Sentences with phrase «destroy ozone molecules»

Once water vapor gets into the normally dry stratosphere, it can in theory interact with manmade chlorine compounds known as chlorofluorocarbons, or CFC's, to destroy ozone molecules.

As many of you will know, and perhaps recall from living memory, alarm bells started ringing when pioneering research by a group of brilliant chemists (Frank Sherwood Rowland, Mario Molina and Paul Crutzen, who were jointly awarded the Nobel Prize for Chemistry in 1995) showed that chlorofluorocarbons (CFCs), a family of chemicals used in many everyday applications such as refrigeration, air conditioning and aerosols, were destroying the ozone molecules which make up the protective layer shielding Earth from the sun's harmful rays.

Alarm was raised in the 1970s about the state of this protective layer when scientists such as Mario Molina and F. Sherwood Rowland discovered that chemicals, including chlorofluorocarbons (CFCs) were destroying ozone molecules (Chasek et al 164)(Mossos 1).

Not exact matches

10 Unfortunately, nacreous clouds also support chemical reactions that convert benign chlorine - containing molecules into a form that destroys Earth's ozone layer.

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.»

In 1986, Solomon showed that the ozone was being destroyed by the presence of molecules that contain chlorine and bromine, which come from chlorofluorocarbons (CFCs).

Also, the overall number of ozone molecules destroyed in a vertical column of air was pretty much the same as the number of molecules transported into this column by the average poleward and downward transport of air in the stratosphere.

We might not be able to see the CO2 rising into the atmosphere just as we were not able to see the CFCs that were going into the Ozone layer and destroying it like little Pac - Men gobbling away at these molecules that protect us from the suns more caustic rays.

These molecules also react with chlorine containing gases, converting them into forms that destroy ozone as well.

Water vapor breaks down in the stratosphere, releasing reactive hydrogen oxide molecules that destroy ozone.

The CFC molecules that destroy ozone also trap heat, but the thinning of the ozone layer does not by itself make the Earth's surface hotter.
