Oh boy. A right of center global warming denying source pointed out what we already knew. Nobody said anyone found infected animals at the market. There were infectable animals sold. The available data tells us most of the first people who got Covid had contact with the market. It may be potentially imperfect, but it is the only data we have. I imagine there is more to it than the smug dismissal of the Spectator.
There is also the molecular clock analysis. This too points away from the lab leak theory.
Nobody has ever said the lab leak theory was disproven. There is just a difference between possible and plausible. The right wing, especially the science denying right, likes a narrative in which China and scientists caused the pandemic and covered it up. So they cling to any shred of evidence, no matter how flimsy, that supports the narrative.
The author, Matt Ridley, thinks Global warming is beneficial.
