“It’s crazy to think that 2 degrees celsius is a safe limit,” Professor Hansen told RN Breakfast on ABC Radio on Tuesday, adding that this would lock in several metres of sea-level rise by the middle of the century, New satellite data over the past decade indicate that the ice sheets are disintegrating faster than had been modelled by climate scientists.
“The ice sheets are losing mass faster and faster, with a doubling time of about 10 years,” Professor Hansen said. “If that continues, we would get sea-level rises of several metres by 40-50 years.”
