In the competition for the warmest year on record, 2025 narrowly missed the top spot, landing in third place according to data from the European Centre for Medium-Range Weather Forecasts (ECMWF). The year registered a temperature 1.47 degrees Celsius above the pre-industrial era average. Despite being slightly cooler than the hottest year, 2024, and just a fraction lower than 2023, the outcome was still a cause for concern, as highlighted by Florian Pappenberger, the ECMWF’s director general.
Various organizations, including Berkeley Earth and the UK Met Office, collaborated with the European data and all concluded that 2025 was the third warmest year on record. While falling short of the top position, experts emphasized that the year still brought about hazardous and fatal conditions affecting millions globally, with regional temperature records being shattered.
Europe experienced its third warmest year, with scorching summer temperatures impacting cities like Barcelona and the UK recording its hottest year. The intensified heatwaves were attributed to climate change, resulting in over 1,500 deaths in Europe, as per a rapid analysis by researchers.
In Canada, numerous heatwaves were linked to human-induced climate change, making extreme heat events more frequent across the country. Meanwhile, northwest Africa and central Asian countries faced unprecedented temperatures, leading to severe hardships for their populations, particularly women and young individuals.
Several regions, including Tajikistan, encountered record-breaking heatwaves even during typically cooler periods. The extreme temperatures had dire consequences, such as increased hospitalizations due to respiratory issues and notable glacial movements triggered by the rising temperatures.
Despite La Niña’s influence contributing to 2025 not clinching the top rank in global temperatures, experts warn that transitioning to a neutral status could pave the way for potential warming later in the year, driven by the onset of El Niño. The urgency to reduce greenhouse gas emissions was underscored as a crucial step to mitigate the escalating climate crisis.
Renewable energy investments were deemed crucial in steering the world away from fossil fuels, with experts emphasizing the need for a rapid transition to sustainable energy sources to address the pressing climate challenges ahead.
