T changes for 2x CO2The two globes summarize computer simulations to compare the warming expected under a doubling of CO2
from the pre-industrial level with the warming expected from a quadrupling.
Note that N hemisphere mid-continent average warming in the 4xCO2
world is 15-25°F!
This is a roasted world.

The multiple aims of energy strategy
ECONOMIC AIMS
• provide reliable heat, fuel, & electricity for basic needs & economic growth
• limit consumer costs of energy
• limit cost & vulnerability from energy imports
The multiple aims (continued)
ENVIRONMENTAL AIMS
• improve urban and regional air quality
• avoid nuclear-reactor accidents & waste-mgmt mishaps
• limit impacts of energy development on fragile ecosystems
• limit energy-supply impacts on global climate
The multiple aims (concluded)
NATIONAL- & INTERNATIONAL-SECURITY AIMS
• minimize dangers of conflict over oil & gas resources
• avoid spread of nuclear weapons from nuclear energy
• reduce vulnerability of energy systems to terrorist attack
• avoid energy blunders that perpetuate or create deprivation
Why energy strategy is difficult
• The aims are often in tension with each other.
• There’s no technological silver bullet.

Under continuation of BAU
• World use of primary energy reaches 2.5 times the 2000 level by 2050 and 4 times the 2000 level by 2100.
• World electricity generation reaches 5 times the 2000 level by 2100.
• World CO2 emissions reach 3 times the 2000 level by 2100.
Is there a problem with this?
The problem is not
“running out”
of energy
Some mid-range estimates of world energy resources. Units are terawatt- years (TWy). Total world energy use is ~15 TWy/year.

This is under 1% of projected GWP and only about 5% of projected
world investment. (But it could reach 15% of investment in developing
countries.)
International Energy Agency 2005
• cost minimization vs. modernization, increased robustness & reliability, environmental improvements, energy security
• increased domestic fossil-fuel production (for security) vs. protection of fragile ecosystems
• increased nuclear-energy production (for greenhouse- gas abatement) vs. reducing risks of nuclear accidents & terrorism
Real problem: tensions among energy- policy aims
Real problem: No “silver bullet”
( No known energy option is free of question marks)
• conventional oil & gas… not enough resources?• coal, tar sands, oil shale… not enough atmosphere?• biomass… not enough land?• wind & hydro… not enough good sites?• photovoltaics… too expensive?• nuclear fission… too unforgiving?• nuclear fusion… too difficult?• hydrogen… energy to make it?
means to store it? • end-use efficiency… not enough smart end-
users?
• best compromise among competing economic, environmental, & security objectives, given the resources & technologies available at the time;
• to promote technological advances that reduce limitations of existing energy options, open new options, and reduce the tensions among energy- policy objectives.
The primary tasks of energy policy are thus…
• many of the goals relate to public goods (like national security) & externalities (like pollution) that are not priced in markets unless policies achieve this;
• markets often also need other kinds of help to avoid “market failures” from abuse of monopoly power, lack of information, perverse incentives, short time horizons, etc.
These ends cannot be achieved by markets alone, because...
The two biggest energy challenges are…
• Reducing the dangers from oil dependence
• Providing the affordable energy needed to create & sustain prosperity everywhere without wrecking the global climate with carbon dioxide emitted by fossil-fuel burning.
Let’s look at these in more detail….
The oil challenge: supply & security
• USA in 2005 used 21 million barrels per day of oil, importing 60% of it.
• Forecasts show US oil use rising to 28 Mb/d by 2030, with all of the increase coming from imports.
• World used 81 Mb/d in 2005, 50% of it traded internationally.
• Consumption forecasted to rise from 81 Mb/d in 2005 to 120 Mb/d in 2030.
• China’s imports by 2030 expected to reach 12 Mb/d.• It remains true that most of the world’s known &
suspected oil resources are in the Middle East.
Dangers of oil dependence
import dependence worsening balance of payments
enrichment of oil-exporting regimes that may use the money to export terror & import nuclear weapons
total oil dependence economic vulnerability to price shocks
increased incentive for military actionto maintain access
reduced freedom of action in foreignpolicy and counter-terrorism

Developing Asia’s dependence on the Persian Gulf is already bigger than North America’s and is expected to grow much faster.

