The report underscores the severe consequences of surpassing the 1.5°C and 2°C warming thresholds, including extended heatwaves, massive wildfires, and deadly floods, which have already caused significant disruptions globally in 2026. If current policies persist, warming could reach 2.6°C to 2.8°C by the end of the century, with a 10% chance of exceeding 3.4°C, which would have catastrophic implications. These risks highlight the urgent need for global action to mitigate climate change and adapt to its impacts.
