2025 set to be among hottest years on record, UN scientists warn
2025 ranks as second or third warmest year with global temperatures 1.42°C above pre-industrial levels amid rising greenhouse gases, UN reports stress urgent climate action.
- On Thursday, November 6, the World Meteorological Organization reported that 2025 will rank as the second or third hottest year ever recorded, with January–August temperatures 1.42C above pre-industrial levels, releasing its State of the Global Climate report at the Leaders' Summit in Belém, Brazil.
- WMO scientists found rising greenhouse gases and ocean heat content this year, with record greenhouse gas concentrations locking in future warming and ocean heat at its highest recorded level.
- Arctic observations show record-low sea ice after the winter freeze, Antarctic sea ice extent tracked well below average, and global glaciers lost about 450 gigatonnes of ice in 2024.
- The WMO report said limiting near-term warming to 1.5C is now unlikely without overshoot, but WMO Secretary-General Celeste Saulo said `the science is equally clear that it's still entirely possible and essential to bring temperatures back down to 1.5C by the end of the century`.
- With COP30 opening on November 10 in Belém, the past 11 years have been the warmest since records began, and Blair Trewin said `Ocean heat content is looking at what's going on not just at the surface of the ocean but in the top 2,000 metres of the ocean`.

Belém. The year 2025 is one of the warmest ever recorded after more than a decade of high and unprecedented temperatures, although the trend can still be reversed with concrete measures, said the World Meteorological Organization (WMO) yesterday.
The series of exceptionally warm months continues in 2025, which will be the second or third warmest year on record, according to the World Meteorological Organization's (WMO) report on the state of the global climate.
‘Unprecedented streak of high temperatures’: 2025 set to be among top three warmest years, says World Meteorological Organization
The WMO report also stated that the period between 2015 and 2025 would have individually been the 11 warmest years in the 176-year observational record.
2025 to be among warmest years on record
An alarming streak of exceptional temperatures has put 2025 on course to be among the hottest years ever recorded, the United Nations said Thursday, insisting though that the trend could still be reversed. While this year will not surpass 2024 as the hottest recorded, it will rank second or third, capping more than a decade of unprecedented heat, the UN's weather and climate agency said, capping more . Meanwhile concentrations of greenhouse gase…
