How else will those intent on achieving a "New World Order" and/or the "One World Government" that they desire get it done? They must come up with some massive global issue that threatens all of human kind to gain our complacency and get us to fall into line and convince enough people in power to help them. And others are more than willing to personally capitalize on the effort and rake in all that lovely money that they use for theories and 'scientific evidence' in order to make the gullible and uncurious willingly complicit in the scheme.
The process is to gradually confiscate or remove our access to our resources and personal wealth and slowly, one by one so we don't really notice and/or are not alarmed, take away our individual liberties. Until one day we realize we are no longer a free people in control of our own destinies.
So when the opportunists are no longer able to capitalize in any way on the whole global warming schtick, they will quickly move on to something else to use for their purposes.
On what do you base all these ideas?
You would have to have tens of thousands of scientists from every nation on the planet (ie, with lots of different political viewpoints) all engaged in the same conspiracy (to form a New World Order, you claim) and not one has ever been caught or confessed to their actions. Every other climate scientist - the ones who USE that data for their own work would have to either also be in the conspiracy or be perfectly fooled by these supposedly manufactured data because THEY NEVER COMPLAIN. Your suggestion is simply meritless nonsense.
Right wing paranoid nonsense is what you've got.
