If Global Temperature Rises by 4℃


An interactive Model/Simulation to observe the effects of a global temperature increase of 4°C on human health, agriculture, forests, oceans and marine ecosystems, permafrost, water availability, and extreme climate events.

Students will observe and discuss how a global temperature rise of 4°C will affect different regions in the world. They will learn about specific impacts such as the spread of vector-borne diseases, loss of forests due to forest fires or droughts, changes in crop productivity and food production, and flooding of coastal areas due to sea-level rise.

Use this tool to help your students find answers to:

  1. What is permafrost? How would a 4°C global temperature rise affect permafrost in Canada and Alaska? What are the potential consequences?
  2. Discuss the potential impact of a 4°C global temperature rise on water availability in Asian countries.
  3. Describe the possible effects of a 4°C global temperature rise on crop yields in South America.
  4. Which regions of the world might be adversely affected by forest fires that are caused by climate change?
