The author doesn't know what he's talking about. Let's look at this particular passage: The author of that article doesn't understand the R value of viruses and how those varying numbers affect spread. COVID has an R value that is 2-5 times higher than flu. Of course he's an environmental science PhD whose research in ecology/climate change/hydrology has almost no relevance to viral spread. He needs to stay in his lane. I don't pretend to know anything about the science of hydrology so I'll stay out of his realm of expertise.
