In grad school I pursued (at the time it was considered experimental) a minor in "Sustainability Management". This was like 10 years ago and there was nowhere near the amount of stuff happening in the space then as there is now - it was basically "how do we get corporations to reduce their emissions? LOL good luck" and "how do large scale renewable energy projects make it? Only gonna happen with government help". I was a little disappointed with it at the time but I'm really happy that the field has awoken and that tech is getting involved - I would love to see how "higher" education in that space has changed.
> What do your do with a degree in climatology?
I write code, ironically. I'm in the camp that believes degrees aren't _totally_ about what you learn but more about advancing your reasoning and thinking skills and learning how to interact with people (not to say you don't learn anything in school, you definitely do but IMHO it largely depends on what you study).
