New study says sea-level risk may be higher than previously estimated
A peer‑reviewed Nature study shows most prior sea‑level projections used coastal baselines that were too low, likely underestimating risk. By anchoring sea levels to measured coastlines, the study finds a 1‑meter rise could flood about 37% more land, affecting 77–132 million people, with the Global South most at risk, and calls for updated, standardized coastal‑hazard assessment methods.
