New Study Indicates North American Pacific Coast Sea Levels Declining From 1952-2014

Share this...

Sea level changes along the Pacific coast have not been cooperating with an alarmist narrative.

New research reveals sea level rise has decelerated from ~5 mm/yr from the 1970s to 1990s down to about 1.5 mm/yr since the late 1990s along the Peruvian coast.

Further, the entire North America Pacific coast has undergone “statistically significant negative trends” (-0.11 to -33 mm/yr) in sea level change over the 1952-2014 period.

Historically, this region of the world had sea surface temperatures about 4°C warmer than today throughout much of the last several thousand years (Salvatecci et al., 2019). Temperatures have been declining precipitously in recent decades (as indicated by the black star markings in the below study).

Boretti (2022) indicates the IPCC has been using “inappropriate” methods to claim rising greenhouse gas emissions will lead to 15 mm/yr sea level rise rates by 2100.

The actual rate of sea level rise from tide gauges is globally less than 1 mm/yr, and “the present acceleration is small.” Subsidence and uplift are up to 10 times more determinative of relative sea level variability than eustatic change.

    The goings on of the OR/WA/BC are complicated by the Cascadian Subduction Zone.
    The coast is being slowly lifted (sea level down) until the earthquake occurs, then expect the coast to drop about a meter. The last such big quake was in January of 1700.

    I’m 175 miles east of the coast. Those west of the Cascade Mtns. will see devesting impacts and many deaths.

    That proves that the heat from Man Made Global Warming is evaporating the oceans rapidly. We’re doomed.

    Total BS
    NOAA tide gauges all around the world show a fairly steady relative sea level rise since the late 1800s, with very few tide gauge exceptions, obviously from local height changes. Why this website wastes space on this claptrap is a mystery to me.

      Mr. Greene explain, NOAA has tide gauges all around the world but on web site only show in US of A.

      Why you waste comment with false information?
