iheartheidicullen @ 162: Sorry if my tone was intemperate, but really the SH and NH sea ice trends have been analysed at length online by Tamino and others, over the last year or two, with the clear conclusion that the SH anomaly trend is small (the anomaly at the maximum last year was about 1.5 % of the mean annual maximum, if I remember correctly) and not statistically significant (at the 95 % level, I think), whereas the NH trend is large (tens of percent), long - lived, and statistically very significant indeed.

I am a little puzzled at the trend, but that just means the sea level rise data as commonly presented doesn't paint a complete or accurate picture.

Putting it into the human - caused «climate change» context, this global mean of long - term sea level trend has clearly not been a function of the rapidly rising CO2 levels (see chart's plot of moving 360 - month average of atmospheric CO2 levels).

Different approaches have been used to compute the mean rate of 20th century global mean sea level (GMSL) rise from the available tide gauge data: computing average rates from only very long, nearly continuous records; using more numerous but shorter records and filters to separate nonlinear trends from decadal - scale quasi-periodic variability; neural network methods; computing regional sea level for specific basins then averaging; or projecting tide gauge records onto empirical orthogonal functions (EOFs) computed from modern altimetry or EOFs from ocean models.
