Sea Levels Are Already Higher Than Many Scientists Think, New Study Shows
Key Points:
- New research published in Nature reveals that many scientific studies have underestimated current coastal sea levels by 8 inches to a foot on average, leading to an underestimation of how many people live near rising oceans.
- The discrepancy is particularly large in regions with complex ocean dynamics, such as Southeast Asia and Pacific nations, where coastal sea levels may be several meters higher than previously estimated.
- While the rate of sea-level rise and overall damage projections remain valid, scientists have been using inaccurate baseline sea-level data, affecting predictions of future land and population vulnerability.
- This finding highlights significant challenges in current mapping methods despite advances in GPS and satellite technology, impacting government and policymaker efforts to plan for climate change adaptation.
