UN Report Names US Outlier in Global Warming Projections

The United Nations Environment Programme released its annual Emissions Gap Report on Wednesday, projecting that global temperatures will likely rise 1.7 to 1.8 degrees Celsius above pre-industrial levels by mid-century. Current policies suggest a warming of 2.8 degrees Celsius by 2100, while fully meeting existing pledges would still result in 2.6 degrees of warming. To reach the best-case outcome, greenhouse gas emissions must fall 18% from 2025 levels by 2030, though current national plans only project a 5% to 8% reduction.

The report identifies the United States as a major outlier among G20 nations. The withdrawal from the Paris Agreement and the rollback of climate policies under President Donald Trump have contributed to approximately half of a 0.3-degree Celsius increase in end-of-century warming projections. The administration has eliminated greenhouse gas limits for power plants and withdrawn support for wind and solar energy, while rising electricity demand from AI data centers and a cold winter further impacted emissions.

UN Secretary-General Antonio Guterres stated that while the 1.5-degree Celsius target may be overshot, governments must act to minimize the scale of that overshoot. White House spokeswoman Taylor Rogers dismissed the findings as part of a "woke Green Energy Scam." Additionally, the Intergovernmental Panel on Climate Change has failed to set a timetable for its latest report, which may hinder the 2028 global stocktake.
