Really not too many here on the pro-warming side here who can articulate which things are soundly established and which things have been pulled out of the #### of some rabid advocate pushing an agenda.
Can anyone here do that, based on their own knowledge of the subject? Some might think they can, but are they
self-calibrating properly?
Climate science is hard. Developing any genuine expertise on the subject takes an awful lot of work.
I consider myself better informed on the subject than the average person, but I know that I'd be way out of my depth trying to form conclusions on the topic based on the science itself -- the data being collected and analyzed, and so on.
But that doesn't mean that we can't have a decent idea about which side is likely to be right. Many of the details are uncertain, but on the basic point of whether humans are causing an increase in global temperatures, there is a strong scientific consensus
of the sort that has hardly ever been wrong. It is rational to believe that the consensus is very likely to be right this time as well.
