Climate scientists say that killer heat waves will become increasingly prevalent in many regions as climate warms. However, most projections leave out a major factor that could worsen things: humidity, which can greatly magnify the effects of heat alone. Now, a new global study projects that in coming decades the effects of high humidity in many areas will dramatically increase.

The coasts of Antarctica are ringed with ice shelves – large expanses of ice that float on the surrounding ocean and form the outermost extensions of the glaciers that cover the land behind them. A new study shows that even minor deterioration of ice shelves can instantaneously hasten the motion and loss of ice hundreds of miles landward.

As climate warms, the surface of the Greenland ice sheet is melting, and all that meltwater ends up in seasonal rivers that flow to the sea. At least that is what scientists have assumed until now. A new study shows that some of the meltwater is actually being soaked into porous subsurface ice and held there, at least temporarily.
