A new assessment report by the USGS, the second in a series, found that ecosystems in the western U.S. were a net carbon sink between the years 2001 and 2005, meaning they took up carbon equivalent to 4.9 percent of the nation’s 2010 net fossil-fuel emissions.
The 2000-2004 drought in western North America was the worst drought in the past 800 years, according to a new study in Nature Geoscience. Western North America is currently a carbon sink—a reservoir, such as oceans or plants, that absorbs carbon dioxide.
North America has at least 500 years of storage in geologic formations that could accommodate carbon dioxide emissions from industrial sources.
Climate change will reduce the production of natural forage for livestock in California, as well as reduce the ability of forests to store carbon dioxide, according to a new study in Climatic Change.
The U.S. Department of Energy is investing $41 million to spur the development of carbon sequestration technologies, according to a DOE press release.
