Data up until 1993, based on coastal measurements, show an annual rise of 1.7 millimeters.
Since then, however, satellite measurements have indicated a rise of three millimeters per year.
But does that mean that water levels are rising faster? Not necessarily.
“I find it unlikely that sea level started to accelerate just at the time we started to measure it with satellites,” says Simon Holgate, a sea level researcher with the National Oceanography Centre in Liverpool.
He says that the simple change in measuring technique could account for the change.
As a result, researchers don’t agree on what to expect. Whereas James Hansen expects a five meter rise, his colleague Simon Holgate says that “I think that even in the highest emission scenario we won’t exceed a global average of one meter of sea level rise by 2100.”

I expect James Hansen to be 6ft below ground level before we see a 6mm rise in sea level. And may God rest his wicked soul.
