what is the relationship between global warming and ozone depletion?

The ozone hole itself has a minor cooling effect (about 2 percent of the warming effect of greenhouses gases) because ozone in the stratosphere absorbs heat radiated to space by gases in a lower layer of Earth's atmosphere (the upper troposphere).

Changes in climate can result in impacts to local air quality. Atmospheric warming associated with climate change has the potential to increase ground-level ozone in many regions, which may present challenges for compliance with the ozone standards in the future.

global warming The gradual increase in the overall temperature of Earth's atmosphere due to the greenhouse effect. This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air, many of them released by human activity.

“Global warming” refers to the long-term warming of the planet. ... “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet.

Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth's surface. ... CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer.

Global warming refers to a gradual increase in global surface temperatures and the temperature of the Earth's atmosphere. Global warming is associated with the greenhouse effect that is produced when the Earth's surface and atmosphere absorb solar energy and reradiates the energy back into space.

The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.

Usually there is a fine balance between the build up and loss of ozone. However, any decrease in the amount of ozone in the ozone layer will increase the amount of UV radiation reaching the Earth's surface, and worsen the impacts due to UV exposure. ... Finally, UV rays can damage paint, clothing and other materials.

Global warming is primarily a problem of too much carbon dioxide in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests.

“Global warming” refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere. “Climate change” refers to the increasing changes in the measures of climate over a long period of time – including precipitation, temperature, and wind patterns.

Ozone depletion and climate change are linked in a number of ways, but ozone depletion is not a major cause of climate change. Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere.

global warming The gradual increase in the overall temperature of Earth's atmosphere due to the greenhouse effect. ... greenhouse effect The warming of Earth's atmosphere due to the buildup of heat-trapping gases, such as carbon dioxide and methane.

A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface.

The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Data collected in the upper atmosphere have shown that there has been a general thinning of the ozone layer over most of the globe.

“Global warming” refers to the long-term warming of the planet. ... This is on top of about an additional 0.15 °C of warming from between 1750 and 1880. “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet.

Greenhouse gases absorb heat at relatively low altitudes and warm the surface--but they have the opposite effect in higher altitudes because they prevent heat from rising. In a cooler stratosphere, ozone loss creates a cooling effect that results in further ozone depletion.

What's the difference between global warming and climate change? Global warming is the increase of the Earth's average surface temperature due to build-up of greenhouse gases in the atmosphere. Climate change is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
