Globe Sees 70% Above-Average Heat, With 8% Hitting Record Warmth

Q: With a 'Super El Niño' amplifying record heat, are we entering a new, more volatile climate reality?

Yes. The evidence points to a more volatile climate reality, with El Niño acting as an amplifier on top of long-term human-caused warming rather than the root cause. The immediate signal is unusually broad and intense heat. More than 70% of the planet has been warmer than average in early 2026, while only about 1% has been cooler. March and April 2026 were among the warmest on record globally, and the last 12 months averaged about 1.42°C above pre-industrial levels. The western United States, much of Asia and the Arctic have stood out, with some areas posting record heat. What makes this more serious is the background state of the climate system. Greenhouse gas concentrations are at record highs, Earth’s energy imbalance is the highest in the observational record, ocean heat content hit another record in 2025, and Arctic sea ice in March 2026 was the lowest on record. Those indicators show the planet is still accumulating heat. A strong El Niño now developing could push temperatures higher later in 2026 and into 2027. Scientists stress that climate change does not clearly make El Niño more frequent or stronger, but it does make its impacts harsher because the atmosphere and oceans are already warmer. That raises the odds of more severe heatwaves, marine heatwaves, heavy rainfall, flooding in some regions, and drought and wildfire risk in others. The broader trend is clear: this is not a temporary anomaly but a natural climate swing superimposed on a steadily warming world.

More than 70% of the planet has logged well above-average temperatures so far this year, with 8% experiencing record-breaking warmth.
The hottest anomalies span parts of the western United States, Asia and the Arctic, while only about 1% of Earth has seen well below-average temperatures.
That lopsided early-year pattern points to a notably warm global start and may foreshadow broader temperature extremes later in 2026.
