The 1.5°C Guardrail Is Dead: Record El Niño Confirms Permanent Climate Overshoot

A potentially record-breaking El Niño emerging in June 2026 will push global temperatures to 1.3°C–1.9°C above pre-industrial levels annually through 2030, confirming that the Paris Agreement's 1.5°C threshold is no longer a future boundary but a persistent operational baseline. This meteorological shift accelerates the collapse of natural carbon sinks, deep permafrost thaw, and systemic biodiversity loss, forcing a global pivot from prevention to adaptation.
