I would describe myself as agnostic on the topic simply because I haven't done enough personal research, but the devout belief that many people have in human-caused global climate change is really off putting, primarily because it's hubristic in so many ways: that our presence and actions are harming a 4.5 billion year planet in the span of a few decades; that our models are that good; that our data is that good; that our analysis and conclusions are undoubtedly true, etc. My inner skeptic just freaks out.
