The United Nations designates a specific theme each year for the International Day for the Preservation of the Ozone Layer to highlight different facets of ozone protection. 2015: 30 Years of Healing the Ozone Together. [6] 2016: Ozone and climate: Restored by a world united. [7] 2017: Caring for all life under the sun. [8] 2018: Keep Cool and ...
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 ...
Ozone-induced degradation will deteriorate saturated and unsaturated polymers when the plastic is exposed to atmospheric ozone. [14] A test can be conducted to see if the object has been exposed, by taking small samples for analysis using Fourier-transform infrared spectroscopy (FTIR).
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 ...
Mario José Molina-Pasquel Henríquez [a] (19 March 1943 – 7 October 2020) [7] was a Mexican physical chemist. He played a pivotal role in the discovery of the Antarctic ozone hole, and was a co-recipient of the 1995 Nobel Prize in Chemistry for his role in discovering the threat to the Earth's ozone layer from chlorofluorocarbon (CFC) gases.
The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...
World Environment Day was established in 1972 by the United Nations at the Stockholm Conference on the Human Environment (5–16 June 1972), that had resulted from discussions on the integration of human interactions and the environment. One year later, in 1973, the first WED was held with the theme "Only One Earth".
Ozoneweb is an EEA website on near real-time ozone. The website allows the general public to track air quality in a specific region and on a European level. The website displays ozone levels via a map of Europe. Background information on ozone and its health impacts are also provided. Users can monitor ozone levels in a neighbouring country or ...
