That is the insidious nature of being uneducated or ignorant in a heavy science subject. I'm fairly well educated, and had a meteorological related job for many years, and I still have a hard time parsing many of these papers. So my options are:

A. Spend huge amounts of time learning the heavy math involved

B. Find someone else who seems educated enough, and trust their ELI5

C. Make my own conclusions based on an imperfect understanding of the science

D. Make my own conclusions based on experience and whatever knowledge I have at the moment

Now I do understand enough about atmospheric dynamics to know, at a high level, that human induced climate change is occuring, why it's happening, and some fuzzy understanding of some of the effects we will see. But I don't think a generic USA highschool level education will be able to inform people enough to have the same understanding, which is why we are in this boat. It seems mostly the people who really understand the what/when/why/how of the situation are STEM field graduates.
