Environmental Disaster Avoided

There is a good new about this environmental crisis. We dodged disaster with the ozone layer. There's a NASA study about the ozone chemicals from sprays and refrigeration. This was to play a game of what if. They say that by 2065 two-thirds of the protective ozone layer would have vanished and "the ozone hole covers the Earth." The CFC's which are long lived greenhouse gases would have pushed the world's temperature up an extra 4 degrees. DNA damaging ultraviolet radiation would have increased more than sixfold in mid latitudes like Washington. Fi -ve minutes in the summer sunshine would have caused a sunburn instead of fifteen. Normal midsummer UV levels arenow around ten or eleven would have soared to thirty. Summer thunderstorms in the Northern Hemisphere would have been much stronger. Here's what someone said. "It is a real horrible place," Newman told The Associated Press. The event was luckily avoided. After scientists raised warnings in the early 1970s later earning a Nobel Prize 193 nations agreed in the 1987 treaty called the Montreal Protocol to cut CFC emissions. The cochair said the study provides hope that the world can do the same thing on another looming but even harder to solve environmental problem which is global warming.
