Texas Drought Not Due to Climate Change, Says NOAA Study

Texas DroughtCredit: Dreamstime - ArtbyallysonLast year Texas suffered through its worst dry spell on record. And lots of folks have been eager to suggest that it was at least exacerbated by climate change. Oh, the irony of a state proud of its oil production being laid low by the very climate its iconic crude disrupts. A new report by researchers at the National Oceanic and Atmospheric Administration has concluded that that's not so. From the AP:

Last year's huge drought was a freak of nature that wasn't caused by man-made global warming, a new federal science study finds.

Scientists say the lack of moisture usually pushed up from the Gulf of Mexico was the main reason for the drought in the nation's midsection.

Thursday's report by dozens of scientists from five different federal agencies looked into why forecasters didn't see the drought coming. The researchers concluded that it was so unusual and unpredictable that it couldn't have been forecast.

"This is one of those events that comes along once every couple hundreds of years," said lead author Martin Hoerling, a research meteorologist at the National Oceanic and Atmospheric Administration. "Climate change was not a significant part, if any, of the event."

Researchers focused on six states - Wyoming, Kansas, Nebraska, Colorado, Missouri and Iowa - but the drought spread much farther and eventually included nearly two-thirds of the Lower 48 states. For the six states, the drought was the worst four-month period for lack of rainfall since records started being kept in 1895, Hoerling said.

He said the jet stream that draws moisture north from the Gulf was stuck unusually north in Canada.

Other scientists have linked recent changes in the jet stream to shrinking Arctic sea ice, but Hoerling and study co-author Richard Seager of Columbia University said those global warming connections are not valid.

Hoerling used computer simulations to see if he could replicate the drought using man-made global warming conditions. He couldn't. So that means it was a random event, he said.

The study was titled, "An Interpretation of the Origins of the 2012 Central Great Plains Drought," but when it comes to climate, you can be sure that there are always other conflicting "interpretations." The folks over at the left-leaning ThinkProgress blog cite a furious push back against the conclusion of the NOAA study by National Center for Atmospheric Research climatologist Kevin Trenberth. Among other criticisms, Trenberth notes:

In the experiments performed with climate models, no indication is given that the model used or the forecast results from several other models, have any skill or utility at the task set them. The distinctive La Niña pattern in 2011 giving extremes of dryness in Texas and wetness further north was not simulated or predicted either! In the lower 48, it has been distinctly wetter after about the 1970s in all seasons other than winter, but none of the models simulate this. Not one! The model biases are not dealt with and their skill, or lack of it, is not given. They are not shown to be appropriate to the task at hand. There is a complete failure to provide any reasons to believe the results. Moreover the experiments are woefully incomplete. SSTs [sea surface temperatures] were specified but no attempt was made to include soil moisture, snow cover anomalies, or vegetation health, for instance.

Models, models everywhere, and not a drop to drink (at least not in Texas).

    That's a damned lie. The drought was a change from the earlier, not droughtiness, and a drought is a climate activity; therefore, climate change. Johnny, what do I win?

    Dry humor!

    It seems about as silly to claim that an event is not cause by climate change as it is to claim that something definitely is. It seems to me that if climate changes, those changes will affect everything to some extent. In a very complex system, everything is really caused by everything.

    and isn't that the rational point - climate changes because that's what it does. That, of course, is not enough for the warmist crowd; it will insist that change is man's fault and only govt can prevent further damage. But then, the warmists don't much care about climate or the planet, just their ability to control people's lives.

    I'm not sure who coined the phrase "natural climate change denialism" to describe the cult's retreat to "so what if our models are wrong, natural variability can't explain what's going on, and if you don't have a mechanism, STFU", but that person definitely nailed what's going on.

    It's amazing how much of the CAGW cult's pronouncements are textbook examples of projection.

    "Yeah, that was me back in 92. I coined that phrase. You can just give me credit from here on out."

    Experiments performed with climate models?!?

    A climate model is a giant calculation, not qualitatively different than the time I sat down to use calculus, thermo and kinematic to predict the muzzle velocity of a bullet given different types of gas expansion.

    It's a thought experiment, but doesn't prove anything. A real experiment is when you make observations generally with the intention of testing a theory by seeing if the observations will show it to be false.

    I'm not sure how climatology came to be dominated by such a dominatingly invasive crop of pseudo-scientists who confuse theory with experiment, but I think some science historian will definitely do the world a favor when, after the ashes have settled & the ardor cooled, the historian publishes a definitive history of how the mess came to be.

    A new federal science study BOUGHT AND PAID FOR BY BIG OIL TAXES, YOU MEAN.

  • Tony||

    ...that you should immediately discard as completely wrong because it was funded by government and relied on computer models, you mean.

  • DaveAnthony||

    What's this? Climate models can't predict actual outcomes? Does the pro-AGW crowd really want to advocate for this argument?

  • Ron Bailey||

    DA: ^This^

    I KNEW it was the Canuck's fault.

    You bastards!

    *shakes fist*

  • Sevo||

    Blame it on Canada...

    Everybody was claiming it was going to be a 5-10 year drought. And it's already recovering, nice call alarmists.

    Last summer was a bitch though.

    Sounds like a rock solid plan to me man, I like iot.

    What else is new , Ron ?
