Transcript of Climate Engineering: The EARTH's Doctor.
Our War against climate: geo-engineering climate & weather
and the paradox of second best
Sandia Lab Program logo
A reversal of fortune or
NATURE strikes back !!
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
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
Geo-Schemes proposed to stop Global Warming
• Carbon sequestration• Iron particles in the
ocean• Global scale tree planting• Go nuclear• Go renewable energy

Agriculture ImpactsCrop yieldsIrrigation demands
Water Resource ImpactsChanges in water supplyWater qualityIncreased competition for water
Impacts on Coastal AreasErosion of beachesInundate coastal landsCosts to defend coastal communities
Forest ImpactsChange in forest compositionShift geographic range of forestsForest Health and Productivity
Species and Natural AreasShift in ecological zonesLoss of habitat and species
The systemic nature of climate change impactsis an added challenge
Climate Changes

Cultural Resources
Wildlife can only react
But humans can anticipate
We can plan ahead…. or we can react
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.
“Man believed he could dominate Nature and bend it to his will, but Nature is now turning against him and he finds himself caught in a trap.”
