IT seems the dire warnings about the oncoming devastation wrought by global warming were not dire enough, a top climate scientist says.Just think: We could save the planet a few years if Al Gore didn't have such a massive carbon footprint.
It has been just over a year since the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) published a landmark report warning of rising sea levels, expanding deserts, more intense storms and the extinction of up to 30 per cent of plant and animal species.
But recent climate studies suggest that report significantly underestimates the potential severity of global warming over the next 100 years, a senior member of the panel said.
"We now have data showing that from 2000 to 2007, greenhouse gas emissions increased far more rapidly than we expected," said Chris Field, who was a coordinating lead author of the report.
This is "primarily because developing countries like China and India saw a huge upsurge in electric power generation, almost all of it based on coal," Mr Field said ahead of a presentation to the American Association for the Advancement of Science.
Without decisive action to slow global warming, higher temperatures could ignite tropical forests and thaw the Arctic tundra, potentially releasing billions of tons of carbon dioxide that has been stored for thousands of years.
That could raise temperatures even more and create "a vicious cycle that could spiral out of control by the end of the century".
