Greenland ice cap loses enough water in 20 years to cover US: study

COPENHAGEN, Denmark (AFP) – Greenland’s immense ice sheet has lost enough ice in the past 20 years to submerge the entire United States in half a metre of water, according to data released this week by Danish researchers. The climate is warming faster in the Arctic than anywhere else on the planet and melting ice from Greenland is now the main factor in the rise in the Earth’s oceans, according to NASA. Since measurements began […]

Extreme Greenland ice melt raised global flood risk: study

by Patrick GALEY Agence France-Presse PARIS, France (AFP) – The 3.5 trillion tonnes of Greenland’s ice sheet that has melted over the past decade has raised global sea levels by one centimetre and is heightening worldwide flood risks, new research showed on Monday. The ice sheet atop the world’s largest island contains enough frozen water to lift oceans some six metres (20 feet) globally, and extreme melting events there have been increasing in frequency for […]

Earth’s ice sheets tracking worst-case climate scenarios

by Marlowe HOOD PARIS, France (AFP) — The Greenland and Antarctic ice sheets, which hold enough frozen water to lift oceans 65 metres, are tracking the UN’s worst-case scenarios for sea level rise, researchers said Monday, highlighting flaws in current climate change models. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change’s (IPCC) most extreme forecasts, which see the two ice sheets […]

Eurasian ice sheet collapse raised seas eight meters: study

by Patrick GALEY Agence France Presse PARIS, France (AFP) — The melting of the Eurasian ice sheet around 14,000 years ago lifted global sea levels by about eight meters, according to new research published Monday that highlights the risks of today’s rapid ice cap melt. Earth’s last Glacial Maximum period began around 33,000 years ago, when vast ice sheets covered much of the Northern Hemisphere. At the time, the Eurasian ice sheet — which covered […]
