Sea level rise in Pacific and Indian oceans ‘Much slower than climate models predict’ – Rising thanks to that?
Via Kenneth Richard above 3. January 2022
More than 700 low-lying islands in the Pacific and Indian Oceans have coastlines that have stabilized and expanded since the 1980s. Relative sea level rise is only +0.46 mm/year in these regions. with an “almost small acceleration of +0.0091 mm/year²”.
The claim that sea levels are rising so quickly that low-lying islands are sinking into the seas all over the world is a wholesale myth.
In fact, the opposite has been observed via satellite. A 2019 global scale analysis of 709 islands in the Pacific and Indian Oceans found that 89% are stable or growing in size and that Are not islands larger than 10 hectares (and only 4 of the 334 islands larger than 5 hectares) have decreased in size since the 1980s (Duvat, 2019).

As Dr. Alberto Boretti asserts in a new paper, one of the main reasons that islands in the Pacific and Indian Oceans are not mercilessly submerged under the sea as a result of today’s “catastrophic” climate change is that sea level rise is only is growing “very slowly” in these areas: 0.46 mm/year in recent decades. Acceleration is “almost small” 0.0091 mm/year².
In short, “absolute sea levels are rising much more slowly than predicted by climate models.”
