I just started listening to podcasts last summer, but one I like is Extremities. It's three seasons now and they're all about remote islands. Svalbard, Pitcairn and St. Helena. Svalbard is probably the most interesting because it's an international zone.

I think 31 Thoughts is still going. If you can handle Marek and Eliotte's false modesty and smugness.
