The Climate Change Factor in Extreme Weather Events

The 4 Mile Creek area near Boulder, Colorado, was devastated by an extreme rain/flood event in September 2013.

An op-ed in today’s New York Times, How We Know It Was Climate Change,  is well worth reading. The author of the op-ed, N.S. Diffenbaugh, lays out the rationale for a link between climate change and extreme weather events. Diffenbaugh’s op-ed is based on a journal article written by himself and others that was published in the Proceedings of the National Academy of Sciences (PNAS – 3/17), Quantifying the influence of global warming on unprecedented extreme climate events.

Both the op-ed and the PNAS article are essential reads for the new year.
