The Global Warming, Climate Change, whatever is BS intended to create a new industry of 'Carbon Credit Exchange'. The people pushing Global Warming also have invested heavily in the 'Carbon Credit Exchange' industry. Al Gore was planning on being a billionaire.
I think the money was a side benefit. Their true purpose for pushing globull warming is control. By controlling energy use you can control every aspect of peoples lives.
The so called scientists simply saw it as a great way to get grant money and go on taxpayer funded vacations.
