Six months ago, IPSO upheld our complaint against the Telegraph for its article falsely claiming rail delays due to extreme weather were falling (they weren’t). Today, the facts are clear: 7,000 trains were delayed last year from floods alone. @roundourwayuk.bsky.social inews.co.uk/news/environ...

Myanmar earthquake: woman trapped for days pulled alive from the rubble
Brief moment of relief as rescue workers carry a woman from the rubble of a hotel in Mandalay after a five-hour operation * Myanmar earthquake: What we know so far A woman trapped beneath the remains of a hotel building for nearly 60 hours after a devastating earthquake struck Myanmar was pulled alive from the rubble on Monday, officials said, in a rare moment of hope for rescue teams scrambling to find survivors. Rescuers, many of them unequipped volunteers, have spent days trying to free people from buildings collapsed following Friday’s huge earthquake, which killed more than 1,700 people in the country and at least 18 in neighbouring Thailand.

🔴 2023 was also the driest year for global rivers in 33 years. 🌡️ Rising temperatures are speeding up the hydrological cycle, making it more erratic and unpredictable. 🔵 This means we’re increasingly facing extremes—too much water in some places and too little in others.
