Subject: Global sea level rise rate speeding up, 25 years of satellite data confirms

>>The rate of global sea level rise is accelerating as ice sheets in Antarctica and Greenland melt, an analysis of the first 25 years of satellite data confirms.
Key points

It was thought sea level rise was accelerating at steady 3mm a year Analysis of first 25 years of satellite data shows rate going up by 3mm a year, plus 0.08mm a year, every year. Acceleration largely being driven by melting of Antarctic and Greenland ice sheets and likely to increase in future, say scientists

The study, by US scientists, has calculated the rate of global mean sea level rise is not just going up at a steady rate of 3mm a year, but has been increasing by an additional 0.08mm a year, every year since 1993.

If the rate of change continues at this pace, global mean sea levels will rise 61 centimetres between now and 2100, they report today in the journal Proceedings of the National Academy of Sciences.

“That’s basically double the amount you would get if you only had 3 mm a year with no acceleration,” said the study’s lead author Steven Nerem of the University of Colorado.<<

So as the rate of increase is not constant, but is gradually increasing, 61 cm height sealevel rise by 2100, is likely to be even higher. It was not so long ago, some people even here, were saying that the expected sealevel rise of a few millimeters was nothing to be concerned about. Guess this proves them wrong.

Well I should hope so. So far, it’s been much less than global climate models have predicted.

Also it’s annoying that these predictions are often stated without any indication of what sort of prediction it is.

i.e. is it a scientific prediction (most likely based on available evidence, with percentile range of fairly unlikely lower and upper bounds)?

Or is it an engineering estimate (upper bound prediction, with a very small chance of being exceeded)?

Thanks, PF. Interesting.
