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.
