Study of Southern Ocean critical to understanding of climate change
Whether it's the economics of clean energy, the politics of Washington or claims over the severity of the problem itself, the debate over climate change is loud and crowded. One aspect that often goes overlooked ...
Fugitive Sea Shepherd founder hands over reins
The fugitive founder of Sea Shepherd has stepped down from key roles at the militant anti-whaling group, passing the Antarctic harpoon chase mantle to a former Australian politician.
Global ocean salinity changing due to anthropogenic climate change
Rising sea surface temperatures, climbing sea levels, and ocean acidification are the most commonly discussed consequences of anthropogenic climate change for the global oceans. They are not, however, the only potentially ...
Antarctic sea ice thickness affects algae populations
In the waters off Antarctica, algae grow and live in the sea ice that surrounds the southern continent-a floating habitat sure to change as the planet warms. As with most aquatic ecosystems, microscopic algae form the base ...

Tropical Indo-Pacific climate shifts to a more El Nino-like state, research finds
Climate models predict a slowdown of the Walker circulation with global warming. Atmospheric models, however, have failed to reproduce the slowdown already observed over the last 60 years, casting doubt on ...
La Nina caused global sea level drop
The 2011 La Niña was so strong that it caused global mean sea level to drop by 5 millimeters (0.2 inches), a new study shows. Since the early 1990s, sea level has been rising by about 3 millimeters (0.1 inches) per year, ...
Opposite behaviors? Arctic sea ice shrinks, Antarctic grows
The steady and dramatic decline in the sea ice cover of the Arctic Ocean over the last three decades has become a focus of media and public attention. At the opposite end of the Earth, however, something ...
