- "That means that if you put water there, it can stay there for a lot longer"
There's more to it than that. Large parts of the water bands in the troposphere are already saturated: adding more and more of the same absorbing material doesn't have a linear effect, but diminishing returns. But the stratosphere is completely dry. The marginal effect of a water unit is a lot greater.
