What's concerning is that people conflate the science that the earth is warming with the "non-science" that some catastrophic event is looming on the horizon if we don't stop that warming. The first is a testable hypothesis. The latter, when you consider the complexity of modeling climate and ecology, is at best no different than stock picking. That's why I disagree with the notion that climate skeptics are intellectually insincere in questioning climate change; whether they are right or not, there is a possibility this could be the next eugenics-like pop junk science where we are told we should make sacrifices because of some purported "theory".
