First up on the podcast, we hear from Staff Writer Paul Voosen about the tricky problem of regional climate prediction. Although global climate change models have held up for the most part, predicting what will happen at smaller scales, such as the level of a city, is proving a stubborn challenge. Just increasing the resolution of global models requires intense computing power, so researchers and city planners are looking to other approaches to find out what’s in store for cities.

Next on the show, a visit to Michigan’s Upper Peninsula, where researchers have found evidence that the Indigenous Menominee people cultivated maize for 600 years, even during an ice age. Madeleine McLeester, assistant professor in the department of anthropology at Dartmouth College, talks about using lidar to search among the heavily forested lands for striations that indicate corn farming and the anthropological conundrums raised by such extensive agriculture without nearby urban centers.

Finally in this episode, producer Kevin McLean quizzes host Sarah Crespi on some mysterious sounds that have appeared on the site as part of news stories. No clues here so be sure to play along.

This week’s episode was produced with help from Podigy.
