"A triple-whammy of hottest years ever recorded threatens irreversible damage, the UN has warned as the world's nations prepare to meet at the Cop30 climate summit in Brazil. This year is on course to be the second or third hottest ever, in records that stretch back 176 years, the UN World Meteorological Organization (WMO) said. It means 2023, 2024 and 2025 will be the three hottest on record, demonstrating that the world is now deep into the climate crisis."
"But the science is equally clear that it's still entirely possible and essential to bring temperatures back down to 1.5C by the end of the century, she said. That would require carbon dioxide to be sucked from the atmosphere, by growing new forests and using technology to remove and bury the CO2. Each year above 1.5C will hammer economies, deepen inequalities and inflict irreversible damage, said Guterres."
2023, 2024 and 2025 are on track to be the three hottest years in instrumental records stretching back 176 years, creating an unprecedented streak of high temperatures. The past 11 years will be the 11 warmest on record. Limiting global heating to 1.5C above preindustrial levels is now deemed virtually impossible without a temporary overshoot, driven by record greenhouse gas concentrations. Rapid carbon dioxide removal is required to return temperatures to 1.5C by century's end, through reforestation and engineered removal and storage. Each year above 1.5C will damage economies, deepen inequalities and risk triggering climate tipping points.
