Just for the record, 12 mm is 1.2 cm. 2.54 cm 1 inch. patphil Mar 2024 #1

Yes... Think. Again. Mar 2024 #2

I think there is an annual cycle on top of the seasonal one IbogaProject Mar 2024 #3

So that rise was a little less than 1/2 inch in 6 months, or close to 1 inch per year.
If that rate of rise continued, it would be close to 1 foot in 12 years, or about 2 feet by 2050.
This is about double the current scientific projection on global warming.
Hopefully we don't see a continuation of this rate.

Think. Again.

....it seems every new report on any of the effects of climate chaos are always saying "faster than expected".

I think sea levels might get higher in the northern summer and lower in our winter as more of the southern ice is on Antarctica, where lots of our ice is on the Arctic ocean. But it is worrying if the rate of sea level continues to increase. 5 or 10 feet of sea level rise will be massively chaotic to world civilization.
