Punta Arenas, Chile, Feb. 28, 2008 ---Scientists from over a dozen institutions will embark today from this port on the tip of South America to spend 42 days amid the high winds and big waves of the Southern Ocean, where they will make groundbreaking measurements to explain how large amounts of climate-affecting gases move between atmosphere and sea, and vice-versa. Researchers from Columbia University’s Lamont-Doherty Earth Observatory are taking a leading role in the expedition.

January 14, 2008 - Lamont Scientists Douglas Martinson and Robin Bell were featured in an NBC Nightly News story entitled "Meltdown in Antartica."
The story is part of Nightly News' ongoing "Our Planet" series that examines issues effecting the earth's environment.

January 10, 2008 ---Zigzagging some 60,000 kilometers across ocean floors, earth’s system of mid-ocean ridges plays a pivotal role in many workings of the planet—from its plate-tectonic movements to heat flow from the interior, and the chemistry of rock, water and air....

December 19, 2007 - Science at Columbia University’s Lamont-Doherty Earth Observatory is featured in three new books—not all in the usual nonfiction format. In addition to two journalistic works on climate change, there is Time and Materials, by Robert Hass, former poet laureate of the United States, which contains “State of the Planet: on the occasion of the fiftieth anniversary of Lamont-Doherty Earth Observatory. In it, Hass explores humanity’s efforts to understand the complexities of oceans, earth and skies, with climate as a central theme.

Dec 10, 2007--Scientists from Columbia University’s Lamont-Doherty Earth Observatory will report this week on vital topics including new evidence of the effects of climate change; technologies to confront it; studies of eastern U.S. earthquake risk; and previously unseen inner workings of the deep polar ice caps. The reports will be presented at the fall 2007 American Geophysical Union (AGU), the largest earth-sciences gathering in the world, Dec. 10-14 in San Francisco.

November 30, 2007 - Amid cheers from hundreds of scientists and guests, Columbia’s Lamont-Doherty Earth Observatory cut the ribbon at its $45 million Gary C. Comer Geochemistry Building. The ultra-modern facility is “the step forward that we need to accelerate our efforts to understand and predict the important changes that will impact the way we live with our planet,” Lamont director G Michael Purdy told the crowd. It comes “at a time when, after decades of apathy, humankind is at last awakening to the critical role that the planet’s environment plays in everyone’s well-being.”

November 12, 2007 -The academic community’s flagship seismic-research vessel, to be operated by Lamont-Doherty Earth Observatory, was dedicated in Galveston, Tex., Nov 12. The R/V Marcus G. Langseth, funded by the U.S. National Science Foundation for use by universities, research institutes and government agencies across the nation, will generate CAT-scan-like 3D images of magma chambers, faults and other structures miles below the world’s seabeds.

October 19, 2007--The 2007 Nobel Peace Prize, awarded jointly to Al Gore and the Intergovernmental Panel on Climate Change (IPCC), honors many Lamont-based scientists who have contributed work to the IPCC. These include at least nine current staffers who collaborated with the IPCC’s most recent assessment, issued in 2007. Many others have contributed to the panel’s three previous reports over the past 17 years.

July 15, 2007 - The 11th Hour is a 2007 feature film documentary created, produced and narrated by Leonardo DiCaprio on the state of the natural environment.
Lamont’s own Associate Professor Peter deMenocal is one the climate change experts interviewed in the film.
May 14, 2007
A study released on May 11, 2007 provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. Scientists believe the carbon dioxide (CO2) releases helped propel the world into further warming.
New Study Shows Climate Change Likely to Lead to Periods of Extreme Drought in Southwest North AmericaApril 06, 2007
April 6, 2007 - How anthropogenic climate change will impact the arid regions of Southwestern North America has implications for the allocation of water resources and the course of regional development. The findings of a new study, appearing in Science, show that there is a broad consensus amongst climate models that this region will dry significantly in the 21st Century and that the transition to a more arid climate may already be underway. If these models are correct, the levels of aridity of the recent multiyear drought, or the Dust Bowl and 1950s droughts, will, within the coming years to decades, become the new climatology of the American Southwest.

January 18, 2007 - The Royal Swedish Academy of Sciences has decided to award the Crafoord Prize in Geosciences for 2006 to Wallace S. Broecker, Newberry Professor of Earth and Environmental Sciences at Lamont-Doherty Earth Observatory, “for his innovative and pioneering research on the operation of the global carbon cycle within the ocean-atmosphere-biosphere system, and its interaction with climate"

Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth Observatory and the Earth Institute at Columbia University, recently learned that two-thirds of the seismometers she placed on the floor of the Pacific Ocean were trapped more than 8,000 feet (2500 meters) underwater, it turned out to be an extremely good sign.

What’s in an isotope? Quite a lot, as it turns out. A new technique developed by researchers at the Lamont-Doherty Earth Observatory now allows scientists to use an isotope of manganese not abundant on Earth to understand the record of millions of years of changes to the Earth’s surface. According to the study's lead scientists, the new technique relies on measuring extremely small amounts of the nuclide that accumulates as cosmic rays strike exposed rock surfaces over long periods of time. This will allow scientists to track processes such as erosion and glaciation that shaped the landscape over millions of years.
