> A new first-of-its-kind study by Dutch researchers

reading through [0] the affiliations of the "researchers" is the first red flag I notice.

the lead author is Hessel Voortman, from the Hessel Voortman Engineering Consultancy. his co-author is Rob De Vos, an "independent researcher".

by itself, that isn't necessarily a problem...but I'd prefer to read papers about climate change from actual experts in climate change, not Guy Who Owns Engineering Company and His Buddy

the next problem, from the abstract:

> We used two datasets with local sea level information all over the globe. In both datasets, we found approximately 15% of the available sets suitable to establish the rate of rise in 2020.

only 15% of the data being suitable seems kind of surprising. they elaborate on their criteria:

> The present study aims to estimate the long-term rates of sea level rise in 2020. To do so reliably, data were selected according to the following criteria:

> - Latest year in the dataset not earlier than 2015, this being a compromise between the desire to have data up to 2020 and the desire to have as many locations included as possible

> - Data available over a period of at least 60 years

> - At least 80% of the years in the range with data available

> Satellite data do not fulfill our second criterion and were, therefore, not used.

so they have a bunch of data, they come up with some cutoffs that discard 85% of the data, then draw conclusions from the other 15%?

in particular, satellite data hasn't been around for 60 years, so...toss it all out, I guess? couldn't satellite data from the past 30 years still be used to support their findings? couldn't every-other-year data fill the same purpose as well?

this smells a bit like p-hacking...if you can exclude data based on arbitrary criteria, you can reach any conclusion you want by excluding the right data.

but anyways, I think it's heartwarming that climate denial is still being done by humans. you'd think AI would have taken over that job by now.

Has not accelerated, but sea level is still rising steadily.
