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.

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.
