Global warming projected to pass 2°C around mid-century without faster emissions cuts

Nature reports that the UN’s latest climate assessment projects warming past 2°C around mid-century unless emissions cuts accelerate sharply. Initial estimates put global greenhouse-gas emissions roughly level with or slightly below 2024 in 2025, but researchers caution that one year cannot establish a lasting peak. Under current policies, warming is projected to reach 2.6°C–2.8°C this century. New Scientist reports the UN says the 1.5°C limit cannot be met without first overshooting it.
