Climbers have a key role to play in highlighting global warming | Ed Douglas | Comment is free | The Guardian

Yet climbers also know mountains are always changing. It's in their nature. Glaciers in the Alps started retreating in the 19th century. Gigantic rock falls reported in recent years aren't new. Postcards from the 1930s of the Eiger's notorious North Face reveal that in some summers it looked as rocky and ice-free as it does now. Some of my more sceptical climbing friends say it's too easy to attach the phrase "climate change" to everything that happens in the entropic world of the high mountains.
