Latest Lonnie Thompson Stories
A glacier in Peru has been found to be shrinking as a result of warmer temperatures. Scientists have previously asserted that less snowfall was a key factor in the shrinking of this particular ice cap.
Earth's tropical climate history has been revealed in unprecedented detail – year by year, for almost 1,800 years – by two annually dated ice cores drawn from the tropical Peruvian Andes.
Researchers are beginning their analysis of what are probably the first successful ice cores drilled to bedrock from a glacier in the eastern European Alps.
One of the worldâ€™s foremost experts on climate change is warning that if humans donâ€™t moderate their use of fossil fuels, there is a real possibility that we will face the environmental, societal and economic consequences of climate change faster than we can adapt to them.
Glaciologists who drilled through an ice cap perched precariously on the edge of a 16,000-foot-high Indonesian mountain ridge say that the ice field could vanish within in the next few years, another victim of global climate change.
American glaciologist Lonnie Thompson has spent decades on glaciers drilling ice cores and has never come across a situation that is now occurring on top of Puncak Jaya -- a three-mile high glacier located in the Sudirman Range in the western central highlands of Papua province, Indonesia.
The majestic snow-capped summits of Africaâ€™s Mount Kilimanjaro are melting quickly â€” so quickly, in fact, that the ancient mountainâ€™s ice sheet could completely disappear within 20 years.
Researchers spent two months this summer high in the Peruvian Andes and brought back two cores, the longest ever drilled from ice fields in the tropics.
Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate.
Roughly 2 billion Asians will experience water shortages in the coming decades as global warming diminishes glaciers on the Tibetan Plateau, scientists warned on Friday.
