Global warming projected to peak at 1.7–1.8°C by mid-century even in lowest-overshoot scenario

The UN Environment Programme's lowest-overshoot scenario projects a 1.7–1.8°C peak by mid-century, Reuters reports. It calls for an 18% emissions cut from 2025 levels by 2030, versus 5–8% under current national plans. Under current policies, the report projects 2.8°C by 2100. Its roughly 50% chance of returning to 1.5°C or below by then depends on large-scale carbon removal whose feasibility is uncertain.
