Scientists are exploring a potential climate solution, involving seeding clouds with seawater, that may be able to prevent or mitigate the effects of El Niño. El Niño is expected to occur, with some reports indicating it has already started, and is anticipated to bring extreme weather conditions such as heat, floods, and droughts. The severity and potential impacts of El Niño are still being assessed, with various regions around the world being warned to prepare for possible strong effects.
