Hi Scott,

I agree that differences of opinion are to be welcomed on Tweeters.
However, I don't think it is ideological dogmatism to accept that global
warming is mainly a result of human activity; while some organizations still
hold non-commital positions, there is no scientific body of national or
international repute that currently maintains a dissenting opinion. You
might want to compare:
http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_change vs.
http://en.wikipedia.org/wiki/List_of_scientists_opposing_the_mainstream_scie
ntific_assessment_of_global_warming)

Not that I trust Wikipedia in all matters, but the lists can use it as a
starting point for further exploration.
