More evidence emerges suggesting modern relative sea level (RSL) is among the lowest in several millennia. About 7000 years ago coasts were rapidly submerged beneath the sea at rates of up to 22 meters per year. Ancient shoreline elevation evidence indicates RSL along the coasts of Central Japan has fallen ~0.82 m since the 1800s […]

A stable current global sea level record has apparently been “corrected” to show accelerated rise since the 1990s. A few months ago we highlighted a new study indicating satellite observations reveal Antarctic-wide ice shelves gained +661 Gt of mass from 2009 to 2019. Instead of reporting on these actual observations, agenda-driven scientists have long been […]

The belief that modern sea levels are unprecedentedly high takes another hit. In southern South America sea levels were ~6 meters higher than today from 8000-6000 years ago, when CO2 hovered around 265 ppm but it was much warmer with less ice. Sea levels then gradually fell to present levels, the lowest in 8000 years. […]

The belief that modern sea levels and sea level change rates are unprecedentedly high takes another hit. Per a new study, sea levels were ~9.5 m higher than today about 8000 years ago (White Sea, northwestern Russia), then fell to ~7 m higher than today by around 4000 years ago. From that point in the […]

Both the history of the Holocene as well as trends from recent decades continue to undermine claims of unprecedented sea level or coastal changes operating in tandem with rising CO2 concentrations. Per a new published study (Martins et al., 2023), during the Mid-Holocene (~7000 to ~4000 years ago), when CO2 was a “safe” ~265 ppm, […]

Contrary to alarmist claims, the seas have been retreating and the coasts have been expanding seaward along the coasts of southern India since the early 1800s. Korkai was a port city, capital, and the principal trade center for India’s Pandya Kingdom from the 6th to 9th centuries CE. While Korkai was situated on the sea […]

Two new studies indicate centennial-scale sea level rise rates ranged up to 29-45 mm/yr during the period between 14,500 and 8000 years ago, when CO2 levels were 250 to 265 ppm. Modern global sea level rise rates have been reported to be 1.56 mm/yr for 1900-2018, decreasing slightly to 1.3 to 1.5 mm/yr during 1958-2014 […]

Despite what we hear from the media and climate activists, hard scientific findings show that Pacific and Indian Ocean island nations are doing just fine…not at all sinking away. Sea level rise alarmists are hip deep in exaggeration. Image: Potsdam Institute for Climate Impact Research. IPCC high-end sea level predictions for 2100 are “highly erroneous”. […]

Most of the 1100 Pacific and Indian Ocean islands have been growing, not shrinking in size, in the last half century. Activists convinced humans are able to exert fundamental control over ocean dynamics claim the rates of sea level rise and modern climate change are so rapid and unprecedented that modern changes are dramatically affecting […]

More evidence emerges that modern rates of sea level rise are approximately 20-50 times slower than natural rising rates occurring during deglaciations. In tropical areas coral reef fossils form terraces, or flat surfaces bordered by ascending sloping surfaces. Terraces are formed at or near sea level, so their relative geological presence can be interpreted as […]

Scientists have combined remote sensing data with machine learning to determine the Venice coast “is stable, or mainly subjected to accretion in the period 2015-2019.” Venice has been sinking into the sea (subsidence) at a rate of ~24 cm per century since the 19th century. Fortunately, in recent decades the regional sea level rise has rapidly […]

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 […]
