Measuring climate change in the Pyrenees

Various schemes are being used in the mountains to measure the effects of global warming, such as changing animal habitats, growth of regional flora, temperature of lakes. All the data are being collected annually, or even quarterly in some cases.
The most striking results are in the shrinking of glaciers. The Ossue ice field has lost over 112 metres in length and 16 metres in depth since measurements started in 2001. Pierre Rene of an organisation called Moraine says that the glacier has receded by 60% in the last 100 years.
His picture shows how it has changed in the last 15 years.
