I’m working on a environmental science question and need guidance to help me understand better.

Listen to this lecture from Dr. Kevin Trenberth from NCAR

1. How does Dr. Trenberth use the bell curves of temperature to explain extreme heat events?
2. True or False: When we compared the number of days of hot records with the number of days of cold records in 2010, 2011 and 2012, we see higher ratios along time.
3. What is the “air conditioner” of Earth?
4. How does relative humidity over the ocean change with increasing temperature? How does the amount of water vapor in the atmosphere change?
5. Use your words to explain: Why global warming can lead to both heavy rain and drought at the same time?
6. Use your words to explain: Why increasing the global average temperature by 0.85 C (seems very small, right?), it can influences our everyday life?
