Over the Last Two Years, the Sea Level Has Dropped by 3 Mm

Vinós is a neurobiologist.

Measured... where?

I'm not an expert in this arena, but I have read that it is expected for sea levels to rise in some areas and drop in others, but with an overall trend up.

Assuming one trusts climate.nasa.gov, and it would be weird if Vinós doesn't because that's where his graph comes from. But if one looks at https://climate.nasa.gov/vital-signs/sea-level/?intent=121 one can see a longer time series indicating 97.6mm of sea level rise since 1993. (Or at least those were the numbers when I looked a them in September 2025.)

This sort of Cherry-Picking is common among people with no training in statistics.

If his point was "hey, look, the last two years of data seems to contradict the previous 30, perhaps there's something going on here," then that is probably what he should have said that in his tweet.

There have been periods of "global warming hiatus" in the past where it appears global temperatures were falling, staying the same or not rising at the same rate as other times. Climate researcher, famed statistician and US senator Raphael Cruz (R-TX) argued a hiatus from 1993 to 2013 disproved the anthropomorphic global climate change hypothesis.

It's likely worth noting the weak statistical significance of small changes over small sections of a larger data set (because Vinós clearly doesn't.)

And it's a bit cold today, so what's this about global warming.
