Smoking -> global warming -> SARS (2019)

 Old cynics like me will not have been surprised by the revelations in the recent BBC Radio 4 series How they made us doubt everything. 

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.

Now the deniers have moved on, according to DeSmogUK:

The coronavirus crisis once again saw the UK divided — between those putting their trust in public health experts and their recommendations, and those quick to question the science on which the government claimed to base its decisions for controlling the pandemic. For those who have watched the decades-long efforts to slow climate action, this was a familiar phenomenon. And the coronavirus pandemic seemed to give fresh ammunition to some familiar faces.

A close look at commentary on both COVID-19 and climate change reveals significant crossover between unqualified voices casting doubt on experts recommending action.

Why?

“There’s nothing mysterious about this,” says Stephan Lewandowsky, a professor of cognitive science, who studies the persistence of misinformation in society at the University of Bristol.
“I think COVID is just climate change on steroids in a particle accelerator,” he says. “The same forces are happening: you have the inevitability of a virus which is the same as the inevitability of the physics. And opposing that you have politics which motivates some people to deny the inevitables and instead resort to bizarre claims.” 

The difference this time is that the doubters have no clear vested interest in pushing their anti-science. This may reduce the speed of spread of their propaganda because of the lack of corporate funding, but on the other hand could lend a spurious air of authenticity to their doubts.
