Meteorologists warn that global temperatures could climb to record levels in 2026

Meteorologists warn that global temperatures could climb to record levels this year as the likelihood of an El Niño event increases. Forecasts from the National Oceanic and Atmospheric Administration (NOAA) suggest there is a 50–60% chance that El Niño will develop between July and September, potentially adding further heat to an already warming planet.
Before that, climate models indicate a transition from La Niña to neutral conditions during the February–April period. However, scientists caution that forecasts made early in the year remain uncertain and conditions can still change.
El Niño and La Niña are opposing climate patterns linked to sea surface temperatures in the Pacific Ocean. Normally, trade winds push warm water westwards across the ocean. During El Niño events, these winds weaken or reverse, allowing warmer waters to spread eastwards and altering global weather patterns.
One of the most significant effects of El Niño is its tendency to increase global temperatures. Scientists estimate that a typical event can temporarily raise the planet’s average temperature by around 0.1 to 0.2°C. While this rise is smaller than the long-term warming caused by human-driven climate change, it can push global temperatures to new records when layered on top of existing warming trends.
El Niño is also associated with more intense heatwaves in tropical regions and changes in rainfall patterns around the world. Some areas experience drought, while others face heavier rainfall and flooding.
At the same time, scientists are updating how these events are measured. Because the planet has warmed significantly due to greenhouse gas emissions, what was once considered “normal” ocean temperature is shifting. NOAA has therefore introduced a new index comparing Pacific temperatures with those across the wider tropics.
Even with these uncertainties, experts say the possible return of El Niño could make the coming months among the hottest ever recorded globally.
