Re Ocean levels are rising; how much each years since ipss report of 2001?

Question

As the climate warms, ice melt faster, warmer water expand and together with more melt water and thermal expansion the oceans rise faster. Where are recent details outlining the rise in sea levels?

Answer 1

The 2007 IPCC report says it was (annually)1.8mm +/- 0.5 from 1961 - 2003, and 3.1mm +/- 0.7 from 1993-2003.

http://www.ipcc.ch/SPM2feb07.pdf

So a good number currently would be 4mm/year, and increasing.

Here's a page from NOAA that puts that in perspective, and offers a projection:

"The rate of sea level rise during the twentieth century has been nearly 2 mm per year, which is an order of magnitude higher than the average over the last several millennia."

The data has a lot of short term variability due to seasonality, short trem weather, etc. You really need to look at the long term average:

Answer 2

Sea level rise estimates from satellite altimetry are 3.1 +/- 0.4 mm/yr for 1993-2003 (Leuliette et al. (2004)). This exceeds those from tide gauges. It is unclear whether this represents an increase over the last decades; variability; true differences between satellites and tide gauges; or problems with satellite calibration.
