The ads included calling climate change a hoax and were paid for by conservative US groups
Adverts on Facebook denying the reality of the climate crisis or the need for action were viewed by at least 8 million people in the US in the first half of 2020, a thinktank has found.
The 51 climate disinformation ads identified included ones stating that climate change is a hoax and that fossil fuels are not an existential threat. The ads were paid for by conservative groups whose sources of funding are opaque, according to a report by InfluenceMap.
