Record ocean surface temperatures and deadly US–Europe heat waves keep 2026 tracking among the hottest years on record, favoring YES.
Climate scientists are warning that 2026 could rank among the warmest years ever measured, a backdrop that frames the question of whether it will finish as the second-hottest year on record. As extreme heat smothered the eastern United States over the July Fourth weekend and Europe endured its own deadly heat wave, experts pointed to a strengthening El Niño as a key driver. "We know that temperatures are warming in the long term, linked to human-caused climate change, and El Niño acts to boost those temperatures temporarily," said Zachary Labe, a climate scientist at the nonprofit Climate Central. Whether 2026 lands in the top spot or settles into second place depends heavily on how the developing pattern evolves through the remainder of the year. [Los Angeles Times, Jul 06]
Ocean data reinforces the trend. The EU-sponsored Copernicus Marine Service reported a new record global sea surface temperature, making 2026 the third year in the last four to pass that threshold. With El Niño conditions arriving in the Pacific and high-heat events observed across other ocean basins, the average was expected to climb, and more daily records are forecast in the weeks ahead. Because oceans store and release vast amounts of heat, elevated sea surface temperatures are a leading indicator for annual global averages, sharpening the debate over whether 2026 finishes as the second-hottest year on record or higher.

Forecasters now expect the El Niño to intensify further. The latest outlooks from NOAA's Climate Prediction Center and the World Meteorological Organization indicate the pattern is already established in the tropical Pacific and could become one of the most intense on record, reshaping conditions across the United States through late 2026 and into 2027. A stronger El Niño typically adds temporary warming on top of the long-term climate trend, which could push 2026 toward or past prior benchmarks. The final ranking will hinge on second-half temperatures and how the event peaks. [Newsweek, Jul 07]
