An atmospheric general circulation model you can run on a Python Jupyter notebook?! Heck yeah! Check out this project- both an educational tool for undergraduates/graduate students, and a research tool for scientists interested in idealized climate modeling.

I usually include NOAA NCEI billion-dollar weather/climate disaster figures in my talks. Over the last couple months, I've spent extra time highlighting who makes them and why it's so valuable, including "while we still have this data..." to convey my worry. Sadly I guess my fears were warranted.
