Breaking: no acceleration in sea level rise detected worldwide

[Eman623]

Takeaways:
1. Yes, sea level rise is occurring. No, it is not accelerating.
2. Sea level values simulated by the IPCC are systematically too high, on average about 2 mm/year higher than the measured values.
3. The actual average rate of rise is 1.7mm +/- 0.4mm per year
4. At the current rate of rise, by the year 2100, sea levels will be 5 inches higher than today.

And here I spent $200,000 putting my home on stilts.

A new peer-reviewed study published in the Journal of Marine Science and Engineering challenges a key claim of climate science: that global sea level rise is accelerating. An analysis of more than 200 long-term tide gauge records shows no evidence of such acceleration, while IPCC models systematically overestimate local sea level rise.

The paper also shows that IPCC models significantly overestimate local sea level rise in 2020. This new publication is a follow-up to an earlier paper from 2023 in which first author Hessel Voortman demonstrated that sea level rise along the Dutch coast was not accelerating.

These two paragraphs are the opening of a press release sent out on August 29 by engineer Hessel Voortman. Voortman spoke about his sea level research at the Clintel conference last year. Together with Rob de Vos (blogger at klimaatgek.nl), he has now published a scientific paper in which they demonstrate that sea levels are not rising at an accelerated rate worldwide. This is a spectacular result because climate scientists have been crying wolf about accelerating sea level rise in recent years.

Lol. Stilts are for flooding and storm surge, not for permanent sea in your yard.

sea level rise is increasing​

The global average sea level has been rising at an accelerated rate, with the rate of increase being more than twice that of the first decade of the satellite record. This trend is a direct consequence of climate change, driven by the melting of glaciers and ice sheets, and the thermal expansion of seawater due to rising global temperatures. The rise in sea levels poses a significant threat to coastal communities, ecosystems, and economies worldwide.

Well ... the quote from the abstract is "Statistical tests were run on all selected datasets, taking acceleration of sea level rise as a hypothesis. In both datasets, approximately 95% of the suitable locations show no statistically significant acceleration of the rate of sea level rise." [emphasis mine] ...

That's statistically different from "no acceleration" ... I wouldn't think 42 µm/yr/yr would haveany effect on how we engineer our buildings ... a single shaft of hair per year ...

For this we're supposed to panic? ...

The people who wrote the peer-reviewed OP article actually analyzed the collected data at the sea level stations, rather than looking at satellite imaging. Which would you say is the more definitive method?

I'm not the expert.

Which method do you want to be the most definitive?

You could ask Ding too!

Bangladesh is a good study subject.

Well, nobody sane thought that there ever was.

I'm not an expert, but I think looking at the actual sea level measurements to see if they are accelerating would provide the most definitive answer.

But then I am not as impressed by appeals to authority as some.

 

[JWBooth]

The Obamas would have you believe in rising sea levels, even as they buy seaside properties in Nanucket and Hawaii.

It hasn’t deviated much from the trend of the last 6,000 years.

Ask them how this compares to the sea level rise of 6,000, 10,000 and 15,000 years ago? You know… for a little context.

 

[Eman623]

Lol. Stilts are for flooding and storm surge, not for permanent sea in your yard.

There is no evidence floods and storms are more severe now.

 

[EMH]

There is actually no ocean rise at all, hasn't been any for the past 100 years.

What is your evidence of those sea level "rises?"

 

[Woodznutz]

We do have God's assurance that there will be no more global floods. That's something.

 

[ding]

What is your evidence of those sea level "rises?"

Google it, dummy.

Well now, how many multi-billion dollar seaports were flooded by those rapid sea level rises? Yes, let us put that in context. About a 300 ft sea level rise as we came out of the last ice age maximum. However, at that time we did not have the huge infrastructure in ports that we have today. Even a 1 meter sea level rise would cause trillions in infrastructure damage today. And we will get that before this century ends.
