QUIZ
1. Why is a change of a few degrees in average
global temperatures more concerning than dayto-day weather changes of a few degrees?
a) This means that temperatures are increasing all around
the globe, not just in a few areas.
b) Weather changes of a few degrees rarely happen so it
is not something we worry about.
c) Even a slight increase in average global temperatures
means we should have more weather extremes that can
cause problems.
d) Climate has never changed in the past so if it is
changing now by even just a few degrees we know
something is wrong.
2. How are ice cores used in climate
science?
a) They are used to cool areas that are warming
too quickly.
b) Excess CO2 that is removed from the
atmosphere can be stored there.
c) Scientists set out ice cores and monitor how
quickly they melt to get an estimate of the
effects of climate change.
d) Bubbles trapped in the ice reveal clues about
the atmosphere at the time each bubble formed.
3. What is the evidence in the North
Woods of Minnesota that suggest climate
is changing?
a) The range of some trees is moving
northward.
b) Deer have left the area.
c) Fewer fires are occurring in what is
naturally a fire adapted ecosystem.
d) Prairie has replaced the forest along its
northern edge.
4. Global warming is expected to cause
sea level to rise due to
a) erosion of coastlines
b) the thawing of the permafrost
c) the increased flow rate of rivers that will
take more water to the oceans of the
world
d) melting glacier and land-based ice and
the thermal expansion of water as it
warms
5. One of the paths we must follow to
address global warming is called mitigation.
This is referring to:
a) Things that we can do to lessen the potential for
future warming
b) International agreements to provide money to
help poorer nations cope with the change
c) Taking steps to adjust to the warming that we
have already experienced
d) Making preparations to deal with inevitable
warming that will come

How it All Ends
This unfortunately has become a political issue rather than just a scientific one
and that muddies the waters when we are trying to figure out what to do –
reduce your own footprint but stay educated on the issue and urge your leaders
to do what you think is needed.
