I cringe every time I hear Al Gore refer to the "consensus of the worlds' top scientists". As others have noted, 'consensus' is more about politics than science. Science is about our best attempt at not fooling our selves in all the usual human ways.
The problem we have with our current concerns about CO2 emissions and possible catastrophes, is very much like our concerns with Saddams nuclear capabilities. We can't know enough to prove anything for certain. And, we don't want to err on the wrong side of a potentially catastrophic unknown.
So, while a 'consensus of scientists', about something that cannot be proved, should be an oxymoron, it may be the best we humans can do when confronted with a potentially dangerous unknown.
I think Al Gores' strongest arguement - that I whole heartedly agree with - is that we need to be doing these things for other reasons anyway.
