Scientists warn that Earth’s temperature is likely to rise again and again in the next five years, breaking the safe limit agreed by countries in 2015. The new climate models show a high chance—about three‑quarters—that the average temperature from 2026 to 2030 will exceed 1. 5 °C above pre‑industri
