Wikileaks exposed it, from Podesta and Steyer:

Since the fivethirtyeight.com uproar, Pielke has quit publishing about climate change. He’s gone on to become a world-leading expert on sports and doping. He now heads the Sports Governance Center at the University of Colorado, which is housed within the university’s athletics department. He has more than 8,000 followers on Twitter and is an active, maybe rabid, tweeter. “I’m having a blast,” he told me. Working on climate change, he said, “you wake up, it’s the same people arguing about the same stuff. In sports, you have no idea what idea you will be writing about. . . . There’s so much going on. There’s so much upheaval.” What lessons did he learn from his stint in the climate-change discussion? He replied that the debate is “almost religious in its intensity.” Instead of having a rational discussion about the best ways to reduce carbon dioxide emissions, the debate has become solely “about power, about who gets to speak and whose voices are deemed legitimate.” The smear campaign against him by Romm and ThinkProgress was designed “to make public speech costly.”

The lawsuit against me and others is mentioned as well. What fascists these people are.
