Think it’s hot now? The next five years will smash records, UN says

The United Nations’ World Meteorological Organization (WMO) warns that global temperatures are overwhelmingly likely to repeatedly surpass the 1.5°C threshold above pre-industrial levels within the next five years. There is a 75% chance that the average temperature between 2026 and 2030 will exceed this critical limit, agreed upon in the 2015 Paris climate agreement, with a 91% chance that at least one year will break the 2024 record for Earth’s hottest year. The Arctic will warm nearly 3 degrees Fahrenheit (1.66°C) faster than the global average by 2030, worsening ice melt and amplifying extreme weather. The Amazon faces heightened drought and wildfire risks, threatening its role as a natural defense against climate change. Scientists emphasize that exceeding 1.5°C will intensify heatwaves, floods, and food price shocks, with irreversible damage to ecosystems like coral reefs and glaciers. The WMO forecasts a strong El Niño event, potentially lasting until 2028, which will further spike temperatures. If the next five years average above 1.5°C, Earth will warm 0.45°C in a decade—faster than previous rates. Climate models from 13 countries confirm this acceleration, with Arctic warming occurring 3.5 times faster due to reduced ice and snow reflecting solar radiation. Co-author Melissa Seabrook of the U.K. Meteorological Office notes that even small temperature increases worsen impacts, citing Europe’s record-breaking May heat. Imperial College London’s Friederike Otto warns that prolonged warming will strain infrastructure, agriculture, and human lives, leading to unprecedented extreme weather events. The projections highlight a potential acceleration in global warming, raising concerns about long-term climate stability.
