Indeed not. I have spent a good deal of time examining such objections, and
have not found any that are destructive to the case made in IPCC 4AR.

The fact that the CO2 PPMV does not coincide with the known
production added is a clue that the case is not closed.

The fact that CO2 exists in such a small proportion to the
real greenhouse gas water vapor is a big clue.

The fact that the mass of all the CO2 in the atmosphere is
not enough to capture the amount of thermal energy involved is a bigger
clue.

The fact that evaporation cools many times more than any
possible IR radiation from the atmosphere.

The fact that clouds block incoming radiation causes any
energy budget accounting to be inadequate for the task.

And the fact that some near all time record lows for the
month of July are occurring suggests there is a move toward a cooling
trend.
