Sheldon's formulation is fine, provided he can locate a source for the
"overwhelming majority" part and gives a numerical definition for
"overwhelming majority".
As it stands now, the only survey mentioned at Wikipedia seems to show
much less than "overwhelming" support for the GW theory. Perhaps it
depends on how one interprets the survey results?
But really, on such a crucial issue as Global Warming theory, with tens
or 100s of billions of dollars at stake (not to mention human lives,
assuming the theory is actually true!) -- I'd rather have more than an
average of answers from a survey question. Better to dig up exactly how
many answered "strongly agree", "somewhat agree", etc.
If there's really a consensus, showing the survey results this way will
make it obvious. Surely such a capable researcher as Mr. Rampton has
these figures at his fingertips already.
