It's not only Brits that sweltered through last month. Globally, May 2025 was the second-hottest May on record, scientists at the the EU's Copernicus Climate Change Service (C3S) reveal.
The ice extent in January was down 498,000 square miles compared to the 1981 to 2010 average. That means the Arctic is now missing an area of ice six times the size of Wales.
