Questions on the High School Backgrounders
Backgrounder #1: Climate Change: What’s the big
deal?
Content Questions
- How has the climate changed in the last 100 years?
- What causes climate change? (What are greenhouse gases, and how
are they causing the planet to heat up?)
- How is climate change affecting the north?
- How can we reduce our greenhouse gas emissions?
Reflective Questions (Select one)
- As a northerner, what does climate change have to do with you?
What impact could it have on your future, your culture,
your way of life,
your community?
- Scientists like David Suzuki are saying that we are
going to have to make major changes in the way we
live if we really
want
to slow
down climate change. What kinds of changes to your
lifestyle would you and
your friends be willing to make?
Research Question
Research one of the following aspects of climate change
in the your territory:
- reasons for accelerated temperature change in the
north
- impacts on the land
- impacts on plants and animals
- steps your region is taking to reduce fossil
fuel dependency
Note: Some of the other Backgrounders provide
a good starting point for research on these
questions.
Backgrounder #2: The Greenhouse Effect
Content Questions
- How does the natural greenhouse effect keep the earth’s
temperature at a liveable level?
- How did the industrial revolution disturb the carbon dioxide
balance and increase the earth’s temperature?
- Why have temperatures increased more in the north than in other
parts of the world?
Reflective Question
People have known about the dangers of too many GHGs in the atmosphere
since 1957, yet GHG emissions have continued to rise. North America – both
the US and Canada – are among the worst GHG emitters. Why do you
think people are unwilling to reduce their GHGs? What will it take to
bring about real GHG reductions?
Research Question
What is the role of the oil companies in encouraging governments to keep
on using fossil fuels, and emitting GHGs? Different oil companies have
taken different approaches to fossil fuels and “clean” fuel
sources. If you go to the homepages of different companies, and do a
search on their names, you may find out some interesting things. (For
example, what companies are mixing biofuel with fossil-fuel gas, and
which are putting money into clean alternative energy.) Also, try going
into the websites of environmental groups to see what they are saying
about oil companies. Decide which oil company you think concerned citizens
should support, and why.
Backgrounder #3: Greenhouse Gases (GHGs)
Content Questions
- How do greenhouse gases affect the earth’s temperature?
- What are the “big four” greenhouse gases? What are
the main sources of each of these four?
- How do carbon sinks work? What are the major types of carbon
sinks?
Reflective Question
Transportation is one of the main “bad guys” in the GHG emission
picture. Private cars (often carrying just one passenger), trucks (transporting
food and other goods from long distances) and airplanes (carrying both
goods and people) are responsible for a large amount of GHG emissions.
In the north, where population is dispersed and the growing season is
short, people are especially reliant on these methods of transportation.
Spend some time thinking about how northerners could realistically cut
back on transport-related GHG emissions. What would you and your family
be willing to do in this area?
Research Question
Research the role of carbon sinks in reducing climate change. Where are
the world’s largest carbon sinks? What will happen if they disappear?
Backgrounder #4: Weather and Climate
Content Questions
- What’s the difference between weather and climate?
- How does heat from the sun get trapped, then moved around the
earth?
- How might increased temperatures change the water levels and
precipitation patterns in the north?
- What’s an ecosystem? How could northern ecosystems be affected
by climate change?
Reflective Question
Northern aboriginal cultures have been influenced by climate. If the
northern climate changes, how might traditional cultures be affected?
Research Question
How has the climate changed in your region over the past 30 years?
Ask an elder what changes he or she has noticed. Contact Environment
Canada
or your local weather office to compare local knowledge with
scientific weather measurements.
Backgrounder #5: How do we know?
Content Questions
- How do paleoclimatologists find out information about past climates?
- How can ice give us information about climates long ago?
- What is the IPCC, and why is it important?
- What kinds of climate change research are happening in the Arctic?
- Why is local knowledge important to climate change researchers?
Reflective Question
Often we think of research scientists as people in white coats, working
in distant laboratories. But northern scientists studying
climate change are collecting local knowledge, and small communities
are getting involved
in collecting information. Can you see any way that you,
your
school, and your community could become involved in local monitoring,
either
now or in the future?
Research Question
What climate change research is going on near you? Search
the northern websites listed in the Resources section
to see what
research projects
you can find.
Backgrounder #6: A Changing Land
Content Questions
- What major changes in northern land can you expect to see if
climate change increases?
- What changes will climate change bring to the tundra?
- What effect will climate change have on tundra plants and animals?
- How will boreal forests be affected by climate change?
Reflective Question
How might changes in the land – permafrost and wetlands, for instance – affect
your community, your lifestyle, and your culture, hunting and fishing?
