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 methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. Kholod is a scientist at the Joint Global Change Research Institute, a partnership between PNNL and the University of Maryland where researchers explore the interactions between human, energy and environmental systems.

Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

Based on future world energy demand projections, they estimate that if growth of unconventional heavy oil production continues unabated, the incremental GHG emissions that results from replacing conventional oil with heavy oil would amount to 4–21 Gt-CO 2 eq over four decades (2010 by 2050).
