		About the ESSN

The ESSN is the private, nonprofit membership organization for past and current recipients of NASA Earth System Science (ESS) fellowships and awards from the New Investigator Program (NIP) in Earth Science. The ESSN provides the leading forum for integrating knowledge across all components of the Earth system, and is building the comprehensive understanding necessary to protect our home planet.

ESSN makes NASA's 2004 Year In Review

Earth System Scholars Fueling the S&T Workforce - Anticipating the challenges in understanding and predicting change in the highly complex Earth system, NASA has invested over a decade in preparing the next generation of Earth system scholars who are particularly equipped to advance our understanding of Earth using data from the unprecedented fleet of advanced Earth observing satellites. The scientists and engineers from NASA’s Earth System Science Fellowship Program (graduate) and the New Investigator Program (early career) now work in many sectors in the U.S. and abroad, including basic and applied research, policy, and industry. Many are leaders in their respective fields. Their desire to collaborate with each other and continue to contribute to NASA’s Mission to understand and protect our home planet has prompted them to form the Earth System Scholars Network. These highly motivated and scientifically sophisticated individuals, in turn, educate and inspire another generation of Earth system scholars. They are our science and technology workforce, fueling the Nation’s competitiveness, economy, and security.

Climate Variability and Change
	Tiny airborne particles are a major cause of climate change Published [07/23/2006] Source [American Committee for the Weizmann Institute of Science] A scientist at the Weizmann Institute of Science and his colleagues caused a storm in the atmospheric community when they suggested a few years back that tiny airborne particles, known as aerosols, may be one of the main culprits causing climate change � having, on a local scale, an even greater impact than the greenhouse gases effect. Attempts to understand how these particles influence clouds have generated many uncertainties.

Atmospheric Composition
	Power plants are major influence in regional mercury emissions Published [07/21/2006] Source [Yale University] The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies.

Carbon Cycle and Ecosystems
	Direct link established between tropical tree and insect diversity Published [07/22/2006] Source [Smithsonian Tropical Research Institute] Higher tree species diversity leads directly to higher diversity of leaf-eating insects, researchers report in the July 13, 2006 early-online version of the journal Science.

Water and Energy Cycle
	Rise in sea level, loss of wet lands may account for unstable ground in Mississippi Delta Published [07/21/2006] Source [National Science Foundation] While erosion and wetland loss have become huge problems along Louisiana's coast, the land 30 to 50 feet beneath much of the Mississippi Delta has been very stable for the past 8,000 years, with low to nonexistent subsidence rates. So say geoscientists from Tulane University and Utrecht University in the Netherlands, challenging the notion that subsidence, or sinking of the earth, bears much of the blame for Louisiana's coastal geology problems.

Weather
	El Ni�o Phenomenon Could Help Reforest Semi-arid Regions Published [07/23/2006] Source [Universitat Autonoma De Barcelona] Universitat Aut�noma de Barcelona scientists took part in an international cooperation project to study the El Ni�o phenomenon and its effects on vegetation. By observing the relationship between the development of two species (Prosopis pallida and Prosopis chilensis) and the El Ni�o cycles (which have varying intensity), they have reached the conclusion that the increase in precipitation could be used to recover semi-arid zones through reforestation programmes.

Earth Surface and Interior
	Exposure to volcanic mineral associated with increased mesothelioma incidence in Turkey Published [07/23/2006] Source [Journal of the National Cancer Institute] High exposure to a fibrous volcanic mineral called erionite was associated with a high incidence of a type of cancer called mesothelioma, according to a study in the March 15 issue of the Journal of the National Cancer Institute.
