Major Contribution

Question 1

This week we’ll examine ancient societies, like the Harappans and Mayans, that flourished and then rapidly declined. Historians, archaeologists, scientists, and others are still discovering clues about what might have contributed to these societies decline. Many point to climate change as a significant factor. What do you think? Are there lessons to be learned from these ancient civilizations? Remember to cite at least two sources

Question 2

1. According Rockstrom et al, what is a safe operating space for humanity? Do you think if there are any other planetary systems that are missing in their framework? If so, what are they?
2. According to Hsiang et al, how can climate change cause economic damage in the US? In your answer, please be specific about the spatial variations, and highlight the implication on Arizona.
