DOUBLE DOUBLE BOIL AND TROUBLE
The Witches' Brew of environmental collapse is increasingly showing scientists' predictions being out by orders of magnitude. As a trend analyst, I would say this phenomenon is indicating an emerging trend.

Alarming new research suggests warm seawater is rushing under the ice, perhaps doubling the rate of melting.
current glacier melt models don’t account for a phenomenon called tidal pumping. Whenever the tide rises, it heaves Thwaites’ ice sheet upward, allowing relatively warm seawater to rush farther upstream underneath the glacier. That drives melting along its belly, making the ice sheet more prone to fracture. “It means that warm water that is at the bottom of the glacier can infiltrate up to several kilometers upstream,” says University of Houston physicist Pietro Milillo, who is studying Antarctic glaciers.
