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

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. Globally, coal mining is decreasing in the United States and Europe but increasing rapidly in other parts of the world, such as southeast Asia and India.

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.
