Still waiting for an actual scientific analysis of how a gas that comprises 0.4% [...] causes climate change.

You are off by an order of magnitude: The concentration of CO₂ in the atmosphere is roughly 400 ppm.

That is 0.04%.

The water vapor present (in varying concentrations) in the atmosphere has a greater greenhouse effect. So the logical thing to do would be to cover the world's oceans in plastic sheeting, to prevent evaporation!

The climate cult would tell you that covering only the lakes in the USA would change everything.

Because, you know, virtue signalling. ;)

Plants can never seem to grow as much as they are designed to grow due to the low supply of CO2.
