Yes and no. The ozone hole is basically a human-caused hole in the ozone layer above the South Pole during the Southern Hemisphere’s spring. The ozone layer, which lies high in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun. Human activities effectively punched a hole in it, through the […]
Sep 15, 2021 · In 1985, governments adopted the Vienna Convention for the Protection of the Ozone Layer, which provided the framework for the Montreal Protocol to phase out ozone-depleting substances, including chlorofluorocarbons (CFCs). The Protocol came into effect in 1989 and by 2008, it was the first and only UN environmental agreement to be ratified by every country in the world.
This graphic and data is sourced from the 2018 update report from the Scientific Assessment of Ozone Depletion. 1 The report is prepared and updated every four years by the Scientific Assessment Panel (SAP) of the Montreal Protocol on Substances that Deplete the Ozone Layer, formed by the UN Environment Programme in collaboration with the World Meteorological Organization and National Oceanic and Atmospheric Administration (NOAA).
2 days ago · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Click any map image to bring up a new page with a high-resolution image.
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 with global warming.
Jul 16, 2008 · The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth's polar regions. People, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the Earth's surface—where it causes health problems, from eye damage to skin cancer.
Jun 14, 2024 · Ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules. Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.
