OVERVIEW
Project Background
Changing climatic conditions
impact environmental, social
and economic conditions in
National Park System areas.
Alaska park managers need to
understand changes in order to
more effectively manage various
ecosystems and human uses.
NPS and SNAP collaborate to help
managers, personnel, and key stakeholders develop plausible climate
change scenarios for Alaska NPS areas.

The science of climate change
 Unequivocal scientific evidence that our
planet is warming
 How this warming will affect climate
systems around the globe is an
enormously complex question
 Uncertainty and variability are inevitable
 Climate change presents significant risks
to natural and cultural resources
 Understanding how to address
uncertainty is an important part of
climate change planning

Climate Drivers, or
“Scenario Drivers Based on Climate”
Scenarios planners
look at the general
and specific
changes expected
in each climate
driver, as well as
the size and
patterns of the
expected change.
 Temperature
 Precipitation
 Relative humidity
 Wind speed
 Pacific Decadal Oscillation (PDO)
 Extreme weather events
 Sea ice
 Permafrost
 Snow
 Freeze-up date
 Sea level
 Water availability
Atmosphere Climate Effects
Selected and ranked by participants
Increased carbon storage where forests spread; decreased where
Greenhouse gases drought causes loss of forest or where fire and permafrost release
methane and CO2
ATMOSPHERE
Air temperature
Precipitation
Air temperature increases ~1°F per decade; greatest change in the
north and in winter.
Average annual precipitation increases. Relative amounts of snow, ice
or rain change.
Many areas experience drying conditions despite increased
precipitation.
More freezing rain events affect foraging success for wildlife, travel
safety, etc.
Lightning and lightning-ignited fires continue to increase.
Storms
Storm and wave impacts increase in northern Alaska where land-fast
sea ice forms later.
Air quality
More smoke from longer and more intense fire seasons.
Contaminants
Increased contaminants and shifting contaminant distribution.
[See “edited annotated effects SW parks”]
Cryosphere Climate Effects
Selected and ranked by participants
Later onset of freeze-up and snowfall + earlier spring snowmelt and break-up.
Snow/ice
Arctic snow cover declines with higher air temperatures and earlier spring thaw.
Lack of snow cover leads to deeper freezing of water in the ground or rivers.
CRYOSPHERE
Cultural resources are exposed as snow and ice patches melt and recede.
Glaciers
Most glaciers diminish as warming continues, though a few are still advancing.
Glacial outwash affects aquatic productivity and forms deposits in shallow water.
Glacial lakes fail more frequently, creating risk of flash floods and debris flows.
Surging glaciers could block rivers and fjords, resulting in severe flooding.
Less sea ice complicates travel, impacts ecosystems, and adds energy to storm
surges.
Sea ice
Seasonal reductions in sea ice increase the risk of spills contaminating coastal
resources.
Reduced winter transportation affects opportunities for travel and subsistence.
Ice roads
Mercury & other pollutants are released into aquatic environments as permafrost
Permafrost
thaws.
[See “edited annotated effects SW parks”]
Hydrosphere Climate Effects
Selected and ranked by participants
st
Sea level
Global average sea level is predicted to rise 1-6 feet by the end of the 21 Century.
Increased storm surges and permafrost erosion compound effects of change in sea
level.
Some coastal villages rapidly lose ground from storms, erosion and subsidence.
HYDROSPHERE
Increasing sea surface temperature affects fish, seabird, and wildlife populations.
Marine
Falling global phytoplankton could reduce ocean productivity and CO2 sequestration.
Freshwater influx from thawing glaciers dilutes marine waters, stressing animals.
Toxic marine algae & shellfish poisoning attributed to changes in water conditions.
Ocean acidification affects food sources of fish, marine mammals & birds in the Arctic.
Estuarine
Coastal erosion and sea level rise increase the frequency of saltwater flooding.
Some shallow water areas convert to terrestrial ecosystems with post-glacial rebound.
Freshwater
Stream flows from melting glaciers increase and then decrease over time.
Ponds shrink as ground ice thaws or thermokarst drainage occurs in permafrost areas.
Groundwater Groundwater supplies dependent on seasonal glacial recharge become less predictable.
[See “edited annotated effects SW parks”]
Climate Effects, as selected and ranked by participants
LITHOSPHERE
Ground
level
Ground level rises in recently de-glaciated areas because of isostatic rebound.
LITHOSPHERE
More roads and infrastructure fail or require repairs due to permafrost thaw.
Ground
stability
Landslides and mud flows increase on steep slopes. Rapid glacial retreat and
permafrost thaw leave steep and unstable slopes in valleys and fjords.
Earthquake activity increases in recently deglaciated areas due to isostatic
rebound.
Large and small tsunamis could result from collapse of unstable slopes in fjords.
Coastal erosion claims both natural and cultural resources and constructed assets.
Burials and other remains are exposed as cultural sites thaw and erode.
Soil
Soil moisture declines due to rising soil temperature, thawing permafrost, and
drainage.
[See “edited annotated effects SW parks”]
Biosphere Climate Effects – 1 of 4
Selected and ranked by participants
Average number of frost-free days for the Arctic could increase between 20 and 40
