Note that 1% of the earth's surface is a metric s***load.

But yea the white painted surface is actually cooler than the air around it is correct (weather dependent though, doesn't work if the sky isn't clear). The high emissivity is one reason why white is cooler than even a very reflective silver. The silver just reflects most of the heat, while the white actively radiates if its temperature is higher than the surroundings.

No more absurd than the resultant, not reducing the rate of increase but rolling back global heating to date.

I understood that CO2 and water vapor are transparent at the target frequencies.

It wouldn't matter if that were 100% fact.
The 'actual' energy balance must take into account, the presence of all the other tropospheric greenhouse gases which are NOT transparent to those frequencies.
