A comparison of ozone depletion and global warming

Ozone (O 3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it. Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars. Ozone depletion refers to the thinning and loss of ozone whereas global warming refers to the widespread warming of average temperatures across the globe.. The ozone layer allows some energy in and some energy out. The ozone protects us from UV-B rays, which can be very harmful (these are the rays that cause skin cancer). The Difference Between Global Warming and Ozone Depletion Foreman Room 1. Global Warming and Ozone Depletion take place in two different layers of the atmosphere: Global Warming Ozone Depletion Global Warming vs. Ozone Depletion: Causes Global Warming: cars, factories, rice farming, landfills: Infrared heat enters but is trapped by the chemicals when it tries to escape.

Environmental issues are not all the same. Ozone, which is made of three oxygen atoms stuck together instead of two, which is what normal oxygen gas is made ofis vital to life on Earth. It forms a layer in the stratosphere, the second layer up in the atmosphere, that is very good at absorbing ultraviolet UV radiation from the Sun.

UV radiation severely damages organisms if enough of it reaches the surface. In the middle of the 20th century, synthetic gases known as chlorofluorocarbons CFCs became popular for use in refrigerators and aerosol products, among other applications.

They were non-toxic, and did not react easily with other substances, so they were used widely. However, their chemical stability allowed them to last long enough to drift into the stratosphere after they were emitted. Free chlorine atoms Cl were liberated, a substance that is very reactive indeed.

Over the poles, the stratosphere is cold enough for polar stratospheric clouds PSCs to form. These PSCs provided optimum conditions for the most reactive chlorine gas of all to form: It turns out that Antarctica was more favourable for ozone depletion than the Arctic, both because its temperatures were lower and because its system of wind currents prevented the ozone-depleting substances from drifting out of the area.

Before long, there was a hole in the ozone layer over Antarctica due to the PSCsand concentrations were declining in other locations too due to the basic Cl reactions.

The issue became a frontier for scientific research, and scientists Crutzen, Rowland, and Molina won the Nobel Prize in Chemistry for their work with atmospheric ozone. This movement was largely successful, and the use of CFCs has become nearly negligible, especially in developed nations.

The regulations are working: In contrast, climate change is a product of greenhouse gases such as carbon dioxide. Unlike CFCs, most of them are not synthetic, and they are released from the burning of fossil fuels coal, oil, and natural gasnot specific products such as refrigerators.

Rather than destroying a natural process, like CFCs do, they strengthen one to the point of harm: This phenomenon, which traps heat in the atmosphere, is absolutely vital, as the Earth would be too cold to support life without it. Increasing the concentrations of greenhouse gases with fossil fuels becomes too much of a good thing, though, as the greenhouse effect traps more heat, warming the planet up.

Ozone Depletion and Global Warming

Just a few degrees Celsius of warming can cause major problems, as agricultural zones, wind and ocean currents, and precipitation patterns shift. The sea level rises, submerging coastal cities. Many species go extinct, as the climate changes faster than they can adapt.

Unlike the Montreal Protocol, efforts to reduce greenhouse gas emissions have more or less failed. Fossil fuels permeate every part of our lives, and until we shift the economy to run on clean energy instead, convincing governments to commit to reductions will be difficult at best.

It remains to be seen whether or not we can successfully address this problem, like we did with ozone depletion. Although these two issues are separate, they have some interesting connections.

For example, PSCs form in cold areas of the stratosphere. Unfortunately, global warming is, paradoxically, cooling the stratosphere, as a stronger greenhouse effect means that less heat reaches the stratosphere.The Difference Between Global Warming and Ozone Depletion Foreman Room 1.

Ozone depletion vs. Global Warming • Yes, CFC’s (Chloroflourocarbons) and Ozone (O3) are both involved in ozone depletion and global warming, but ozone depletion is a separate issue from global warming Ozone Depletion vs.

Ozone depletion is a long term decrease in atmospheric ozone in the region above the lower troposphere. Its symptoms include more UV-B arriving at Earth's surface, and a larger, longer-lasting.

Human activities cause ozone depletion and global warming. Ozone (O 3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.
