I was so tempted to headline this post with the res ipsa loquitur tag, but didn’t at the last minute. The reason: I was convinced that as obvious as the scientific and logical nonsense her tweet represented should be, a lot of usually intelligent people wouldn’t allow themselves to see it, because, as Ethics Alarms notes repeatedly, “bias makes you stupid.” The post’s comments turned out to be a marvelous example of that.
One persistent defender of Omar insisted that it was crucial that I had checked the alleged authority for her gaffe before criticizing her. It happens that I did, but I didn’t need to. Nobody did: that’s the whole point. If the woman had the requisite number of brain cells to rub together to start a bonfire, she would have known what emerged from her keyboard when she typed that was hilariously silly with the application of basic critical thinking skills.
Recently, Major League Baseball teams broke the record for the most runs scored in all games on a single day. It was remarkable, because the record was more than a century old: the day occurred in the 19th century. All of the articles about this event specified the day. If, as Omar’s ignorant tweet claimed, the Earth had broken its previous record for “hottest day in 120,000 years,” there would be a day from 120,000 years ago that held the broken record. No source mentioned such a day, however, because there are no daily records of the Earth’s weather—daily temperature is weather, not climate—from 120,000 years ago or even a thousand years ago (though we know Pompeii got pretty damn hot when Mt. Vesuvius erupted in 79 AD.) Estimates of global climate in the periods before records were kept depend on “proxy data.” Here is a chart explaining what proxy data can tell scientist about distant climates:
