I opened the "Summary for Policymakers" listed right on their home page, and it popped up a PDF titled "AR5_SYR_FINAL_SPM-1.pdf". That's where I searched on the word "vapor" and found only one occurrence -- inside the word "evaporation".

I guess the "for the Physical Science Basis" report is something different that I haven't found yet.

Holy cow do they make it hard. I had JavaScript off, which made their page much more usable. Either do that or ...

With JavaScript on, apparantly the UX concept is 'Easter eggs': There are 4 images arranged horizontally at the top. If you click image, one the section beneath it changes. The second image is "Physical Science Basis".

All that work making the reports accessible, hamstrung by web design.
