Climate scientists know about volcanoes, which ones have erupted and when. Volcanoes and asteroids can and have caused such climate changes. Fact still remains the largest climate simulation program utilizing supercomputers factoring in every know related effect predicts the amount of CO2 caused by humanity is the main cause of Global Warming.
I think what you meant to say is that volcanoes have in the past erupted to produce more CO2 than humanity ***for a given duration***. Oddly enough you're missing a huge factor, "Duration." IOW, humanity continues to pump out a steady amount of CO2 year after year.
