Would you advocate flagging all posts about global warming, period? Or just about skepticism?

All of them.

Would you advocate flagging all posts about science, or just scientific matters that are controversial?

Neither. Just the ones that are political.

Have you indeed concluded that all posts about global warming are 'political' rather than 'scientific'? Possibly true for the majority of such articles, but it would be nice if there was somewhere that the small remainder could be discussed in a scientific but non-political manner.
