Three reporters from the online magazine, InsideClimate News, won a Pulitzer Prize in 2012 for their work uncovering a giant, and largely unpublicized, Canadian oil spill. Since then, the magazine has continued to publish hard-hitting journalism on a range of climate-related topics. Coverage of Exxon's own research into global warming in the 1970s - and its subsequent public campaign to discredit and block further investigation - is a case in point. In this multi-part series, published in late September of 2015, InsideClimate News reporters examine primary sources, including internal company files, to expose Exxon's outright war on the science of global warming. Readers may also scout the site by eight other categories, including All Stories, Carbon Copy, Tar Sands, Clean Economy, Today's Climate, Gas Drilling, ICN Books, and Big Oil, Bad Air.
