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.

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.

For several decades, geologists have thought the western North American tectonic plate was riddled with a type of fault that permitted the continent to expand over the past several million years. However, a new study published in the November issues of The Journal of Geology challenges that assumption and suggests that these faults are actually the remains of massive, gravity-driven rock slides and not tectonically active features of the Earth's crust.

Marie Tharp, a pathbreaking oceanographic cartographer at the Lamont-Doherty Earth Observatory, co-creator of the first global map of the ocean floor and co-discoverer of the central rift valley that runs through the Mid-Atlantic Ridge died Wednesday August 23 in Nyack Hospital. She was 86.

Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes in the Earth's past climate.
Columbia University Receives $16.9 Million Award from National Institute of Environmental Health SciencesJuly 26, 2006
Researchers at Columbia University’s Mailman School of Public Health, Lamont-Doherty Earth Observatory and Center for International Earth Science Information Network announced that they have been awarded a five-year, $16.9 million grant renewal from the National Institute of Environmental Health Sciences (NIEHS) Superfund Basic Research Program (SBRP).

The destruction caused by natural disasters such as Hurricane Katrina and human activities such as mountaintop removal mining are powerful examples of how the environment and society are tightly interwoven. But to what extent do, or should, state science curricula in the U.S. seek to investigate or influence the nature of this interaction?

Mikah McCabe wanted "some serious research experience" on global warming or climate change. Hagar ElBishlawi wanted to work in a program affiliated with The Earth Institute. Michael Silberman wanted to work at Lamont because the people there work on the "interesting and important problems."
Each of the undergraduate interns welcomed by Lamont-Doherty Earth Observatory this summer may have had their own reason for applying, but they all have one thing in common: they are some of the best and brightest.
New Study of Glacial Retreat Shows that Much of the World Emerged from Last Ice Age at Nearly the Same TimeJune 08, 2006
The end of the recurring, 100,000-year glacial cycles is one of the most prominent and readily identifiable features in records of the Earth's recent climate history. Yet one of the most puzzling questions in climate science has been why different parts of the world, most notably Greenland, appear to have warmed at different times and at different rates after the end of the last Ice Age.

With the summer approaching, new research has shown that recent water emergencies in the Northeast have resulted from more than just dry weather
