This week, we're focusing Reflections on a single topic: coral reefs and whether solar geoengineering could help protect them. Coral reefs are entering a critical moment Last year saw the largest global coral bleaching event on record, with heat stress affecting reefs across nearly every ocean basin. The 2025 Global Tipping Points Report underscored a sobering reality: warm-water coral reefs have already crossed critical climate thresholds, with even modest additional warming risking widespread and lasting loss. Recent research is sharpening the picture of why reefs are so vulnerable. Scientists are finding that changes in ocean and atmospheric circulation can intensify heat stress and trigger bleaching – including during calm periods when heat builds up instead of dispersing. Separately, new findings published this week show that 2020 regulations requiring cleaner shipping fuels inadvertently increased heat stress on the Great Barrier Reef by removing sulfur pollution's cooling effect. These findings raise a question worth exploring: could measures like SRM, alongside rapid emissions cuts and other interventions, play a role in reducing risks to coral ecosystems? Next Thursday: A live discussion on SRM and coral reefs On January 29 (20:00 GMT / 15:00 ET), we're hosting a panel discussion exploring whether solar geoengineering could help protect coral reefs – and what limitations or new risks it might bring. ...
