Would a Weather and Climate Change class be helpful to peruse a career in environmental economics I’m an undergraduate student and want to become an environmental economist. Would it be beneficial to take a class on weather and climate change or should I stick with economics courses geared towards the environment?
It wouldn't be detrimental by any means, but I would regard it as non-essential.

non-essential, because you'll likely use quite a simplified (as opposed to simple) framework for thinking about interactions between the economy and the environment. See for example Golosov et al. (2011) https://www.nber.org/papers/w17348

and non-essential because the larger models with more complex interactions between the economy and the climate/weather systems, would normally be conducted alongside some climate scientists. The division of labour here is arguably preferable, given that climate scientists and economists bring their own respective strengths to the table. I believe this to be the case in some of the integrated assessment models (IAMs) such as RICE/DICE etc.


But overall, if you believe it to be beneficial to your cause; I don't think it would be detrimental. Certainly it would enrich any modelling you'd consider doing.
