UN SCIENTISTS have warned the world’s climate is more out of balance than ever recorded, with every key climate indicator flashing red today, sparking fresh pleas for politicians to back renewables.

The World Meteorological Organisation’s (WMO) annual “state of the global climate” report said millions of people were affected by intense heatwaves, heavy rainfall, wildfires, drought, tropical cyclones, storms and flooding in 2025.

UN secretary-general Antonio Guterres said the global climate is in a “state of emergency” as the planet “is being pushed beyond its limits.”

The WMO confirmed 2015 to 2025 as the hottest 11 years on record.

The global average temperature last year was the second or third hottest year on record, depending on the dataset — about 1.43°C above the 1850-1990 pre-industrial average.

While 2024 was found to be the warmest year on record, this was partly driven by the warming El Nino weather phenomenon.

But the world is now experiencing cooler El Nina conditions. Forecasters recently warned that another El Nino peak could be seen towards the end of this year.

WMO scientist John Kennedy said: “If we transition to El Nino, we will see an increase in global temperature again, and potentially to record levels (in 2027).”

The figures show the world continued to get closer to long-term average temperatures breaching the key warming threshold of 1.5°C — beyond which, increasingly severe compounding climate impacts are triggered.

Green New Deal Rising co-director Hannah Martin said: “The question is whether the likes of Nigel Farage and his billionaire backers will take any notice as they continue to advocate for the UK to remain in thrall to the rollercoaster of international fossil fuel markets and profiteering energy company and abandon the clean, green energy transition which would provide cheap, reliable, home-grown energy.”

Friends of the Earth’s head of policy Mike Childs said: “Our dependence on fossil fuels is driving instability, conflict, soaring energy bills and the climate crisis itself.

“The solutions are clear: better energy efficiency and unleashing the world’s abundant renewable power. What’s missing isn’t technology — it’s the political will to act.”

Greenpeace UK head of climate Mel Evans added: “This is another reminder that there can be no stability or security in a world built on fossil fuels.”
