This is only half tongue-in-cheek.
With the ambient noise going up, and there being limits to the size and cost
of receiving arrays most amateurs can build, the next logical step is to
raise the output power. Perhaps the FCC should be petitioned to raise the
legal limit? They were supposed to safeguard our frequencies against
interference (man-made noise included), but since they have failed to do
that, they should allow more power to restore the original signal to noise
ratio? (Which some already do, anyway.)

The document was published last year so we might assume the noise graph is
up to date. To put this in perspective,
To put the ITU-R P.372-14 claimed noise in perspective here's the
calculated antenna terminal voltage for a 100% efficient 1/4 wavelength
vertical in 500 Hz bandwidth. S-units are also shown.
Quiet receiving site -- 4.7 nV/m, vert 1.3 uV, S-4
Median city noise -- 66 nV/m, vert 19 uV, S-8
