Additional Information

DeSmog's About page states [retrieved 2/23/23]:

Now a global organization, with reporters and researchers spanning North America, Europe, Africa, and beyond, the DeSmog team works to expose corporate misinformation from major fossil fuel interests, including the likes of ExxonMobil, Koch Industries, and others with a documented history of undermining climate science and action. We conduct original research and reporting on a range of issues in the broader energy policy dialogue. In many cases, we find the same tactics, and many of the same people, that DeSmog first began exposing in our early research into the climate denial industry, are now sitting alongside a new breed of lobbyist, downplaying potential solutions to climate change, and promoting questionable “silver-bullet” solutions.
