This is a new thing that pseudo-scientists and fellow travelers are using, the meta-meta-study. It's either taking a bunch of studies and using them to paper over the problems with your own pet theory. Or it is death by a thousand paper cuts, with more and more 'me too' studies and rolling them together to support your own pet theory.
This is how we get memes like 97%, which is either some survey of some small group on an email list or a bunch of grad students picking, and more importantly excluding, papers that match a word search for global warming. Whether that is scary run away global warming or just noticing that we are coming out of an ice age doesn't seem to make a distinction for these people. Pointing that out gets a response that implies you are directly responsible for all of the carbon pollution in the world.
The upside is that they will probably block you if you dare mention that the greenhouse effect is logarithmically challenged.
