Sea level could be up to a meter higher than estimated, opening the door to new coastal risks
A new scientific study warns that sea levels on the world's coasts could be considerably higher than previously estimated, implying that the impact of rising oceans due to climate change could arrive sooner and affect more people than expected...
TL;DR
- A new study indicates global sea levels may be significantly higher than previously estimated, potentially by 30 cm on average and up to a meter in some regions.
- This discrepancy arises because many previous studies relied heavily on theoretical models, neglecting crucial observational data like tides, winds, and currents.
- This methodological 'blind spot' could mean coastal flooding risks are underestimated, potentially affecting 132 million more people globally if sea levels are a meter higher.
- While future sea-level rise projections may not change, the current baseline is likely higher, necessitating a re-evaluation of global measurements and risks for coastal communities.
- Experts not involved in the study have deemed the findings 'relevant' and 'surprising,' suggesting that climate change impacts may have been 'systematically underestimated.'
