DESCRIPTION

Geoengineering is a very real endeavour in today's climate-change driven world. Steve and Ben discuss its implications, as well as a rogue science project in Canada that saw iron dust dropped in to the Pacific Ocean to help marine life. The guys also discuss: terraforming as depicted in Star Trek III and Total Recall, new discoveries by the Mars Rover, and the 61-year WITCH computer roars back to life thanks to a restoration project undertaken by a museum in the UK.
