The World Meteorological Organization (WMO) said 2025 had continued a three-year streak of “extraordinary global temperatures” during which surface air temperatures averaged 1.48C above preindustrial levels.

The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of datacenters and cryptocurrency mining, and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by Donald Trump’s administration were not significant factors in the increase because they were only put in place this year, the study authors said.
