Eurasia Review: Environmentalists and scientists have urged India and Pakistan to free the world’s highest battleground‎ of Himalayan Siachen glaciers from military forces to avoid devastating ecological disasters. “From human and environmental perspective, it is an expensive and tragic standoff on Siachen between two countries where either is too proud to back off unilaterally as [...]

NPR (by Richard Harris) : The Himalayas are sometimes called the world’s “third pole” because they are covered with thousands of glaciers. Water from those glaciers helps feed some of the world’s most important rivers, including the Ganges and the Indus. And as those glaciers melt, they will contribute to rising sea levels. So a [...]

New Scientist: As Arctic sea ice breaks apart, massive amounts of methane could be released into the atmosphere from the cold waters beneath. High concentrations of the greenhouse gas have been recorded in the air above cracks in the ice. This could be evidence of yet another positive feedback on the warming climate – leading [...]

India Today: Naysayers notwithstanding, new studies show that Himalayan glaciers are indeed melting possibly due to climate change. The rate of their melting is not as alarming as projected by the Intergovernmental Panel on Climate Change (IPCC) in 2007 but is significant enough to seriously impact water availability in Asia in future. The warning comes [...]

Science Daily: Several hundreds of millions of people in Southeast Asia depend, to varying degrees, on the freshwater reservoirs of the Himalayan glaciers. Consequently, it is important to detect the potential impact of climate changes on the Himalayan glaciers at an early stage. Together with international researchers, glaciologists from the University of Zurich now reveal [...]

Washington Post [YOKOSUKA, Japan] — To the world’s military leaders, the debate over climate change is long over.
