How do you win a battle, if you’re fighting in the wrong arena? A look at how the virtues of science were being used against the scientists. Uncertainty is an inherent part of climate change science, but the word means something different to scientists. This is the lowdown on how scientists are literally using a different language to us and why this has played into the hands of those who want to delay action on climate change. From climate change to smoking and cancer, this is the story of how doubt has been manufactured. This 10 part series explores how powerful interests and sharp PR managers engineered doubt about the connection between smoking and cancer and how similar tactics were later used by some to make us doubt climate change. With the help of once-secret internal memos, we take you behind boardroom doors where such strategies were drawn up and explore how the narrative changed on one of the most important stories of our time - and how the marketing of doubt has undermined our willingness to believe almost everything.