The oil challenge
ENVIRONMENT• Most oil is used in transport vehicles, and these are
the largest sources of NOx and hydrocarbon air pollution.
• The number of cars in the world is soaring, producing increased congestion and even more pollution.
• Combustion of petroleum fuels accounts for about 40% of CO2 emissions from energy – same as coal – and this is expected to continue.

The climate-change challenge
• Global climate is changing rapidly and humans are responsible for most of the change.
• CO2 emissions are the largest driver & 75-85% of these come from combustion of fossil fuels (the rest from deforestation).
• Fossil CO2 emissions are immense (27 million tonnes/yr in 2005) & difficult to capture & store.
• The world’s 80%-fossil-fuel-dependent energy system represents a huge capital investment that takes 30-40 years to turn over.
• Avoiding biggest risks requires sharply reducing CO2 /energy ratio starting immediately.
How much mitigation?
•
Under continuation of “business as usual”
(BAU), global
average surface temperature (∆Tavg
) is likely to reach almost 2°C by 2050, 3°C by 2100, and 4-5°C by 2150.
•
The best current science indicates that…
–
∆Tavg
~ 1.5°C could
mean the end of coral reefs;
–
∆Tavg
~ 2°C
could
mean catastrophic melting of
Greenland & Antarctic ice, producing rates of sea-level rise that could reach 3-4 meters per century;
–
∆Tavg
~ 2.5°C
is likely
to sharply reduce crop yields
worldwide.
Suitable CO2
target?
•
Thus stopping at 2x pre-industrial CO2
(550 ppmv, corresponding to ~3°C), once thought a reason-able target by many) may not be good enough.
•
Many analysts & groups now conclude that prudence requires aiming not to exceed 2°C (450 ppmv
which many analysts think is
VERY tough).

COAL IN THE U.S.?Cannot build conventional coal and meet climate targets
• Magnitude• 125 proposed plants,
500 million tons CO2
• Challenge• Stop old coal; shift
to cleaner options• Means• Education,
economic analysis, health analysis, media
•IPCC 1990:
The observed increase [in temperatures] could be largely due to natural variability; alternatively this variability andother man-made factors could have offset a still larger man-made greenhouse warming.
•IPCC 1995:
The balance of evidence suggests a discernible humaninfluence on global climate.
•IPCC 2001:
There is new and stronger evidence that most of the warming observed over the last 50 years is due to human activities.
•IPCC 2007: Most of the observed increase in global temperatures since the mid-20th century is very likely
(90%) due to the observed increase in anthropogenic greenhouse gas concentrations. Discernible human influences include ocean warming, continental-
average temperatures, temperature extremes and wind patterns.
Increasing Confidence in the Science
Key variables have beentracking or exceedingIPCC projections
IPCC projections published in the 2001 assessment were based on data to 1990.
Observations since 1990 havetracked the projections for CO2, have been near the high side of projected rangesfor temperature, and havebeen at the extreme high side of the projections for sea-level rise.
Rahmstorf
et al., Science Express, February 2007
2005 was the hottest year on record; the 13 hottest all occurred since 1990, 23 out of the 24 hottest since 1980.

Facing the challenge
••
Mitigation & adaptationMitigation & adaptation
are both
essential.
•
Human-caused climate change is already occurring.
•
Adaptation is already taking place without forethought & must be expanded—we need to anticipate future changes and develop planning, management, and technology solutions.
•
But adaptation becomes costlier & less effective as the magnitude of climate changes grows.
•
The greater the amount of mitigation that can be achieved at affordable cost, the smaller the burdens placed on adaptation.
•
Can ecosystems adapt? – Rates of change expected faster than observed
in the record of the last 10,000 years.
– Ecosystems cannot move “intact”.
– Interactions with other environmental stresses not considered.
•
Almost no research specifically done on ecological or societal adaptation– About 1-5% of the global change research
budget spent on adaptation
•
“Tipping points”
may be exceeded even at 2 degrees C and may be “dangerous”
Meanwhile, climate-change science
is actually being cut! Budget authority in constant FY2007$

