In many issues like this, my opinion is formed automatically without my conscious will or any kind of deliberate reasoning. I don't have opinions on highly technical issues I don't really care about, but on highly publicized issues like global warming it's hard for me not to develop any kind of preference to one direction or another. I had a certain feeling about global warming before I even knew enough about all the relevant facts and the science behind it, and this feeling was probably formed using very straightforward subconscious heuristics. So the question then is not "should I form an opinion on this", but rather "should I trust my gut feeling enough to call it an opinion and make it a small part of my identity" or "should I investigate this more to get a better feeling on the subject".
But this is just me, I'm not sure how other people's minds work. So do you mean you don't have even a slight preference to either direction? Or do you mean that this preference is not on such a firm ground that you should pay attention to it?
I don't have even a slight preference to either direction, but this is the result of a deliberate attempt at deprogramming, noticing beliefs that I can't back up and that appear to originate in downstream-from-politics status concerns and trying to remove them: I grew up with a vague sense that 'climate deniers' were stupid and inferior, but 1) vague senses are worse than zero information, 2) I grew up with other vague senses that turned out to be totally wrong, 3) the vague senses I grew up with are mostly historically recent enough [this one included, of...
Note: Please see this post of mine for more on the project, my sources, and potential sources for bias.
I have written a couple of blog posts on my understanding of climate forecasting, climate change, and the Anthropogenic Global Warming (AGW) hypothesis (here and here). I also laid down the sources I was using to inform myself here.
I think one question that a number of readers may have had is: given my lack of knowledge (and unwillingness to undertake extensive study) of the subject, why am I investigating it at all, rather than relying on the expert consensus, as documented by the IPCC that, even if we're not sure is correct, is still the best bet humanity has for getting things right? I intend to elaborate on the reasons for taking a closer look at the matter, while still refraining from making the study of atmospheric science a full-time goal, in a future post.
Right now, I'm curious to hear how you formed your views on climate change. In particular, I'm interested in answers to questions such as these (not necessarily answers to all of them, or even to only these questions).
