Yes, man has an effect, but it is becoming more obvious that his effect is smaller than many believe.
We have to ask ourselves a few questions:
1. What can be done?
2. How effective will our actions be?
3. Will we sacrifice lives, jobs, and economic development for a tiny incremental change?
4. Will the development of alternate fuels, possibly fusion, over the next 100 years make this problem unimportant?
5. What if these are primarily natural cycles? Do you really think we can do anything to stop them?
As far as your presumption about the amount of CO2 in the atmosphere, well that has varied considerably more than the present number over time and we are still here. It is rather pointless to argue that a small change will destroy life on earth.
Lastly, unless you plan to dry your soy crop on an empty Interstate, I don't think there can be much that man can do. Of course he could do a lot of very costly things, like stop burning fossil fuels. Then a lot of people would start strarving and freezing to death.
Finally, the Document presented in Paris is grossly flawed. Can you recall a time in history in which the UN was considered a fount of scientific or political advice worth even considering as valid?