days by 2100.
Vegetation Increased agricultural production in Alaska because of longer growing season.
Potential large-scale shift of tundra to shrubs, to conifers, to deciduous forests or grass.
BIOSPHERE
Atypical outbreaks of pests and diseases affect native species and increase fire hazards.
Invasive exotic plant species and native species from other areas expand their ranges.
Forests
Black spruce may expand with warming – or contract as permafrost soils thaw and fires
increase.
Mature forests and “old growth” decline because of drought, insects, disease, and fire.
Mature yellow cedars decline across southeast Alaska, possibly due to lack of insulating
snow.
Fire
Models show a warmer climate leads to larger, more frequent and intense fires.
Wildland fire hazards increase, affecting communities and isolated property owners.
Fire-related landcover and soil changes result in vegetation shifts, permafrost thaw, etc.
[See “edited annotated effects SW parks”]
Biosphere Climate Effects – 2 of 4
Selected and ranked by participants
Changes to terrestrial and aquatic species occur as ranges shift, contract, expand.
Wildlife
Animals and plants will expand into landscapes vacated by glacial ice.
BIOSPHERE
Migratory routes and destinations will change (e.g., wetlands, open tundra, snow
patches).
Arctic and alpine birds’ breeding habitats reduced as trees and shrubs encroach on
tundra.
Birds
Waterfowl shifts occur as coastal ponds become more salty.
Productivity of nesting shorebirds may increase if schedules change to coincide w/
insects.
Predation on ground nesting birds could increase if prey (lemming) abundance
declines.
Coastal seabirds (e.g. Ivory Gull and Aleutian Tern) are vulnerable to climate change.
Population cycles of birds and their prey could be out of sync due to higher
temperatures.
Marine
Mammals
Arctic marine mammals (e.g. seals, walrus, whales) are affected by sea ice decline.
Less sound absorption (ocean acidification) affects marine mammals that rely on
echolocation.
[See “edited annotated effects SW parks”]
Biosphere Climate Effects – 3 of 4
Selected and ranked by participants
Caribou/
Reindeer
BIOSPHERE
Moose
Caribou and reindeer health are affected by changes in weather, forage, and insects and
pests.
Earlier green-up could improve caribou calf survival because of more available forage.
Caribou may suffer heavy losses if rain events prevent successful feeding during cold
weather.
Shifts in forests could mean less habitat for caribou, but more habitat for moose.
Climate change could hinder moose calf birth success and moose calf survival.
Fire may create new burrowing habitat and forage growth to help vole populations.
Small
Mammals Less snow cover = increased predation & cold stress for subnivian species.
Commercial fisheries affected by changes to ocean communities in the Bering Sea.
Some marine plant and animal populations may decline with ocean acidification.
Fisheries
New stream habitats become available for fish and wildlife as glaciers decline.
Some salmon waters may become unsuitable for migration, spawning and incubation.
Fish habitats in permafrost areas are degraded by slumps and sediment input into rivers.
Invertebrates
Ice worm populations decline locally as glacier habitats melt.
Exotic pests expand from warmer areas, endemic pests expand as host species are
stressed.
[See “edited annotated effects SW parks”]
Biosphere Climate Effects – 4 of 4
Selected and ranked by participants
Altered animal migration patterns make subsistence hunting more challenging.
BIOSPHERE
Subsistence
Sea ice changes make hunting for marine mammals less predictable & more
dangerous.
Managing new species and intensified management of native species may be
needed.
Tourism
Longer summer seasons and more cruise ships in the Bering Strait could
increase tourism.
Hazards
Safety hazards related to climate change, e.g. thin ice, flooding, changing fire
regimes, etc.
TEK
Uses of traditional ecological knowledge become less predictive and less
reliable.
Development
More natural resource development in Alaska with increasing global demand.
More developmental pressures, e.g. opening of Northwest Passage,
community resettlement, etc.

A Basic GBN Scenario Creation Process
This diagram describes
the 5 key steps required
in any scenario
planning process
What is the strategic
issue or decision that
we wish to address?
What critical forces
will affect the
future of
our issue?
How do we combine and
synthesize these forces to
create a small number of
alternative stories?
Global Business Network (GBN)
As new
information
unfolds, which
scenarios seem
most valid?
Does this affect
our decisions
and actions?
What are the implications
of these scenarios for our
strategic issue, and what
actions should we take
in light of them?

Scenario Creation Process
Step One: Orient
Strategic issue or decision:
How can NPS managers best
preserve the natural and cultural
resources and values within their
jurisdiction in the face of climate
change?
Kenai Fjords National Park
To address this challenge, we need to explore a broader question:
How will climate change effects
impact the landscapes within
NPS management units over the
next 50 to 100 years?

Step 4: Choosing Response Strategies
Robust responses are
common no-regrets actions,
but they are not the only
possibility.
In some cases, it may make
sense to hedge bets to avoid
an occurrence that appears
in only one or two scenarios,
or to set up core and satellite
responses to deal with
variability among scenarios.
