You make an historical observation when describing the time frame between Hansen (1999) and Oreske (2007) and suggest some search strategies. I found it interesting to do an "old school" search on the subject. That is, try searching the phase, "greenhouse effect." The third result I returned, after a couple of relevant middle school lesson plans, was from DOE in the early 90's, see http://www.osti.gov/bridge/servlets/purl/10192250-PTINyH/10192250.PDF Also, more history in the sprint of a search on James Hansen's name, try a search on C.D. Keeling. The first result, "Atmospheric CO2 records from sites in the SIO air sampling network," gives an overview of CO2 measurement over nearly 50 years.
