[7][8] In April 2009, despite having no formal education in the field of climate science,[9] Morano founded and became executive editor of ClimateDepot.com, a website sponsored by the Committee for a Constructive Tomorrow (CFACT).
[10] In January 2013, Morano debated Michael Brune, executive director of the Sierra Club, again on Piers Morgan Tonight.
[12] In 2019, Morano's blog described 16-year old climate change activist Greta Thunberg as an "autistic prophet", and he retweeted criticisms of her that center on her autism.
While some climatologists who felt they had been bullied were reluctant to give their names, Michael E. Mann openly said that Morano "spreads malicious lies about scientists, paints us as enemies of the people, then uses language that makes it sound like we should be subject to death threats, harmed or killed."
In March 2012, Morano posted an article and the email address of sociology professor Kari Norgaard, who had presented a paper on why it is difficult for societies to take action to respond to climate change.
[16] Morano says that emails targeting climate scientists can be nasty in tone, but he defends the practice of posting their addresses by noting that he, too, has received hate mail.
