I found it interesting to compare how the different search engines are treating the term "climategate." If you type "climategate" into Google, the search results are: 11,600,000. If you type the same term into the Microsoft Search Engine Bing the search results are 50,900,000.
Bing suggested "climategate" straight up, while Google required that I type in the full phrase, at no time did Google suggest the term "climategate."
If you type "global warming" into Bing the search results are: 13,600,000. Goggle search results are: 10,200,000. In all cases, Bing or Google, the term "climategate" now exceeds the search results for "global warming."
