A new study by Dutch engineer Hessel Voortman and researcher Rob de Vos challenges the idea that complex climate-change models predicted massive and catastrophic sea level rises.
“The models, which extrapolated from observations in the Antarctic only, plus a host of assumptions about how the oceans respond to rising global temperatures, suggested sea levels increasing by 1 foot to 3 feet by 2100.”
However, as the researchers point out, this extrapolation of data was based on faulty assumptions and untested predictions:
“The Dutch researchers’ ‘first-ever global study of sea level rise’ refutes those claims — and raises the huge question of why no one else had bothered to test the predictions. As of 2020, they found, the worldwide rise is only around 1.5 millimeters per year — far less than the 3 mm to 4 mm (0.12 to 0.16 inches) a year routinely reported in scientific literature and the general news media.”
In an interview reported by the New York Post, researchers emphasize that earlier predictive models failed to verify against observed reality:
“For his own uses as a hydraulic engineer working with flood-protection and coastal-infrastructure adaptation projects, Voortman two years ago checked actual data for the Netherlands, and found it didn’t match the global predictions.
He was shocked to find that no one else was checking the models’ claims against observed reality, and set out at his own expense to do the global study.
Experts note that these flawed studies have served as the pretext for policy agendas focused on shifting away from hydrocarbons and increasing reliance on alternative resources like wind and solar power, and the New York Post argues these findings “may turn climate change orthodoxy on its head.”
