Coral reefs expand and thrive as sea levels rise, whereas they undergo millennia of growth hiatuses and “turn-off” or “mass mortality” phases when sea levels fall. According to a new global sea level reconstruction (Feldman et al., 2025), global sea levels were meters higher than today 7000 to 5000 years ago. Global sea levels fell […]

In a region of the world where tide gauges are not compromised by land subsidence or uplift, sea levels have not been observed to be rising since measurements began in 1894. According to a new study, when sea levels rise it usually has more to do with declining land movement (subsidence) or 20- to 60-year […]

Fifteen more new studies published in 2024 document meters-higher sea levels across the world during the Mid-Holocene, when CO2 hovered near 260 ppm. There were 45 studies published from 2022 to 2024 indicating sea levels were approximately 2 to 3 meters higher across the world about 7000 to 4000 years ago before declining to today’s […]

15 years ago, to illustrate its own demise due to the rising sea, the government of the Maldives once held a publicity stunt cabinet meeting underwater. Today, however, new airports are being built in the island state. Where’s the doom? Hat-tip: EIKE Similarly, is the story of the demise of the South Sea islands due […]

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 […]
