The weather here is so unfathomable.

That was definitely one of the better Nova episodes (Kenney, I'm assuming you watched it online!). Around the twenty minute mark, there was quite a bit about Mauna Loa and its importance in climate research including some nice photography of the place. Overall, it covered just about everything including towards the end stuff I was unaware of, e.g., no-till farming.
