Ozone depletion

Ozone Depletion

Stratospheric ozone depletion.

Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation. In the last half-century, the chemical mechanisms operating within...

Stratospheric Ozone Depletion

There is now strong evidence that a consequence of human activities is the inadvertent accumulation of a variety of trace gases in the earth’s atmosphere. In the past decade, these global-scale changes in the chemical composition of the atmosphere have led to a very significant depletion of the stratospheric ozone layer over Antarctica in the southern spring months and also at northern latitude...
