2015 to 2025 was warmest decade on record, U.N. report finds

A United Nations report released on World Meteorological Day warns that the decade from 2015 to 2025 was the warmest on record, underscoring accelerating climate change trends. The findings align with years of scientific data showing rising global temperatures, with each successive decade consistently warmer than the last. The report's timing—on a day dedicated to meteorological awareness—amplifies its message to policymakers and the public ahead of continued climate negotiations. Rising temperatures directly threaten food and water security, increase extreme weather events, and raise sea levels, affecting billions of people globally. The warning comes as nations continue to grapple with how to meet climate commitments made under international agreements like the Paris Agreement.
