Is sea level really an issue?
This is likely to be controversial and dismissed by some as invalid, which is their problem.
The RSS data is monthly.
Topex/Jason data is sampled roughly every 10 days, processed into monthly and then normalised to the RSS data.
Both month data were low pass filtered at 10 years, with end correction. This is likely to be dismissed as impossible, look, it is self evidently about right.
All four are plotted above.
Other work has suggested there is a correlation between temperature and sea level, sea level lagging perhaps 4 years. (I doubt many people think that sea level causes temperature)
The actual sea level rises being talked about are extremely small relative to the size of the planet.
What if the top few x metres of sea water are warmed by 0.2K?
