Are you ready to pick one yet? Does exhaling CO2 cause climate change such as warming the planet, yes or no? Why can't you answer the question? Are you to embarrassed for your grant seeking friends? Or are you being paid from grant money for saying CO2 is a poison?
I won't be picking either of your choices. Try not to take it personally. It's just a sucky strategy on your part.
CO2 warms the planet. The physics doesn't care where it comes from. Human's, worldwide, exhale just under 3 billion tons of CO2 annually. Fossil fuel combustion produces a little over 35 billion tons annually. Besides the fact that human exhalation represents only ~8.5% of fossil fuel's contribution, the CO2 humans exhale gets almost immediately consumed. Plants worldwide absorb roughly 100 billion tons of CO2 annually. Unfortunately, well more than half that absorbed CO2 gets released when the plant material decomposes. What it boils down to is that within much less than an order of magnitude, the amount of CO2 released by human breathing is absorbed by plant respiration. Both processes are continuous so the net effect is very close to nil.
The combustion of fossil fuels, however, have a very different story. Fossil fuels come from plants that died and were buries tens to hundreds of million years ago. Releasing that long-sequestered CO2 has a real impact on the level of CO2 in the atmosphere. It is by far the largest contributor to the long rising Keeling curve.
So, I hope that's enough quantitative information that you might give some serious thought to dropping your nonsense about human respiration and global warming.
Note anthropogenic is an adjective which means originating in human activity, yes? Or are you and your friends using a different definition?
I'm quite certain that the experts are using the term correctly. I am growing less certain that you are doing so, but we shall see.
For example, exhaling CO2, aka. breathing, is a human activity, correct?
Yes, human breathing is a human activity. (shakes head sadly)
Or are you and your friends picking and choosing which types of human activities are sinful with regard to CO2 and which C02 activities will be deemed ok by your so called esteemed colleagues.
I am not a scientist. I am a systems engineer at an R&D facility operated for the US Navy. I have working relationships with a number of scientists, but the topics concern sensor and weapon systems. Since neither I nor any of the scientists with whom I work, do climate research, I have no collegial relationships with climate scientists, esteemed or not. In general, I accept the views of mainstream science on all science topics; they are my views because I adopt them
As another example, cow farts. How many cows do you want to kill in the fields to save the planet from cow flatulence?
How much should we be forced to pay for each breath, burp, or cow fart taken in vain against the planet?
Nothing.
What is your per human budget for anthropogenic CO2 generation? How much do your so called scientists want each human to pay for their so called CO2 budget?
Go here and read. The topic is orders of magnitude more complicated than this puerile question indicates you believe.

What material did I point to that you are saying is stupid? The picture about the respiratory cycle that shows how plants use CO2? You think photosynthesis is stupid? You think I'm lying about photosynthesis? ROFL put down the crack pipe.
I don't have a crack pipe to put down. What would really help, though, would be if you had a basic science textbook to pick up.
