Climate Change and Ozone Layer

Flashcards covering key vocabulary and concepts related to climate change, ozone depletion, and international treaties.

Dobson Units

A measurement unit used to quantify the amount of ozone in the atmosphere, where 1 Dobson unit represents a layer of ozone 0.01 mm thick at ground level.

Ozone Depleting Substances (ODSs)

Chemical compounds that contribute to the depletion of the ozone layer.

Chlorofluorocarbons (CFCs)

Man-made compounds that have contributed significantly to ozone layer depletion.

Montreal Protocol

An international treaty adopted to phase out substances responsible for ozone depletion.

Kyoto Protocol

An international treaty committing state parties to reduce greenhouse gas emissions.

Polar Stratospheric Clouds (PSCs)

Clouds that form in polar regions and play a critical role in ozone depletion when exposed to sunlight.

Greenhouse Gases (GHGs)

Gases that trap heat in the atmosphere and contribute to global warming.

Ozone Layer

A region of Earth's stratosphere that contains a high concentration of ozone, protecting life by blocking ultraviolet radiation.

Ultraviolet (UV) Radiation

A type of energy produced by the sun that can have harmful effects on living organisms.

Climate Action Plans

Strategies developed by nations to mitigate climate change through emission reductions and sustainability efforts.
