    Scientists broadly agree that global warming may threaten the survival of many plant and animal species; but global warming did not kill the Monteverde golden toad, an often cited example of climate-triggered extinction, says a new study.

    This week U.S. and Haitian scientists will start a 20-day research cruise off Haiti to address urgent questions about the workings of the great Jan. 12 earthquake, and the possibility of continuing threats. They hope to gather sonar images, sediments and other evidence from the seafloor that might reveal hidden structures...

    Natalie Boelman is an ecologist at Lamont-Doherty Earth Observatory who studies the effects of climate change on organisms throughout the food chain. She first visited the Alaskan Arctic in 2001, and will return to the North Slope this spring and summer to continue a wildfire-mapping project and to set up a field study that will look at how warming-induced changes are affecting migratory songbirds that breed on the tundra each summer.

    The Earth Institute is soliciting proposals from Columbia University faculty and research staff for two seed funding competitions this year as part of the Cross-Cutting Initiative (CCI) and the Earth Clinic. Proposals for both competitions are due by April 30, 2010, and should be e-mailed to Adrian Hill at ahill@ei.columbia.edu.

    Scientists aboard the research ship the JOIDES Resolution recently drilled two kilometers into Earth’s crust, setting a new record for the deepest hole drilled through the seafloor on a single expedition.

    O. Roger Anderson is a microbiologist at Lamont-Doherty Earth Observatory who studies bacteria, amoebas, fungi and other microorganisms. Lately he has been thinking about how tiny organisms that inhabit the vast northern tundra regions could contribute to changing climate, since, like humans, they breathe in oxygen and breathe out carbon dioxide.

    The earthquake that struck Haiti took place along what is called a strike-slip fault—a place where tectonic plates on each side of a fault line are moving horizontally in opposite directions, like hands rubbing together. When these plates lock together, stress builds; eventually they slip; and this produces shaking.

    New York subway commuters may worry more about rats and rising fares than dust floating through the system, but for the workers who spend their whole shift below ground, air quality has long been a concern. Results from a new pilot study using miniaturized air samplers to look at steel dust exposure may help them breathe easier.

    Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources.

    Selected posts from a continuing series of essays and interviews from LDEO scientists on the prospects for a global climate-change treaty.

    Each person on the planet produced 1.3 tons of carbon last year—an all-time high--despite a global recession that slowed the growth of fossil fuel emissions for the first time this decade, according to a report published this week in the journal Nature Geoscience. Emissions grew 2 percent last year, to total 8.7 billion tons of carbon dioxide.

    The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions...

    Training teachers to do science in the field or laboratory measurably increases the academic performance of their students and may have far-reaching economic benefits, according to a study published this week in the journal Science. The number of high school students passing New York State’s standardized tests, the Regents exams, is raised by as much as 10 percentage points if the teachers participated in Columbia University’s Summer Research Program for Science Teachers, the study found.

    Before airplanes and satellite phones, polar exploration was a more dangerous undertaking than it is now. A new article in American Scientist retraces Nansen and Shackleton's expeditions from the perspective of modern ocean conditions and sea ice drift conditions.

  • October 09, 2009

    Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago.
