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?

  • L.A. Wildfires Creating Spectacular Smoke Plume
    by Roy W. Spencer, Ph. D. on 2017-12-07 at 12:48

    The warm, dry Santa Ana winds which are fanning the flames of the wildfires in the L.A. area have pushed the smoke hundreds of miles offshore. Yesterday’s NASA MODIS imager on the Terra satellite captured the following image of the smoke being sheared into artistic shapes as it travels downwind. Click on the image for […]

  • Mysterious Night Flashes Near Mt. Agung Volcano Observed from Satellite
    by Roy W. Spencer, Ph. D. on 2017-11-27 at 22:47

    Today I was watching the 10-minute imagery from the Japanese Himawari geostationary weather satellite for the next eruption of Mt. Agung in Bali, Indonesia, and in the last hour or so there have been some distinct flashes in the nighttime imagery, which you can access here. These only show up in the nighttime imagery. UPDATE: […]

  • Trump Wrongly Blamed for Destroying Sea Ice Satellite

    No, Our Ability to Monitor Sea Ice Has Not Ended Yesterday, The Guardian ran a story with the headlines: Donald Trump accused of obstructing satellite research into climate change Republican-controlled Congress ordered destruction of vital sea-ice probe But as NASA’s leader of the U.S. Science Team on one of the best satellite instruments developed for […]

  • The Monty Hall Problem: There Is No Correct Answer
    by Roy W. Spencer, Ph. D. on 2017-10-01 at 11:57

    A diversion from global warming topics. The simple little probability problem below has apparently been debated for many years. It came to prominence when Marilyn vos Savant answered a reader’s question about it. Her answer was believed to be wrong by some of the greatest statistical minds in the world, and eventually most of them […]

  • The 11-Year Major Hurricane Drought: Much More Unusual than Two Cat 4 Strikes
    by Roy W. Spencer, Ph. D. on 2017-09-21 at 13:37

    Weather.com published an article noting that the two Cat 4 hurricane strikes this year (Harvey and Irma) is a new record. Here’s a nice graphic they used showing both storms at landfall. But the statistics of rare events (like hurricanes) are not very well behaved. Let’s look at this new record, and compared it to […]

  • Cracks in the Empire’s Armor Appear
    by Roy W. Spencer, Ph. D. on 2017-09-20 at 10:54

    Yesterday brought widespread news coverage of a new “study” published in Nature Geoscience which concludes that global warming has not been progressing as fast as expected, and that climate models might be a “little bit” wrong. (That the “little bit” is a factor of 2 or 3 is a fine point upon which we won’t […]

  • Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming
    by Roy W. Spencer, Ph. D. on 2017-09-18 at 22:45

    Partly in response to the crazy claims of the usual global warming experts (Stevie Wonder, Beyoncé, Jennifer Lawrence, Mark Ruffalo, Bill Nye the Science Guy, Neil deGrasse Tyson, Pope Francis), I decided to write another Kindle e-book. This one is entitled, Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming. In it I review […]