Research Question
How are the land and the vegetation in your region changing?
What do northern scientists predict may happen to the lands and the vegetation
of the north? Check out the list of websites on at the end of Backgrounder
#6. Another useful website is: Northern climate Exchange – http://www.taiga.net/nce/.
Backgrounder #7: The Changing World of Water & Ice
Content Questions
- What changes have occurred to Arctic ice since the 1950s?
- Explain the “positive feedback loop” in Arctic ice
melting – or,
in other words, when ice melts (creating patches of open water), why
does the remaining ice melt even faster?
- What’s happening to sea levels? What effects will changing
sea levels have on coastal communities in the north?
- Explain what effect climate change is having on glaciers. What
impact might fresh water from melting glaciers have on the oceans,
and marine
life?
Reflective Questions (choose one)
- How could thinning ice and earlier break-up affect the lifestyle
of people in your community?
- Some people are happy about the possibility of sending ships
through the Arctic Ocean in the summer months. How do you
feel about it,
and why?
Research Question
Research what is happening to the Arctic glaciers and sea ice.
Backgrounder #8: Impacts on Northern Wildlife
Content Questions
- In what ways will caribou be affected by climate change?
- What animals are moving north? Why are they moving?
- What impact could climate change have on small mammals?
Reflective Question
How would it affect you if the caribou herds diminished? How would
it affect the lifestyles of many northern people?
Research Questions
- What are scientists saying about how climate change could
affect the Porcupine Caribou herd and other northern
caribou herds? A
good site
to start looking is on the Taiga site, at http://www.taiga.net/top/caribou.html.
- Choose a northern species of animal in your region
and research it. What are the habitat and the habits
of the
animal? Think
about the food
they eat, what preys on them, what climate they
like, what type of land they live in. Find out how this animal
is
likely to be
affected
by climate
change.
Backgrounder #9: Impacts on Fish and Fowl
Content Questions
- It seems that some fish may be able to adapt to climate change
better than others. Explain which fish will be the winners, and which
the
losers, and why.
- What problems could climate change cause for salmon?
- How has warmer northern climate affected duck populations?
Reflective Question
How would it affect you if Arctic Char populations decline due to
warming waters? How would it affect other animals? How might
it impact the
lifestyles of many northern people?
Research Question
What is happening to local fish populations? Ask an elder
or your local biologist what is happening, and what they
predict
could
happen if
waters warm.
Backgrounder #10 – Impacts on Northern Marine Life
Content Questions
- Polar bears are among the animals most affected by climate change.
Explain how Hudson Bay polar bears are affected by earlier spring
break-up and by changing snowfall patterns.
- What impacts could climate change have on: seals, walruses, whales,
and sea birds?
- What could happen to the marine food chain if algae or codfish
were reduced because of climate change?
Reflective Question
Hudson Bay polar bears are already being impacted by climate
change. There are many concerns about the survival of polar
bears across
the Arctic. Many websites tell about the polar bears and
what is happening
to them. Why do you suppose the polar bear is such an important
symbol of the north?
Research Question
Research the impacts of climate change on polar bears across
the north. The list of websites in Backgrounder #10 is
a good place
to start.
Backgrounder #11: Northern Community Impacts and Adaptations
Content Questions
- How do quickly changing patterns of permafrost, ice and snow
make it difficult for northerners, especially those who live traditional
lifestyles?
- What are the pros of climate change for northern communities?
What are the cons?
- What are some of the adaptations that northern communities are
already making in response to climate change?
Reflective Questions (choose one)
- When you weigh the pros and the cons of climate change, do you
feel the total result for you and your community will be pro or con?
- How well do you think your community will be able to adapt to
the changes caused by climate change? How could they start to prepare
for
the expected changes?
Research Questions
- How is climate change currently impacting your region? Two good
websites to start your research are:
- What plans does your territorial government have in place for
responding to climate change? Contact government officials and elected
representatives
to find out.
Backgrounder #12: Global impacts of Climate Change
Content Questions
- Identify and explain the different ways people around the world
will be affected by climate change.
- In 1998, more than 25 million people had to leave their homes
because of floods, drought, deforestation or other environmental problems.
Explain
how this is probably linked to climate change.
- What difference would a few more bugs make? Explain how the northern
movement of southern insects and parasites could make a big difference
to people in Canada.
- How might the world’s oceans and marine life be affected
by climate change?
Reflective Questions (choose one)
- Although the rich industrialized countries are the ones that
create the most GHGs, people in the poor, southern countries are the
ones
who will suffer the greatest impacts of climate change. Put yourself
in the
role of a South Pacific islander, whose island home may disappear
under the rising sea levels, and imagine what you would say to
a Canadian
with high GHG emissions?
