WTP 120: The PC Turns 25, Artic Seed Bank, Siberian Permafrost, Australian Climate Views, Green Tea

A birthday celebration: looking back at 25 years of the personal computer. A bank filled with seeds buried deep in the Artic. Permafrost melts in Siberia. A conversation from Australia: the stance on climate change from Down Under. And the benefits of green tea? And your letters, along with the magical sounds of the one and only Alex Gallafent on keyboard, drums, trumpet and guitar.
