It’s been a good few years for audio. From the massive success of public radio podcasts like Serial and Invisibilia to the rise of for-profit podcasting networks like Radiotopia and Gimlet, talk is no longer solely the purview of NPR nerds and shock jocks. Everyone, it seems, loves podcasts. Us, too. Here are a few of our favorite podcast episodes of the year:

This whole series is worth listening to, but start here for the backstory to the Guardian’s hugely important coverage of climate change in advance of the Paris climate talks.
