Global Warming Statistics
Overview Procedures for Teachers Organizers for Students


Students research real-time and historic temperature data of U.S. and world locations, and analyze the data using mean, median, and mode averages. Students graph the data and draw conclusions by analyzing the data. Resources include Web sites with real-time data, archived data, temperature-sensitive computer graphics, meteorology, government agencies, and Earth Day information. Students use a calculator or electronic spreadsheet to compile their statistics and then graph the data using a spreadsheet or graph paper. Reasons for extreme temperature changes are explored.

On Air Resource:
WHAT'S UP WITH THE WEATHER? NOVA & FRONTLINE on global warming. Tuesday, April 18, 2000, 9:00 PM.

Grade Level: 7-12

Subject Matter:

Mathematics, Earth Science

Curricular Uses:

  • Mathematics: basic statistics, graphing, and data analysis
  • Earth Science: research causes of global warming, chemical makeup of the atmosphere, ozone, and other effects of pollution on ecology (acid rain, extreme weather patterns, animal extinctions, ocean levels rising due to polar ice caps melting)
Curricular Uses in the Extensions:
  • English: writing poetry, essays, or short stories
  • Art: visual art composition
  • Social Studies: effective communication with government representatives and agencies, study of pollution prevention laws, E.P.A regulations, how the people affect change
  • Foreign Language: written communication in language of study to pen pals in foreign countries
  • Health: effects of global warming and other results of pollution (acid rain, air changes) on the human body
  • Keyboarding: typing skills, proper format of a formal letter, attaching files to email, using word processor software like Microsoft Word
  • Economics: analyzing the cost of global warming (world economics, food prices, employment of fishermen, fish depletion, money spent on research, prevention, and cleanup)
  • Performing Arts: acting, composing and performing a song
  • Speech: persuasive speech writing and presentation


Learning Objectives



Students will be able to:

  • Identify, gather, calculate, and interpret data using mean, median, and mode
  • Graph data, showing how statistics can be skewed using different scales
  • Interpret and evaluate what the statistics show
  • Extrapolate future data from current graphs


Use of the Internet: The Internet is used as a tool for Web research, so proper use of search engines must be discussed. Teachers should preview and bookmark useful sites for students before the lesson to save time. Pages with real-time data may be refreshed to keep the current temperatures updated.
