Global warming is not at all caused by humans, vehicles, factories or the like. There are many reasons for introducing global warming to the world. One of them is to increase fear in the population. Another is to introduce the global tax (the money actually goes to fund the North American Union). Another reason is to introduce the green agenda, which is nothing more than a hoax. Example, Fluorescent light balbs are very unhealthy.
The scale of deceit is absolutely unbelievable. Other giant frauds include the banking system, The media, news networks, and obviously Judaism, Christianity and Islam. For more info read the book The Biggest Secret by David Icke, you can find it anywhere for free.
HAIL SATAN!
