From the Exxon Secrets site: "Finally. After years of denying its role in the campaign of climate denial, Exxon has revealed a dirty secret, that it has and likely still is DIRECTLY funding junk scientists."On page 28 of Heat: How to Stop the Planet From Burning, George Monbiot writes "By funding a large number of organizations, Exxon helps to create the impression that doubt about climate change is widespread." On page 40, Monbiot continues " the people who have been paid by Exxon are ....members of a public relations industry, which begins with a conclusion and then devises arguments to support it." Nota bene: if the evidence you are using to deny climate change comes from an organization funded by Exxon , it is not valid scientific evidence. It is propaganda created by Exxon!
