Blockbuster sea level study may turn climate change orthodoxy on its head

Global sea levels have not continued to rise at the rates predicted by many scientists — and there is no evidence that climate change has contributed to any such acceleration, a new first-of-its-kind study has claimed.
The research found that the average sea level rise in 2020 was only around 1.5mm per year, or 6 inches per century, according to the paper’s authors, Dutch engineering consultant Hessel Voortman and independent researcher Rob de Vos.
“This is significantly lower than the 3 to 4 mm/year often reported by climate scientists in scientific literature and the media,” Voortman told independent journalist Michael Shellenberger.
Voortman was shocked that no researcher before had performed an analysis of real-world local data.
No evidence exists that climate change has caused an acceleration in global sea levels, a new study has claimed.
“It is crazy that it had not been done. I started doing this research in 2021 by doing the literature review. ‘Who has done the comparison of the projections with the observations?’ And there were none,” he told Shellenberger.
