There has been no sea level acceleration consistent with the alarmist global warming narrative.
A new statistical analysis[1] of global sea level rise patterns suggests that, as of 2020, approximately 95% of the 204 PSMSL tide gauges reliably contributing to estimates of global sea level rise show there has been no statistical acceleration in the modern rate of rise.
The 5% of gauges that do indicate acceleration cannot be attributed to “global warming” or climate change, but to local or geologic factors (i.e., vertical land motions).
So there has effectively been no acceleration consistent with the view that sea level rise is driven by a mechanism such as “global warming.”
“The statistical procedure detects accelerating sea level rise in a few isolated locations. This pattern is inconsistent with sea level acceleration driven by global phenomena.”
Furthermore, the global sea level rise rate today, in 2020, is only 1.5 mm/year. The IPCC models project sea levels should be rising at a rate of about 3.5 mm/year. Thus, the rate of rise projected by the IPCC is “biased upward with approximately 2 mm per year in comparison with the observed rate.”
