3. Kinds of climate modification
• Inadvertent
• Advertent
– “We are inadvertently changing the
climate, so why not advertently try to
counterbalance it?” (Mike MacCracken)
• Quick or Creeping onset
4. Societal interactions with Climate
(3 competing perspectives)
Society… dominates Climate
is subordinate to Climate
in harmony with climate
Climate change must be placed in context of other important stresses,
e.g., land use changes & population growth.
Climate change may exacerbate or ameliorate existing stresses
Threats to subsistence livelihoods are already being exacerbated by
multiple climate-related factors, e.g.,
reduced or displaced populations of marine mammals,
seabirds and other wildlife
reduction and thinning of sea ice, making hunting more
difficult and dangerous
5. Geo-Schemes proposed to stop Global
Warming
• Carbon sequestration
• Iron particles in the
ocean
• Global scale tree
planting
• Go nuclear
• Go renewable energy

6. The systemic nature of climate change impacts
is an added challenge
Health Impacts
Weather-related Mortality
Infectious Diseases
Air Quality-Respiratory Illnesses
Agriculture Impacts
Climate Changes
Temperature
Precipitation
Sea Level Rise
Crop yields
Irrigation demands
Forest Impacts
Change in forest composition
Shift geographic range of forests
Forest Health and Productivity
Water Resource Impacts
Changes in water supply
Water quality
Increased competition for water
Impacts on Coastal Areas
Erosion of beaches
Inundate coastal lands
Costs to defend coastal communities
Species and Natural Areas
Cultural Resources
Shift in ecological zones
Loss of habitat and species

8. We can plan ahead…. or we can react
Wildlife can only react
But humans can anticipate

10. Some thoughts
about climate engineering
• Societies try to make marginal lands productive,
while they degrade productive lands.
• Technology is neutral. How we use it determines
whether it has positive or negative impacts.
• Societies need to move from an environmental
ethic and modus operandi of dominance to that of
harmony.

but Nature is now turning against him and he finds himself
caught in a trap.”
