Between 2015 and 2025 is now confirmed as the hottest ever recorded in human history, marking an unprecedented surge in global temperatures.
This is according to the World Meteorological Organization (WMO) in its State of the Global Climate 2025 report released on Monday, March 23, 2026.
The report shows that the world’s oceans continue to warm at alarming levels, absorbing vast amounts of carbon dioxide — equivalent to about 18 times the annual human energy use each year over the past two decades.
The WMO report confirms that the past eleven years, from 2015 to 2025, are the hottest on record globally, with 2025 ranking as the second or third warmest year ever observed — about 1.43°C above pre-industrial levels.
Reacting to the findings, António Guterres, Secretary-General of the United Nations, warned that the planet is reaching a breaking point.
“The State of the Global Climate is in a state of emergency. Planet Earth is being pushed beyond its limits. Every key climate indicator is flashing red,” he said.
“Humanity has just endured the eleven hottest years on record. When history repeats itself eleven times, it is no longer a coincidence. It is a call to act.”
