Tropospheric ozone depletion events are phenomena that reduce the concentration of ozone in the earth's troposphere. Ozone (O3) is a trace gas which has been of concern because of its unique dual role in different layers of the lower atmosphere. [1] Apart from absorbing UV-B radiation and converting solar energy into heat in the stratosphere ...
The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed on 16 September 1987, and entered into force on 1 January 1989.
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.
The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zone. This was not the case ...
Ozone ( / ˈoʊzoʊn /) (or trioxygen) is an inorganic molecule with the chemical formula O. 3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O. 2, breaking down in the lower atmosphere to O.
STS-41 launches from Kennedy Space Center, on October 6, 1990. Ulysses after deployment. Discovery lifted off on October 6 1990 at 7:47:16 a.m. EDT. Liftoff occurred 12 minutes after a two-and-a-half-hour launch window opened that day at 7:35 a.m. EDT. STS-41 featured the heaviest payload to date; Discovery weighed 117,749 kg (259,592 lb). [2]
White South Africans are South Africans of European descent. In linguistic, cultural, and historical terms, they are generally divided into the Afrikaans-speaking descendants of the Dutch East India Company's original colonists, known as Afrikaners, and the Anglophone descendants of predominantly British colonists of South Africa.
Ozone was an American magazine focusing on hip hop music coverage from the Southern United States and operated from 2002 to 2010. It was founded in Orlando, Florida in 2002 by Julia Beverly. [1] In 2006, the magazine relocated its headquarters to Atlanta .
