The Age of Man?
Geologists are saying we're living in new times - so new that they're thinking of changing the name of the geological phase in which we live. The notion recognises humans as the driving force behind changes to the planet which is why the new epoch has been dubbed Anthropocene, or the Age of Man.
This week, we head to Grenoble in France where glaciologists have been recording evidence of increasing CO2 levels in the the atmosphere. Man's interference in the carbon cycle has been blamed for global warming, a phenomenon which could lead to permanent changes in the earth's strata.
Next, we head to the heart of the Arctic where scientists are researching the effects of ocean acidification. The resulting loss of biodiversity is seen as further proof of man's irreversible footprint.
And finally, we look at how one might survive in the new epoch. Followers of the Mayan calendar believe the world will end next year. They're among thousands of people investing in post-apocalyptic bunkers that can accommodate one thousand people underground for up to a year.
