Dark Shadows Fall on Melting Icecap

Dust blowing onto the Greenland icecap from warming areas of the Arctic is causing the ice to melt faster by reducing the whiteness that reflects light and keeps it cool.

Ocean Winds Put Heat on Australia

Winds of change caused by greenhouse gases in the Southern Ocean are keeping Antarctica cold but parching Australia by “stealing” more of its rainfall.

Cold and Warm Polar Water Mixing Slows

The process that sends cold surface Antarctic water to the warmer depths—redistributing heat and storing carbon—is now faltering, scientists say, because of climate change.
