Explain how the global radiation budget is affected by sulfate aerosols compared to CO2.

Watch the movie “Global Dimming” and read the following arguments at skeptical science.com as to why there was no mid-20th Century warming.  https://www.skepticalscience.com/global-cooling-mid-20th-century-advanced.htmLinks to an external site.

Combine what you learn from this movie with the arguments to create a Personal Movie Discussion Board Essay/Blog for others to read. Use separate paragraphs for each item and keep your responses organized. As part of your essay/blog, include the following:

  1. Describe four different data sets from the movie that led scientists to the discovery of global dimming, and explain how the Clean Air Act helped to eliminate this dimming.
  2. Explain how the 3 day period after 9/11 and the related airplane contrails were a factor in the discovery of global dimming. Also describe how they determined the temperature rise during this 3 day period?
  3. Explain how the global radiation budget is affected by sulfate aerosols compared to CO2. In your response describe how CO2 affects outgoing infrared radiation, describe how sulfate aerosols affect the incoming solar radiation, and explain the process of what happens when we reduce pollution emissions and airplane contrails.
  4. Discuss the three most interesting things that struck you the most while watching the film. Explore your thoughts in depth on these three things. (100-200 words total minimum)
