Big Picture Lessons from an Unfortunate Tweet

Just in case someone asks, No, there is not enough rotation and scale to produce the Coriolis Effect by spinning the Wheel of Fortune.

Now that we have clarified that, I wanted to use the recent Pat Sajak tweet to turn a negative to a positive.  I don’t know Mr. Sajak so will not judge him, his intent, or ideological perspective. Instead, I will draw out 3 things that can help advance the discourse on climate science.

First, it is imperative for the public to recognize that this “minor” incident highlights a “major” problem. All kinds of people with virtually no expertise are comfortable speaking on climate science. I can be in the grocery store and if someone finds out that I am a meteorologist-climatologist type, they often feel comfortable telling me “the climate changes naturally” or launching into some zombie theory (i.e. a theory that I have heard a million times and has been disproven by the science). I am usually cordial, but in the back of my mind, I am thinking “really? You think the Director of a major university's atmospheric sciences program (Go Dawgs) with a BS, MS, and PHD in meteorology from a top program (Go Noles) doesn’t know that the climate changes naturally?”

I often wonder if nuclear engineers experience people walking up to them in the mall suggesting new reactor cooling techniques. But, I digress. Meteorology is rooted in fluid dynamics, thermodynamics, and other complex mathematics-physics principles. It has been rated, many times, as one of the most difficult majors on a college campus. I often have students coming to my program wanting to study weather or climate because they “love clouds or tornadoes,” yet when I lay out the math, physics, and other requirements, they have a "deer-in-headlights" look.  For more information on the credentials required to be a meteorologist, visit I think even this curriculum could be augmented because many programs are very limited in coursework related to climate modeling, paleoclimate studies, advanced time series analysis, and advanced statistical methods.

The lesson here is that you must consume information from credible or expert sources.  Ask yourself if the author of that blog or Op-Ed has a background in the science, has published in peer-reviewed journals, or at least put forth their position in a forum that can evaluated, tested, or scrutinized.  Additionally, it is important to remember that just because people have “equal access” to experts in formats like Twitter, it doesn’t mean “equal expertise.” My 7 year old could tweet his view on the onset of El Nino, but it doesn’t mean it is credible.

Second, the public must understand that just because you know a TV personality, it doesn’t signify that they are an expert on climate or vaccines. While this may sound trivial, many celebrities reach millions of people, and I am convinced that some fall lock step with their viewpoint just because they like them or their show. Likewise, it is important to remember that “weather is your mood, climate is your personality.” Expertise in day-to-day weather forecasting is not necessarily expertise in climate analysis, modeling, and processes.

Every now and then, I get the question, “So how can we trust a climate model in the year 2040, if a weather model is not good beyond 7-10 days?”  That question immediately tells me there is a gap in background because climate models are not predicting the exact state of the atmosphere (weather) on Wednesday in 2040. It is an apples and oranges discussion. More disturbingly, I have received that question from a few people that reach the public every day.

Having said that, there are a ton of outstanding colleagues in the broadcast world that do an amazing job with weather and climate.

Finally, irrespective of viewpoint, the name-calling and bullying must stop. We are not 5th graders. Scientists are trained to disagree and have scientific discourse without taking it personally.   There are colleagues that I fundamentally disagree with on aspects of this issue yet still respect them and interact with them in a professional, social and respectful manner.

“Unpatriotic racists?” ….I clearly serve my country and have yet to figure out how to discriminate against myself or anyone else.  I am an African-American scientist. I am the immediate Past President of the largest professional society in this country associated with weather and climate (AMS). I served on a Pentagon-commissioned study on climate and national security. I was a NASA scientist for 12 years. I currently serve on advisory boards for NOAA and NASA, respectively.

Meanwhile, I am curious to see if I can use the “Wheel” to teach anything about vorticity, force, or shear in a future meteorology class :)
