The appropriate rejoinder is often "Compared to what?" For example, "What if the application is not spatially uniform?" Uneven application results in uneven cooling, therefore pressure differences, therefore new winds are generated. Assuming spatially homogenous effects glosses over all that potential for redirecting winds and moisture delivery. But it would show up as increased variability atop what climate change is already providing--so the question is how much, compared to the variance we have inadvertently generated for the last sixty years.
