Although it been said for the past 30 years that global warming is a REAL issue, governments and big business still continue to ignore it. Some scientists even say its a natural process (which is partly true, we are on a natural warming cycle, but its the speed of our warming that shows it might be something more then just a natural process [greenhouse gases]).
Well, NASA did a study and apperently they now believe that green house gases are a real issue. Maybe, because most people feel NASA is the smartest of the smart (which might be true), someone will finally admit it's and issue and do something about it.
Only time will tell now.
