Glaciers

The most visual indication of climate change is the melting of mountain glaciers. The vast majority of the mountain glaciers of the world are melting back at astonishing rates (Fig. 11.4). This is happening all over the world. Figure 11.5 shows records of shortening of 20 glaciers around the world. Many of the glaciers have been melting back since the 1700s as a result of natural warming since the Little Ice Age. However, melting has accelerated in the past decades. The Snows of Kilimanjaro (see Further reading) are forecast to melt entirely by 2030, as are all the glaciers in Glacier National Park in the United States.
