@K_Reuss_Manaus I don't think the intended meaning here is that palaeo research isn't important or impactful (quite the opposite), just that it can usually afford to wait 6 months for peer review.
Maybe that's my fault - when the authors say "not urgent" it's in comparison to research on COVID-19 in the first months of the pandemic, but I had to cut that out to fit the quote within 500 characters.
