El Niño events can have significant global impacts, including altered weather patterns, increased rainfall in some regions, and droughts in others. For India, El Niño is often associated with weaker monsoon seasons, potentially affecting agriculture and water resources. Globally, it can lead to extreme weather events such as hurricanes, floods, and heatwaves. The warming of the Pacific Ocean also influences marine ecosystems, potentially disrupting fisheries and biodiversity. Early detection through NOAA's monitoring systems allows for better preparedness and mitigation of these risks.
