AI Summary

Climate change is causing rapid declines in seaweed forests worldwide, outpacing restoration efforts and undermining seaweed restoration as a viable carbon‑dioxide removal strategy. An essay by Karen Filbee‑Dexter of the University of Western Australia and colleagues, published on September 8 in PLOS Biology, highlights these trends. The authors argue that the loss of kelp forests could erase up to 25 million hectares by 2050, threatening the ecosystems that depend on them. The study underscores the urgency of addressing climate impacts on marine habitats to preserve their carbon‑sequestration potential.
