Letters to the Editor

Stephen Norton: Weather extremes not less severe

The N&O continues to publish letters by climate-change deniers who make questionable claims with no citations. The latest (“Contradicting climate reports,” May 3) stated “According to scientific data from NOAA virtually all extreme weather events (tornadoes, hurricanes, droughts and wildfires) are becoming less frequent and severe.” Show me the citation.

This contradicts hundreds of peer-reviewed publications on this subject. Here are three: “Climate change: Human influence on rainfall,” Nature, Vol. 470, p. 344; “Atmospheric Warming and the Amplification of Precipitation Extremes,” Science 2008: Vol. 321 p. 1,481; “Human contribution to more-intense precipitation extremes,” Nature, Vol. 470, p. 378.

And from the NOAA website, this statement: “Human influences are having an impact on some extreme weather and climate events, according to the report, ‘Explaining Extreme Events of 2012 from a Climate Perspective,’ released today by the Bulletin of the American Meteorological Society. Overall, 18 different research teams from around the world contributed to the peer-reviewed report that examined the causes of 12 extreme events that occurred on five continents and in the Arctic during 2012. Scientists from NOAA served as three of the four lead editors on the report.”

It’s the scientific consensus of university and government climate researchers that deserves the most credibility.
