Roy Spencer: Summer Causes Climate Change Hysteria

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.

Roy Spencer: Antarctic Ice Sheet Collapses, Nobel Prizes, and the Psychology of Catastrophism

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

Roy Spencer: Sea Level Rise: Human Portion is Small

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

Roy Spencer: NASA satellite reveals extensive Hawaii SO2 cloud

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

Roy Spencer: In Defense of the Term “Greenouse Effect”

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,

Roy Spencer: New Lewis & Curry Study Concludes Climate Sensitivity is Low

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

Roy Spencer: Midwest’s April chill most unusual on Earth

If you thought the cold April weather in the U.S. was exceptional, you are correct. In terms of temperature departures from average so far this April, the U.S. Midwest, Northern Plains, and much of Canada have been the coldest on Earth (graphic courtesy of Weatherbell.com): The areas of green have averaged at least 6 deg.
