Das heißt, wir können damit rechnen, dass der Meeresspiegel in den nächsten zehn Jahren um 5 cm (fast 2 Zoll) ansteigen wird. Häufigere Überschwemmungen, verstärkte Küstenerosion, Eindringen von Salzwasser, größere Schäden durch Sturmfluten …
Die gute Nachricht? Der Übergang zu erneuerbaren Energien ist in vollem Gange, und die ständig steigenden Kosten, die der Gesellschaft durch Schäden durch fossile Brennstoffe entstehen, werden dazu beitragen, diesen Übergang zu beschleunigen.
„Erheblicher“ Stress für die Ozeane, da sich die Rate des Meeresspiegelanstiegs in 10 Jahren verdoppelt, warnt die UN
The rate of sea level rise has doubled in 10 years. In 2023 alone, global sea level rise was 4.3 mm.

Well under way, except in the US where Trump is scrapping renewables for coal and more oil, seemingly just out of spite.
Why does everyone forget that the polar icecaps melted 10,000 years ago and we had massive sea level rises – example UK and Ireland no longer connected to Europe and Tasmania no longer connected to Australia and the same right around the world.
Does it mean that?
It rose by x, therefore it will rise by z?
Sea levels rise and drop year on year; it’s not consistent like you say.
This is a false premise.
Not to say there isn’t a concern, but this isn’t the concern.
Nitpick on the 5 cm figure: that assumes the rate stays frozen at 4.3 mm/yr for the next decade. But the headline finding is that the rate doubled in ten years, so it’s even more than that. If the last decade’s trend simply repeats, the rate will be ~8.6 mm/year by 2036, and the decade’s total comes out to 6.5+ cm, not 5.
The report has an interesting stat about the accerlation: 16% of ALL ocean heat gain since 1955 happened after 2018. The ocean has absorbed ~90% of excess heat from emissions, thermal expansion alone drives a good chunk of the sea level rise, even before adding ice sheets to the calculation. So 5 cm is the floor forecast of what could happen.
Does the water table move higher with sea level rise?
