A new report finds that dozens of climate disinformation ads have run on Facebook in the first half of 2020.
Produced by a variety of conservative groups, ads have received a total of 8 million views.
The report, produced by the climate group InfluenceMap, accuses climate-denialist groups of using Facebook's advertising platform to spread disinformation, 'intentionally seeding doubt and confusion around the science of climate change.'
The ads were predominantly targeted at men, people in rural states and Americans over the age of 55.
Most raised doubts about the science of climate change, including denying there's consensus or certainty about it, and attacked the credibility of climate experts.

A report from InfluenceMap indicates more than 50 climate misinformation ads ran on Facebook in the first half of 2020
Launched by Dylan Tanner on the eve of the Paris climate accords in 2015, InfluenceMap analyzes how corporations influence climate change opinion and policy.
Its newest report, 'Climate Change and Digital Advertising: Climate Science Disinformation in Facebook Advertising' found 51 climate-denial ads running on Facebook between January and June 2020.
The spots cost a total of $42,000 to run and received a total of 8 million impressions, though it's not clear how many people saw them in total.
InfluenceMap says that while the ads were produced by a variety of right-wing groups - such as Prager University, Turning Point USA, and the Mackinac Center for Public Policy - the ultimate source of funding 'is often opaque.'

Prager University, for example, received early funding from Dan and Farris Wilks, who became billionaires in the fracking industry.
To date, only one ad was removed by Facebook before it was scheduled to end.
The group lists several strategies the ads use to 'sow doubt and confusion' around the science of climate change, including denying there's consensus or certainty on climate change.
The most common approach 'is to attack the credibility of climate science and climate science communicators,' like the UN's Intergovernmental Panel on Climate Change.

InfluenceMap's research also suggests that the advertisers micro-targeting their messaging to specific audiences.
In ads shown predominantly to 18-34 year-olds, the videos mostly focused on contesting the future consequences of climate change.
In those shown to people 55 and up, though, the focus was on debating the causes of climate change.
One ad from Prager University featured Alex Epstein, author of The Moral Case for Fossil Fuels, slamming the Green New Deal and disputing the environmental consequences to increasing greenhouse gases.
'Such predictions have a decades long tradition of getting it wrong,' Epstein says. 'Fossil fuels are not an existential threat … The Green New Deal is an existential threat.'
Craig Strazzeri, chief marketing officer at PragerU, denied the company was running disinformation ads.
'Apparently 'disinformation' means anything Facebook or the left disagrees with,' he told The Guardian. 'The ad in question is an educational video on the truth about the Green New Deal.'
