Old Atmosphere Returns

Much of the US was enjoying Jeff Master’s “whole new atmosphere” for a few weeks, but the old atmosphere has returned and it is cold and wet again.

    How was it determined 2011 was Texas’ worst drought for a single year? What was the closest year?

    See 1930s, 1950s, 1988 for comparison: http://www.ncdc.noaa.gov/temp-and-precip/drought/historical-palmers.php Highlight the months you want in blue, type in the range of years, and you get a nice slide show.

    Here they changed the methodology, with data only going back to 2002: http://www.ncdc.noaa.gov/temp-and-precip/drought/nadm/nadm-maps.php

    Those who claimed 2011 in Texas was the worst year ever cherry-picked their data and methodology instead of looking at a big picture of a hundred years of data (which in and of itself is a tiny fraction of the geological record).

    If you go to the Texas precipitation page
    http://www.ncdc.noaa.gov/oa/climate/research/cag3/tx.html
    and create a chart of annual precipitation, you’ll see that the drought for 2011 in Tx was quite similar to the droughts in about 1957 and 1918. Tx precip is highly variable. As you know drought/flood is a sure sign of global warming, so Tx is a perfect example of the havoc that “bad man” can have on the climate. drought/flood can really be catastrophic. it’s really terrible what has happened with that drought/flood.
