Lesson details

Key learning points

  1. There is a correlation between increasing amounts of atmospheric carbon dioxide and a rising average global temperature.
  2. Increases in atmospheric carbon dioxide have been caused by human activity.
  3. Overwhelming evidence shows human activity is responsible for the rapid global warming of the last 200 years.
  4. Global warming measurements and conclusions are reliable despite some unavoidable uncertainty in measured values.
  5. Carbon footprints measure the annual greenhouse gas emissions of individuals, industry and nations.

Keywords

  • Average global temperature - the average of all the temperatures across the world over a year

  • Atmospheric CO₂ - carbon dioxide that is in the atmosphere

  • Uncertainty - the biggest possible difference between a measured value and the true value of the quantity being measured

  • Reliability - the certainty with which a measurement or conclusion will remain the same when it is checked

Common misconception

As individuals we are helpless in combatting climate change. Technology alone can solve climate issues.

Emphasise the impact of collective individual actions, especially in supporting national and international actions (including legislation) that cause appropriate change.
