Sentences with phrase «destroy ozone high»

They found that water vapour and chlorine and bromine from vaporised sea salts would destroy ozone high in Earth's atmosphere at a much faster rate than it is naturally created (Earth and Planetary Science Letters, DOI: 10.1016 / j.epsl.2010.08.036).

We've changed the atmosphere in other ways, mainly by adding ozone and aerosols at the ground, and destroying ozone high in the atmosphere with CFCs.

This is important, as a molecule of ozone lost in this region has a far larger impact on climate than a molecule destroyed at higher altitudes by longer - lived gases.»

Benítez says that a supernova could have gone off at a mere 100 light - years away — close enough to have blasted Earth with high - energy cosmic rays and destroy the ozone layer.

Once aerosols are that high they can spread globally, destroy the ozone layer that protects us from ultraviolet radiation and exacerbate global warming, researchers warn.

Bromine, another ozone - destroying atom, is declining in the lower atmosphere and has stabilized higher up, according to the assessment.

In a nutshell, many of the elements being sprayed destroy the high - altitude ozone layer which used to protect the earth from UV radiation, back in the good ol' days.

They can descend down to the mid-stratosphere and destroy ozone, which leads to cooling of the high - latitude stratosphere.

HFCs have been commercialized to replace the chemicals that were destroying the ozone layer, but while HFCs do not destroy ozone, they have extremely high global warming potentials and are contributing to global climate change.

Once aerosols are that high they can spread globally, destroy the ozone layer that protects us from ultraviolet radiation and exacerbate global warming, researchers warn.»

Bromine, the ozone - depleting element found in methyl bromide, is nearly 60 times more effective at destroying ozone than the chlorine found in CFCs.9 This means that even though its atmospheric lifetime is quite short (a little over a year) 31, the immediate impact of changes in methyl bromide emissions on the ozone layer is very high compared to other chemicals.
