Only Roger can spin an article that essentially throws cold water onto
the Anthropogenic Global Warming hypothesis into one that supports it.
I suppose Roger wants us to believe the putative "30%" man-made gg
component is responsible for the increased water vapour, but in fact
the increase could be due to rising temperatures that have nothing to
do with manmade GG. Notwithstanding what a FORTRAN 77 computer
simulation shows.

"Further research is needed on the AGW hypothesis".
