Essentially unattenuated UV fluxes to the Earth would have been the case for
atmospheres with oxygen levels below about 0.002%, since no ozone screen
exists at these levels (Levine et al. 1980; Kasting 1987). There are serious
dangers for ...

How to Find a Habitable Planet
Earth, with its -percent O atmosphere, has a well-developed ozone screen,
and so the UV flux at its surface is relatively low. During the s and s
humans used a lot of chlorine-containing freons, which might have destroyed the
...

One always incurs a risk in extrapolating, but, as far as evidence goes, it appears
certain that during winter the atmosphere of regions a few degrees removed from
the North Pole also retains its ozone screen, so that observations of stellar ...

The importance of the ozone screen is readily apparent. Cicerone (1987) has
pointed out that a 10 percent decrease in atmospheric ozone, with a full
overhead sun, produces a 250 percent increase in UV penetration at 290 nm and
a 500 ...

If enough H-bombs are exploded, the ozone screen will be stripped away entirely
, and the world would be bathed with killing ultraviolet radiation. Freons entered
the picture by one of those improbabilities on which this whole story is built.

Handbook of Atmospheric Science: Principles and Applications
Lovelock (1988) has proposed that an atmospheric screen could have been
afforded by a hydrocarbon-particle smog, initiated by photolysis of CH4, well
before 2.5GyrBP, and far earlier than the ozone screen is generally thought to
have ...

Thus, the environments most favorable for the concentration and continued
growth of complex prebiotic molecules (proteins and nucleic acids) would be
subjected to UV-destruction in the absence of an effective oxygen/ ozone screen.

However, the uncertainty inherent in calculations on the establishment of the
ozone screen and the invasion of land leaves open the possibility that a causal

Unfortunately, nitric oxide is also a common atmospheric pollutant, produced by
automobile exhausts and industrial plants, which reduces the protective ozone
screen.
