Think it's hot now? The next five years will smash records, UN says
The United Nations predicts a 75% chance that global temperatures will exceed the 1.5°C threshold above pre-industrial levels between 2026 and 2030, with at least one year likely breaking the 2024 hottest-year record. The World Meteorological Organization warns of severe impacts, including Arctic warming, Amazon droughts, and extreme weather events like floods and wildfires, driven by continued fossil fuel use and a potential prolonged El Niño." "article": "The United Nations climate agency and the UK Meteorological Office project a 75% likelihood that global temperatures will surpass 1.5°C above pre-industrial levels between 2026 and 2030. This threshold, set by the 2015 Paris Agreement, marks a critical limit to avoid severe climate impacts, including ecosystem collapse and increased human risk. There is a 91% chance that at least one year within the next five will exceed 1.5°C, with an 86% chance of breaking the 2024 record for Earth’s hottest year. Temperatures are expected to range between 1.3°C and 1.9°C above late 1800s levels, accelerating warming to a quarter-degree increase per decade—a rate faster than previous trends. The Arctic is projected to warm nearly 3°F (1.66°C) by 2030, while the Amazon faces heightened drought and wildfire risks, threatening its role in mitigating climate change. Extreme weather—floods, droughts, and heatwaves—will intensify due to continued reliance on coal, oil, and gas, scientists warn. A strong El Niño event, expected to persist until 2028, will further drive temperature spikes, making 2027 a likely candidate for surpassing 2024’s record. Exceeding 1.5°C for an entire year could trigger unprecedented heat, food price shocks, and deadly wildfires, straining global infrastructure and agriculture. Experts emphasize that even small temperature increases worsen climate impacts, with no abrupt tipping point but escalating risks. The projections highlight the urgency of reducing greenhouse gas emissions to avoid irreversible damage to vulnerable ecosystems and human societies.
