Studies Find Climate Change to Disrupt Antarctic and Tropical Ecosystems

Krill shortages will impact Adélie penguins’ foraging and reproductive abilities.

A recent study finds that West Antarctica’s ecosystem is highly correlated to its climate. As a result, climate change will have a negative impact on its ecological relationships, from plankton to penguins. Antarctica isn’t alone – climate change will also affect tropical ocean ecosystems by causing mass coral bleaching.

It seems that many of the local fishermen have gone to hunt Narwal further north but there are several good prospects for boats that Søren will scout further as several of the fishermen are sleeping as the fishing is better right now at night. With 24 hours of daylight day or night fishing doesn’t really seem to matter.

Project Background: Changing conditions in Greenland’s northwest glaciers over the last decade have led to a range of questions about water temperature and circulation patterns in the fjords where ocean water meets the glacial fronts.

NASA has named Gavin A. Schmidt to head its Goddard Institute for Space Studies (GISS), an affiliate of Columbia University’s Earth Institute.

Currently serving as deputy director, Schmidt takes over from long-time director James E. Hansen, who retired last year to open a separate climate science and advocacy center at the Earth Institute.

On Monday, June 2, President Obama will announce proposed federal rules aimed at curbing carbon emissions from existing U.S. power plants–possibly a landmark in U.S. climate policy. It is uncertain how far the rule will go, and the announcement is being closely watched around the world.

How High Will Sea Levels Rise?

Scientists from Lamont-Doherty Earth Observatory are trying to determine how high sea levels may rise in the future by studying the shorelines of the past. Led by a team of researchers including Lamont climate scientist and marine geologist Maureen Raymo, the goal of Pliomax is to increase the accuracy of global sea level estimates for the Pliocene era, which occurred about 3 million years ago.

Climate and the Opal Artisans of the Sea

Tiny one-celled organisms called radiolaria are ubiquitous in the oceans, but various species prefer distinct habitats. Thus it aroused considerable intrigue in 2012 when protozoa specialist O. Roger Anderson and colleagues published a study showing that radiolaria normally found near the equator were suddenly floating around in arctic waters above Norway. Was this a sign that global climate change was bringing an invasion of warm-weather plankton?
