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, 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 ozone hole.
There are various ways in which ozone depletion and climate change are interconnected, but ozone depletion is not a primary cause of climate change. The Earth's atmospheric ozone has two effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.
Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem.
The ozone layer is on track to fully recover from its depletion within the next four decades, a panel of scientists gathered by the United Nations said on Monday. U.N.: Depletion of ozone layer ...
Low level ozone, or tropospheric ozone, is the most concerning type of ozone pollution in urban areas and is increasing in general. Ozone pollution in urban areas affects denser populations, and is worsened by high populations of vehicles, which emit pollutants NO 2 and VOCs, the main contributors to problematic ozone levels.
Atmospheric conditions are expected to be favorable for producing high levels of ozone air pollution in the Dallas-Fort Worth area on Friday. You can help prevent ozone pollution by sharing a ride ...

Ground-level ozone ( O3 ), also known as surface-level ozone and tropospheric ozone, is a trace gas in the troposphere (the lowest level of the Earth's atmosphere ), with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas. [1] [2] Ozone is also an important constituent of the ...
