He has not understood that a temperature rise initially pre-dating an increase in CO2 in the ice core record strengthens rather than weakens the standard theory.

Good grief! I can understand arguing that the green house theory might still be salvageable after such evidence...but to suggest it is strengthened by it? GET REAL!
It does seem like a rationalization assertion, but I can see how the science may support Monbiot. Perhaps the initial non-GHG warming could only account for so much, leaving the rest for GHG.
