A carbon dioxide increase will raise the altitude of clouds and they will begin to trap more heat than they reflect.
Then there's around 10-different greenhouse gases trapping more.
The increased global warming will raise the water vapor content of the atmosphere, which is the largest GHG we have ( until surpassed by methane ).
I failed to find any 'band-pass' where long wave could squeak by.
Did those frequencies you mentioned qualify with all GHGs?
