📝 英文原文：
A Super El Niño is brewing and it could bethe most intense in decades, threatening a dramatic increase in deadly extreme weather. But what if there was a way humans could dial down the ferocious impacts of the most severe El Niños by temporarily dimming the sun?That’s the question a group of scientists has investigated in a new study published Wednesday in the journal Science Advances.🌊🌩️Get your forecast in the CNN Weather AppEl Niño is a natural climate pattern originating in the tropical Pacific Ocean, which typically boosts global temperatures and fuels extreme weather. It’s being compounded by human-driven climate change, which is ramping up the planet’s background temperature, pushing El Niño years into increasingly extreme territory — with devastating impacts on human lives and global economies.The study, led by scientists at Scripps Institution of Oceanography,focused on whether ahighly controversial techniquecalled solar geoengineering could be used as a tool to tamp down the severe heat, fires and other impacts El Niño brings.Specifically, they looked at “marine cloud brightening,” which involves spraying particles into ocean clouds in order to reflect sunlight away from the Earth and back into space.Children walk on a sandbank in Novo Airao, Amazonas state, northern Brazil, on October 1, 2024. An El Niño-fueled drought pushed several tributaries of the Amazon River to critical lows in 2024.Michael Dantas/AFP/Getty ImagesThe researchers couldn’t conduct real-world geoengineering experiments to test the idea for fear of “disastrous unintended consequences,” so instead they turned to a “natural experiment,” they wrote in a statement accompanying the report.Australia’s “Black Summer” bushfires in 2019 and 2020 incinerated tens of millions of acres and contributed to the deaths of hundreds of people. They also produced plumes of smoke filled with sun-reflecting particles, which mixed with clouds over the Pacific Ocean.Previousresearchhas found these ultra-refl
