Climate policy: The scientific consensus on ongoing anthropogenic climate change leaves no room for reasonable doubt (Cook et al. 2016; Powell 2019). Science denial has considerably delayed climate action, and it is still one of the major factors that impede efficient measures to reduce climate change (Oreskes and Conway 2010; Lewandowsky et al. 2019). Decision-makers and the public need to know how to distinguish between competent climate science and science-mimicking disinformation on the climate.
