In the US, climate change misinformation is a large-scale effort powered by a network of influential philanthropists. This study uses NLP and takes a network approach to climate change denial, rather than focusing on individual actors. From the abstract: "Two of the most consequential developments affecting US politics are (1) the growing influence of private philanthropy, and (2) the large-scale production and diffusion of misinformation. Despite their importance, the links between these two trends have not been scientifically examined. The study finds that over a twenty year period, networks of actors promulgating scientific misinformation about climate change were increasingly integrated into the institution of US philanthropy. The degree of integration is predicted by funding ties to prominent corporate donors. These findings reveal new knowledge about largescale efforts to distort public understanding of science and sow polarization."
