Hurricanes & Global Warming: Mixing Science & Politics

Since Hurricane Katrina, there has been an increasing concern that a changing climate will bring about more frequent and more intense extreme weather events. This concern has motivated scientists to investigate the connection between global warming and extreme events such as hurricanes, and it has also made climate change a hot-button political issue. In this lecture, Dr. Greg Holland, director of Mesocale and Microscale Meteorology Division at the National Center for Atmospheric Research, discusses the scientific evidence that suggests a connection between global warming and hurricanes and comments on the political ramifications of this connection.

Science publishes article on based on AGCI's 2008 workshop on Nutrient Imbalances in Agricultural Development

In a 2008 AGCI meeting entitled "Managing the Cycles of Nitrogen and Phosphorous: Mitigation and Adaptation," a small working group convened to identify and develop the information that society needs to respond effectively to anthropogenic changes in the cycles of nitrogen and phosphorous. This article, published in the 19 June 2009 edition of Science, outlines how nutrient additions to intensive agricultural systems range from inadequate to excessive -- and how both extremes have substantial human and environmental costs.

The New York Times' Andy Revkin reports on the Science article in his Dot Earth blog. Scientific American and Science Daily also reported on the paper.
