reaching about -60°C at the top. –Tropopause - Transition boundary that limits mixing between the troposphere & upper zones. Structure of the Atmosphere: A Layered Envelope • Stratosphere – Extends from tropopause to about 45 km. – Contains the ozone layer (17-26 km): • Blocks more than 99% of the solar UV radiation from reaching the earth’s surface. – Composition is very similar to that of troposphere except for: •

limited resources. Globalization has had diverse implications for environmental issues such as, pollution, deforestation, water resources climate change, and biodiversity loss. The rampant environmental problems have become the subject of international efforts because the effects are felt globally. The negative impacts of globalization focus on the destruction on the environment that is export-oriented. On the other hand, the positive impacts are the multinational companies research into technology that

waste. * Fluorinated Gases: Hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for ozone-depleting substances (i.e., CFCs, HCFCs, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred

of shale needs to be, banned everywhere until further testing can actually be done to determine how safe it is to people and the environment. The US is participating in this method called fracking to extract energy sources from our own land in an effort to cut down dependence on foreign energy. As it sounds great that it will help our economy and to produce our own oil and natural gas wells but, at

GLOBAL WARMING: Energy, Fall 2005 v30 i4 p36(2) It could get a lot warmer. (GLOBAL WARMING) Full Text: COPYRIGHT 2005 Business Communications Company, Inc. If humans continue to use fossil fuels in a business as usual manner for the next few centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar to 14.5 degrees warmer than current day. These are the stunning results of climate and carbon cycle model simulations

into space. The rest reaches the planet's surface and is reflected upward again as a type of slow-moving energy called infrared radiation.The heat caused by infrared radiation is absorbed by "greenhouse gases" such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.Although greenhouse gases make up only about 1 percent of the Earth's atmosphere, they regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet

Overexposure to the sun is a significant global health issue. The atmosphere provides a natural protection against harmful ultraviolet (UV) rays that are emitted by the sun. However, depletion of the ozone layer has decreased that natural protection, leading to many health problems as a result (United States Environmental Protection Agency, 2010). Skin cancers, premature aging, cataracts and other eye damage, and problems with the immune system are all problems associated with overexposure to
