It Isn't Settled

So says Richard Lindzen, Professor of Meteorology at the Massachusetts Institute of Technology, recipient of the American Meteorological Society's Meisinger and Charney Awards, and a member of the National Academy of Sciences.


Claims that climate change is accelerating are bizarre. There is general support for the assertion that GATA has increased about 1.5 degrees Fahrenheit since the middle of the 19th century. The quality of the data is poor, though, and because the changes are small, it is easy to nudge such data a few tenths of a degree in any direction. Several of the emails from the University of East Anglia's Climate Research Unit (CRU) that have caused such a public ruckus dealt with how to do this so as to maximize apparent changes.


...the main greenhouse substances in the earth's atmosphere are water vapor and high clouds. Let's refer to these as major greenhouse substances to distinguish them from the anthropogenic minor substances. Even a doubling of CO2 would only upset the original balance between incoming and outgoing radiation by about 2%.

Confident predictions of catastrophe are unwarranted

    True, but beside the point.
