Researchers, including John Church of the Centre for Australian Weather and Climate Research, presented evidence that Greenland and Antarctica are losing ice fast, contributing to the annual sea-level rise. Recent data shows that waters have been rising by 3 millimetres a year since 1993.
Church says this is above any of the rates forecast by the IPCC models. By 2100, sea levels could be 1 metre or more above current levels, he says. And it looks increasingly unlikely that the rise will be much less than 50 centimetres.
