What does this translate into in terms of Ford F150s?
Roughly 4 150s.
I would guess , you would need at least a couple of million of them.
You’ll have to think in terms of a diesel engine (or at least the older ones). The soot emitted (cooling effect) overwhelms any warming effects the CO2 may have.
No, Dr Glikson ( More on Carbon Induced Global Warming )

Harmful carbon?
Glikson also tries to suggest that carbon is only beneficial for plants in glasshouses where humidity is high. Awkwardly for him, field studies from fifty years ago show that atmospheric carbon dioxide is the rate-limiting factor for plants meaning they use up all the CO2 they can between sunrise and 12 noon each day, then slow down until the carbon levels are restored in the air overnight.[iii] One of the main purposes for water molecules in plant tissue is to be exchanged for CO2 (known as evapotranspiration), so not surprisingly not only do plants prefer higher CO2 they grow faster they also cope better with drier conditions. Overall, hundreds of studies show that plants typically grow 20-50% more biomass with higher CO2 levels.[iv]
