Rather than spending my time trying to get people to the point I'm trying to make, I figure it would be easier just to get to the point.
There are only a few things that any one person has to believe are possible to believe that man-made climate change is possible. Not saying it's definitely true, just possible.
Regarding #2: It's estimated that, without an atmosphere, the lowest temperatures on Earth would be negative ~ -350° f and the high temperatures would reach up to ~250° f. This is the case because the atmosphere blocks some of the Sun's energy from reaching the earth, keeping days coooler, and, slows the loss of energy into space at night, keeping nights warmer. You can experience something similar on cloudy nights. Cloudy nights tend to remain warmer because clouds act as a barrier, not allowing the energy radiating from the Earth to escape into space. The clouds actually absorb the energy and emit it towards the Earth's surface.
Regarding #3: assuming that #2 is correct, then it stands to reason that a change in the composition of the Earth's atmosphere would would impact temperatures in the same way a cloudy night impacts temperatures. If the atmosphere became more efficient at preventing energy from escaping the surface of the Earth, that is really all that would be needed to see an increase in temperatures and/or climate.
Regarding #4: This is the part that is unknown. The Earth's ecosystem is so complex, with so many "moving parts", that it can't be known for certain that the atmosphere can change, and can change enough, to truly impact climate. But, this isn't a question of what is known. This is a question of whether or not it's reasonable to believe that climate change is possible.
Basically, if you believe that the atmosphere can change and more effectively slow the rate of energy escaping onto space, specifically based on the actions of man, then you are acknowledging that climate change is possible.

- Energy from the Sun increases temperature on Earth. When energy (generally referred to as "heat" in everyday conversation) leaves the Earth, the temperature decrease.
- The Earth's atmosphere impacts energy coming from the Sun and energy leaving the Earth's surface and, therefore, also impacts temperatures.
- A change in the structure/contents of the atmosphere would impact #2.
- The structure/contents of the atmosphere can change and can change and change enough to impact temperatures and, therefore impact climate.
