Volcanoes eject a very large amount of C02, a green house gas, when they erupt.

Not compared to human emissions. I addressed this claim previously.

Plus, the ash clouds only block sunlight from hitting the surface, the sunlight still enters the earth, and most of it stays there due to the greenhouse effect.

The atmosphere absorbs only weakly in the solar spectrum, something like 1% of the total solar flux. The surface, on the other hand, absorbs something like 70%-90% of all solar radiation reaching it (snow and ice cover can reduce this significantly). Very little of the sunlight reflected back to space by volcanic ash and aerosols is trapped on the way out. The cooling effect of reduced surface solar heating greatly overpowers the weak warming of increased atmospheric solar absorption.

I don't have a clue if volcanoes eject enough CO2 to cause any sort of long term warming, but they most assuredly don't cause any sort of long term cooling.

Volcanoes can only cause planetary warming via GHG emissions on time scales of millions of years. The volcanic GHG flux is not nearly large enough to cause warming on timescales of centuries to millennia.

He'll be the most famous scientist alive if he disproves man-made global warming.
