'Super' El Niño is coming. What should you expect?
Summary
Climate scientist Julia Cole discusses a new study using Galapagos coral records to confirm that human-caused global warming is intensifying El Niño events. By analyzing geochemical data, her team found that the variability of warm events has increased by 36% compared to pre-industrial levels, marking a clear human fingerprint on the phenomenon. This research suggests that future El Niños will be more frequent and severe, leading to heightened risks of extreme weather, record-breaking temperatures, and accelerated ecological damage like coral bleaching.
