Bill Nye “the Science Guy” is a mechanical engineer with a bachelor’s degree who claims to know everything there is to know about climate change. He has previously said that climate change skeptics deserve to be in jail, and has declared that 100 percent of climate change is caused by humans. And this weekend, Nye berated CNN for having a physicist on the air. Not just any physicist, but an award-winning professor of physics at Princeton University who served at the U.S. Department of Energy. So apparently you’re only a scientist if you subscribe to Nye’s worldview on climate change. But calling the March for Science a positive thing after slamming this physicist is too much! If you really believe in science, you have to accept the scientific method and discovery, and you can’t pretend to be a know-it-all.
