Abstract
Jan Rosenow’s review of Dieter Helm’s Climate Realism is titled ‘Realism needs today’s facts’. We classified its 44 factual claims against the sources it links. Five central claims, on temperature, electricity bills, the size of a future energy system, prices and the cost of solar power, are overstated or mislabelled. Each is corrected by a source the review links or by Rosenow’s own figures.
