Science In Action - Heat death by volcano and other stories

Science in Action this week comes from a vast gathering of earth scientists in Vienna, at the general assembly of the European Geosciences Union.

Roland Pease hears the latest insights into the cataclysmic eruption of Hunga Tonga in the Pacific ocean from volcanologist Shane Cronin of the University of Auckland.

He also talks to NASA's Michael Way about how the planet Venus might have acquired its hellish super-greenhouse atmosphere, and how the same thing could happen to planet Earth.

There’s intriguing research from geologist John Tarduno of the University of Rochester that hints of a link between the ups and downs of the Earth’s magnetic field and the evolutionary history of animals.

Fraser Lott of the UK's Hadley Centre explains his ideas for calculating an individual person's responsibility for climate change-driven extreme weather events.
