    Atmospheric Scientists Win Early Career Awards

    Two scientists at Lamont-Doherty Earth Observatory have been recognized for early-career achievement in the atmospheric sciences by the American Geophysical Union (AGU), the world’s largest earth-sciences organization. Tiffany Shaw, 31, is a physicist who uses computer models and mathematical equations to study the basic dynamics of the atmosphere and climate, for instance, how the jet…

    Climate Underpinnings of East Africa Drought

    Watch a video interview of climate scientist Brad Lyon on the conditions leading up to the ongoing drought in East Africa. He says there’s a chance of La Niña forming later in the year, which could have devastating consequences for a region already plagued by widespread famine.

    End of the Line – Good Byes to a Great Field Season in Peru

    After more than six weeks trawling the Peruvian Andes in search of palaeoclimate clues, our field team is visiting the last site, a potential calibration sites near Coropuna. The objective of that ongoing work is to refine the cosmogenic surface-exposure method for the tropics, thereby improving the precision of new and existing datasets.

    Obstacles to Capturing Carbon Gas, NYTimes, July 31 Carbon capture and sequestration is a technology that traps carbon dioxide and stores it, usually underground in a geological formation. The process, already used by oil and natural gas companies, presents the opportunity for capturing CO2 from power plants and other sources of carbon emissions as a…

    The Role of Drought in the Horn of Africa Famine

    Let’s get this out of the way. The current famine in the Horn of Africa isn’t caused by drought. Rather, a complex mix of societal and political factors created a dangerous situation. The worst drought in 60 years (pdf) is what pushed that situation over the edge into a humanitarian crisis. However, just as these…
