Global Warming Limit of 1.5 Degrees is Now Out of Reach, Warns UN Report

The 1.5 degree Celsius temperature goal is now completely out of reach, and the world can only hope to limit global warming to 1.8 degrees before trying to lower it later. A new UN report states that years of weak climate action make the breach of the 1.5 degree target from the 2015 Paris Agreement totally unavoidable.

Country Emissions

The Emissions Gap Report released on Wednesday shows that the United States saw its yearly emissions rise by over 133 million tonnes of CO2 equivalent in 2025, which is the highest for any nation. Emissions also grew in China, while at least one dataset indicates a small slowdown in India, the world's third largest emitter. Across the globe, total greenhouse gas emissions in 2025 stayed flat at about 58.4 billion tonnes of CO2 equivalent, roughly matching 2024 levels.

Context

These findings mark a major shift from past climate assessments that suggested a small window to meet the Paris Agreement goals still existed if governments acted fast. Global temperatures continue to rise when countries fail to cut greenhouse gases like carbon dioxide and methane fast enough.
