[Coral-List] sea level rise speeding up

I have used satellite (SST & SSH), tide-gauge data, and GPS products for 
many years.

Satellite data in particular is dependent on accurate calibration, and 
the quality of the processing algorithms (scientific guesswork?). When 
that earlier processing is shown to be wrong such as in this case it is 
not very reassuring.

More generally, I have experienced Hadley SST products with inexplicable 
discrepancies, GPS data which has shown land rising, falling and 
stationary depending on which 'solution' is employed, and even 
tide-gauge data held on central databases with unexplained errors.

Perhaps we are 'improving' in all this data collection and analysis. I 
hope so. In the meantime in trusting what is available it transpires 
that we are simply generating results that are rubbish. I guess it is 
time to start deleting some of the older (now inaccurate) papers - but
