glaciers
Affirmation iconoclaste que viennent étayer de très sérieuses études au coeur des Alpes : ces paysages qui nous paraissent aujourd’hui si naturels ont bel et bien été modelés et remodelés par les variations du climat et l’action millénaire de l’homme.

Twenty-six papers form a summary of research on glacial history, paleoclimatology, biogeography, ecosystem disequilibrium. Focus is on detailed chrono-stratigraphic, glacial geologic, and vertebrate paleontologic problems.

There is mounting evidence that climate change is triggering a shrinking and thinning of many glaciers world-wide which may eventually put at risk water supplies for hundreds of millions - if not billions - of people. Data gaps exist in some vulnerable parts of the globe undermining the ability to provide precise early warning for countries and populations at risk. If the trend continues and...
November 25, 2008 it was reported that geography coupled with high levels of poverty and population density has rendered South Asia especially vulnerable to the impacts of climate change. Speaking ahead of the United Nations Climate Change Conference in Poznan, Poland on December 1-12, 2008, Richard Damania, World Bank Lead Environmental Economist for the South Asia Region said the region...
Earth Under Fire: How Global Warming is Changing the World is a comprehensive look at the world wide effects of climate change. In dramatic photographs, maps and quotes from world climate science leaders, this one-of-a-kind book shows how the earth is being changed right now. The book illustrates on-going shifts from weather extremes and melting glaciers to disruptions of animal migration and...
Climate change is a reality today, and some of the best evidence comes from mountain areas: over the last century, glaciers in the European Alps and the Caucasus Mountains have shrunk to half their size, while in Africa only 8 percent of Mount Kenya's largest glacier remains. If current trends continue, by the end of this century many of the world's mountain glaciers, including all those in...
Climate scientists agree that the world’s climate is changing. The effects of global climate change will pose many challenges to the environment, economies, and communities of both California and Nevada over the coming decades. For example, by mid-century spring snowpack in the Sierra Nevada is projected to decline by 25 to 40 percent. Toward the end of the century, losses could reach 75...
Climate change will affect water availability differently in Europe - likely a large decrease in Southern Europe, while an increase in the North. However, the largest increases will be felt where very few people actually live - above 60°N, whereas large populations will be affected by shortages. Indeed, if climate change can be thought of as another 'consumer' of water, in some countries...
This study, prepared in close cooperation with and supported by the United Nations Environment Programme Regional Office for Asia and the Pacific, investigates the impact of climate change on glaciers and glacial lakes in two major glacial hotspots in the Himalayas: the Dudh Koshi sub-basin in the Khumbu-Everest region in Nepal, and the Pho Chu sub-basin in Bhutan. The focus was on changes in...
