La Nina, the natural cooling flip side of the better-known and warmer El Nino climate phenomenon, has dwindled away after just three weak months. Federal weather officials made the announcement Thursday. Earth is now in a neutral setting in the El Nino Southern Oscillation cycle. That’s generally the most benign of the three states that help influence hurricane formation, droughts, floods and global temperatures. NOAA forecasts the neutral setting to last most if not all of 2025.
