GENEVA – A comprehensive climate assessment released Monday by the United Nations meteorological organization has documented unprecedented global warming, revealing that the span from 2015 to 2025 constitutes the warmest period since temperature monitoring commenced in 1850.
According to the World Meteorological Organization’s latest State of the Global Climate assessment, 2025 secured its position as either the second or third warmest year ever recorded, with global temperatures measuring approximately 1.43 degrees Celsius higher than pre-industrial baselines.
The findings validate previous WMO analyses that identified 2025 among the three warmest years in documented history. The organization’s data also established 2024 as the single hottest year on record, with temperatures soaring 1.55 degrees Celsius beyond pre-industrial measurements.
Ice loss emerged as another alarming indicator, with glacier retreat at monitored locations ranking among the five most severe on record. The report highlighted particularly dramatic ice losses across Iceland and North America.
UN Secretary-General Antonio Guterres delivered stark warnings about the climate findings. “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,” Guterres stated.
These temperature increases carry significant implications for international climate commitments. Under the 2015 Paris Agreement, world governments established goals to prevent global warming from surpassing 1.5 degrees Celsius above pre-industrial temperatures.