- Climate change has the heaviest impact on traditional peoples.
Can you explain why you think this statement is true or false?
Research Question
Choose one country in the developing world. Research the predicted
effects of climate change on that country.
Backgrounder #13: Renewable Energy Opportunities
Content Questions
- What is non-renewable energy? Renewable energy?
- List and describe five different types of renewable energy.
- What are the barriers to replacing non-renewable energy sources
with renewable ones?
Reflective Question
What’s stopping us from making the switch to non-renewable energies?
Part of it may be cost, but what other reasons can you can think of?
Research Questions
- What renewable energies are being used or planned for future
use in your territory?
- How would you go about adding a renewable energy component to
your school? Good places to start are: the lesson entitled
Renewable Energy
And Your School, and the Re-Energy website (http://re-energy.ca/),
which tells you how to build renewable energy projects.
Backgrounder #14: Helping in Your Own Way
Content Questions
- When we’re considering how to reduce GHG emissions, what
are the main areas to consider?
- What are some ways of reducing the GHGs we emit by driving?
- How can you save energy in your home?
- What does the stuff you buy have to do with GHG emissions?
Reflective Questions (choose one)
- The Government of Canada is challenging every Canadian to see
if they can cut back their production of GHGs by one tonne (that’s
20%) by 2008-2012. Do you think you are up for it? What things could
you change
without too much difficulty?
- In Canada, individuals are responsible for 25% of GHG emissions.
But what about the big industries that produce much of the remaining
75%?
How could you, as an individual, encourage companies to reduce their
GHG emissions?
Research Questions
- Research the energy use in your household. Look at your energy
bills. Do a household audit (see the lesson entitled Auditing
the Energy-Guzzlers in Your Home). With your family, set a target of energy reduction.
Keep
track of your energy bills to see how well you’re doing.
- Methane emitted from landfill dumps is one of the runaway GHG
gases. Research what your community is doing to reduce landfill dumping.
Backgrounder #15: What Schools can do!
Content Questions
- List the things schools can do to reduce their GHG emissions.
- Why is it important to keep lights off and heat in?
- What does reducing consumption (the amount of things you use)
have to do with reducing GHG emissions?
- How can schools encourage greener transportation to and
from school?
Reflective Question
What ideas can you think of to help your school reduce
its GHG emissions? Try to be as realistic as possible,
and to
think of
ways to motivate
students and teachers to make changes.
Research Question
Research what other schools are doing to reduce their
GHG emissions. Put together a set of recommendations
for your
school. (Refer
to the websites listed at the end of Backgrounder
#15, and also the
website
list in Resources.)
Backgrounder #16: Climate Change Agreements… and Disagreements
Content Questions
- Explain the Kyoto Protocol: What is its goal? What challenges
are there to getting it ratified?
- What are ‘emission credits,’ and why are they controversial?
- What arguments have some people have made against ratifying the
Kyoto Protocol?
Reflective Question
One of the arguments that some Canadian businesses have made against
ratifying the Kyoto Protocol is that, because the U.S. has refused to
ratify the Protocol, Canada should refuse, too. These business people
say that ratifying Kyoto will make our businesses less competitive because
they will have to reduce their GHG emissions but American businesses
won’t. What do you think of this argument? Should Canada have ratified
the Kyoto Protocol (as we did), even though the Americans didn’t?
Why or why not?
Research Question
Research the Kyoto Protocol. Who has ratified? Who hasn’t? What
are some of the arguments that have been used for and against? (One interesting
idea is the job opportunities that Kyoto may create. Go to the Suzuki
Foundation Site: http://www.davidsuzuki.org/Climate_Change/Kyoto/, and
click on the link “Kyoto Economics” link at the bottom of
the page.)
Backgrounder #17: Governments and Businesses: Walking the Talk
Content Questions
- List as many examples as you can of governments taking action
to reduce GHGs.
- What are some ways that territorial governments can use the tax
system to encourage GHG reduction?
- What can municipal governments do to reduce GHG emissions?
- What could industries do to reduce their GHG emissions? What
are some cutting-edge industries doing?
Reflective Question
Sometimes industries need a little encouragement to bring about changes
that would lead to a reduction of their GHG emissions. How can you as
an individual encourage industries to become greener? How can governments
encourage industries to become greener?
Research Question Research what’s planned in your territory to reduce GHG emissions.
Get a copy of the Action Plan for your territory. Find out what parts
of it are being implemented, and what parts are not. (Note: If there
is not action plan, find out why not.) |
