Modeling Climate Change

Background Information

The physics, chemistry, and biology that drive Earth’s climate system are (for the most part) understood and can be modeled quantitatively. These numerical models of the climate system allow scientists to project the impacts of current and future human activities on global and regional climate.

Suggested Activities

  1. Earth’s Energy Cycle – Albedo
  2. Investigating Ice Cores
  3. Planting Trees – Law of Conservation of Mass
  4. Whither Arctic Sea Ice?

Intended Learning Outcomes

  • Differentiate between positive and negative feedbacks
  • Compare and contrast various feedbacks including arctic ice, northern march of boreal forest, thermohaline circulation, aerosols, temperature, precipitation, additional CO2, etc.
  • Design imaginary process and predict feedback on the climate system (e.g. what would be the impact of covering the Earth’s surface with white flowers? With black flowers?)
  • List key global impacts including coral bleaching, ocean acidification, drought/floods, disease, sea level rise, crop failure
  • Relate impacts to human daily life
  • Differentiate between impacts at various time scales (years/decades/centuries/millennia)
  • Map regions of climatic vulnerability
  • Compare maps of regions of climatic vulnerability to regions of greenhouse gas emissions

Applicable Standards

Science

Earth and Space Science