Millennium Development Goals
1. Eradicate Extreme Poverty and Hunger--Halve, between 1990 and 2015, the
proportion of people living on less than $1/day and the proportion of people suffering from hunger.
2. Achieve Universal Primary Education
3. Promote Gender Equality & Empower Women
4. Reduce Child Mortality--Reduce by 2/3, between 1990 and 2015, the under-5 mortality
rate.
5. Improve Maternal Health--Reduce by 3/4, between 1990 and 2015, the maternal
mortality rate
6. Combat HIV/AIDS, malaria and other diseases--By 2015 have halted
and begun to reverse the spread of HIV aids and the incidence of malaria and other major diseases.
7. Ensure Environmental Sustainability
8. Develop a global partnership for Development
Quality of life depends inextricably on 3 legs:
• environment
air, water, soils, mineral resources, plants, animals, nutrient cycles, the climate…
• economics
such as employment, income, wealth, markets, trade, technologies…
• sociopolitics
such as governance, justice, education, health care, science, culture & the arts, liberty, privacy…
Why can’t the MDG’s be achieved in a world vulnerable to Climate Change?
Most impacts are expected to be negative, especially for the poorest, most vulnerable nations
Water resources, coastal infrastructure, health, agriculture, and ecosystems are expected to be challenged in virtually every region of the globe
International, regional, and national institutions are ill- prepared to manage climate change impacts. Enhanced preparedness/response strategies are a global priority
New Orleans, 2005
Sometimes it paysto plan ahead…
(Scheraga, 2005)
Key Findings
• Two-pronged strategy: avoid the unmanageable (mitigation) and manage the unavoidable (adaptation)
• Mitigation & adaptation measures should be integrated & reinforcing
• Exceeding 2-2.5°
C above 1750 levels would entail sharply increasing risk of intolerable impacts. Avoiding this will require prompt action
• Mitigation: Solutions exist to avoid exceeding 2-2.5°
C & advance MDG’s
• Adaptation: We must develop technologies and disaster mitigation strategies to manage changes in water resources, coastal infrastructure, health, agriculture and environmental refugees. New thinking about natural resource planning and management, and preservation of ecosystem services are needed to cope with climatic conditions fundamentally different than the last 100 years.
The Roadmap - Mitigation
• Choose win-win solutions to avoid exceeding 2- 2.5°
C and advance MDG’s, including:
– Shifting to non-fossil fuel supply options
– Designing and deploying only coal power-plants types that can be affordably retrofitted to capture and sequester CO2
– Increasing efficiency in transportation and commercial/residential buildings sector
– Expanding use of biofuels in transportation
– Promoting reforestation and afforestation
– Achieving a tripling to quadrupling of public and private investment in energy research, development and demonstration
The Roadmap - Mitigation
• Set a new global policy framework– Achieve international agreement on target of no more than 2-
2.5°C temperature increase
– Negotiate multi-decade emissions reductions needed to achieve agreed target
– Agree to measure and reduce national energy and emissions intensity
– Respect common but differentiated responsibilities
– Establish a price on carbon emissions in all countries
– Bolster mechanisms to pay for incremental costs of low- emitting technologies for low-income countries
Wildlife can only react
But humans can anticipate
We can plan ahead…. or we can react
The opportunity - Adaptation
– Initiate regional vulnerability assessments that identify challenges and priorities (no longer happening at Federal level)
– Evaluate multiple environmental stresses and climate change in concert and develop solutions that are robust
– Develop technologies & disaster mitigation strategies to manage changes in water resources, coastal infrastructure, health, agriculture & environmental refugees
– Avoid new development on lowlying
coastal land – Bolster international development assistance to help most vulnerable
countries invest in adaptation & coping strategies– Improve the flow of information between individuals and groups to
support collective action and decisionmaking
The opportunity - Advancing Sustainable Development while addressing Climate Change
• Responding to Climate Change Can Advance the MDGs– Clean & affordable energy is essential for achievement of MDGs
– Decentralized, domestic energy sources (e.g., wind, biofuels) can generate jobs and avoid
foreign exchange needed for oil imports
– Sustainable land-use policies are vital for agricultural, forestry
• Integrated mitigation-adaptation strategies can drive investment and
growth:
– Create and rebuild cities to be climate resilient, reduce emissions and manage natural resources
– Harness advanced building designs for maximum resource efficiency & improved health
– Modern energy supplies for cooking and heating reduce wood burning associated with black
