Roundup: Canadian River Vanishes, Plants in the Himalayas and Pakistan’s Villages

Glacier retreat in Canada causes Yukon river to vanish.

From CBCNews: “It’s been the main source of water into Yukon’s Kluane Lake for centuries, but now the Slims River has suddenly slimmed down — to nothing. ‘What folks have noticed this spring is that it’s essentially dried up,” said Jeff Bond of the Yukon Geological Survey. ‘That’s the first time that’s happened, as far as we know, in the last 350 years.’ What’s happened is some basic glacier hydrology, Bond says — essentially, the Kaskawulsh Glacier has retreated to the point where its melt water is now going in a completely different direction, away from the Slims Valley. Instead of flowing north 19 kilometres from the glacier’s toe into Kluane Lake (and ultimately, the Bering Sea), that melt water is now draining eastward via the Kaskawulsh River towards the Pacific Ocean off the Alaska panhandle. It’s a reminder that glacier-caused change is not always glacial-paced.”

The world’s highest vascular plants found in Indian Himalayas.

From Microbial Ecology: “Upward migration of plants to barren [just below the snowl areas is occurring worldwide due to raising ambient temperatures and glacial recession. In summer 2012, the presence of six vascular plants, growing in a single patch, was recorded at an unprecedented elevation of 6150 m.a.s.l. close to the summit of Mount Shukule II in the Western Himalayas (Ladakh, India). Whilst showing multiple signs of stress, all plants have managed to establish stable growth and persist for several years.”

Local struggles in Pakistan show adaptations to glacier thinning.

From Erdkunde: “Framing adaptation as a process of assemblage-building of heterogeneous human and non-human [actors], two village case studies are investigated where glacier thinning has dried up a source of irrigation water, turning cropland into desert. While in the first case case, villagers were able to construct a new and extraordinary water supply scheme with the help of external development agencies, in the second case, several approaches to utilize alternative water sources over three decades were unsuccessful. An account of the adaptation assemblages shows how a diversity of actants such as individual leaders, community, external agencies, construction materials, landslides and geomorphological features play variable and contingent roles in the success or failure of adaptation efforts, thus co-defining their outcome in complex ways.”

As a Glacier Retreats a Major Water Source Dries Up

From CBC News:

“It’s [the Kaskawulsh glacier] been the main source of water into Yukon’s Kluane Lake for centuries, but now the Slims River has suddenly slimmed down — to nothing.

‘What folks have noticed this spring is that it’s essentially dried up,’ said Jeff Bond of the Yukon Geological Survey.

‘That’s the first time that’s happened, as far as we know, in the last 350 years.’

What’s happened is some basic glacier hydrology, Bond says — essentially, the Kaskawulsh Glacier has retreated to the point where its melt water is now going in a completely different direction, away from the Slims Valley.”

Rising Temperatures in National Parks Like Glacier Bay

From Climate Central:

“With such a wide variety of climates across the park system, the country’s 59 National Parks all have different challenges to manage in the changing climate. Some parks have experienced dramatic temperature changes, and these shifts can lead to water shortages (or too much water), ocean acidification, and species migration…. Glacier National Park — The number of glaciers has been cut in half since 1968, and the largest glaciers are expected to be gone within the next 15 years.”

Hosted by Greenpeace: Professional Pianist Plays on Glacier

From Greenpeacespain on YouTube:

“Through his music, acclaimed Italian composer and pianist Ludovico Einaudi has added his voice to those of eight million people from across the world demanding protection for the Arctic. Einaudi performed one of his own compositions on a floating platform in the middle of the Ocean, against the backdrop of the Wahlenbergbreen glacier (in Svalbard, Norway).”
