Re: Heat balance
"I've always been puzzled"
There's been no debate because many feel that *any* debate as to the extent of overall warming from various sources will inevitably allow 'deniers' like me to pop up and argue that, although CO2 is a problem, it's a problem that we have time to deal with.
Of course there's some truth in that argument. Also, the fact that politicians won't do anything unless their feet are held to the fire doesn't exactly help matters when it comes to fair and balanced debate.
If there's a continued recovery in north pole ice over the next few years it's going to be an interesting time for nu-statistics.
