El Ni\u00f1o, declared by the National Oceanic and Atmospheric Administration (NOAA) just one month ago, is strengthening at a rapid clip. It has now reached \u201cmoderate\u201d strength weeks ahead of schedule and shows no sign of slowing down. According to the World Climate Service, sea surface temperatures in the Ni\u00f1o-3.4 region\u00a0of the Pacific Ocean have climbed 3.6 degrees Fahrenheit (2 degrees Celsius) above average, reaching the threshold for a \u201csuper\u201d El Ni\u00f1o. It remains to be seen whether this significant anomaly will hold, but on Thursday, NOAA forecasters said there is an 81% chance of a \u201cvery strong\u201d El Ni\u00f1o between October and December. That would make this event one of the largest\u2014potentially the largest\u2014since record keeping began in 1950. The Ni\u00f1o-3.4 region is the primary section of the equatorial Pacific that scientists monitor for El Ni\u00f1o and La Ni\u00f1a. Sea surface temperatures in this region have been record-high for a month straight, according to meteorologist Ben Noll. \u201cThe current streak is now just days away from the 40-day record set during the historic 1997 event,\u201d he said in an X post on Thursday.<\/p>\n
The compounding effects of climate change As this exceptionally strong El Ni\u00f1o unfolds, climate scientists are increasingly concerned that human-driven climate change will amplify its impacts. During El Ni\u00f1o, sea surface temperatures in the central and eastern tropical Pacific rise above average, pumping extra heat into the atmosphere and shifting the Pacific jet stream southward. This raises the global temperature and alters weather patterns in various ways across the world. Now that El Ni\u00f1os are unfolding against the backdrop of global warming, they can boost Earth\u2019s temperature into uncharted territory and exacerbate extreme weather events that are already growing more frequent and severe.<\/p>\n
\u201cThis is not a run-of-the-mill El Ni\u00f1o,\u201d Daniel Swain, a climate scientist at the University of California Agriculture and Natural Resources, told the Associated Press. \u201cWe might not expect to see the exact same impacts from this event as we have seen in historical ones.\u201d It\u2019s important to note that stronger El Ni\u00f1o events don\u2019t guarantee more severe impacts, but they can tilt the odds in favor of expected outcomes, according to NOAA. For the U.S., that means an increased likelihood of severe storms, heavy rainfall, and flooding in the South; a greater risk of tropical storms on the West Coast; and a heightened risk of heat waves and drought in the North.<\/p>\n
El Ni\u00f1o just getting started El Ni\u00f1o typically reaches peak strength between November and February, so this event still has months to ramp up. Some forecast models predict that sea surface temperatures in the Ni\u00f1o-3.4 region will peak at nearly 9 degrees F (5 degrees C) above average. For reference, the highest peak temperature anomaly ever recorded for El Ni\u00f1o was 4.5 degrees F (2.5 degrees C) during the 1982-1983 event, according to The Weather Channel. It\u2019s still too soon to tell exactly how strong this El Ni\u00f1o will be, but even the most conservative forecasts show peak temperatures well above the 1982-1983 record. Experts believe the combined impact of El Ni\u00f1o and climate change could make\u00a02026 the hottest year on record, but as temperatures continue to rise after El Ni\u00f1o peaks, 2027 will likely be even hotter. El Ni\u00f1o, declared by the National Oceanic and Atmospheric Administration (NOAA) just one month ago, is strengthening at a rapid clip. It has now reached \u201cmoderate\u201d strength weeks ahead of schedule and shows no sign of slowing down.
