Global warming
Global warming is occuring but is also a natural cycle the earth goes through every few hundred thousand years (as shown by collected ice core data). The theory is based on poor sceince and data mining to show global warming is our fault, volcanoes on the other hand release tons mor carbondioxide than we have ever produced. So many jobs rely on the fact that global warming is our fault that we cant admit that we were all wrong. *Rant over*
