Bill Chameides

of Duke University

Dr. Bill Chameides, Dean of Duke's Nicholas School of the Environment since 2007, has combined more than 30 years in academia as a professor, researcher, teacher, and mentor with a 3-year stint in the nonprofit world as the chief scientist of Environmental Defense Fund. He is a member of the National Academy of Sciences, a fellow of the American Geophysical Union, and a recipient of the American Geophysical Union’s MacElwane Award.  

Bill has served on numerous national and international committees and task forces and was named a National Associate of the National Academies in recognition of "extraordinary service." In November, 2008, he was appointed the Vice Chair of the Committee on America’s Climate Choices, commissioned by Congress to develop a multidecadal road map for America’s response to climate change.

Bill’s research focuses on the atmospheric sciences, elucidating the causes of and remedies for global, regional, and urban environmental change and identifying pathways towards a more sustainable future. Specifically, his research helped lay the groundwork for our understanding of the photochemistry of the lower atmosphere, elucidated the importance of nitrogen oxides emission controls in the mitigation of urban and regional photochemical smog, and the impact of regional environmental change on global food production. He earned his B.A. from SUNY Binghamton and his M.S. and Ph.D. from Yale University.

In late September more than 865,000 gallons of Bakken oil spewed from a pipeline onto a North Dakota farmer’s wheat fields.

Another crack in the “fracking is safe” story for the industry to address.

OK, with the government shutdown that kicked in at midnight this morning, it should come as no surprise that we have a highly dysfunctional Congress. Still, when Congressional gridlock derails a good, sensible, popular bill on energy efficiency in a country that harnesses less than half of the energy we produce and loses almost 30 percent due to inefficiencies, at least some attention should be paid.

Long-awaited research results suggest methane leakage small.

… in three regions. When it comes to climate change, coal, the dirtiest of the fossil fuels, is a definite baddie — BTU for BTU, burning it puts out almost 30 percent more carbon dioxide (CO2) than burning petroleum and about 78 percent more CO2 than natural gas. Want to fight climate change? Then you…

Was lack of government regulation at fault?

Could your neighborhood be next? Neighborhoods can be turned upside down by shale oil and shale gas drilling (see here and here), by pipelines dug through backyards, and by pipeline spills that send crude oil across entire neighborhoods. All of it gives me the willies, but it’s always been theoretical willies as the prospects of something like…

The United States and China are talking different languages when it comes to reducing carbon emissions.

The story of coal ash keeps going nowhere. Unfortunately, the same can’t be said about coal ash.

Global greenhouse gas emissions are higher than ever. What’s to be done? “Redrawing the Energy-Climate Map,” a special report [pdf] by the International Energy Agency (IEA), was released on Monday, and the findings are sobering. (See related story: “What’s Behind the New Warning on Global Carbon Emissions?“) In 2012 energy-related, global carbon dioxide (CO2) emissions…
