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?

  • Total Lunar Eclipse Time Lapse, January 20-21, 2019
    by Roy W. Spencer, Ph. D. on 2019-01-21 at 21:44

    I’ve been wanting to do this kind of time lapse of a lunar eclipse to show just how much change in brightness occurs when the full moon suddenly becomes nearly dark. Most presentations of a lunar eclipse don’t really capture the darkening, just the change in color as the moon transitions from being illuminated by […]

  • Tomorrow’s Total Lunar Eclipse, and a Mystery
    by Roy W. Spencer, Ph. D. on 2019-01-19 at 14:26

    Tomorrow night (January 20-21) will present the whole U.S. with a total lunar eclipse, the best one until May 15, 2022. Totality here in Alabama will occur approximately from 10:40 to 11:40 p.m. CST. Clear weather will be restricted mostly to the southeastern U.S., and portions of the Northern Plains and Great Lakes: A Mystery […]

  • Ocean Warming in Climate Models Varies Far More than Recent Study Suggests
    by Roy W. Spencer, Ph. D. on 2019-01-17 at 18:58

    I wanted to expand upon something that was mentioned in yesterday’s blog post about the recent Cheng et al. paper which was widely reported with headlines suggesting a newer estimate of the rate of ocean warming is 40% higher than old estimates from the IPCC AR5 report in 2013. I demonstrated that the new dataset […]

  • Media Reports of +40% Adjustment in Ocean Warming Were Greatly Exaggerated
    by Roy W. Spencer, Ph. D. on 2019-01-16 at 16:41

    Summary: The recently reported upward adjustment in the 1971-2010 Ocean Heat Content (OHC) increase compared to the last official estimate from the IPCC is actually 11%, not 40%. The 40% increase turns out to be relative to the average of various OHC estimates the IPCC addressed in their 2013 report, most of which were rejected. […]

  • Chuck Todd Devotes an Hour to Attacking a Strawman
    by Roy W. Spencer, Ph. D. on 2019-01-03 at 15:18

    or, All Credentialed Journalists are Sex Abusers Chuck Todd, on a recent episode of Meet the Press, highlighted the issue of global warming and climate change. He unapologetically made it clear that he wasn’t interested in hearing from people on the opposing side of the scientific issue, stating: “We’re not going to debate climate change, […]

  • UAH Global Temperature Update for December 2018: +0.25 deg. C
    by Roy W. Spencer, Ph. D. on 2019-01-02 at 13:50

    2018 was 6th Warmest Year Globally of Last 40 Years The Version 6.0 global average lower tropospheric temperature (LT) anomaly for December, 2018 was +0.25 deg. C, down a little from +0.28 deg. C in November: Various regional LT departures from the 30-year (1981-2010) average for the last 24 months are: YEAR MO GLOBE NHEM. […]

  • Government Shutdown Delays UAH Global Temperature Update
    by Roy W. Spencer, Ph. D. on 2019-01-01 at 12:29

    The NOAA CLASS system we obtain our satellite orbit files (raw data) from has been taken offline until the government shutdown ends. As a result, our UAH monthly global temperature update is delayed. UPDATE: We have a separate data feed and so I’ll be able to post results tomorrow, Jan. 2. […]

  • Giving Credit to Willis Eschenbach
    by Roy W. Spencer, Ph. D. on 2018-12-31 at 14:08

    The non-greenhouse theory of Nikolov (and now Zeller-Nikolov) continues to live on, most recently in this article I’ve been asked about on social media. In short, it is the theory that there really isn’t a so-called “greenhouse effect”, and that the excess planetary surface temperatures on Earth, Venus, and other planets above the Stefan-Boltzmann (SB) […]

  • 2018 6th Warmest Year Globally of Last 40
    by Roy W. Spencer, Ph. D. on 2018-12-20 at 18:03

    Even before our December numbers are in, we can now say that 2018 will be the 6th warmest year in the UAH satellite measurements of global-average lower atmospheric temperatures, at +0.23 deg. C (+0.41 deg. F) above the thirty-year (1981-2010) average. (Jan. 2, 2019 update confirms this.) The following plot ranks all of the years […]

  • The Five Questions Global Warming Policy Must Answer
    by Roy W. Spencer, Ph. D. on 2018-12-18 at 15:49

    It is no secret that I doubt increasing CO2 in the atmosphere will have enough negative effects on the global environment to warrant the extreme cost to humanity of substantially reducing those effects. Note that this statement has both science and energy policy components. In fact, with “global greening” we should consider the possibility of […]
