The AGW hypothesis says Carbon Dioxide, CO2 (the stuff coming out of my old SAAB) prevent heat escaping out of the atmosphere which, in turn, leads to a warmer planet.
There are 2,500 air molecules around each CO2 molecule in the atmosphere.
Let’s imagine that every molecule is the same as 1 meter in this thought experiment. 2500 meter + 1 meter (CO2).
Let’s say this is the width of a dam spillway, 2501 meters, where excess water flows out when being overflowed by heavy rainfall or by spring floods, naturally designed to protect the dam from damages.
Also imagine you can close or block the spillway, one individual meter, or locks at the time, in any order you wish. I.e any locks, but only 1 of the 2501 locks.
If 2500 locks / meter (2,5 km.!!) are open and one gate, 1 meter, or one locks, is closed ..
What effect will the one lock being closed have on the total amount of water that passes over the spillway have? Will the water be contained and potentially lead to severe damage on the dam or further upstream?
Will the water just continue, bypassing the 1 meter wide blockage? Will it be possible to measure the increased flow in the other 2500 open locks? Surely you can calculate the increased flow using math ..
.. but will it be possible to measure? (What about the inflow to the reservoir, is it constant? What other consumers (sinks) are there?)
Will it help if the locks is a “super-locks” with amplifying powers?
That’s not all, imagine you had 400 dams just like the one above, right!? Ca. 400 CO2 molecules are in the atmosphere today. 1 CO2 molecules for every 2500 other air molecules.
The bizarre part is, of those 400 CO2 molecules in the air today, only ca. 15 CO2 molecules comes from burning of fossil fuels (less than 5%).
That would mean, of the 400 dams each with its own CO2 locks, humans only account for 15. On top of that, the 15 locks will not only ruin those 15 individual dams, it will also wreck the other 385.
Another way to illustrate it: There are 2,500 air molecules around each CO2 molecule, because the total amount of CO2 in the air is 400 parts per million. Therefore, each CO2 molecule must be 2,500°C to heat the air 1°C—an impossibility.
