I made some factual statements about how Man believes he controls the weather (usually through prayer and ritual), and that this has been going on since the first human believed in God, or Gods. It is a very common and familiar human activity. Do you dispute that?
Allen,
you seem to be running a 'we are insignificant' argument to prove or suggest that insignificant mankind couldn't possibly affect the weather on the huge plant Earth.
The analogyYou (or your friend) has already provided a calculation of the approximate ratio of the size of humans to the size of the planet and made reference to the size of bacteria.
You seemed to be offended when I referred to this as an 'analogy' - so I take it that not only are we not on the same page, we are not using the same dictionary.
Firstly, I see two issues with your analogy (sorry to use that word), firstly shouldn't you be comparing the size of a human to the size of the atmosphere around Earth (not the entire planet)? And secondly, as I've stated before, it is not the size of humans that counts, but rather the size of their CO2 production.
Also, the analogy (there's that word again) maybe a little deceiving in another way as the present percentage (volume) of CO2 is quite low (380ppm) so, just maybe, it won't take that much extra CO2 to make a notable difference to the CO2 concentration.
The factsAnyway, that's enough on debasing your analogy (Oops, that word!), let's look at the
facts and see how things stack up.
- CO2 levels have increased from 280ppm to 380ppm in recent times (do you dispute that?).
- The extra CO2 has shown to be almost entirely made from burning fossil fuels - man-made (do you dispute that?)
Therefore your argument that insignificant mankind couldn't make any impact on the huge earth? is false.
Your analogy is a poor one as it does not accord with observed behaviour (CO2 has actually increased due to human activity), or help explain the behaviour (poor model). It uses a wrong size/volume as a base in any case. (i.e. it is using the size of the whole earth rather than just the size of the relatively thin atmosphere).
If you want to peruse this line of argument you will then need to move to the question of whether a seemly small percentage of CO2 in the atmosphere can change the climate.
