Climate Change

An hour south of Pittsburgh, in Pennsylvania’s Washington County, millions of gallons of wastewater from hydraulic fracturing wells are stored in large impoundment ponds and so-called "closed container" tanks. The wastewater is then piped to treatment plants, where it is cleaned up and discharged into streams; trucked to Ohio and pumped deep down injection wells; or reused in other fracking operations.

Different patterns of urban development may have widely varying long-term effects on greenhouse gas (GHG) emissions. To investigate such effects, we used UPlan geographic information system–based software to model three 2050 urban-growth scenarios for Yolo County, a predominantly agricultural area near Sacramento, Califor- nia. Two scenarios correspond to the Intergovernmental Panel on Climate Change’s A2 and B1 storylines.

Economic factors within China are also prompting the government to look outside the country for agricultural land. Jia-Ching Chen, a research fellow at Brown University who studies the tensions between urbanization and rural land use in...

In 2012, through a Switzer Leadership Grant, I had the opportunity to join the Adirondack Chapter of The Nature Conservancy to help advance work in freshwater conservation and climate change adaptation in the bi-national Lake Champlain Basin.

Solar power is growing so fast in California — with installations by customers increasing tenfold since 2006 — that it is turning the state’s power system upside down.

"Reaching 400pm is a stark reminder that the world is still not on a track to limit CO2 emissions and therefore climate impacts. We're still on the 'business-as-usual' path, and adding more and more CO2, which will impact the generations ahead of us. Passing this mark should motivate us to advocate for focused efforts to reduce emissions across the globe." Read more quotes from NASA scientists on the 400 ppm carbon milestone

Bipartisan Policy Center President Jason Grumet and other members of the Washington think tank welcomed a plan for a federal energy review. "It's good to have a plan but what really matters is execution," Grumet said Thursday, responding to a White House announcement that it had begun its Quadrennial Energy Review. "Having all of the key agencies involved in a process like the QER increases the likelihood that the plan will lead to coordinated action," Grumet said.

This reference resource, in atlas format, is an online-only compendium of maps and data sets accompanied by multimedia elements designed to illustrate key concepts in green issues and environmentalism graphically and interactively. Topics for the maps presented in this work were selected from articles in the 12-volume SAGE Reference Series on Green Society: Toward a Sustainable Future. Each map includes links to one or more of the series articles. Maps include interactive components, with clickable icons to deliver the data and statistics that make up each map.
