Think it’s hot now? The next 5 years will smash records, UN says

The World Meteorological Organization (WMO) warns Earth will likely surpass the 1.5°C warming threshold—set by the 2015 Paris Agreement—within the next five years. There’s a 75% chance global temperatures between 2026 and 2030 will average over 1.5°C above pre-industrial levels, with a 91% chance at least one year will break the 2024 heat record. The Arctic is projected to warm nearly 3°C (5.4°F) faster than the global average by 2030, accelerating ice loss and extreme weather. The projections, based on 200 simulations using 13 climate models, also predict a strong El Niño lasting until 2028, likely pushing 2027 into record-breaking heat. Even temporary breaches of the 1.5°C threshold carry severe consequences, including ecosystem collapse, food shortages, and deadly heatwaves. Scientists emphasize incremental warming compounds risks, with each tenth of a degree worsening impacts. Droughts and wildfires threaten the Amazon, a critical carbon sink, while rising temperatures strain coral reefs and glaciers. The WMO notes no sudden ‘cliff edge’ exists, but accelerating warming—potentially 0.25°C per decade—could signal a faster-than-expected climate shift. This aligns with concerns over intensifying extreme weather, food instability, and infrastructure vulnerabilities. The report highlights regional disparities, with the Arctic warming three times faster due to reduced ice cover and feedback loops. If the 1.5°C threshold is breached annually, global warming could reach 2°C within decades, triggering irreversible changes. Experts stress urgent action to mitigate long-term risks, though near-term heat records are now inevitable.
