While the Antarctic ozone hole has a relatively small effect on global ozone, the hole has generated a great deal of public interest because: Many have worried that ozone holes might start appearing over other areas of the globe, though to date the only other large-scale depletion is a smaller ozone "dimple" observed during the Arctic spring ...
Pictured left: Image of the largest Antarctic ozone hole ever recorded (September 2006). 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.
The Scientific Assessment of Ozone Depletion is a sequence of reports sponsored by WMO/UNEP. The most recent report is from 2018. The most recent report is from 2018. The reports were set up to inform the Montreal Protocol and amendments about ozone depletion .
The Weather Channel A hole in our atmosphere more than twice the size of the United States is finally beginning to close up, and might even be completely gone by the end of the century, according ...
The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, [13] as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, [23] damage to plants, and reduction of plankton populations in the ocean's photic zone. This was ...
Acute inhalation injury may result from frequent and widespread use of household cleaning agents and industrial gases (including chlorine and ammonia).The airways and lungs receive continuous first-pass exposure to non-toxic and irritant or toxic gases via inhalation.
The largest Antarctic ozone hole recorded (September 1985) 2012 retrospective video by NASA on the Montreal Protocol The Montreal Protocol on Substances That Deplete the Ozone Layer [2] is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
This cooling is projected to result in a relative rise in ozone (O 3) depletion in the polar region, as well as an increase in the frequency of ozone holes. [38] Ozone depletion, on the other hand, is a radiative forcing of the climate system. Two opposite effects exist: Reduced ozone causes the stratosphere to absorb less solar radiation ...
