inches

What is the News?

According to a study, zombie ice from the massive Greenland ice sheet will eventually raise the global sea level by at least 10 inches (27 centimeters) on its own.

What is Zombie Ice?

Zombie or doomed ice is ice that is still attached to thicker areas of ice but is no longer getting fed by larger glaciers. That’s because the parent glaciers are getting less replenishing snow.

Without replenishment, the doomed ice is melting from climate change and will inevitably raise the sea level.

What is the significance of this study?

The ten inches rise in global sea level predicted by this study is more than twice as much sea level rise as scientists had previously expected from the melting of Greenland’s ice sheet. 

For instance, the Intergovernmental Panel on Climate Change in its 2021 report projected a range of 2 to 5 inches (6 to 13 centimeters) for likely sea level rise from Greenland ice melt by the year 2100.
