    Global Warming may not be on the tip of everyone's tongue, nor in the foremost part of their minds. In fact, Global Warming may not even exist. Yet its consideration is worth the taking since it could have profound impacts on the Earth, the only planetary home humans possess. Global Warming is, by the EPA definition, the progressive gradual rise of the earth s surface temperature thought to be caused by the greenhouse effect and responsible for changes in global climate patters the term is most ...

    Meghan McDonald McDonald 1 Mr. Hrk al OAC World Issues December 18 th, 2000 Global Warming Now, for the first time in Earth's history, humans may be a decisive factor in future climate change. The actions we make towards the temperature of the earth and the depletion of the ozone layer are irreversible. A warmer future could result from present-day human activities releasing large amounts of heat-trapping gases into the air. These "greenhouse gases" are part of the reason for the 1 F (. 5 C) ris...

    The Greenhouse Effect The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earth's surface absorbing and trapping heat radiation which normally escapes from the earth. They include carbon dioxide, water vapor, methane, nitrous oxide, CFC's, and other halocarbons. The earth's atmosphere goes through two processes constantly. Global cooling is the first process. This process uses the ...

    In this research paper I will attempt to explain what whippets are. I will try to give the necessary information to show the benefits and possible side effects. I will discuss a brief history of the gas and how young adults obtain the chemicals to make "whippets." Whippets are charge dispensers that deliver nitrous oxide as (en. wikipedia. org) describes. Nitrous oxide is a colorless, non-flammable gas. It has a slightly sweet taste and odor. It is non-toxic and non-irritating and when inhaled ...
  • Greenhouse Effect And The Hole In The Ozone Layer
    923 words
    The Greenhouse Effect The earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Energy from the sun drives the earth's weather and climate, and heats the earth's surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour, carbon dioxide, and other gases) trap some of the outgoing en...

    The Greenhouse Effect The Earth is kept warm by it's atmosphere, which acts rather like a woolly coat - without it, the average surface temperature would be about -18 degrees Centigrade. Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation - much like a hot pan emits heat even after it's taken away from the cooker. Some of this heat is trapped by the atmosphere, but ...
  • Anesthetics Surgical Procedure

    Anesthesia is a partial or complete loss of sensation or feeling induced by the admin- is tration of various substances. For many decade, people have used one form of an anesthetic during surgical procedures. Some people also use some of these anesthetics as recreational drugs, e. g. laughing gas (a. k. a. Nitrous Oxide). The term anesthetic literally means "without feeling." There are many different types of anesthesia, but they are usually put into three groups. These groups are gene- ral ane...

    The difference between Ozone Depletion and Global Warming Ozone Depletion The Ozone Layer is a region of the atmosphere from 19 to 48 km (12 to 30 mi) above the Earth s surface. Scientists were concerned when they discovered in the 1970 s that chemicals called chlorofluorocarbons, or CFCs long used as refrigerants and as aerosol spray propellants posed a possible threat to the ozone layer. These chlorine-containing chemicals rise and are broken down by sunlight. The chlorine reacts with and dest...

    Inhalants Solvent abuse is defined as a deliberate inhalation of an easily vaporized organic substance to achieve a distortion of consciousness (Ste ffle 1996). Any product containing a volatile substance can be used; those containing large portions are preferred. There are hundreds of chemicals, sold in thousands of products. The one thing they all have in common is that they all replace oxygen in the brain. Inhalants are classified into three categories (solvents and gases, anesthetics and nit...

    For years, scientists have warned that pollution from burning fossil fuels would cause dangerous warming of the planet. The hottest 10 years on record have all occurred since 1980. 1998 was the hottest year ever recorded. With scientists predicting more violent weather, spread of infectious diseases, and rising sea levels. According to Accu-Weather, the worlds leading commercial forecaster, Global air temperatures as measured by land-based weather stations show an increase of about 0. 45 degrees...

    Now more than ever humans are becoming a major factor in the future of climate and more importantly climate change. Human actions towards the earth and the depletion of the ozone layer are irreversible. A warmer future could result from human activities in the present by releasing massive amounts of heat trapping gases into the air. (web) These greenhouse gases are partially the reason for the 0. 5^0 C rise in the global average temperature recorded over the past 100 years. If the Earth's tempe...
