Q1. [ 2 pts ] In the Climate Insights 101 Introduction, review items 11-14 on the Glossary and the definitions of the terms “Climate,” “Weather” & “Climate Trend.” Then review this short video animation about weather and climate which addresses these same concepts in a slightly different way:

QUESTION: Enter a letter (W, C, or T) in the yellow blanks below to indicate whether the phenomenon being described is an example of W = weather, C = Climate, or T = a Climate Trend
Over the last 130 years, global temperature has risen almost 1 degree Celsius..
Over 4 inches of rain fell on September 4, 2014 at Arivaca, AZ (62 miles southwest of Tucson) in a rainstorm fed by moisture from Hurricane Norbert.

YES NO NOT SURE
QUESTIONS ON LESSON 1
Q3. [3 pts] Long before the late 1950s when Dr. Charles David Keeling began his famous measurements of CO2, three scientists had already published important findings about carbon dioxide.
Enter the decade (e.g., “1960s”) during which each of these findings took place:
= the decade during which it was demonstrated that carbon dioxide has the ability to absorb infrared radiation that is being radiated from a heat source
= the decade in which it was first suggested that an Earth with no atmosphere would be colder than an earth WITH an atmosphere.
= the decade during which it was first calculated that burning fossil fuels at a rapid rate would warm the Earth up significantly
Q4 [3 pts] Briefly describe one important thing that LESSON 1 explained about the greenhouse gas WATER VAPOR with respect to its influence on warming:
Q5 [2 pt ] Which of the greenhouse gases described in Lesson 1 is the most likely gas to be released into the atmosphere at the “beginning” of the chain of events that produces a fast-food hamburger? Why?
Q6 [3 pts ] Is the following a correct statement or not? State yes or no, and briefly explain why it is correct OR what part of it is not correct:
“Greenhouse gases absorb outgoing solar shortwave radiation and some of it is then re-emitted to the surface, temporarily “trapping” heat in the atmosphere.”
Q7. [2 pts] Type in ONE QUOTE from either the INTRODUCTION or LESSON 1 that made an impression on you, surprised you, taught you something new, or gave you a new insight, or explained things in a way that you found especially interesting and/or easy to remember.
