Al Gore’s Oscar-winning environmental documentary exaggerated the likely effects of global warming on sea levels, a new study shows.
The film, An Inconvenient Truth, suggested that the sea would rise up to 20ft “in the near future” as the ice in Greenland or Western Antarctica melts.
Other documentaries have picture Britain deluged with water, showing the House of Commons submerged.
However, while some mainstream predictions project sea levels 2 to 4 meters higher by 2100, a new study published today in Science concludes that a rise in sea level between 0.8 and 2 meters is much more likely.
However, a rise of just a metre or more would wipe out the Norfolk Broads and the Wash, boosting the risk of devastating storm surges. And the new estimate does exceed that of thee latest Intergovernmental Panel on Climate Change report projects between 18 to 60 centimetres (7.2 to 24 inches) of sea level rise by 2100.
