concentration at http://co2now.org/ Also, read the section on global
warming in Chapter 11 of your textbook. Compare current CO2 levels to
the highest concentrations from the past 450,000 years. Based on these
websites, and the textbook, answer the following questions: What is
the current CO2 concentration in parts per million (ppm)? Is this
higher or lower than the highs over the past 450,000 years? From what
three sources do humans add CO2 to the atmosphere? What two sources
take CO2 out of the atmosphere? How does deforestation contribute to
the global warming process? In your opinion, are humans contributing
to global warming, or is it just a natural part of the cycle? Defend
your answer to question #6. (There is no right or wrong response to
this last question; you will be judged on how well you present your
argument.) Be sure your paper is 2-3 pages long, cites credible
sources, answers all questions with complete sentences and paragraphs,
and follows CSU-Globalâ€™s guidelines for writing and APA style. Your
paper must include a title page, be double spaced, and have 1-inch
margins. Let me know what information I can provide from the textbook.
Here’s a snippet of the paper.
When it comes to understanding climate change, health and extreme weather, the facts are very clear. Our planet is communicating to us with drought, fire, record heat and storms. These are the symptoms of global warming according to scientists. Carbon pollution is the major factor, which is making the world to become hotter, leading to higher chances of drought, floods, weather disasters and deterioration of our health. Earth’s temperature is increasing and this trend is unmistakable and clear. For the past 35 years, there has been an increase in temperature every year, these are higher temperatures than the average in the 20th century. On record, the warmest years have all taken place since 1998, with the hottest year to be ever recorded since global record temperature started to be recorded being 2012 (What the world needs to watch, 2013). Globally, there has been an increase in the average ground temperature by more than 1 degree Fahrenheit from the year 1800. A major of this increase has taken place just over the last three decades.
During the past 450,000 years, carbon dioxide concentration ranged between 180 -280 ppm. It has been noted that the planet was warmer when carbon dioxide concentration was at the highest. Currently the carbon dioxide level as of November 2013 is 395.11 parts per million. This is the highest concentration, higher than any highs for the last 450,000 years (What the world needs to watch, 2013). The ice in the Antarctic as availed evidence of the ancient carbon concentration and temperature through the analysis of small air bubbles trapped during snow accumulation. These small traces of air provide carbon dioxide concentration records overtime. There exist a close association between carbon dioxide concentration and the average planet temperature.
