When one replaces their sense of skepticism with willful ignorance.An honest question here: Where is the line on denier vs skeptic? Where does one cross that line when it comes to global warming or climate change?
Those are all fair questions.It's obvious the Earth has warmed over the last 200-300 years (honestly, we can say more about the northern hemisphere than the southern). There's no doubt the CO2 concentration in the atmosphere has increased. It seems likely that man has contributed to that. CO2 is a known greenhouse gas. All makes sense. Doesn't the question mostly come down to one of several from whether the models are right, if their fudge factors (they all have them) accurately reflect the real thing, the amount of warming, how much man actually contributes to that, and maybe a few other questions? So are some of those not legitimate? Which question makes one a denier? Which one makes one a skeptic? I honestly want to know.
Think of it this way to draw the distinction. Working in health care, I am very skeptical of alternative medicine. Does that make me an alt-med denialist? Say you meet someone that is a Holocaust denialist. Would you consider him a skeptic?
