A new documentary from the BBC foretells a disaster waiting to happen in "Earth Under Water."
Imagine sea levels rising to over 70 metres... Eminent climatologists think another Great Flood is inevitable if current CO2 emissions continue. Based on research by NASA astro-biologist and paleontologist Professor Peter Ward and a group of respected American climatologists, Earth Under Water is an eye-opening documentary uses scientific evidence past and present, archive footage, location photography and CGI to explore the terrifying consequences should the atmosphere's CO2 levels treble over the next 100 to 300 years, as predicted. Step by step, it paints a chilling picture of the world as the sea levels rise from between one and 70 metres, unravelling the science behind this cataclysm, revealing when it could strike and what its impact would be on humanity. The film also questions experts and politicians about what measures can be taken now to stop the current rise of CO2 emissions, and explores how extreme engineering will buy us time. But the message of this film is stark, spelling out in graphic detail the Earth's apocalyptic future that we have been avoiding.
