interfluidity, subscribed podcasts

In this week’s episode, host Daniel Raimi talks with Jonathan Jennings, a meteorologist at the Utah Division of Water Resources and president of the Weather Modification Association. Jennings’s work focuses on cloud seeding, a technology that can reduce hail and increase rainfall or snowfall by introducing chemicals into clouds, yielding more water for agriculture, aquifers, and bodies of water. Jennings outlines the chemistry and physics behind cloud seeding, how much additional precipitation the technology can elicit from clouds, and the scale at which cloud seeding is used. He also speaks to public concerns about modifying weather and shares insights on how experts can better communicate the goals, methods, and impacts of this technology to the public.
