University of Leeds | News > Environment > Melting glaciers could speed up carbon emissions


Melting glaciers could be triggering a ‘feedback process’ that causes further climate change, according to new research.
An international research team led by the University has for the first time linked glacier-fed mountain rivers with higher rates of plant material decomposition, a major process in the global carbon cycle.
As mountain glaciers melt, water is channelled into rivers downstream. But with global warming accelerating the loss of glaciers, rivers have warmer water temperatures and are less prone to variable water flow and sediment movement. These conditions are then much more favourable for fungi to establish and grow. 
Fungi living in these rivers decompose organic matter such as plant leaves and wood, eventually leading to the release of carbon dioxide into the air. The process – a key part of global river carbon cycling – has now been measured in 57 rivers in six mountain ranges across the world, in Austria, Ecuador, France, New Zealand, Norway ....

India: Climate change and extreme development to blame for Himalayan tragedy


The disaster triggered avalanches, burst glaciers and flooded rivers, devastating villages, roads, bridges and hydro-electric power projects (HEPs), and sweeping away over 250 locals and workers.
While 69 bodies have been recovered so far, authorities have declared 135 people still missing as “dead” and the huge rescue operation is now a recovery effort.
At the time of writing, 21 bodies have been pulled from the slush-filled 2.5 kilometre-long tunnel at the state-owned National Thermal Power Corporation’s (NTPC) Tapovan-Vishnugad project site, where about 30 workers were feared trapped.
The NTPC has been fined about US$80,000 for causing environmental damage by violating muck disposal site maintenance standards in the Tapovan area. ....
