The Ozone Layer and Climate Change Essays

In the late 1970’s scientists concluded that products releasing carbonflourochloride (CFC) was causing the ozone to deplete. The ozone layer is a protective layer from the sun’s rays and depleting the ozone layer allowed the stronger, harmful to health on earth, rays to get through. International action was taken in 1987 and the Montreal Protocol came into being. It was an international treaty to phase out CFC producing products. It went into effect in 1988 and has achieved international success. Once the Montreal Protocol had been agreed to the World Health Organization released information on the harmful effects CFC’s were having on the ozone

Did you know that with all this talk about global warming, and the disappearing of the ozone layer, the root of the problem is us? Yes, we’re the cause of all those problems. We keep putting something called greenhouse gases into the air. A few greenhouse gases are water vapor, carbon dioxide, and methane. While some climate change is natural, humans need to be careful about greenhouse gases because ecosystems are changing, sea levels are rising, and global average temperature increased by more than 1.3 degrees Fahrenheit over the last century.

In 1988, the National Aeronautics and Space Administration had conclusive proof products adding to the output of carbon dioxide and methane gases in the atmosphere were causing the earth to warm; and, if not stopped will make it inhabitable for human life. In the 1970’s the United States had conclusive proof that products releasing Chlorofluorocarbons into the atmosphere were causing the ozone layer to deplete; and, that if continued would be dangerous for human life. The United States took international global action, by joining the Montreal Protocol, to phase out the products producing chlorofluorocarbon and the ozone layer has been successfully replenished .

Phrases such as “climate change” and “global warming” are often thrown around on the news and in politics; however their meaning and significance was never clear to me. I enjoyed my reading of the Susan Solomon interview because, it was very informative and easy to understand. Solomon’s outstanding achievements as a female scientist are inspiring and remarkable. Her groundbreaking studies in Antarctica concerning the ozone hole, prove to us how important it is to take care of our planet. Human produced substances known as CFCs (chlorofluorocarbons) have damaged our ozone beyond repair. It is hard to believe that humans can be so careless as to destroy their own Earth. Thankfully, “the nations of the world agreed to stop producing CFCs” in 1987.

Below are four photos of the ozone layer at different times. The purple parts of the pictures represent the thinnest parts of the ozone layer. The blue parts are the next thinnest part of the ozone layer. The green parts of the pictures represent the normal thickness of the ozone layer. The red and yellow parts represent a buildup of ozone. The reason for the dramatic decrease in the ozone between September 17, 1979 and October 7, 1989 (top left and top right photos) is because of the introduction of CFCs or chlorofluorocarbons (Alford).

Climate change, specifically in reference to C02 Emissions released by human use of fossil fuels and their consequential effects on the environment, is perhaps one of the most pressing issues we, not just as Americans, but as human beings face in our lifetimes. Though it may sound like a sensationalist statement the facts are hard to deny. In May of 2013, the National Oceanic and Atmospheric Administration

Three scientific principles of sustainability are relying on solar energy, preserving biodiversity, and recycling chemicals that we use. The sun warms the planet and provides energy. Biodiversity does not allow an overpopulation of a species to occur. Chemical recycling is the circulation of necessary chemicals from the environment through organisms and back to the environment.

The discovery of fossil fuels led to times of intense economic and social globalization, as well as several advances in scientific knowledge. With these advanced technologies humans could create and do more than at any other point in history. Because of these fossil fuels, the world is how it is today. But these technologies have a setback. In recent decades, human activities have released ever-greater volumes of greenhouse gases into earth’s atmosphere, enough to affect global climate.

In the early 20th century people knew that they could cause changes to their local climates by, for example, leveling large portions of forests and over ploughing fields; but very few thought human action could affect the global climate. It wasn’t until 1958 that humans began to record measurements of carbon dioxide in the atmosphere, which revealed an increasing amount. This new data scientists were recording supported the idea of global climate change as real and that increased green house gases in the atmosphere would in fact cause the world’s climate to become warmer. In the 1980’s the world’s global temperature started to climb at a faster pace than seen before which helped the issue gain attention among the public, the scientific community,

When the ozone layer depletes and the earth is exposed to more UV radiation, there are known to be harmful effects on animals and ecosystems. In domesticated animals, it is common to see increased cases of skin and eye cancers when UV radiation levels increase. However, the effects of CFCs and ozone depletion are more noticeable in marine life. For example, many plankton are affected by the increased UV radiation, which can cause some of them to die. In marine ecosystems, plankton are the first level of the food chain, so their decreasing population will likely disrupt the saltwater and freshwater ecosystems (B.C. Air Quality, n.d.). It has also been found that to many animals, such as the sea urchin, UV radiation can act as a teratogen (see picture to the right), which causes damage to their developing embryos, which may result in a less healthy population in the long run. Also, it has been found that in some marine animals, UV radiation can act as an endocrine disrupter, and cause abnormalities in the hormone function of those animals. As a result of damaged embryos and hormone functions, populations of these animals may decrease, which will then damage food chains and ecosystems (Auby,

Earth is an immeasurably complex planet, and the processes that make it so are equally as intricate. It is this same intricacy, however, that makes the Earth so vulnerable to even the slightest variation in overall temperature or change within the gases that which compose the atmosphere. What We Know About Climate Change by Kerry Emanuel aims to address this issue of Earth’s vulnerability head-on as it suggests the plausible causes for the undeniable planetary warming observed in the last century all the while proposing pragmatic solutions to discontinue the unnatural processes credited with the abnormal warming.

Current data reveals that the concentration of Carbon Dioxide in the earth's atmosphere is approximately 387 parts per million, which is roughly a 31% increase in the period 1750 to 2009. Consequently, it is evident that such increases in temperatures have caused a warmer planet (7). It is also evident that it is impossible to reverse the developments of industrial revolution. This means that as the advancements of industrial revolution continue and as energy demands increases, it is possible that this trend of climate change will continue for decades to come (McAloon, 8). The consent of the climate research community is that it most likely already affects climate noticeably and will compel significant

The earth is a beautiful and extraordinary planet, but are we treating it right? For the past 20 decades, temperatures have been rising along with hundreds of factors contributing to it. Climate change concerns the public as they wonder if its occurring, how much has occurred in the modern era, what has caused it, what the effects will be if we don’t do anything about it and much more. Many people and scientist agree that mankind is the number one cause of climate change. Humans have influenced this by greenhouse gases, methane nitrous oxide.

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere, causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by a former NASA climate scientist, James E. Hansen, explaining the effects of climate change on Earth today. Although many believe Hansen’s theories in the paper are quite far-fetched, the author mentions, “Despite any reservations they might have about the new paper, virtually all climate scientists agree with Dr. Hansen’s group that society is not moving fast enough to reduce emissions of greenhouse gases, posing grave risks” (Gillis). Gillis validates the fact that climate change has been rapidly expanding throughout Earth and society has not been able to reduce it fast enough. Many negative risks are being posed and will continue to mount if the issue of climate change is not taken seriously. Although climate change negatively affects nearly all aspects of Earth, it poses a big
