For 20 years, the international community has been unable to agree on a coordinated way to reduce greenhouse gas emissions. J. Timmons Roberts, the Ittleson Professor of Environmental Studies and Sociology, has co-authored a four-step compromise toward emissions reduction that offers “effectiveness, feasibility, and fairness.”

PROVIDENCE, R.I. [Brown University] — Climate change is an issue of urgent international importance, but for 20 years, the international community has been unable to agree on a coordinated way to reduce greenhouse gas emissions. In a “Perspective” piece published in the June issue of Nature Climate Change, J. Timmons Roberts, the Ittleson Professor of Environmental Studies and Sociology, proposes a four-step compromise toward emissions reduction that offers “effectiveness, feasibility, and fairness.” (more…)

The amount of carbon dioxide escaping from rivers and streams into the atmosphere is much larger than previously thought, according to a new study that maps for the first time the flux of CO2 from inland waters worldwide. Published in the journal Nature, the research reveals the major role these waterways play in the global carbon cycle, the authors said.

“This study solidifies the significance of inland waters as conduits of exchange and provides a framework for inclusion of this exchange in regional and global studies,” said lead author Peter A. Raymond, a professor of ecosystem ecology at the Yale School of Forestry & Environmental Studies (F&ES). “Understanding how ecosystems exchange carbon is important, as they currently offset a significant percentage of emissions caused by human activity.” (more…)
