In reply to blurty:
> Sea levels have been rising at about 30cm a century since records began, the rate seemingly unaffected by recent increases in the rate of rise of temperatures, so far anyway.
Sea levels have been rising as follows:
20,000 to 10,000 years before present: 2 to 5 centimetres per annum (that is just under an inch to two inches).
10,000 to 6,000 years before present: 2 centimetres per annum (just under an inch).
6,000 years to the present, insignificant sea level rise (statistically insignificant).
