From Field and Stream:

A World Without Trout
by George Reiger

As the temperature rises the salmonids may say good-bye.

Smallmouth bass replace char at the Arctic Circle? Peacock bass and tilapia edge out largemouth bass and crappies in the Lower 48?

If water temperatures keep rising, such implausibilities could eventually happen. According to a recent report by the Natural Resources Defense Council and Defenders of Wildlife, unless something is done to reverse the trend, trout and salmon are already doomed in many of the rivers and streams where they presently thrive. Indeed, except for coldwater pools located directly downstream from high dams, trout fishing in California, the South, and even the Northeast will be mostly a matter of memory.

Turn on the tv, Kill a fish?
The primary cause of this warming-water trend and coldwater fishery decline is utility-generated carbon dioxide. Although transportation produces whopping amounts of atmospheric pollution, fossil-fueled power plants alone generate 40 percent of the carbon dioxide in our air.

Consider these additional facts provided by my mid-Atlantic utility, Conectiv: One megawatt of energy is needed to power about 1,000 typical homes. Yet each megawatt generates 1,544.8 pounds of carbon dioxide per hour of operation.

Each Conectiv megawatt also produces three other unwanted by-products: sulfur dioxide (12 pounds per hour), nitrogen dioxide (3.5 pounds per hour), and mercury (no numbers provided). Sulfur dioxide and nitrogen dioxide combine and react to form acid rain, and nitrogen dioxide by itself reacts to form ground-level ozone, an unhealthy component of smog.

As for mercury, its so efficiently bioaccumulated that many gamefish at the top of the aquatic food chain have mercury concentrations over 1 million times higher than the surrounding water. Forty states have issued fish-consumption advisories for popular freshwater and marine fishes whose flesh has mercury levels up to 65 times above the Environmental Protection Agencys safe limit.

Hotter and Hotter
While carbon dioxide is not such an obvious hazard to our collective health, its the principal culprit behind the worlds warming trend. Last year was the second hottest year on record, just behind 1998. Since 1990, America has experienced nine of its 10 hottest years. And although natural causes may play a role, its significant that global temperatures increased an average of 1.1 degrees Fahrenheit during the past 100 years of industrial expansiona far faster rate than can be extrapolated for the previous 1,000 years.

If supplying electricity to 1,000 typical homes produces over 1,500 pounds of carbon dioxide per hour, the amount generated by the nations millions of houses, apartments, and businesses during the course of a single week of economic activity is truly mind-boggling. Thats why the NRDC and Defenders of Wildlife tried to put the numbers in some perspective by linking them to the decline of certain coldwater fishes.

Although the projected increases in water temperature vary by location, the continental average is .7 to 1.4 degrees by 2030, 1.3 to 3.2 degrees by 2060, and 2.2 to 4.9 degrees by 2090. In addition, by the end of this century, summertime temperature peaks will last four weeks longer than they do at present.

I hate winter anyway. Just think, I wont have to head south in the winter. I
can jet-ski the year around up North. And, have you seen how them peacock

Not that I agree with troll-baiting, but...

Me thinks that lad's a few snowflakes short of a snowball...
