Growing Threat to Sea Levels: 'Zombie Ice'

Melting Greenland ice sheet expected to lose 3% of its mass, no matter what

(Newser) - "Zombie ice" from the massive Greenland ice sheet will eventually raise the global sea level by at least 10 inches on its own, according to a study released Monday. Zombie (aka doomed) ice is ice that's still attached to thicker areas of ice but is no longer getting...

That's the sort of flooding in which water invades streets and yards in coastal areas. "Nuisance floods,...

Sea Levels Have Florida Housing Market 'in Distress'

Prices and number of sales are dropping in exposed coastal areas

(Newser) - A 2018 study warned that 64,000 Florida homes were at risk to chronic flooding by 2045 because of rising sea levels. The figure rises to 1 million homes by 2100. Now, new research suggests this effect already is showing up in the state's real estate market, reports NPR...

Greenland Ice: They'll Have to 'Invent New Upper Scenario'

It's melting 7 times faster than it did in the 1990s

(Newser) - Greenland's ice sheet is melting so fast that researchers will have to move the goalposts to estimate the impact on humans in the coming years. That's according to the Ice Sheet Mass Balance Inter-Comparison Exercise, a consortium of nearly 100 polar scientists who reviewed all satellite observations of...

Another SE Asian Nation May Be Moving Its Capital
