There are many initiatives (individual, societal, governmental) that attempt to address climate change. SNC2D – Earth and Space Science: Climate Change Big Idea Questions (You should be able to answer these!) 1. What’s the difference between climate and weather? 2. What natural factors influence climate? 3. How does the natural greenhouse effect work? What is the theory of the anthropogenic greenhouse effect? 4. Name 3 sources of evidence for global climate change, and explain the importance and limitations of each kind of data. 5. Give an example of how feedback can help increase the effect of climate changes. 6. How might changes in water supply and temperature affect agriculture or the health of humans and wildlife? 7. Give 2 examples each of individual initiatives and societal/governmental initiatives to address climate change.
