Hi, Bill -- 3 quick points (before I turn my attention to my long list...):
1. I don't know where you are located, but I prefer NOT to use UK resources for U.S. K-12 students because they end up using metric units and that produces another variable making understanding of climate change less accessible for U.S. students. I did notice that you have links to respected sources like NASA and National Geographic -- and that made me think you are on the right track, but do not have time to check all of your links.
2. Having said that, I think the main points you hit are good ones and appreciate your work to reach out to this important audience.
3. For students in middle school and up, I think an important part of climate change education that could be well handled from home is Media Literacy. Kids (and parents) need to work on skills for consuming info in the press and from e-sources. One of the sources that I most respect in this arena is the Stanford History Education Group and their Civic Online Reasoning curriculum. The SHEG curriculum is freely available to all at https://cor.stanford.edu/ But, that may be a separate/next article.

I appreciate your sharing your work and asking for reviews of it ! That's one function of this group that I think is underutilized. If we all took the time to do as you have done, I think we'd all benefit! THANK YOU.
