UN warns global heating to hit at least 1.8C, overshooting Paris goal

UNEP report confirms 1.5C Paris target overshoot is now unavoidable, projecting at least 1.8C warming under the most optimistic scenario. The report underscores cascading risks to health, water, ecosystems, and coastal infrastructure, but does not specify new policy actions. This shifts the climate discourse from mitigation feasibility to adaptation necessity, with implications for climate policy and risk pricing.
