I think most of us understand “The Greenhouse” effect at a middle school level. The problem is, it is easy to punch holes through the model at that level. Some minority understand it at a high school/college freshman physics level. Much better, but still a few issues, which climate change deniers have been schooled to point out, even those who don’t know physics at a middle school level.
Sabine Hossenfelder has a YouTube channel, “Science without the Gobbledygook” where she explains relatively advanced topics in an easy to understand fashion. Recently she took up this topic. See here:
A big take away, perhaps the most important point, is that we know the current warming is due to the greenhouse effect (human activity) because of something called “Stratospheric Cooling”. Super simply put, as green house gases go into the atmosphere, the stratosphere will cool while the areas around ground level (she didn’t say, but I will say in the troposphere, but it may be even closer to the ground than that…) will warm up. That is what we are seeing. If the sun releases more energy and heats us up, we don’t see it. As I said, we do, so…
Anyway, I found this video interesting and think it is one of those that everyone needs to see.
