… Nearly two-thirds of the American public (63%) currently think global warming is happening, a percentage that has remained relatively stable over the past five years. Similarly, the percentage of the public who think that if global warming is happening, it is mostly human caused (52%) has also remained relatively unchanged.
One reason these numbers have been stable in recent years may be because most Americans are simply not hearing or talking about the issue. CONT.
