What was the hottest year on record?

Explanation:
Global temperatures reflect a long-term upward trend driven by increasing greenhouse gas concentrations, with year-to-year variations caused by natural fluctuations. The idea behind calling a year the hottest on record is that, when scientists average temperature across the globe for that calendar year, it exceeds all previous years in the instrumental record. In the most recent full year, analyses from multiple independent agencies show the global mean surface temperature reached an all-time high relative to pre-industrial levels. This means that the latest year stands out not just as a single warm instance, but as the warmest overall when all measurements are compiled and compared. The rise fits the sustained warming pattern over decades, with natural variability sometimes boosting warmth and other times dampening it, but the long-term trend pushes the latest year past the previous record holders. Earlier warm years, such as 2016, 2020, and 1998, were among the top tiers, but ongoing warming has raised the baseline, allowing the newest year to surpass them.
