Dates
Assessment published 23 September 2026 · Forecast period June 2026–February 2027
Evidence
A forecast, not a death toll

A University of Chicago Climate Impact Lab model projects approximately 451,000 excess heat-related deaths globally over June 2026–February 2027 against an average year. The larger figure covers the full nine-month period; its estimate for September–February alone is 239,000 ±11,000. The model projects 66,800 additional deaths in the Sahel over the full period.

Protected areas are expanding; effective protection lags

Dates
Research published 23 September 2026
Evidence
Preliminary progress assessment

Research reported on 23 September estimates that about 20% of terrestrial and inland-water areas and 10% of marine areas are formally protected against a 30% target for each by 2030. Only 3.5% of the ocean is assessed as effectively protected. These are NGO-led findings; the final official UN progress review is due next month.
