UN weather agency confirms hottest decade on record

GENEVA, March 23 (Reuters) - The years between 2015 and 2025 have been the hottest since records began, the U.N. weather agency said on Monday, with 2025 ranking either second or third overall.

• The World Meteorological Organization report said 2015-2025 were the hottest 11 years since records began in 1850.

• 2025 was either the second or third hottest on record, the WMO State of the Global Climate report said, at about 1.43 degrees Celsius above the pre-industrial average.

• This confirms an earlier report from the WMO that 2025 was one of the three hottest on record.

• Glacier mass loss at key sites was among the five worst on record, the report said, with exceptional declines reported in Iceland and North America.

• "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," said United Nations Secretary-General Antonio Guterres.

• The report also confirmed that 2024 was the hottest year at about 1.55 degrees C above the pre-industrial average.

• Governments pledged under the 2015 Paris Agreement to try to avoid exceeding 1.5 degrees C of global warming.
