Are you worried you know nothing at all about our environmental problems? Do terms like Greenhouse Gas, Climate Change and the like have you concerned, but you simply don’t understand how basic atmospheres work and how important they are to life? Then check this programme out while you can.

There’s no doom mongering, just pure unadulterated enthusiasm for how our planet’s atmosphere works. In the context of other planets and moons you get a real feel for how special our planet is, and why we should consider, at the very least, what we are doing to it.
