===== How climate change is intensifying hurricanes ===== | |||

Extreme weather seems to make the headlines almost every week, as disasters increasingly strike out of season, break records, and hit places they never have before. | |||
===== Rising surface salinity and declining sea ice: A new Southern Ocean state revealed by satellites ===== | |||

For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the upward transport of subsurface heat and possibly contributing to sea ice expansion. | |||
===== Is a monster web of ocean currents headed for collapse? The race is on to find out ===== | |||

Although it doesn’t look like it, the Arctic waters are balmy in February, relative to the air temperatures, which can fall below −30 °C. On the screen of Stephens’s remote control, the pancake-shaped floes show up in the thermal images as dark circles, whereas open water and thin ice glow bright orange, indicating energy escaping from the ocean into the frigid polar air. | |||
