I don't know what to think about this.
On the one hand, the deniers/sceptics include so many loonies that the safe bet seems to be the other side.
But on the other hand, I do find the data massaged too much to fit a predetermined conclusion.
Perhaps the safe position is to say that it is getting warmer, that it might be caused by humans but could also be caused by lots of other factors, and that what we can do to change the climate won't be enough anyway.
