After analyzing 385 studies related to coastal areas and sea level rise, scientists found a significant discrepancy between ...

Scientists studying coastal flood risk have been working with sea-level estimates that are systematically too low, according to a study published in Nature on March 4, 2026. Researchers Christian ...

Analysis shows average levels are 30cm higher than thought, and up to 150cm in south-east Asia and Indo-Pacific ...

A systematic review of nearly 400 coastal hazard studies has found that the vast majority relied on flawed assumptions about where sea level actually sits, leading to significant underestimates of ...

Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

A meta-analysis of sea-level rise studies shows a majority of assessments mistakenly used geoid models rather than land elevation data.

The Indian Ocean Geoid Low (IOGL), a significant gravitational anomaly, has puzzled scientists for decades. Research suggests it formed due to interactions between tectonic plates and mantle plumes ...

Most coastal risk assessments have underestimated current sea levels, meaning tens of millions of people face losing their homes to rising waters earlier than expected ...
