Salmon have survived for millions of years through far warmer climates but not a half degree Centigrade increase now? LOL
ScienceDaily (Nov. 21, 2008) University of British Columbia researchers have found a way to accurately predict the impact of climate change on imperiled Pacific salmon stocks that could result in better management strategies.
In 2004, unusually warm river temperatures and earlier entry into the Fraser River system contributed to the “disappearance” of 70 per cent of the Weaver Creek sockeye stock.
“In contrast, the Gates Creek sockeye stock, which have a higher thermal window, experienced few problems with the same high river temperatures that year.”
“This study shows that an increase over the past 50 years of 1.8 degrees Celsius in the Fraser River’s peak summer temperatures is too much too fast for *some* salmon stocks.” http://www.sciencedaily.com/releases/2008/11/081112124416.htm
