Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study.

Drilling, experiments, target huge formations off West Coast
Palisades, N.Y., July 14, 2008—A group of scientists has used deep ocean-floor drilling and experiments to show that volcanic rocks off the West Coast and elsewhere might be used to securely imprison huge amounts of globe-warming carbon dioxide captured from power plants or other sources. In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. CO2 production

From asteroid impacts and climate change to oceanography and microbiology, undergraduates will spend ten weeks conducting exciting and often ground-breaking scientific research in the Earth Intern program. The program matches students with a research scientist at The Earth Institute at Columbia University’s Lamont-Doherty Earth Observatory (LDEO) in Palisades, New York. LDEO’s more than 200 research scientists are global leaders in the search for knowledge about the origin, evolution and future of the natural world. The intern program is co-sponsored by LDEO, The Earth Institute, Barnard College, and the Department of Earth and Environmental Sciences at Columbia.

Three scientists at Columbia’s Earth Institute have been elected to leading U.S. scientific academies.
Paul E. Olsen, a paleontologist and climate researcher at Lamont-Doherty Earth Observatory, was elected to the National Academy of Sciences. Lamont seismologist Paul G. Richards was elected to the American Academy of Arts & Sciences, along with agronomist Pedro Sanchez, who heads the Earth Institute’s Tropical Agriculture Program.

Farming pushed natural drought into disaster--and could do so again.
NEW YORK – Climate scientists using computer models to simulate the 1930s Dust Bowl on the U.S Great Plains have found that dust raised by farmers probably amplified and spread a natural drop in rainfall, turning an ordinary drying cycle into an agricultural collapse. The researchers say the study raises concern that current pressures on farmland from population growth and climate change could worsen current food crises by leading to similar events in other regions.

The Earth Institute is holding two seed funding competitions for the '08 - '09 fiscal year (July 1-June 30). One competition is for Cross-Cutting Initiative (CCI) projects and one for Earth Clinic projects. Proposals for both competitions are due by the close of business on Monday, June 2, 2008 and should be e-mailed to Robin DeJong at firstname.lastname@example.org.
Both competitions are designed to provide seed funding for new internal research or projects/interventions that further the Earth Institute mission which states that:

WASHINGTON, Mar. 17, 2008 ---Every mode of transportation in the United States will be affected by climate change, and planning to keep things running must begin now, says a new report to the government. The greatest potential impact will be flooding of roads, railways, transit systems, and airport runways in coastal areas, due to rising sea levels and surges brought on by more intense storms. Transport on rivers and roads in the nation’s center also are at risk, says the report, issued this week by the National Research Council. A committee of authors warns that climate shifts will require significant changes in design, construction, operation and maintenance of transportation systems.

Researchers from Columbia University’s Lamont-Doherty Earth Observatory are taking a leading role in the expedition.
