California’s drying up but Dave and Ol’s pun juices are flowing freely. The results aren’t pretty.

Plus, aviation industry 'babble, undeterred seals, and annoyingly time-sensitive predictions.

Sustainababble is a weekly podcast for and by greeny types who don’t really know what’s going on. It comes out every Monday.

Music by Dicky Moore from Bearcraft.

Available on iTunes, Stitcher, Soundcloud, and on the sustainababble website. Visit us at @thebabblewagon and at Facebook.com/sustainababble
