Rising Carbon Dioxide

The World Meteorological Organization reports that the atmospheric carbon dioxide concentration averaged 396 parts per million in 2013.  The increase from 2012 to 2013 was the largest in nearly 30 years.  That seems to be due to not only greater emissions, but also reduced uptake in the biosphere.

Update (September 13):  More on the disruption of the carbon cycle.


Update (November 9, 2015):  The World Meteorological Organization says that the atmospheric carbon dioxide concentration averaged 397.7 parts per million in 2014.
