So, first of all, this ignoramus has an aptly abbreviated "BS" in meteorology. Namely, he's an Art Garfunkel of science. He is to science what Nickleback is to rock music.
Mostly, this is a dude who is afraid of dissent. He's using his piss-ant degree as an excuse to put down people who disagree with him. The people sharing this -- unironically and/or without criticism -- are just appealing to a weak appeal to authority to avoid debate.
To agree with a scientist about science is to disagree with another scientist about science.
When cholera broke out, the majority of what would be currently known as scientists at the time thought that it was an airborne virus. It took a man breaking quarantine and surveying the population to determine that it was in the water. He disagreed with the majority of "scientists" at the time, and he was right.
Yes, good scientists change their minds when the evidence changes -- that's why Anthony Fauci isn't a scientist. This is why this congressman isn't a scientist for simply having a piece of paper that says that he spent a certain amount of money to get a degree in the junior varsity version of climatology.
Every person of every discipline should be open to disagreement and new ideas from anybody.
