A new study suggests warm water is melting Antarctica's ice shelves from below, speeding the inland ice loss rate.
In most of the world, the thermometer began to shoot up only after the atmosphere was spiked with CO2.
To understand how much the sea is likely to rise in the future, it's important to how understand how ice responded to warming in the past.
Ozone is starting to plummet over the Arctic — but the ozone holes here and in Antarctica are pretty much unrelated to climate change, despite perceptions to the contrary.
A new study finds the rate at which the massive ice sheets in Greenland and Antarctica are melting has been accelerating during the past two decades.
Scientists are surprised to learn that the planet's biggest ice sheet is growing from the bottom up as well as the top down.
