Climate Report Says 1.5°C Threshold May Be Breached in Four Years

A new scientific assessment published in Earth System Science Data finds that the global average temperature was 1.37 °C above pre‑industrial levels in 2025 and that, if greenhouse‑gas emissions continue at the current rate, the 1.5 °C warming limit could be exceeded in roughly four years. The report, compiled by more than 70 scientists from 56 institutions in 17 countries, highlights a record energy imbalance in the Earth system, accelerating ocean warming, a sea‑level rise of 23 cm above early‑20th‑century levels, and a three‑fold increase in marine heatwave days, with 65 such days recorded in 2025.

Global CO₂‑equivalent emissions reached a historic 56.8 Gt in 2024, leaving an estimated carbon budget of about 130 Gt before the 1.5 °C threshold is breached, a margin that could be exhausted by the mid‑2020s. Experts warn that the continuing rise in emissions intensifies extreme weather, permafrost melt, and coastal flooding. In Peru, environmental activist Jorge Zegarra Reátegui echoed the urgency, calling for accelerated emissions cuts and promoting circular‑economy projects through the Petramás initiative to mitigate climate impacts.

The findings underscore the narrowing window for meaningful climate action and the need for rapid transition away from fossil fuels worldwide.
