Decreasing emissions of black carbon, methane and other pollutants makes a difference
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.
Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.
The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)
Protecting the nation from terrorism, breaches in cyber security and other threats inside its borders is such a massive undertaking it is “not easy to draw red lines” that can chart individual or departmental responsibilities, Secretary of Homeland Security Janet Napolitano said during a campus visit on Oct. 6.

Her talk in the Law School’s Levinson Auditorium highlighted the importance of international partnerships in that mission. (more…)
