Until today, the main problem in putting the system to practical use has been that meteor trails last only a few seconds. But the researchers believe they have found a solution. Once the voice has been converted into digital signals, the scientists have developed a way to compress them so that they can be transmitted in a few hundredths of a second. Since some half-dozen meteor trails are formed every second, they may well provide mirrors in the sky from which radio signals can be bounced to distant receivers over the earth’s horizon.

An increase in global water temperatures of only 2°F could raise the ocean level by two feet; melting ice caps could creating extreme flooding and changing the face of the landscape the world over…Low-lying cities, such as New York and New Orleans, would be the first to be affected.
