Are Climate-Change Sceptics or the Proponents gambling on our future, given fossil fuels will run out anyway?

It has nothing to with better safe than sorry. It case you hadn't noticed, the economy stinks. Forcing businesses and individuals to make expensive changes right now would finish off what's left of our pathetic economy. So yeah, we better be damn sure this crap is man made before we destroy ourselves trying to save ourselves. Climategate casts doubt on all that. personally I think it is a natural process. The proof must be irrefutable and it is not.
