Notice that you keep avoiding his question:
"Here's a math exercise for you ... it's typically reported that man-kind releases 40 gigatons of CO2 every year ... how much is this in atmospheric ppm? ... this value is observed as ≈ 2.5 ppm(volume)/yr at the Hawai'i gauge ... and don't forget density differences ..."
Waiting waiting.....
Why would the number make a difference?
I'm asking because some people always focus on "small numbers" as if small numbers can't have a HUGE effect.
So I'm going to have to ask WHAT WOULD YOU DO WITH THE NUMBER?
But more importantly: NATURAL SOURCES OF CO2 are presumably in balance with the natural world and the carbon cycle. The key is that humanity is release a large amount of previously sequestered carbon at rates in excess of the natural cyclings.
The natural cycle of carbon has releases from a variety of natural sources. Humanity has taken a huge chunk of carbon that was "sequestered outside of the carbon cycle" for millions of years and is now pumping it into the atmosphere.
Like others have noted: the atmosphere has, before humans showed up, had a variety of different levels of CO2. Sometimes MUCH higher than today. The key then becomes what does OUR influx of carbon mean?
Well it clearly means we are looking at measurable warming due directly to our actions. Sure it's been hotter in earth's past. The problem is that our societies didn't exist then and now we are in the process of RAPIDLY changing the climate and endangering out ability to deal with outcome!
