US DOI report highlights impacts of climate change on Western water resources

Green Car Congress

Projected median temperature change in °F (of 112 climate projections) over the Western United States, 2070–2099 relative to 1950–1979. The report, which responds to requirements under the SECURE Water Act of 2009, details several increased risks to western United States water resources during the 21 st century.

New ORNL tool to assess global freshwater stress suggests that population growth could be a bigger factor in water availability than increasing temperatures

Green Car Congress

An Oak Ridge National Laboratory (ORNL) paper published in Computers & Geosciences outlines a process that might help to determine the relative importance of population increases vs. climate change. Our work establishes a new method to couple geographic information system data with global climate outputs and statistical analysis.

Study Finds Water Use for Switchgrass Ethanol Production Approximately the Same as for Gasoline

Green Car Congress

In the US, producing one gallon of ethanol from switchgrass consumes approximately the same net amount of water as does producing a gallon of gasoline from conventional crude or oil sands oil, according to a study by Argonne National Laboratory researchers presented at the 238 th national meeting of the American Chemical Society last week.

Study Finds Warmer Climate Could Stifle Carbon Uptake by Trees

Green Car Congress

A new CU-Boulder study indicates subalpine forests in the West will soak up less carbon dioxide as the climate warms and the growing seasons lengthen. The water-stressed trees were then less effective in converting CO 2 into biomass. Snow is much more effective than rain in delivering water to these forests,” said Monson. “If

Researchers Predict Permafrost Thaw Will Intensify Climate Change More Quickly Than Previously Thought; Melting of Greenland Icesheet Could Drive More Water Than Previously Thought to North American Northeast

Green Car Congress

Before this study, we didn’t know how fast that carbon could potentially be released from permafrost, and how this feedback to climate would change over time. An understanding of the rate of carbon release is necessary to estimate the strength of positive feedback to climate change, a likely consequence of permafrost thaw. Permafrost.
