  2. Ozone depletion and climate change - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion_and...

    Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.

  3. Ozone depletion - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion

    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.

  4. Ground-level ozone - Wikipedia

    exert a considerable impact on global warming, because it is a key air pollutant and greenhouse gas, and; impact the production of surface level ozone (contributing again to climate change). As a result, photochemical smog pollution at the earth's surface, as well as stratospheric ozone depletion, have received a lot of attention in recent years.

  6. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    Climate change. Changes in surface air temperature over the past 50 years. [ 1] The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures. Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution.

  7. Montreal Protocol - Wikipedia

    en.wikipedia.org/wiki/Montreal_Protocol

    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.

    en.wikipedia.org/wiki/Planetary_boundaries

    Planetary boundaries. Visualizations of the Planetary Boundaries; data for September 2023 [ 1] Planetary boundaries are a framework to describe limits to the impacts of human activities on the Earth system. Beyond these limits, the environment may not be able to self-regulate anymore. This would mean the Earth system would leave the period of ...

  9. Polar vortex - Wikipedia

    en.wikipedia.org/wiki/Polar_vortex

    The tropospheric vortex increased in public visibility in 2021 as a result of extreme frigid temperatures in the central United States, with experts linking its effects to climate change. [4] Ozone depletion occurs most heavily within the polar vortices – particularly over the Southern Hemisphere – reaching a maximum depletion in the spring.
