Marine geoengineering is being explored as a potential tool to mitigate the effects of climate-related phenomena, such as El Niño. However, its impact on marine life and ecosystems is still being studied and debated, with some trials finding no evidence of harm, while others raise concerns about potential risks and knowledge gaps. The effectiveness and consequences of marine geoengineering efforts are not yet fully understood, with some studies suggesting potential benefits, such as shielding oceans from heat waves, while others highlight the uncertainty and potential threats.
