Global Warming

Green House Gases
Global Warming is a concern for every persons living on our earth. The earth is naturally heated by the greenhouse effect. The greenhouse effect simply put is there is a mixture of gases in our earth's atmosphere. The suns rays then travel through this barrier of gases known as the ozone. These rays then bounce off of the earth's surface and then back into the air. About a third of these rays are trapped in the atmosphere which then heats the earth to an average temperature of sixty digress Fahrenheit (Schank, 177). The problem we, the world are facing is with the burning of fossil fuels such as gas, coal and natural gas produces carbon dioxide. Carbon dioxide is then absorbed into the atmosphere. With the unnatural balance of gases in the atmosphere more heat is than trapped resulting in a global rise in temperature. The effects of a rise in temperature are the polar ice caps melting, thus resulting in a rise in seal level which effect low lying coasts all around the world, jet streams and changes in "normal" weather. Other effects of global warming have an adverse effect on vegetation and the spread of famine and mortality rates. "It is estimated that since the 1970s average global surface temperatures have increased at a rate of .35 degrees per decade" (Schank, 178). If something is not done in the near future to reduce green house gases the world is in trouble.
"According to President Bush he is addressing this matter, Bush has directed a Cabinet-level review of U.S. climate change policy. Members of the Cabinet, the Vice President, and senior White House staff have been meeting to examine the science, technologies, current U.S. efforts, and a wide range of innovative options for addressing concentrations of greenhouse gases in the atmosphere"(U.S. Department of State, 1). According to The Climate Change Report issued from The Department of State America has pursued many options and steps in attempts to lower emissions of...
