Not established. In most cases CO2 clearly leads temperature. In one place,
it *seems* to lag, but then the data has too much error to be definititve.
What IS defined, within the error bars, is the simple CO2/temparature coorelationship.

It is called the 'hockey stick graph' only due to similarity of symbology.
The fact that ther is a long stable period ( the shaft ) folloiwed by a
drastic and rapid rise ( the blade ) does NOT make for an argument either
for or against the facts.

Really. In reality it led to a check of the analysis which found an error in
the timeline related to O18/016 depostion rates that changed the lag to a
small fraction of the error bars. You really have to include the QUALITY of
the data when trying to reach firm conclusiosn.

Keep spinning Steve. Eventually, you may bore a hole to China.
