Liberals love to pretend the debate over global warming has been settled. To them, either you get behind every idea they have to save the planet from certain doom, or you’re a “denier” who doesn’t believe in science.
Of course, there are many people who believe in global warming; they just don’t see the need to panic yet. Some even think action needs to be taken, but believe any action should be given a thorough cost/benefit analysis to weigh its damage to our economy.
This sort of reasonable debate isn’t enough for liberals. Often, any argument against an environmental regulation is met with the retort, “the science is settled, 97% of scientists agree.”
