The ‘Historical Jigsaw of Climate Deception’: Private Notes Show How Big Oil Spread Climate Science Denial: DESMOG

EXXON & climate change

We’ve all heard the dodgy arguments: ‘the science is uncertain’, ‘climate change is natural, not down to humans’, ‘science has been hijacked by politics’… Now a new cache of documents sheds light on the origins of the disinformation.  

In another verse of a now familiar refrain, a fossil fuel industry group in the 1990s publicly promoted arguments to undermine confidence in climate science while internally acknowledging their products were driving up temperatures.  

• How Big Oil Tried to Capture the UN Intergovernmental Panel on Climate Change
• Global Climate Coalition: Documents Reveal How Secretive Fossil Fuel Lobby Group Manipulated UN Climate Programs

A cache of meeting minutes, briefings, and emails uncovered by the Climate Investigations Center shows how industry group the Global Climate Coalition (GCC) used its financial clout and political connections to cast doubt on mainstream climate science until its disbandment in 2002. The GCC would for decades cast doubt on the veracity of climate science and strategically spread the message that the UN Intergovernmental Panel on Climate Change (IPCC) was a politicised body, to discourage regulatory reform that would hit coalition members’ profits. 


The documents show that the group, which counted fossil fuel giants Exxon, Shell, and Peabody among its members, knowingly pushed misinformation on climate change even as the GCC internally acknowledged humans’ impact on the climate “cannot be denied”. Some of those same companies have been the recent targets of lawsuits seeking damages for climate change impacts.
