2024, the warmest year on record: what does passing 1.5°C mean?
A single record year is not the same as missing a long-term goal, but it is a clear warning.
The record
The World Meteorological Organization (WMO) confirmed that 2024 was the warmest year in a 175-year observational record, with global mean surface temperature about 1.55°C (±0.13) above the 1850–1900 pre-industrial average.
Has the Paris goal collapsed?
Not yet. 2024 was likely the first calendar year above 1.5°C, but the Paris Agreement goal is assessed over long periods, usually decades, not a single year. Still, it is a clear sign that we are approaching the limit.
What it means for our region
Hot, dry cities are especially sensitive to heatwaves and water scarcity, so climate-responsive design, tree planting and water management matter twice as much.
What can be done?
Cutting emissions is the fundamental solution, and adaptation is a necessary parallel track: more shade in streets, more energy-efficient buildings and careful water use.

Questions and practical notes
Adapting to heat
- Insulate roofs and windows to reduce air-conditioning load.
- External shading works better than internal curtains.
- Drink water regularly and avoid outdoor exertion at midday.
- Learn the signs of heat exhaustion: headache, dizziness and nausea.
Frequently asked questions
Does one year above 1.5°C mean Paris failed?
Not necessarily; the goal is measured on long-term averages, but a single year is an important warning.
What is the urban heat island?
Cities being hotter than their surroundings because of asphalt, concrete and lack of shade.
Where can I follow the data?
In WMO reports and national meteorological centres.
