Game Theory Shows How Tragedies of the Commons Might be Averted

Lake Lanier in Georgia is the primary water reservoir serving suburban and metropolitan Atlanta. When the lake’s water level drops below a certain point, calls go out for water conservation and news reports show images of the red mud shoreline. In some affected counties, water restrictions are imposed. The combination of usage restrictions and changes in precipitation eventually averts the crisis. But, when the crisis ends, water usage rebounds – until the next shortage.

With Droughts and Downpours, Climate Change Feeds Chesapeake Bay Algal Blooms

Nitrogen-rich agricultural runoff into the Chesapeake Bay presents an ongoing environmental and economic concern for the bay's massive watershed. Pollution from fertilizer application feeds algal blooms that poison humans and marine life, and devastate fisheries.

Researchers Pinpoint Abrupt Onset of Modern Day Indian Ocean Monsoon System

120901_web.jpg

A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.

Drought Stalls Tree Growth and Shuts Down Amazon Carbon Sink, Researchers Find

119112_web.jpg

A recent drought completely shut down the Amazon Basin's carbon sink, by killing trees and slowing their growth, a ground-breaking study led by researchers at the Universities of Exeter and Leeds has found. Previous research has suggested that the Amazon -the most extensive tropical forest on Earth and one of the "green lungs" of the planet -- may be gradually losing its capacity to take carbon from the atmosphere. This new study, the most extensive land-based study of the effect of drought on Amazonian rainforests to date, paints a more complex picture, with forests responding dynamically to an increasingly variable climate.
