Sea Levels Rising Twice as Fast as a Decade Ago, UN Warns of ‘Severe’ Ocean Crisis
The rate of global sea level rise has doubled over the past ten years, according to a new United Nations report, which warns that the world’s oceans are under “severe” and growing stress. Scientists say the accelerating rise threatens coastal communities everywhere, from small island nations to major cities, and urgent coordinated action is needed to prevent further damage [169387].
The findings come as climate scientists also warn that a powerful “super” El Niño event is strengthening, which could deepen the divide between rich and poor nations. El Niño, a natural warming of ocean surface temperatures in the Pacific, often triggers severe weather shifts worldwide. A “super” version is an extreme event, and experts say it will hit developing economies hardest because they lack the infrastructure to handle floods, droughts, or storms [169199]. Wealthier countries, with more resources to adapt, are better positioned to cope, meaning the disaster could worsen global economic inequality [169199].
If the El Niño arrives as predicted, it could be the strongest in a century, bringing severe drought to some regions, heavy flooding to others, and extreme heat waves worldwide [169112]. Experts are questioning whether communities can prepare for the worst impacts, as the event may test infrastructure and emergency response systems across multiple continents [169112].
Meanwhile, at the UN’s mid-year climate talks in Bonn, UN climate chief Simon Stiell urged governments to speed up their climate commitments. He warned that continued reliance on fossil fuels is causing economic instability and making countries more vulnerable to severe climate disasters, pushing nations to move from promises to concrete implementation [168616].
