It may be a fallacy in the strict logical sense, but correlation, or in
the wider sense, statistical significance is the basis of most research
in the natural sciences for confirming the hypothesis.

In fact looking at that graph there really isn't much evidence for your
statement. On the contrary, at 32,000 BP you can see CO2 preceding the
temperature rise. You should also consider that recent work has shown
that the processes of glaciation and deglaciation took place at slightly
different times in the northern and southern hemispheres, meaning that
any statements based purely on the antarctic ice cores are of
questionable value. For example take a look at Shakun et al "Global
warming preceded by increasing carbon dioxide concentrations during the
last deglaciation", Nature 2012.
Incidentally, has it occurred to you that if "correlation proves
causation" is a fallacy, then your the argument that "temps precede CO2"
is fallacious? It's ironic that you should make both assertions in the
same posting.
