Study forecasts 9m sea-level rise next few hundreds years if temperatures meet 2C threshold rise.

Global sea levels could rise by up to 9m in the next few hundred years, even if the world manages to stabilise average temperatures to 2C above pre-industrial levels, according to a new study.

sea levels around the world during the last interglacial were between 6.6m and 9m higher than today. “During this period when temperatures were 2-3C above pre-industrial levels

New Orleans would be lost to the sea, much of southern Florida and Bangladesh and most of the Netherlands.

rise is higher than anything predicted so far because the new study takes into account the potential that the Greenland and west Antarctic ice sheets start to melt as the Earth warms.
This did not factor into the most recent assessment of the state of climate science by the Intergovernmental Panel on Climate Change (IPCC) in 2007

you look at things like coral reef terraces and how high they grew and
you look at old beaches that are now stranded
look at sediments that have textures that indicate they were deposited inter-tidally

“The warming we’re on track to do now is more than enough to commit us to last-interglacial levels of sea-level rise.”
