2025 Among the Top 3 Hottest Years in History, Emphasizing the Impacts of Climate Change
The World Meteorological Organization has announced that 2025 has entered the ranks of the three hottest years recorded since the monitoring of temperatures began 176 years ago, continuing an unprecedented streak of rising global temperatures.
The report noted that the last 11 years have been the hottest ever recorded, as ocean temperatures continue to rise steadily. According to the organization’s scientific analysis, the global average surface temperature in 2025 exceeded 1.44 degrees Celsius compared to the period from 1850 to 1900.
Two out of eight datasets classified this year as the second hottest on record, while the remaining six marked it as the third hottest. All datasets agree that the last three years (2023–2025) are the hottest, with an average exceeding 1.48 degrees Celsius above pre-industrial levels, and they confirm that the last 11 years, from 2015 to 2025, are the hottest since record-keeping began.
Professor Celeste Saulo, the Secretary-General of the organization, affirmed that despite being affected by the La Niña phenomenon, which typically cools temperatures, 2025 witnessed a record increase due to the accumulation of greenhouse gases. She added that these increases have contributed to the intensification of extreme weather events, such as heatwaves, heavy rainfall, and tropical cyclones, highlighting the importance of developing early warning systems to address climate risks.
Saulo emphasized that monitoring climate globally has become more critical than ever, stressing the need to ensure the accuracy and reliability of climate data and its accessibility for everyone to take appropriate action.
