NASA: Increasing Carbon Emissions Risk Megadroughts

An anonymous reader writes: Droughts in the western U.S. have been bad recently, but not as bad as they could be. Researchers from NASA, Cornell, and Columbia are now warning that if we don't slow the rate at which we produce greenhouse gases, then we're dramatically increasing our odds of a drought that lasts upwards of three decades. "The scientists were interested in megadroughts that took place between 1100 and 1300 in North America. These medieval-period droughts, on a year-to-year basis, were no worse than droughts seen in the recent past. But they lasted, in some cases, 30 to 50 years. When these past megadroughts are compared side-by-side with computer model projections of the 21st century, both the moderate and business-as-usual emissions scenarios are drier, and the risk of droughts lasting 30 years or longer increases significantly."

    These AGW stories keep getting more pathetic as time goes by. I don't remember a year as wet as this one in 30 years.

    That seems.. a somewhat less scientific method of reaching a conclusion than the methods climatologists use to reach theirs.

    That's an appeal to authority argument PopeRatzo.

    Your parents should have read to you the fable of the Emperor's New Clothes.

    And your arguments seem to be based on appealing to yourself as an authority; e.g. your claim that you "know Earth history and geology well to know that AGW is bunk".

    I find PopeRatzo's appeal to legitimate expertise much more compelling.

    Yes. Obscuring measurements by lying with statistics is more scientific.

    If you genuinely believe this whole AGW thing is a global conspiracy and that only enlightened ones who can see through the lies (such as yourself) can save us from the deception, then I'll make sure I never waste my time engaging you in conversation again.
