Ozone Our Global Sunscreen By Mike Carlowicz t’s not often that scientists get to conduct experiments that seem like they come out of a science fiction novel or a video game. Yet‚ that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry and circulation of the air; natural variations in temperatures

There are many other ways humans can interact with the atmosphere but I will talk mainly about how human interaction is creating holes in the ozone‚ how we have created the enhanced greenhouse effect and contributing to global warming. The ozone is a thin layer of O3 that surrounds the earth and helps to regulate climate and temperature. Without the ozone there would be a lot more insolation and the earth would probably be too hot to populate. Chlorofluorocarbons or CFC’s were used

Globalization and the Pollution Globalisation is an universal phenomenon which was introduced with the aim of integrating societies‚economies and cultures through a common link of trading policies‚technology and communication.With the advent of globalisation though the standard of economy has improved‚it also brought many new issues into concern. Brain drain‚pollution and spread of diseases are the major problems the world is facing today.For a large extend the factor behind this is globalisation

form of acid rain. Acid rain can cause great damage to human‚ animals and crops. 4. Depletion of Ozone layer: Air pollution depletes Ozone layer. Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays. Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons‚ hydro chlorofluorocarbons in the atmosphere. As ozone layer will go thin‚ it will emit harmful rays back on earth and can cause skin and eye related problems. UV

This orange layer gives way to the whitish Stratosphere and then into the Mesosphere."[1] Atmosphere diagram showing stratosphere. The layers are to scale: from Earth’s surface to the top of the stratosphere (50km) is just under 1% of Earth’s radius.

own home‚ earth. Ozone depletion‚ climate change as well as the direct effects of chemicals from industrial emissions and fuel combustion are a great threat to our planet and if nothing is done to resolve this problem soon‚ the results may be disastrous. There is a layer of chemicals twenty kilometers up in the stratosphere called the ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us‚ many living

ecosystem’s ability to maintain itself. A valuable player in the balance of the environment‚ the ozone layer‚ is facing a very serious threat by man. Chloroflourocarbons (CFCs)‚ are chemical agents commonly found in refrigerants‚ aerosol sprays‚ and in the manufacturing of Styrofoam and industrial solvents. With the rate of more than a half-million tons of CFCs being spewed into the atmosphere yearly‚ the rate of ozone depletion is rising at an alarming rate. If a global effort is not made to end the unnecessary

Greenhouse effects builds up the temperature on earth. The ozone layer of earth keeps the high beams from the sun burning the wild life and humans. Everyday the ozone layer is slowly being uncovered.
