De verdwijnende gletsjers van de Himalaya

Update: [...] two recent studies published in top scientific journals (more here and here) suggest that in the Himalayas the rate of mass loss has been small and overestimated, and that [ ...] in the Karakoram range, the glaciers are actually slightly gaining mass [maar deze gletsjers zijn atypisch omdat er veel rotsen op liggen en ze worden gevoed door lawines van diverse bergflanken; K]. [...] it is not surprising that there are regional variations [...]. Such variability should not, however, distract from the broader and more important story unfolding, which is one of profound and likely irreversible changes to global land and sea ice cover. Taken as a whole, the evidence for sustained changes to the cryosphere is clear. [einde update]
For centuries, glaciers have inspired awe and wonder. The idea that human assault might ever triumph over such powerful features of our natural landscape seemed almost unimaginable. But now climate change is disrupting the ecological balance of the Tibetan Plateau and the mighty glaciers of the Himalaya are, in fact, disappearing.
Rivers of Ice: Vanishing Glaciers of the Greater Himalaya showcases the work of photographer and mountaineer David Breashears, who with Glacier Research Imaging Project (GRIP), has retraced the steps of renowned mountain photographers of the past century to recapture images of these mountains and their glaciers from exactly the same vantage points. Rivers of Ice displays his recent photographs alongside the corresponding historic images, revealing the alarming loss in ice mass that has taken place over the intervening years.
