CBC: Kootenay Glaciers Shrinking At 'huge' Rate, Researcher Warns

Posted on Thursday, October 26 at 09:08 by bracewell
From 1986-2000, the glaciers diminished in total size by 16% - with the Slocan losing 47% and the Bull losing 60% of their total ice area - a loss of approximately 67 cubic kilometres of permanent ice. This increased the streamflows by an average of 700 to 800 cubic metres per second between 1986 and 2000. This cold runoff accounts for 10-20% of annual flows and up to 50% of some years’ late summer flows.

Tree rings, glacier and other evidence tell us that prolonged droughts were more common in the 1700s and 1800s than in the last century, suggesting that we’ve recently lived through a period of relatively drought-free climate.

Changes in glacier and snow melt are likely to result in reduced summer streamflows which, coupled with increased summer evaporation and transpiration, is expected to reduce soil moisture leading to increased drought impacts.

Climate change has the potential to disturb water allocations between hydropower, flood control, and industrial, agricultural, municipal, environmental and recreation use - creating important implications for management of transboundary waters shared with the United States.

    Note:
    This study ran from 1986-2000 - melt rates and the associated problems has most likely increased since then.

    According to the government, they will have a solution to this problem by 2050. No rush. After all, this isn't anti-terrorism legislation.
