Another alarmist sea level rise/coastal flooding narrative collapses under the weight of observational evidence. In 1989, the year the U.N. assembled what was to become the Intergovernmental Panel on Climate Change (IPCC), a “senior U.N. environmental official” warned that world leaders, or politicians, needed to enact policies to “solve the greenhouse effect” by the year […]

The paper appearing in Nature “An assessment of whether long-term global changes in waves and storm surges have impacted global coastlines” emerges with good news: The coasts of the world’s oceans are stable. Al Gore doesn’t have to worry about his beachfront home. Germany’s European Institute for Climate and Energy (EIKE) here presents its newest […]

Three new studies use evidence from elevated beach ridges to assess sea levels were 3-5 m higher than today near Thailand, 1-1.5 m higher near Australia, 2-5 m higher along the North Sea just a few millennia ago. The higher sea levels in the tropical regions (Australia, Gulf of Thailand) were “primarily driven by eustatic […]

Relative sea levels are lower today than at any time in the last 7000 years. According to 80-year-old aerial photograph evidence, scientists (Nakanishi et al., 2024) report the coastline of their studied area (Hokkaido, Japan) has “receded by approximately 100 m seaward” since 1944. This is a continuation of the long-term, millennial-scale decline in relative […]

The modern rate of sea level rise is not even close veering outside the range of natural variability. A new study reminds us that, 8200 years ago, near-global sea levels rose 6.5 meters in a span of just 140 years. This is 470 centimeters per century, 4.7 centimeters per year, during a period when CO2 […]

A new study reports Estonia’s climate was 2-3°C warmer and sea levels were 10-20 m higher ~7,300 years ago. Comparing detailed maps from 1915 and 1904 to 2004 and 2021 aerial images reveals the sea waters have receded from the coasts of Estonia so acutely that lagoons are fast disappearing, islands are being transformed into […]

Human footprints embedded into rock that used to be a sand beach at the limit of the seashore’s “swash flow” and high tide lie 20 to 30 meters above the present sea level. The footprints are dated to ~90,000 years ago. It is estimated that sea levels were globally about 6 to 9 meters higher […]

The sea level rise experienced in recent decades was supposed to lead to shrinking shorelines and inundated coasts. Instead, satellite observations reveal the globe’s island coasts expanded seaward (net) by 402 km² since 2000. In a new study, over 13,000 islands were assessed for coastal change over the last three decades (1990-2020). Only 12% of […]

Modern relative sea levels are near the lowest in the last 7,000 years. Two studies, independently published, identify Mid-Holocene sea levels in northern Norway (north of the Arctic circle) as 7 to 9 meters higher than today before declining to the present (Balascio et al., 2024, Nielsen et al., 2024). This region of the Arctic […]

Relative sea level change over the Holocene documents a much warmer past than today. Because it was so much warmer during the Early to Middle Holocene (~8000 to ~4000 years ago), there was significantly less water locked up on land (Greenland, Antarctica) in the form of ice sheets and glaciers. Instead, this water occupied ocean […]

Scientists have found evidence that the coastal land area grew (prograded) by 120 meters from 1900 to 1985 at a study site in central Denmark. Per a new study, relative sea levels (RSL) in central Denmark were “~4.5 m higher than present between c. 6.6 and 5.9 ka ago.” After this highstand, RSL declined towards […]

Comprehensive data analysis shows relative sea levels were anywhere from 1 to 7 meters (~3.9 m) higher than present throughout the Mid-Holocene at 15 of 16 assessed sites across Southeast Asia. A new study (Li et al., 2023) compiles highstand records from sites spanning Thailand, Vietnam, Singapore, Malaysia, Borneo, Sunda Shelf, Makassar Strait…and indicates that […]
