Google's "Code of Conduct" says:
Code of Conduct
PrefaceGoogle is a publicly traded company and if I were a shareholder I would not be pleased about intentionally biasing results when the company states its results are "unbiased." Sounds like potential grounds for a shareholder lawsuit.
I have no idea whether Google losing my postings has to do with my stance on global warming (open-minded skepticism, but highly critical of the apocalyptic predictions from some pro-GW people) but now that I see they are apparently tinkering with other sites (Anthony's, Ann's) that express similar views, I'm going to start monitoring Google more closely.
