Global Warming: Political hoax or Fact?

If the world doesn't make a step to at least reduce the main causes of global warming, like excessive CO2 from factories and car exhausts, I believe we'd be in big trouble. Thankfully, a few countries are stepping forward and made some rules to reduce the heat. I hope the rest follows. By this rate, I believe the scientist's prediction of the end of earth in year 3000 would be true.
