Exxon Mobil is under investigation by New York Attorney General Eric Schneiderman for allegedly misleading the public about the risk of climate change.
The investigation comes after the Union of Concerned Scientists revealed over the summer Exxon Mobil had been researching the risks of climate change as early as 1981.
It also claims Exxon Mobil had been funding campaigns undermining climate science, while it's own scientists warned executives of the dangers of climate change.

Some see this as a chance to open up new lines of attack for climate change litigation. More attorneys general could join the investigation.
And The New York Times reports "people with knowledge of the case" have said the inquiry might expand to other oil companies. At this time, however, none have received subpoenas.
