Scenario

Al Gore, the 45th Vice President of the United and renowned environmentalist, has hired you. Many people believe that global warming is a fallacy and that the current uproar about drastic climatic changes is mere political rhetoric championed by extremists. Their belief is that hydrocarbons released into our atmosphere over the past century are the main cause of major climate changes that have contributed to global warming.

Mr. Gore needs to demonstrate that there is merit to the present claim of a global warming crisis. To do this, he has asked you to create a visual presentation of the contiguous U.S. climatological changes for the past 100 years in yearly increments. Also, Mr. Gore would like you to create a visualization story utilizing qualitative data extracted from the various sources of 2015 Greenhouse Gas Emissions. The audiences that he intends to present your findings to are the naysayers both in Congress and key industrialists.

Instructions

Tableau Presentation

Create a Tableau visualization story that links the measures of quantitative and qualitative data necessary to support the communication Mr. Gore requires. Use visualization stories and visualization tools to capture key insights and express them in business terms.

• Utilize appropriate visualizations in your presentation, based upon your analysis of Tableau visualization options and audience needs.
• Create data sets that will be used in this presentation.
• Chart the average, minimum, and maximum temperatures, and precipitation levels in the contiguous U.S.
• Present changes in the occurrence of drought in the same 100 year time span using the U.S. Drought Severity Index (PDSI) rankings as compared to the 20th Century averages.
• Apply the proper visualizations for the qualitative data found on Greenhouse Gas Emissions.

Word Document

After your research and creation of the visualization story, draft a summary in Word addressing the following information:

• Identify the needs of your audience.
• Explain your presentation and the justification for the data sets you used.
• Discuss presentation of data using editorial thinking and communication.
• Identify data found to be unavailable, and provide an explanation of why it is not available.
• Devise a plan to turn insight derived from the data into actions to meet the communication goals.
• Explain what makes this insight actionable.
