The 1.5°C goal of the Paris Agreement is no longer viable

The 1.5°C warming limit established by the 2015 Paris Agreement is now unachievable, according to the UN Environment Programme's 2026 Emissions Gap Report, which states the opportunity to prevent exceeding this threshold has been lost. Exceeding 1.5°C above pre-industrial levels is now imminent and inevitable, shifting the focus to preventing warming from surpassing 2°C and eventually bringing temperatures back down to 1.5°C.
