“[D]uring the last 6 ky, repeated, meter-scale, rapid (<300 y) rises alternated with meter-scale falls…interpreted as global.” – Higgs, 2026 A new study uses excavation evidence (wall ruins, coins, pottery) to suggest sea level rise (SLR) rates reached ~4 m in ~70 yrs (60 mm/year, or 20 times the modern rate of 3 mm/year) from […]

Across the globe, vermetid gastropods (shelled snails, or molluscs) are a “critical paleo-sea level indicator” for ancient coastline reconstructions (Angulo et al., 2026). Along the Brazilian coast, vermetid shell radiocarbon ages indicate the relative sea level (RSL) was “more than 2 m above present” between 6000 and 7000 years ago. (The charts shown in the […]

Today’s sea levels are the lowest of the last several thousand years. Carbon dating evidence from the elevation of abandoned penguin rookeries (and other proxies) reveal relative sea level (RSL) was ~30 m higher than today across East Antarctica about 8000 years ago (Small et al., 2025). Following that highstand RSL fell rapidly at rates of […]

Fundamental assumptions in projections of alarming, CO2-induced global warming in the coming decades are undermined by a new long-term energy budget analysis. In a new study scientists have acknowledged the modeled assumptions forecasting nature’s response to the presumed human-driven radiative forcing of ocean heat uptake, thermal expansion, and sea level rise rates do not align […]

Germany’s Klimanachrichten here publishes an article titled “The Disappearing Islands (That Don’t Want to Disappear)” summarizes findings suggesting that the widespread assumption about low-lying islands inevitably sinking due to rising sea levels is too simplistic and detached from reality. Earlier, the media often tried to scoff at and discredit findings from inconvenient sea level experts, […]

The mechanisms driving the meters-higher sea levels a few thousand years ago do not support claims that CO2 is a driver. A comprehensive analysis (Zhang et al., 2025) of the South China Sea region indicates warmer sea water was fundamentally responsible for sea levels that were, on average, 2-3 meters higher (and in some regions […]

There has been no sea level acceleration consistent with the alarmist global warming narrative. A new statistical analysis 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 […]

New research from Indonesia indicates that from about 10,000 to 6000 years ago, when the ocean was warmer than today, coral reef growth was rapid, averaging ~6 mm per year. Sea levels rose rapidly from the Early to Mid Holocene in this region, as they were up to 2 m higher than today 6000 years […]

The narrative that says relative sea level changes are driven by variations in atmospheric CO2 concentrations has taken another hit. Before relative sea level (RSL) declined to its present position over the last millennium, Africa’s Atlantic coast RSL ranged anywhere from 0.8 to 4 meters higher than today between 5000 and 1700 years ago (Vacchi […]

Another day, another new study has sea levels 2.5 to 3.2 m higher than present from 7000 to 6000 years ago. This one is from the Arabian Sea (Oman). Embedded mollusc carbonate deposits dated to the Mid-Holocene have been located far inland from today’s shoreline, documenting the meters-higher relative sea levels at that time. Sea […]

The evidence for a much warmer Mid-Holocene keeps accumulating. According to a recent paleoclimate study, today’s Gahai Lake (China) reconstructed surface sediment warm season temperature is 9.4°C. This is similar to the region’s documented meteorological station temperatures (8.8°C, May-September). The reconstruction’s average Gahai Lake sediment warm season temperatures dating to 8000 to 3500 years ago […]

Yet another new study affirms sea levels were meters higher than today on the Bohai Sea coast during the Mid-Holocene before declining to today’s levels over the last few millennia. The Earth was less glaciated at this time, or from 9000 to 4000 years ago, meaning there was less water locked up on land as […]
