Hot enough to make ya think...

Ferocious Heat Maintains Grip Across the West
Published: July 23, 2005
PHOENIX, July 22 - A relentless and lethal blanket of heat has settled on much of the western United States, forcing the cancellation of dozens of airline flights, threatening the loss of electrical power, stoking wildfires and leaving 20 people dead in Phoenix alone in just the past week.
Officials of the National Weather Service estimate that more than 200 heat records have been broken in the West during the last two weeks. On Tuesday, Las Vegas tied its record for any date, 117 degrees. Reno and other locations in Nevada have set records with nine consecutive days of temperatures at 100 or higher. The temperature in Denver on Wednesday reached 105 degrees, making it the hottest day there since 1878. The highest temperature for the entire region during the heat wave has been 129, recorded at Death Valley, Calif.
The reasons for that are related to engineering. Aircraft manufacturers have customarily set temperature limits at which their planes can be safely operated. (The limits are lower at higher altitudes, as in the Rocky Mountains, and higher at lower altitudes, as in the desert that surrounds Las Vegas.) High temperatures mean aircraft engines must take in more air in order to create the greater thrust the planes need to leave the ground. But airplane makers also have limits on the amount of thrust that an engine can produce. If the engines exceed those limits, they may not perform properly. At that point, aircraft manufacturers advise, the airlines should remove weight from planes - either passengers or cargo - or, in the worst cases, not fly at all.
United Airlines canceled seven United Express flights out of Denver on Wednesday, when the record-tying temperature there exceeded the operating limit for the carrier's propeller planes, said a spokesman, Jeff Green. "It was just so extreme, and stayed on so long, that we had to cancel flights," Mr. Green said.
In Death Valley, meanwhile, the temperature never dropped below 100 degrees in two 24-hour periods.
Andy Bailey, a National Weather Service meteorologist in Las Vegas, said: "It's probably fair to say what just wrapped up was probably the most intense heat wave the city's ever seen. We had a string of four days where it was 115 or above."

Poll: Americans Say World War III Likely
By WILL LESTER, Associated Press
Those findings come six decades after the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. The war claimed about 400,000 U.S. troops around the world, more than three times that many Japanese troops and at least 300,000 Japanese civilians.
Six in 10 Americans said they think such a war is likely, while only one-third of the Japanese said so, according to polling done in both countries for The Associated Press and Kyodo, the Japanese news service.
"I feel like we're in a world war right now," said Susan Aser, a real estate agent from Rochester, N.Y.
Two-thirds of Americans say the use of atomic bombs was unavoidable. Only 20 percent of Japanese felt that way and three-fourths said it was not necessary. One-half of Americans approve of the use of the atomic bombs on Japan.
