Cloud-dwelling Bacteria, & Ozone Holes


Chris Smith

Catherine Hawkins

In today's show, we discuss the weather, climate change, and the hole in the ozone layer. From the University of East London Drs. Tom Hill and Bruce Moffett discuss how they have discovered cloud-living bacteria that could be responsible for triggering rainfall, and Dr. Brian Gardiner, from the British Antarctic Survey (BAS) describes how he and 2 colleagues first discovered the ozone hole in the mid 1980's, why it forms in Antarctica, and how CFCs contribute to ozone-depletion. Also, Rosemary joins us to talk about the benefits of Aloe Vera, and space scientist Dr. Julian Osbourne drops in to tell us about the launch of Swift, a satellite intended to look for gamma-ray bursts (GRBs).
