Sorry, I didn't figure out how to find the author's email yesterday for
this article. The way to do it is to go to the Science website (
www.sciencemag.org) then click on the current issue. Then find the
article, and click on "abstract" which is open-access. There you see all
the authors, and it gives the corresponding author (Line K. Bay)'s email:

Hope from the Pope
Will Pope Francis's climate message break through where others have failed?
