It's Not Just Happening to Us...

Several years of dry winters and unusually hot summers have left Canada's subarctic regions in serious trouble, causing severe and worrisome desiccation of the regions' lakes.  After the exclusive study of 70 lakes near Old Crow, Yukon and Churchill, Manitoba it became apparent that most of the lakes had become less than a meter deep, with dead vegetation banking the shores.  The problem comes primarily from a decline in "melt-water" that usually supplies the lakes.  For example, from 2010 to 2012 the average winter precipitation in Churchill decreased by 76mm when compared to the average that had been recorded between the years 1971 and 2000.  "With this type of lake, precipitation in the form of snow represents 30% to 50% of the annual water supply," explained the study's lead author, Frederic Bouchard.  Clearly, a lack on snow fall will rapidly and drastically affect the water levels and viability of the lakes.  With several ecological and environmental concerns buzzing through the air researchers have become increasingly concerned, in addition to the realization that this decline has not been seen in the 200 years of its observation.  So folks, back here in the USA we surely are not the only ones feeling the pressure and concern associated with water resources and conservation.  Just one of the many issues concerning water around the globe.

  1. It is so unfortunate what is going on with the climate change. I think we should all start getting prepared and help in many ways we can, by replacing grass for artificial grass, re-use water at home and so many other things we can all help.
