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".
Insincere is comparing climate change to eugenics. Eugenics was purely a theory and promoted taking away people's right to have children (or in the worst cases, genocide). Climate change involves hard evidence that the world is warming and demands economic changes to mitigate.
Any policy debate is going to be far more complicated that any testable hypothesis and scepticism is healthy, but your comparison to eugenics is bullshit.
