Summers in Texas Ain't Getting Hotter or Dryer

The release of the latest National Climate Assessment continues to spawn climate hysteria and a whole suite of unwarranted claims regarding the impending climategeddon.

Take this article by Chris Mooney -- author of the New York Times bestselling book The Republican War on Science, wherein Mooney states the following as number two in his "7 Scary Facts About How Global Warming Is Scorching the United States":

"2. That translates into extreme heat where you live. Of course, nobody feels temperature as a national average: We feel it in a particular place. And indeed, we've felt it. The National Climate Assessment makes clear that extreme heat waves are striking more than before, and climate change is involved. Take Texas' extreme heat in the summer of 2011, the 'hottest and driest summer on record' for the state, with temperatures that exceeded 100 degrees for 40 straight days! 'The human contribution to climate change approximately doubled the probability that the heat was record-breaking,' notes the assessment."

Here is the unfortunate point for the alarmists: Texas is not becoming either hotter or drier in the summer.

Using data directly from the horse's mouth (i.e., NOAA/NCDC), between 1895 and 2013, there is no significant trend in June through August, July through September, nor June through September average temperatures in the state of Texas, covering all the bases for how you may want to define summer.

And there are also absolutely no significant trends in summertime precipitation over these three time periods. None. Actually, the correlations are towards more precipitation over time.

Absolutely no correlations over time since 1895 for the statewide summertime drought indices (PDSI and PHDI), either, regardless of how you define summer.

What about monthly extreme maximum temperatures during June through September or the number of days with temperatures reaching or exceeding 100°F? As the table below illustrates for regional stations spread across Texas, no general correlations here either. A few declining trends that balance out the few increasing trends, with the majority of stations showing no trends over record lengths varying from the last few decades up to 120 years.

Perhaps the summertime climategeddon signature is hiding in the trends of July and August average maximum monthly temperatures?

Nope, not here either.

If summertime climategeddon was overtaking the state of Texas due to anthropogenic climate change, we would expect to see widespread and dominant significant increases in summertime average, average maximum, and extreme temperatures, significant declines in summertime precipitation, and significantly worsening summertime drought indices.

We see none of this.
