A new international climate assessment, the Indicators of Global Climate Change (IGCC) report, warns that the world could breach the 1.5°C warming limit within four years. Human-induced warming reached 1.37°C above pre-industrial levels in 2025, and the remaining carbon budget for 1.5°C is only 130 billion tonnes of CO2, which could be exhausted in about three years at current emission rates. The report, published in Earth System Science Data, highlights record greenhouse gas emissions of 56.8 billion tonnes of CO2 equivalent in 2024 and a growing Earth energy imbalance. Scientists also note accelerating sea-level rise and more frequent marine heatwaves, stressing that current emissions cuts are far from sufficient to meet Paris Agreement goals.
