Raised Beaches Podcast
The Raised Beaches Podcast is a discussion on topics related to paleoclimate, Earth Science and global change. Dr. Evan J. Gowan highlights the concepts and underlying evidence on how climate, sea level and the Earth surface changes through time. He also connects how our knowledge of the past informs our predictions of future climate.

I discuss about how autumn is late coming to Japan, and my geological observations from my recent trip to Nagasaki. I talk about the devastating hurricanes in the southeastern United States, and how Hurricane Helene affected the National Centers for Environmental Information (NCEI). I discuss a newly published paper on the rate of sea level rise. Finally, I introduce the Global Self-consistent, Hierarchical, High-resolution Geography Database, and some of the issues I have had with it.
