Its a balanced thermal system, but its hardly finely balanced.
Just look at some of the variations we have had in the past.

What you can also see is that its actually quite well buffered too as
changes normally take a few decades.


The variations in the past have been significant. That is the point you
seem to be missing is that they may not have been caused by anything
significant.

Well we know that some of the warm periods were not produced by more co2.
We also know there was more co2 during some of the cooler times.

So what insignificant thing were you thinking might be causing the
warming that may be happening now?

I have already said that I sit on the fence regarding climate change.

I was just trying to undo some of TNP false assertions.


A small increase in volcanic activity can have a profound effect on
global temperatures and a small change of precipitation in the Atlantic
can have a significant effect on the Atlantic Conveyor causing a massive
change in the weather patterns in the Northern hemisphere.


Weather is not climate as any GW expert will tell you (after a cold
spell).

Agreed - but we're splitting hairs.
