You could almost set your watch by it. It has become a regular absurdity that a bunch of non-scientists try to tell the world that they know something the experts don’t.
Those of us who watched that iconic television show called Cheers remember Cliff, the mailman. He considered himself the expert on everything even though it was painfully obvious he knew very little about anything.
Well we got our latest batch of Cliff Clavin wisdom this past week when 49 former staff members from NASA wrote a letter to NASA administrators decrying the work that the organization does on climate. It makes one wonder what the thousands of current NASA employees think of their former colleagues.
It is important to point out that the leader of this gang is none other than Harrison Schmitt, a well-known, and self-described “denier” of human-caused climate change. While he trumpets his scientific expertise, none of it relates to climate.
For those who follow the more extreme fringes of climate denialism, Harrison’s participation is not a surprise. Approximately one year ago he claimed the arctic sea ice had recovered from its dramatic declines in preceding years. That claim was false and it attracted the attention of the National Snow and Ice Data Center who had to tell us what we already knew… Harrison Schmitt didn’t know what he was talking about.
Also not surprising to real climate scientists is that the other person who apparently spearheaded this letter, Walter Cunningham, has zero climate experience.
But there must be someone in the group who knows of what they speak, right? Probably not. I performed a scientific literature search on over half the signers and found, you guessed it, zero experience. So, this is a group that might be able to build spacecraft, but they certainly aren’t a group with notable climate backgrounds.
So why the charade? While I cannot be certain, I can only guess. Perhaps, in the era of tight science budgets, this group bemoans the money spent on Earth sciences when it could be spent on manned spaceflight. I am also guessing that the denialists have run out of real scientists to speak for their cause. The small and decreasing cadre of denialist climate scientists have had a few bad years. We have had continued increases in the Earth’s temperature, extraordinary weather that has made people in states like Texas, Oklahoma, and North Dakota wonder what was happening, and increasing costs of severe weather including droughts and massive, repeated flooding.
The few second-rate scientists who used to tell us “don’t worry, this is all natural” have now mainly had their work shown to be faulty or have seemingly given up on publishing altogether. Now over 97% of experts in this field agree, humans are changing the climate. So, the denialist camp has now turned to their third-string lineup.
I’m just glad that I know some of the hard working scientists at NASA who spend long hours studying our Earth, helping us make wise decisions to protect this beautiful and bountiful planet for our future generations. It is those people and the uncountable real scientists and engineers who are working every day to solidify our understanding of the climate and help bring clean technologies to market that will not only save our environment but also create jobs, improve national security and truly diversify our energy supply.
