I'm glad I'm not one of those, then...But, neither do I discount something just out of ideological prejudice...There are indeed many variables that we do not yet fully understand (hence all the ongoing research?) but, IMO, the only way to deny the reality of AGW (per se) is by claiming that anthropogenic CO2 is somehow not a greenhouse gas...And, the ice-melt this year has exceeded expectations, after all? How do the 'sceptics' explain that?
