Sentences with phrase «less ozone in the stratosphere»

33 OZONE DEPLETION IN THE STRATOSPHERE Less ozone in the stratosphere allows for more harmful UV radiation to reach the earth's surface.

Not exact matches

One driver of temperatures in this region is the abundance and variability of ozone, but water vapor, volcanic aerosols, and dynamical changes such as the Quasi - Biennial Oscillation (QBO) are also significant; anthropogenic increases in other greenhouse gases such as carbon dioxide play a lesser but significant role in the lower stratosphere.

The various kinds of evidence examined by the panel suggest that the troposphere actually may have warmed much less rapidly than the surface from 1979 into the late 1990s, due both to natural causes (e.g., the sequence of volcanic eruptions that occurred within this particular 20 - year period) and human activities (e.g., the cooling of the upper part of the troposphere resulting from ozone depletion in the stratosphere).

Another pathway even less studied is caused by the energetic particle rain at polar regions, where HOₓ and NOₓ chemical species are created in the polar regions of the thermosphere and mesosphere and transported down to the stratosphere where they destroy ozone.

You introduced ozone in an attempt to explain away the inconvenient fact that the stratosphere cooled when the sun was more active and is now warming whilst the sun is less active.
