Ice Sheets Will Disappear Ahead of Schedule
(October 11, 2012) One of the world’s foremost climate scientists has warned that vulnerable island states may need to consider evacuating their populations within a decade due to a much faster than anticipated melting of the world’s ice sheets.
Michael Mann, director of the Earth System Science Center at Pennsylvania State University, said the latest evidence shows that models have underestimated the speed at which the Greenland and west Antarctic ice sheets will start to shrink.
Mann, who was part of the IPCC team awarded the Nobel peace prize in 2007, said it had been expected that island nations would have several decades to adapt to rising sea levels, but that evacuation may now be their only option.
His warning comes just weeks after the National Snow and Ice Data Centre in Boulder, Colorado disclosed that sea ice in the Arctic shrank a dramatic 18% this year on the previous record set in 2007 to a record low of 3.41m sq km.
“The models have typically predicted that will not happen for decades but the measurements that are coming in tell us it is already happening so once again we are decades ahead of schedule.
“Island nations that have considered the possibility of evacuation at some point, like Tuvalu, may have to be contending those sort of decisions within the matter of a decade or so.”
Mann says the Pacific islands, which are only 4.6 meters above sea level at their highest point, are facing the imminent prospect of flooding, with salt water intrusion destroying fresh water supplies and increased erosion.
Suggesting evacuations would accelerate a change in public consciousness around the issue of climate change, he said: “Thousands of years of culture is at risk of disappearing as the populations of vulnerable island states have no place to go.
