During this period, all over the world is facing with one of the biggest problem, the Global Warming. Global Warming makes average level of Earth’s temperature increasing this is causing by two main phenomena; increasing of greenhouse gases levels all over the world and ozone depletion in the atmosphere. Greenhouse effect made up by several groups of gases that we know as greenhouse gases. In general, the levels of these gases were controlled by nature, so the level of the greenhouse gas was constant
The last problem you would think of is the depletion of the ozone layer. However, it could be the most serious problem we are facing today. The ozone is a layer of gas that forms a protective covering in the Earth’s upper atmosphere. This layer of gas is slowly diminishing each day, and causes a great concern to our safety. There are many reasons why this depletion is occurring, and chemistry is playing a huge role into helping solve this problem. Ozone composed of three oxygen atoms is an extremely
The effects of global warming are the environmental and social changes caused by human emissions of greenhouse gases. There is a scientific consensus that climate change is occurring, and that human activities are the primary driver. Many impacts of climate change have already been observed, including glacier retreat, changes in the timing of seasonal events, and changes in agricultural productivity. Some major damaging impacts that global warming has on the environment are less fresh water availability
OZONE DEPLETION BY HUMAN’S ACTIONS The ozone layer is a very important component in the atmosphere. Ozone is not the same as the oxygen humans breathe. There is very little of this gas in the atmosphere. First off, let’s begin with a definition of the ozone layer. Ozone is a hot, slightly bluish gas. It is a molecule made up of three oxygen atoms, which are very similar to the molecule we are familiar with (O2), the molecule needed for human respiration. Despite the major smog problem, about 90
introduced to the Industrial Revolution cared less about pollution and as science began to expand, the awareness of air pollution has grown havoc towards today. The most severe environmental effects from air pollution are acid rain, ozone depletion, and global climate change. These remain as one of the most possible effects that may cause cataclysm and acid rain continues to grow severe in modern-day life. Acid rain is one of the three main results from air pollution. It is described as precipitation containing
Volcanic Eruptions and Global Climate Change Abstract There has been much debate in recent decades over how much volcanic eruptions contribute to global climate change, the destruction of the ozone layer, and global warming. This electronic term paper deals with various sides of this debate. There will be a specific focus on the great nineteenth century eruptions of Tambora and Krakatoa. Table of Contents Introduction The Effects of Volcanoes on the Earth Systems in General The 18--
Global Warming and Ozone Depletion Global warming is a gradual increase in the overall temperature of the Earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide , chlorofluorocarbons and other pollutants. One of the biggest issues that is currently taking place in global warming is depletion of the ozone layer and human activities are part of the blame. The ozone layer is a layer in the earth stratosphere that contains a high concentration of
an area of specific health related and environmental concern: the human dimensions of global change. For about a decade now there has been growing scientific interest in the global environmental changes resulting from anthropogenic activity. However most of this research has focused on the scientific bases of environmental transformations with little attention to how human social responses are linked to global change. As a result, scientists and researchers alike are beginning to ask questions about
the Earth, an astronaut can look down on our home and see the thin blue ribbon that rims our planet. That transparent blanket -- our atmosphere -- makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by narrow transition zones which is the atmosphere. (Graedel 1998) The
Ozone Depletion The world's ozone is depleting on a daily base. Individuals and industries are to blame. If we don't slow down what is being introduced to the atmosphere, the effects on humans and the earth will be devastating. We must stop killing the earth's ozone by watching what CFC's get released, car pooling to control automobile emissions, and stop industries from polluting our atmosphere. The problems with a depleting ozone layer are an increase in skin cancer, global
