Ozone layer and global warming relationship

Can ozone depletion and global warming interact to produce rapid climate change?

ozone layer and global warming relationship

In this paper we will attempt to examine the relationship between global warming and ozone layer depletion, subsequently try to look at the possible solutions. 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. Ozone depletion and global warming are both man-made and interconnected, There is also evidence that ozone depletion is masking global warming, demonstrating the correlation between ozone depletion and global warming but also.

Global Warming And Ozone Layer Depletion |

Ozone depletion occurs when chlorofluorocarbons CFCs and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere see details below. Ozone sits in the upper atmosphere and absorbs ultraviolet radiaton, another type of solar energy that's harmful to humans, animals and plants. CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

How ozone works How ozone is distributed in the atmosphere. NOAA The sun emits electromagnetic radiation at different wavelengths, meaning energy at different intensities.

The atmosphere acts like a multi-layer shield that protects Earth from dangerous solar radiation. Ozone is found in two different parts of our atmosphere. It is found in the lower atmosphere troposphere and has nothing to do with the "ozone hole.

Can ozone depletion and global warming interact to produce rapid climate change?

The stratospheric ozone layer absorbs ultraviolet UV radiation, preventing dangerous UV rays from hitting Earth's surface and harming living organisms. UV rays cannot be seen or felt, but they are very powerful and change the chemical structure of molecules. UV radiation plays a small role in global warming because its quantity is not enough to cause the excess heat trapped in the atmosphere.

UV radiation represents a small percentage of the energy from the sun, and is not highly absorbed or scattered in the atmosphere—especially when compared with other wavelengths, like infrared. But, ozone depletion is also concerning because it directly impacts the health of humans, and other living organisms. The ozone hole The ozone hole. 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.

Stratospheric ozone is constantly produced by the action of the sun's ultraviolet radiation on oxygen molecules known as photochemical reactions. Although ozone is created primarily at tropical latitudes, large-scale air circulation patterns in the lower stratosphere move ozone toward the poles, where its concentration builds up. In addition to this global motion, strong winter polar vortices are also important to concentrating ozone at the poles.

During the continuously dark polar winter, the air inside the polar vortices becomes extremely cold, a necessary condition for polar stratospheric cloud formation. Polar stratospheric clouds create the conditions for drastic ozone destruction, providing a surface for chlorine to change into ozone-destroying form.

They generally last until the sun comes up in the spring. NASA In the s, scientists discovered that the ozone layer was thinning in the lower stratosphere, with particularly dramatic ozone loss—known as the "ozone hole"—in the Antarctic spring September and October.

These chemicals can remain in the atmosphere for decades to over a century.

At the poles, CFCs attach to ice particles in clouds. When the sun comes out again in the polar spring, the ice particles melt, releasing the ozone-depleting molecules from the ice particle surfaces.

Once released, these ozone-destroying molecules do their dirty work, breaking apart the molecular bonds in UV radiation-absorbing ozone.

United Nations Environmental Program. While in the case of atmospheric ozone depletion, in a situation of high uncertainty and against strong resistance, climate change regulation attempts at the international level such as the Kyoto Protocol have failed to reduce global emissions. US manufacturer DuPont acted more quickly than their European counterparts.

They pointed out that the goal of the IPCC is to fairly represent the complete range of credible scientific opinion and if possible a consensus view. Three years later the report made an impact with the assessment of the state of the art in climate research, an assessment of the threat of climate change itself as well as suggestions for clear emissions reduction targets, even though he argues there was no consensus, and attributed the success of the report to strong precautionary action, and that no scientific outsiders or climate change skeptics were involved.

Public opinion on climate change The two atmospheric problems have achieved significantly different levels of understanding by the public, including both the basic science and policy issues. Americans voluntarily switched away from aerosol sprays before legislation was enforced, while climate change has failed in achieving a broader scientific comprehension and in raising comparable concern. This was not the case with global warming. The Earth's ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres 12 to 19 mi above Earth.

Sheldon Ungar, a Canadian sociologist, assumes that while the quantity of specialized knowledge is exploding, in contrast scientific ignorance among lay people is the norm and even increasing. Public opinion failed to tie climate change to concrete events which could be used as a threshold or beacon to signify immediate danger. The scientific assessment of the ozone problem also had large uncertainties; both the ozone content of the upper atmosphere and its depletion are complicated to measure and the link between ozone depletion and rates of enhanced skin cancer is rather weak.
