  2. Ozone depletion - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion

    Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, [citation needed] and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. [1] The latter phenomenon is referred to as the ...

    A steady decline of about four percent in the total amount of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. Very short-lived substances (VSLS) are ozone-depleting halogen-containing substances found in the stratosphere. These substances have very short ...

    en.wikipedia.org/wiki/Ozone

    Ozone is a bent triatomic molecule with three vibrational modes: the symmetric stretch (1103.157 cm −1), bend (701.42 cm −1) and antisymmetric stretch (1042.096 cm −1). [49] The symmetric stretch and bend are weak absorbers, but the antisymmetric stretch is strong and responsible for ozone being an important minor greenhouse gas .

  8. Ozone layer - Wikipedia

    en.wikipedia.org/wiki/Ozone_layer

    The ozone layer peaks at 8 to 15 parts per million of ozone, [1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9 to 22 mi) above Earth, although its thickness varies ...

    en.wikipedia.org/wiki/Ozone_depletion_and...

    The Earth's ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth. Aant Elzinga wrote in 1996 about the consensus, that the Intergovernmental Panel on Climate Change has tried in the prior two reports a global consensus approach to climate action. [ 11 ]
