The USDA’s Southwest Regional Climate Hub has a new online curriculum on agriculture and climate change available for K-12 educators and students.  I haven’t had a chance to look at it yet, but even though it was written for the Southwest, I’m sure it contains information that would be valuable to the Southeast as well. You can get it for free, just need to do a quick registration so they can track who is using it.  See more at  https://swclimatehub.info/education/climate-change-and-agriculture.
