Barring a seriously crazy shift that plunges us quickly into an especially cold winter, 2012 will likely go down as the hottest year on record in the United States. More importantly, this broken record is part of a larger pattern that affects the whole world—record-breaking high temperatures are becoming, themselves, a bit of a broken record. On a global scale, counting average land and water temperatures, 2012 is (so far) the 11th warmest year on record—almost a full degree hotter than the 20th century average. Of the 12 warmest years on record, all of them have happened since 1998 (and the top 20 is made up of years since 1987).
Over time, that kind of long-term trend takes a toll. But for those of us who are lucky enough to live with relatively high levels of wealth, air conditioning, supermarkets, and all the luxuries of modern life, that toll is not always obvious. Sometimes, you have to look a little deeper to see how climate change is already affecting the American way of life.
So, what's climate change ruining today? How about electricity generation? Juliet Eilperin at The Washington Post has a story about how a consistent trend of high temperatures and drought has affected water reserves, and how those diminished reserves affect our ability to produce electricity.
Electric generation accounts for 40 percent of water use in this country, and that's not just talking about hydroelectric power plants.
... low water levels affect coal-fired and nuclear power plants’ operations and impede the passage of coal barges along the Mississippi River.
Warmer and drier summers mean less water is available to cool nuclear and fossil-fuel power plants. The Millstone nuclear plant in Waterford, Conn., had to shut down one of its reactors in mid-August because the water it drew from the Long Island Sound was too warm to cool critical equipment outside the core. A twin-unit nuclear plant in Braidwood, Ill., needed to get special permission to continue operating this summer because the temperature in its cooling-water pond rose to 102 degrees, four degrees above its normal limit; another Midwestern plant stopped operating temporarily because its water-intake pipes ended up on dry ground from the prolonged drought.
