Climate Change in the Arctic: Economic Boon or
Environmental Crisis?
Introduction
A recent article published in the New York Times, Race Is On as Ice Melt Reveals Arctic Treasure,
highlights the possible economic boon as well as a possible environmental crisis due to the changes in
the extent of sea ice in Arctic Ocean. This change is due to Earth’s increasing temperature. Over the past
two centuries, Earth’s mean annual temperature has increased 1°F (0.6°C). In the Arctic region, the
mean annual temperature has changed more drastically—5 to 7°F (3 to 4°C).
Issue
Although there are many issues related to the decrease of Arctic sea ice, such as Arctic oil exploration
and mining, this investigation will address the following question:
If the Arctic shipping routes are viable, should they be exploited?
The possibility of an ice-free passage through the Arctic Ocean has been explored for centuries (e.g. the
Northwest Passage). A route, however, has been proven elusive due to the extensive coverage of the
Arctic sea ice. Due to the decrease of this sea ice, governments and shipping companies, among others,
wonder if Arctic shipping routes (e.g. The Northwest Passage, The Northern Sea Route) are possible.
Although these routes might be a boon for exporters, others, however, wonder if these routes should be
even considered due to the environmental impacts such as increased pollution.

Part 1: Sea ice, shipping, and seasons
The goal for Part 1 is to describe changes of Arctic sea ice and to assess current shipping routes with the
proposed ones (e.g. the Northwest Passage) in the Arctic Ocean. As a reminder the research question
for this activity is: If the Arctic shipping routes are viable, should they be exploited?
To address the above goal, first, watch the video (see link below) that introduces the issue of global
climate change and Arctic shipping. Second, analyze current trends in the extent of Arctic sea ice
seasonally and over the past several decades and then describe how these changes might affect
shipping. Third, describe present-day shipping routes and then compare them to the possible ones in
the Arctic. Fourth, select three existing shipping routes that would benefit the most if the Arctic was
open to shipping. You can record the above information you collect in the graphic organizers that follow.
After you complete this section, you will be expected to summarize what you learned with the class.
1. According to CBC, or Canadian Broadcasting Corporation, a Canadian scientist claims the Arctic
Ocean will be open for regular commercial shipping within the next five to ten years, but
changing ice conditions could also bring new hazards to ships. Watch the CBC news video titled
“Arctic Ocean Could be Open for Shipping in 5-10 Years” and complete Table 1 below.

2. The coverage of Arctic sea ice changes seasonally and from year to year. Go to the Arctic Sea Ice
and News and Analysis (from the National Snow & Ice Data Center) and select three sets of data
that describes the changes in Arctic sea ice seasonally and over the past several decades. Then,
hypothesize how these changes in Arctic sea ice might affect global shipping. Please use Table 2
to complete this task.

3. Next, compare current major shipping routes and passages with the possible ones in the Arctic.
First, read the selected chapters from The Geography of Transport Systems website (see Table
3). Then, describe each strategic passage and shipping route, both current and the ones
proposed in the Arctic. Record this in Table 4. Also, please print the “Main Maritime Shipping
Routes” and the “Polar Shipping Routes” maps, you will need them for future reference.

Part 2: Global Climate Change and Arctic Sea Ice
The goal for Part 2 is to draw evidence-based conclusions related to global climate change and Arctic sea
ice from multiple lines of evidence, and to make connections between these conclusions with the
Intergovernmental Panel on Climate Change (IPCC) report on climate change. To meet the above goal,
you will first analyze multiple sets of data that examines the relationship between atmospheric carbon
dioxide and global temperature. Second, you will analyze multiple sets of data in order to examine the
effects of changing global temperature on Arctic sea ice. Third, you will share your findings with your
classmates. Finally, you will summarize the connections between your findings and the IPCC’s findings
on climate change and sea ice.
Investigation 1: Carbon Dioxide and Global Temperature

you learned below.
Making Connections:
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the
assessment of climate change. This organization publishes reports on climate change. To learn more
about this organization, please go to their website at http://www.ipcc.ch/index.htm.
Download the latest report at:
2007 IPCC Summary Report: http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/ar4-wg1-spm.pdf
Wrap-up/Conclusions
What is correlation among global surface temperatures, carbon dioxide, and coverage of Arctic sea ice
(see Investigation 1 and Investigation 2)? How does the 2007 IPCC report align with the research
findings?
Part 3: Forecasting Global Climate Change—using models
The goal for Part 3 of this activity is to analyze climate system models that forecast changes of global
temperature and then predict the extent of Arctic sea ice associated with the proposed shipping routes.
To meet this goal, analyze the climate system forecast models in the Arctic region. Then, predict the
extent of the Arctic sea ice for the upcoming decades. Finally, assess if shipping routes are plausible in
the Arctic based on these climate and sea ice predictions. Follow the guidelines below to complete this
task.
Making Predictions
1. Reanalyze the changes in Arctic Sea ice from 1979 to present again (from Part 1). Describe how
the extent of the Arctic sea ice changed. How does this correlate with air temperature changes?
Record this analysis in Table 9 below. This analysis is the baseline to predict the extent of the
Arctic sea ice will change using various forecast models (see Table 8).

2. Analyze the climate prediction models for the entire Arctic region. Use the NCAR Community
Climate System Model in Table 8. Examine and record your analysis for each of the following
"Global Air Temperature" models: a) all scenarios, b) middle of the road, c) best case, and d)
worst case. Record the analysis of these forecast models in Table 9.
NOTE: Please be sure to analyze the data both spatially (e.g. the Arctic Region) as well as
temporally (e.g. over the time period of the prediction models).
3. In Table 9, predict the extent of sea ice coverage spatially and over time based on the analysis.
4. In Table 9, justify the extent and duration of Arctic sea ice that may “open” the Northwest
Passage and the Northern Sea Route.
