According to Copernicus, last year marked the third-warmest on record, with the past 11 years being the hottest overall. In 2025, global temperatures were approximately 1.47 degrees Celsius above preindustrial levels, primarily due to greenhouse gas accumulation from fossil fuel combustion. Despite international efforts like the Paris Agreement, temperatures have exceeded the 1.5-degree threshold for three consecutive years, highlighting urgent climate action needs. The situation is compounded by rising U.S. emissions and significant climate-related financial losses, with 23 events causing over $1 billion in damage last year.
