Roundup: Methane Production, Himalayan Dams and Postcards for a Swiss Glacier

Evidence from Beneath a Temperate Glacier

From Nature: “Contemporary glaciers and ice sheets are rarely accounted for as methane contributors through field measurements. Here, we present direct field-based evidence of methane production and release from beneath the Icelandic glacier Sólheimajökull.”

The Race to Dam the Himalayas

From The New York Times: “More than 400 dams are under construction, or planned for the coming decades, in Bhutan, India, Nepal and Pakistan; at least 100 more have been proposed across the Chinese border in Tibet. If the plans come to fruition, this will be one of the world’s most heavily dammed regions. But these projects will aggravate international tensions. They carry grave ecological risks. To understand why their backers cast caution aside, it helps to look to history.”

Shrinking Swiss Glacier Gets a Climate-Change Postcard

From Reuters: “The Alpine glacier [was] the site of a publicity stunt on Friday: the creation of what organizers say is the world’s largest postcard. Climate change activists hope it will convince more young people to get involved in keeping rising temperatures in check. In all, 125,000 postcards with messages against climate change and sent by young people from all over the world have been assembled around 3,400 meters up on the Jungfraufirn, the upper reaches of the Aletsch glacier.”
