Overview

• The World Meteorological Organization and UK Met Office forecast global mean temperatures between 1.2°C and 1.9°C above pre-industrial levels through 2029.
• Scientists calculate an 86% chance that at least one year between 2025 and 2029 will exceed 1.5°C and an 80% probability of surpassing 2024’s record warmth.
• There is a 1% possibility of crossing the 2°C threshold by 2029, which experts link to severe and potentially irreversible climate impacts.
• Arctic sea ice is expected to decline further in the Barents, Bering and Sea of Okhotsk regions, amplifying extreme weather risks worldwide.
• The report urges governments and businesses to accelerate emissions reductions and bolster adaptation strategies to limit escalating economic and ecological damages.
