...rain forest is a self-perpetuating system in that water vapor from trees energizes rainstorms. Cut the trees and rainfall decreases, further drying a system that is not adapted to recovering from fire. Experts wonder if this is why denuded southern China has seen a decline in rainfall this century, and why West Africa has lost one of two rainy seasons. Looming over all rain forests is the threat of global warming caused by human emissions of greenhouse gases. Computer simulations suggest that the greenhouse effect will increase the frequency of drought in tropical areas...
Once the steam enter the building, it goes into a radiator, turns into water and gives off heat in the process--the same type of reaction that causes third degree burns from steam. When the water vapor contracts into a more dense state--from gas to liquid--it gives off energy in the form of heat. Once the steam condenses to water after it has served its heating purpose, it is sent back to the plant through the same system of underground lines and tunnels...
...tsunami (commonly called a tidal wave) hundreds of feet high, flooding the coastlines of surrounding continents. "Where cities stood," he said, "there would be only mudflats." A land hit, he calculated, would blast out a crater at least 30 miles across and throw up a blanket of dust and vapor that would blot out the sun "for weeks, if not months...
...quick response to the rare deaths, the NCAA elected to alter rules concerning weigh-ins and weight-loss techniques for the remainder of the season. The new rules imposed a ban on all "vapor-impermeable suits," and the use of what the NCAA calls a "hot room," defined as any room having a temperature of over 79 degrees Fahrenheit. These rules supplement the already-existing statutes banning the use of diuretics, laxatives, or self-induced vomiting. The NCAA will also attempt to establish an education platform, through which they hope to keep athletes aware of the dangers of pushing their...
...kids poured mercury all over everything"--including themselves, their clothing and carpeting--"and they breathed the vapor," says Dave Hall, the city's emergency coordinator. In one house the fumes, which accumulate near the floor, killed the family dog and caused health officials to rush several small children to the hospital. In that dwelling and others, emergency teams were tearing out carpets and floorboards. Investigators have recovered all but a few pounds of the mercury, and promise not to prosecute anyone who turns in more...
