Sentences with phrase «if global sea levels»

You need a lesson in street smart logic: if no individual tide gauge records show a recent surge (and only a tiny fraction of long running ones show any trend change at all in recent decades), then claims that sea levels are surging are simply not tenable, for if GLOBAL sea levels are rising you would by logic alone expect that this would show up in actual single sites all over the globe.

Note that this sampling noise in the tide gauge data most likely comes from the water sloshing around in the ocean under the influence of winds etc., which looks like sea - level change if you only have a very limited number of measurement points, although this process can not actually change the true global - mean sea level.
