MELTING ice sheets in Greenland and Antarctica will cause the sea level to
rise much faster than previously anticipated, according to alarming new NASA
The alarming prediction was made by a research team led by James Hansen, from
NASA's Goddard Institute, and published in a peer-reviewed paper titled Climate
Change and Trace Gases.
The document argues the Earth is perilously close to entering a new era of
runaway climate change, warning that while conditions are currently classified
as "serious", they are likely to tip into "dangerous" over the next decade.
It says while the Intergovernmental Panel on Climate Change had forecast a sea
level rise of 18cm-59cm, that figure did not take into account melting ice
sheets in Greenland and Antarctica.
"That's beginning to lose mass and is situated on a bedrock below sea level, so
it's potentially unstable and could give a very large sea-level rise," Mr Hansen
Beyond Zero Emissions spokesman Matthew Wright said immediate action was needed.
"There is little point setting 2020 or 2050 greenhouse gas reduction targets,"
"We have too much carbon in the air now, in 2007."
