Didn't see the program so it would be worthwhile checking it out.
Once-upon-a-time volcanoes were a major part of changing the atmosphere on the earth. However the current volcanic activity is only a tiny proportion of what people current emit through cars, power stations agriculture ect. See reference below.
As far a global warming causing greater volcanic activity. The argument goes that as the ice melted from teh last Ice Age the release of weight on the earth allowed movement in tectonic plates which then caused earthquakes and volcanoes. In theory further loss of ice will cause similar events.
