We're headed for an El Niño that is — quite literally — off the charts.
WMO's Global Seasonal Climate Update shows that El Niño is forecast to exceed the scale of global monitoring charts. Its impacts will be felt well into 2027.

This El Niño comes on the top of an already heating planet. In cities already struggling with heat, its effects can reach inside homes, workplaces, schools and hospitals.
But cities can prepare. Read on 👉 bit.ly/3WgzGaP

Following the glacial lake outburst in Northern Bhutan, the National Centre for Hydrology and Meteorology of Bhutan has urged residents to remain avoid riverbanks and take precaution as they monitor the situation. Flood alerts in Assam and West Bengal in India are also in place.
Concentrations of carbon dioxide, methane and nitrous oxide in our atmosphere are higher than ever before.
The WMO Greenhouse Gas Bulletin reports on the amount of gas that accumulates in the atmosphere, not new annual emissions.

In 2025, global CO₂ concentration rose to a record 426.8 parts per million. That's 153% of pre-industrial levels.
Every additional ppm traps more heat and supercharges the ocean and the atmosphere.
