For most people, deciphering the impact of rising temperatures on their everyday lives isn’t easy. Global warming of 1.5C or 2C on average is hard to imagine. To try and solve this problem, researchers at the Massachusetts Institute of Technology (MIT) have come up with an innovative new way to measure this real-life change and predict its long-term effects. Using data from 50 different climate models, they charted how the number of ‘outdoor days’ in various destinations around the world will go up or down by 2100. These ‘outdoor days’ refer to periods of 24 hours when temperatures are pleasan...

The climate crisis will reduce global income by about a fifth in the next 25 years compared to a fictional world that's not warming. That’s according to a new study which predicts people in the world’s poorest areas and those least responsible for heating the atmosphere will take the biggest monetary hit. Climate change’s economic bite out of incomes is already locked in at about $38 trillion (€35.6 trillion) a year by 2049, researchers at Germany's Potsdam Institute for Climate Impact Research (PIK) found. By 2100 the financial cost could hit twice what previous studies estimate. “Our analysi...

Last month was the hottest March on record, becoming the tenth record-breaking month in a row, scientists have said. The global air temperature was 0.73°C above the 1991-2020 average for March, according to the EU’s climate service, and 0.10°C above the previous high set in March 2016. It marks the tenth consecutive month where temperatures have been hotter than ever recorded for the respective time of year, after February also broke the old record by a tenth of a degree. “March 2024 continues the sequence of climate records toppling for both air temperature and ocean surface temperatures,” sa...

January, February and March are likely to have been Spain’s warmest first quarter since records began in 1961. National meteorological agency Aemet said on Tuesday that the average temperature in mainland Spain during the first three months of the year was 9.5C. That is 1.9C higher than the average for this time of year and 0.1C higher than the previous record set in 1997. Final data is still needed to confirm the record but the meteorological agency has said, as January and February were already very warm months, it believes the first quarter of 2024 was the warmest in history. Temperatures i...

We already know that 2023 was the hottest year on record by a significant margin. But a new report from the UN’s meteorological agency reveals how many other symptoms of climate change were off the charts last year. “Climate change is about much more than temperatures,” says the World Meteorological Organisation (WMO)’s secretary-general Celeste Saulo. “What we witnessed in 2023, especially with the unprecedented ocean warmth, glacier retreat and Antarctic sea ice loss, is cause for particular concern.” The WMO’s latest State of the Global Climate report takes stock of numerous indicators of t...

Lake Geneva, Western Europe's largest freshwater reserve, is facing a hidden crisis. Its water temperature is rising at an alarming rate - 4 to 5 times faster than the world's oceans. With average annual temperatures reaching a record 13.6 degrees Celsius, it is throwing the lake's delicate ecosystem into disarray. Fishermen see the impact of global warmingProfessional fishermen are seeing the consequences when they raise their nets. Some species are becoming more abundant or reproducing at different times while others disappear as the waters warm. "Here's the big winner of global warming... L...

Scientists have successfully modelled a climate tipping point that would plunge large parts of Europe into a deep freeze - and it could be closer than previously thought. Using a complex climate model, researchers from Utrecht University in the Netherlands simulated the collapse of an important Atlantic Ocean current which currently brings warm water north and keeps temperatures in Europe mild. An abrupt shutdown of this current would change weather worldwide with Europe suffering the most severe consequences. Melting ice sheets could cause its collapse - but when or how likely is it to happen...

Global warming has exceeded 1.5C for an entire year for the first time ever, according to the EU’s climate service. Humans are responsible for virtually all global heating in the last 200 years, scientists say. And 2023 was a year filled with extraordinary droughts, searing heatwaves and deadly rainfall. So what needs to be done to cool our planet? Can we still keep the Paris Agreement target alive and is it still possible to keep global warming from spiralling out of control? Why is 1.5C such an important threshold?The Paris Agreement target of limiting global warming to 1.5C is based on long...

January 2024 was the warmest January on record globally, the Copernicus Climate Change Service (C3S) has confirmed. Reporting on behalf of the European Commission, C3S has published its monthly climate update on the changes observed in global surface air and sea temperatures, sea ice cover and hydrological variables. All the reported findings are based on computer-generated analyses of data on atmospheric, land and oceanic climate variables. C3S reported an average surface air temperature of 13.14C in January 2024, which is 0.70C above the 1991-2020 average for January and 0.12C above the temp...

A handful of centuries-old sponges from deep in the Caribbean Sea could hold clues about the impact of human-caused climate change. They're causing some some scientists to believe that warming began sooner and has progressed more rapidly than previously thought. The researchers calculate that the world has already gone past the internationally approved target of limiting global warming to 1.5°C since pre-industrial times, hitting 1.7°C as of 2020. They analysed six of the long-lived sponges - simple animals that filter water - for growth records that document changes in water temperature, acid...
