Iron Increase In Oceans And Correlated Decrease Of CO2 Levels? A Study

Researchers from Princeton University and the Swiss Federal Institute of Techonology in Zurich have confirmed that during the last ice age iron fertilization caused plankton to thrive in a region of the Southern Ocean. Iron fertilization has also been suggested as one way to draw down the rising levels of CO2 associated with the burning of fossil fuels.

U.S. Scientists Launch Wake-Up Campaign on Climate Change

In an unusual intervention in policy debates, the American Association for the Advancement of Science (AAAS) warned Tuesday that the world was “at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts.”

Southern Patagonia Ice Field

With an area of 13,000 square kilometers (5,000 square miles), the Southern Patagonia Ice Field is the largest temperate ice sheet in the Southern Hemisphere. This grand panorama shows that many glacier tongues showed significant annual “retreat” of their ice fronts, a familiar signal of climate change.
