One example (there were more) of CO₂ output sufficient to change atmospheric composition was the "K/T Boundary Extinction" (end of Cretaceous), when giant worldwide fires caused by the Mexican Chicxulub bolide (meteor) impact incinerated most of the world's forests (the sky rained molten, red-hot glass all around the world), and acoustic convergence and constructive interference caused giant earthquakes on the opposite side of the world underneath India, cracking the Indian continental crust and allowing a flow of basalt lava at the surface in a many-miles-wide fracture zone hundreds of miles long, that vomited volcanic gases into the atmosphere and flowed molten basalt thicks several thousand feet thick over a period of about 10,000,000 years. THAT is what it takes to do the kinds of things the AGW alarmists are woofing about.

it’s just too bad we don’t have ANY republicans with spine enough to stand on a platform and state these things so that the public is not ignorant of the facts- Your scenario, along with showing how little CO2 there actually is I n the atmosphere AND showing that CO2 ALWAYS follows temperature rises some 800 years AFTER the temps rise- should be enough to get anyone with even a modicum of common sense to realize that there is simply no way the piddly amount of CO2 in our atmosphere can be causing global climate change- none!- Again- Scientists should be ashamed of themselves for even suggesting it is!
