They are the images that made us sit up and take notice. As world leaders gather for Cop27, these pictures prove that global heating isn’t a distant possibility – it’s already here
For a week in July 2018, a giant 100m-tall iceberg loomed over a tiny village on the west coast of Greenland. Villagers were evacuated, and the world watched in suspense: if a chunk of the 10m-tonne iceberg had broken apart or “calved”, it would have caused a tsunami and obliterated the settlement of Innaarsuit. Eventually, it drifted away from the shore – but as glaciers melt, we can expect to see more masses of ice breaking off and floating dangerously close to land.
