Climate change is making extreme weather events, such as torrential rain and heatwaves, more frequent. Experts warn the trend will continue as long as the world keeps burning fossil fuels.
A new study shows the number of people exposed to extreme heat could double in the coming decades. The greatest impacts will be felt this decade as the world nears the 1.5°C threshold.
A new study warns that, by 2050, extreme heat could expose almost half of the world’s population to dangerous conditions — and that global preparedness is inadequate. The analysis projects marked increases in heatwave frequency and intensity, with disproportionate impacts on urban populations, workers, older people and lower-income communities, creating risks for health, wellbeing, labour productivity, displacement and sustainability. Authors call for urgent mitigation (deep emissions cuts) alongside targeted adaptation: heat-resilient infrastructure, equitable access to cooling and water, early-warning systems and planning to reduce inequitable risks.
The planet's global temperature remains very high, and meteorological data show that last year was the third warmest on record, with 2023 and 2024 setting record highs.
The year 2025 was the third warmest on record and the third consecutive year in which temperatures remained above the 1.5°C limit, a European scientific centre said today.
Data indicate that 2025 ranked among the three warmest years in the historical record, continuing the trend of rising global temperatures.
Climate change, exacerbated by human behaviour, made 2025 one of the three warmest years on record, according to scientists.
The Ministry of the Environment will proceed with the nationwide installation of a network of “Green Islands”, a new preventive approach to mitigate the harmful effects of extreme weather events.
