According to the Copernicus Climate Change Service (C3S), January 2025 was the warmest January on record, with an average global temperature of 13.23 °C, which is 0.79 °C higher than the average for the period 1991–2020. This temperature is also 1.75 °C higher than pre-industrial levels.
Despite the expected cooling effect of the La Niña phenomenon, which is usually associated with lower global temperatures, this record was achieved. It suggests that natural climate patterns are unable to compensate for the effects of human-caused global warming. More on climate.copernicus.eu
