The science is actually pretty straightforward, I taught it to my nephew because it’s a great way to understand thermodynamics, conservation of energy and a few other fundamentals.

I’m not talking about crunching numbers to calculate the total CO2 equivalent in the air or to model an ice shelf or to quantify the AMOC or something, but the fundamental issue and why it happens is easy enough to understand for the layman.

There’s a great video of Carl Sagan addressing congress(?) about climate change where he explains it concisely, if you’re interested.
