Latest news and stories about global warming in Portugal for expats and residents.
March was the second warmest on record in Europe and the fourth warmest globally since records began. The oceans are also close to reaching record warming levels.
In March, the world's oceans reached near-record heat levels, according to the European Copernicus observatory. This trend, combined with human-induced climate change, signals the likely return of the El Niño weather phenomenon. Climatologists fear that this could lead to new extreme heatwaves, as ocean temperatures continue to rise. The warming of the oceans contributes to sea-level rise, marine heatwaves that damage coral reefs, and more intense extreme weather events. Additionally, the Arctic sea ice reached its lowest winter extent on record, further highlighting the ongoing pressure on the global climate system.
A report from the World Meteorological Organization reveals the greatest energy imbalance ever recorded and confirms 2025 as one of the hottest years. 'Climate chaos is accelerating,' warns Guterres.
The increase in pollution from fossil fuels has substantially exacerbated climate change and made last year one of the warmest since records began.
Data show that 2025 ranked as the third warmest year in the instrumental record, underscoring ongoing global warming trends.
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.
The difference between the temperatures recorded in 2025 and 2024 (the warmest year on record) was minimal, confirming that the global warming trend continues, says a report from the European Copernicus programme
Copernicus data indicate that 2025 was the third-warmest year on record.
The world will shoot past the Paris climate agreement's lower target by 2030, data shows.
Thousands of glaciers have disappeared in recent decades and, as the world continues to warm, they are expected to vanish at an ever-increasing rate. A new study gives an idea of how quickly this could happen, and it's frightening.
An international study calculates the thermal energy the ocean absorbed last year: it is 37 times greater than the world’s total energy consumption in 2023.
Climate change, exacerbated by human behaviour, made 2025 one of the three warmest years on record, according to scientists.
