Pope Francis can claim many firsts; he is the first non-European Pope since 741 AD, the first from the Americas and the first from the Southern Hemisphere. Given his nuanced positions on science issues like climate change and agriculture, some might also consider him the first scientific Pope. That isn't correct, but he may be the most scientific in history.
Francis is not scientific due to credentialism, he does not have any advanced degree in chemistry. Instead, he is scientific by behavior.
