Red colors represent a temperature increase, blue indicates a decrease, and beige indicates no change. In their paper, the authors note that several cautions must be taken in analyzing long-term climatic data in order to avoid misleading or erroneous conclusions. Mean annual temperature is changing throughout Alaska. 2009, 1949?

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

Green Car Congress

Global CO 2 emissions from fossil fuel use and cement production reached a new all-time high in 2013, according to the annual report “Trends in global CO2 emissions”, released by PBL Netherlands Environmental Assessment Agency and the European Joint Research Centre (JRC). In 2013, global CO 2 emissions grew to the new record of 35.3

The gap, noted the researchers in their open-access paper in Nature Climate Change , is equivalent to Japan’s annual CO 2 emissions, the world’s fourth largest emitter, with 5% of the global total. The dashed line represents the aggregated CO2 emissions calculated from the provincial energy statistics 1997–2010.

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.
