You lost. The IPCC's first assessment report was completed in 1990 and the scientific part disclaimed any certainty about human enhanced warming - so how could Exxon researchers been certain many years before that? Maybe you think Exxon's researchers are head and shoulder better than the rest of the worlds.

In Chapter 7 of the full report from 1990, the IPCC noted: “The evidence points consistently to real but irregular warming over the previous century. A global warming of larger size has almost certainly occurred at least once since the end of the last glaciation without any appreciable increase in greenhouse gases. Because we do not understand the reasons for these past warming events, it is not yet possible to attribute a specific proportion of the recent, smaller warming, to an increase of greenhouse gases” (emphasis added). In case anyone missed the message, in Chapter 8, the IPCC delivered an implicit rebuke to James Hansen, the excitable NASA scientist, who had told the Senate two years earlier, in 1988, that global warming had begun.

[ So how did Exxon KNOW all about climate catastrophe 13 years BEFORE this? ]

The IPCC wrote: Because of the many significant uncertainties and inadequacies in the observational climate record, in our knowledge of the causes of natural climatic variability and in current computer models, scientists working in this field cannot at this point in time make the definitive statement: “Yes, we have now seen an enhanced greenhouse effect.”
