The UN Environment Programme (UNEP) warned that the world is on course to overshoot the 1.5°C climate threshold within the next few years, with even the most optimistic scenario projecting warming to peak at 1.8°C. [^1]

The UN Environment Programme (UNEP) published a report titled 'Limiting Overshoot' in 2025 that identifies an 'overshoot, peak and decline' pathway as the best remaining option to minimize the magnitude and duration of global temperature overshoot above 1.5°C. [^2]

The UNEP report states that global temperature rise is set to exceed 1.5°C within the next few years, likely pushing climate impacts to increasingly dangerous levels. [^3]

A new report titled Limiting Overshoot released by UNEP states that crossing 1.5°C would expose countries and communities to escalating climate risks, including more extreme weather, ecosystem losses, threats to food and water security, and potentially irreversible changes to major climate systems. [^4]

The report says the most viable remaining pathway is to allow warming to peak and then drive temperatures back down through deep emissions cuts and carefully governed carbon dioxide removal. [^5]

UN Secretary-General António Guterres said recent extreme weather events were a warning of the consequences of continued warming, calling for an 'overshoot of ambition' to ensure any period above 1.5°C is as small and short as possible. [^6]

The most optimistic scenario in the UNEP report would see global temperature rise peak at 1.8°C above preindustrial levels, exceeding the Paris Agreement's 1.5°C goal. [^7]
