Datasets and protocols for including anomalous freshwater from melting ice sheets in climate simulations
Abstract. Anomalous freshwater fluxes from the Greenland and Antarctic ice sheets and ice shelves are impacting the surrounding oceans, and we need to be able to account for these effects in climate m...

The uniquely vulnerable West Antarctic Ice Sheet holds enough water to raise global sea levels by 5 meters. But when that will happen — and how fast — is anything but settled.

Typhoon leaves flooded Alaska villages facing a storm recovery far tougher than most Americans will ever experience

Twila Moon has been studying the Greenland Ice Sheet for 20 years. In some ways, Greenland's tipping point has already been crossed: A certain amount of ice loss is locked in for centuries or millennia. But how fast it goes is up to humans, now thebulletin.org/premium/2025...
The shrinking of the Greenland Ice Sheet can’t be stopped—but it can and must be slowed
Ice loss in Greenland is already large, irreversible, and greatly accelerated after centuries of near stability. Though a tipping point for future ice loss has already been crossed, the pace of this l...
