Radiation caused skin cancer isn't the only or even the main concern. Skin
cancer was the selling point used by environmentalists to get the attention
of the public to drive political action to conserve ozone.
>From "Scientific Assessment of Ozone Depletion: 2010": "An important
remaining scientific challenge is to project future ozone abundances based
on an understanding of the complex linkages between ozone and climate
change"
Eg. Joellen Russel had/has a theory that Antarctic ozone loss coupled with
heating in the tropics has increased in the temperature gradient between
the two regions, increasing the power and position of the Southern
Westerlies thus driving a stronger Antarctic Circumpolar Current which
affects/will affect gas and heat exchange at the ocean surface with global
effect.
And then there is the history, where modelling that indicated not much
should be happening caused NASA to not see the ozone hole, for years, as it
developed because the unheard of until then low readings were discarded
from analysis because an assumption was built in dismissing any reading
that low as instrument error, dictates caution in this area. NASA looking
down from satellite couldn't "see" the ozone loss until Farman on the
ground looking up reported it. Further delay resulted because Farman took
years to get up the gumption to report because he knew NASA was looking
down above him and was not reporting.
