Last month a study <https://www.pnas.org/content/116/8/3006.abstract>  in
Proceedings of the National Academy of Sciences did attempt a kind of
virtual time-travel, using digitized museum records of milkweed and monarch
specimens dating back to 1900 to assess population trends. The analysis
indicated milkweed and monarchs both started declining in the 1950s-well
before the advent of glyphosate. Flush with this correlation, the authors
declared that blaming monarch loss on practices involving herbicide-tolerant
crops was "neither parsimonious nor well supported by data." (Parsimony is
what scientists call the simplest explanation that fits with observed
evidence.)
