No, it is quite simple - surely even enough for you !
There are 2 main effects in action, according to the prevailing theories. The first is MMGW, caused by generating large quantities of CO2, methane, & water vapour, which act as greenhouse gases and cause temperature rises experienced at surface levels of the planet. The second is the effect of particulate pollution, ( which is also a side effect of burning fossil fuels ), which when it reaches critical higher levels acts to reflect solar radiation, and therefore cools the planetary ecosystem. The second acts to reduce the effect of the first.
At lower levels, particularly during take-off, climbing to cruising altitudes, and landing, aircraft are contributing to the greenhouse effect, once at heights above 30,000 feet they are predominantly adding to GD.
