Dr. Spencer is an internationally recognized climatologist who explains things like why we do not know whether man is causing any climate change or not.

Or, is the planet really warming all over?

  • Summer Causes Climate Change Hysteria
    by Roy W. Spencer, Ph. D. on 2018-07-03 at 14:16

    Summers in the U.S. are hot. They always have been. Some are hotter than others. Speaking as a PhD meteorologist with 40 years experience, this week’s heat wave is nothing special. But judging from the memo released on June 22 by Public Citizen (a $17 million per year liberal/progressive consumer rights advocacy group originally formed […]

  • UAH Global Temperature Update for June, 2018: +0.21 deg. C
    by Roy W. Spencer, Ph. D. on 2018-07-02 at 16:08

    The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2018 was +0.21 deg. C, up a little from the May value of +0.18 deg. C: Some regional LT departures from the 30-year (1981-2010) average for the last 18 months are: YEAR MO GLOBE NHEM. SHEM. TROPIC USA48 ARCTIC AUST 2017 01 +0.33 […]

  • Antarctic Ice Sheet Collapses, Nobel Prizes, and the Psychology of Catastrophism
    by Roy W. Spencer, Ph. D. on 2018-06-17 at 17:02

    Last week I had the privilege of being invited to present a talk at a small conference of world experts in a variety of disciplines. The venue was spectacular, on the French Riviera, and we had an entire late-1800s hotel to ourselves, right on the Mediterranean. For me, it was a once-in-a-lifetime experience. I had […]

  • UAH Global Temperature Update for May, 2018: +0.18 deg. C
    by Roy W. Spencer, Ph. D. on 2018-06-01 at 15:16

    The Version 6.0 global average lower tropospheric temperature (LT) anomaly for May, 2018 was +0.18 deg. C, down a little from the April value of +0.21 deg. C: Some regional LT departures from the 30-year (1981-2010) average for the last 17 months are: YEAR MO GLOBE NHEM. SHEM. TROPIC USA48 ARCTIC AUST 2017 01 +0.33 […]

  • Sea Level Rise: Human Portion is Small
    by Roy W. Spencer, Ph. D. on 2018-05-25 at 16:33

    There is a continuing debate over sea level rise, especially how much will occur in the future. The most annoying part of the news media reporting on the issue is that they imply sea level rise is all the fault of humans. This is why the acceleration of sea level rise is what is usually […]

  • NASA satellite reveals extensive Hawaii SO2 cloud
    by Roy W. Spencer, Ph. D. on 2018-05-22 at 23:05

    The eruption of Kilauea volcano on the Big Island of Hawaii has been unleashing a huge cloud of sulfur dioxide (SO2), which has been showing up in NASA’s Suomi satellite imagery every day. Yesterday, May 21, the cloud is shown here in false color, based upon measurements from the OMPS sensor on that satellite. Carried […]

  • In Defense of the Term “Greenouse Effect”
    by Roy W. Spencer, Ph. D. on 2018-05-09 at 14:03

    Over the years I have gone along with the crowd and derided the term “greenhouse effect” as a poor analogy between the atmosphere’s ability to keep the Earth’s surfce warmer than it would be without IR-absorbing (and thus IR-emitting) gases, versus a greenhouse in which plants are grown. But the more I think about it, […]

  • UAH Global Temperature Update for April, 2018: +0.21 deg. C.
    by Roy W. Spencer, Ph. D. on 2018-05-01 at 14:29

    The Version 6.0 global average lower tropospheric temperature (LT) anomaly for April, 2018 was +0.21 deg. C, down a little from the March value of +0.24 deg. C: Some regional LT departures from the 30-year (1981-2010) average for the last 16 months are: YEAR MO GLOBE NHEM. SHEM. TROPIC USA48 ARCTIC AUST 2017 01 +0.33 […]

  • New Lewis & Curry Study Concludes Climate Sensitivity is Low
    by Roy W. Spencer, Ph. D. on 2018-04-24 at 15:01

    Global warming “problem” cut by 50% As readers here are aware, I don’t usually critique published climate papers unless they are especially important to the climate debate. Too many papers are either not that important, or not that convincing to me. The holy grail of the climate debate is equilibrium climate sensitivity (ECS): just how […]

  • The 100th Meridian Agricultural Scare: Another Example of Media Hype Exceeding Reality
    by Roy W. Spencer, Ph. D. on 2018-04-18 at 15:52

    A new paper published in the AMS Earth Interactions entitled, Whither the 100th Meridian? The Once and Future Physical and Human Geography of America’s Arid-Humid Divide, Part II: The Meridian Moves East, discusses the climate model-expected drying of the western U.S. and how this will affect the agricultural central- and east- U.S. as the climatological […]
