The New York attorney general has begun an investigation of Exxon Mobil to determine whether the company lied to the public about the risks of climate change or to investors about how such risks might hurt the oil business. The investigation focuses on whether statements the company made to investors about climate risks as recently as this year were consistent with the companys own long-running scientific research. The people said the inquiry would include a period of at least a decade during which Exxon Mobil funded outside groups that sought to undermine climate science, even as its in-house scientists were outlining the potential consequences and uncertainties to company executives. In a separate inquiry, Peabody Energy, the nations largest coal producer, [has] been under investigation by the attorney general for two years over whether it properly disclosed financial risks related to climate change. Some experts see the potential for a legal assault on fossil fuel companies similar to the lawsuits against tobacco companies [that] were found guilty of a massive 50-year scheme to defraud the public. Inside Climate News and The Los Angeles Times have reported that Exxon Mobil was well aware of the risks of climate change from its own scientific research, and used that research in its long-term planning for activities like drilling in the Arctic, even as it funded groups from the 1990s to the mid-2000s that denied serious climate risks.
