[...] ...she admitted that there was indeed a serious mistake in her Science essay. According to Oreskes, her study was not based on the keywords "climate change," but on "global climate change" [yet her paper is clearly titled: The scientific consensus on "climate change" not "global climate change"] Her use of three keywords instead of two reduced the list of peer reviewed publications by one order of magnitude (on the UK's ISI databank the keyword search "global climate change" comes up with 1247 documents) [...] The results of my analysis contradict Oreskes' findings and essentially falsify her study: Of all 1117 abstracts, only 13 (1%) explicitly endorse the 'consensus view'. [...] 34 abstracts reject or doubt the view that human activities are the main drivers of the "the observed warming over the last 50 years". 44 abstracts focus on natural factors of global climate change."
