I will be showing at least a few slides on each. There is a big new idea here. I am a science teacher. A teacher’s job is to prepare students for what lies ahead of them. We want especially to make our students comfortable with ideas that were not familiar to previous generations. There is a big new idea here. Human beings are able to change the small planet we live on For the first time in history, for better or for worse, human beings are powerful enough to affect the whole planet. Forests have been cleared and fisheries have been depleted on a global scale. Most of the low-cost oil has been found. The surface oceans are already more acidic. These are quantitative observations. Our new assignment: “Fitting on the planet.” Our exuberance is the problem The Earth’s smallness is the result of the dominance of democratic values, consumer values, and the values of self-realization. The collision with environmental limits was prominently foretold in the 1970s (e.g., Limits to Growth), but we chose to shoot the messenger rather than to heed her. Don’t shoot the messenger Twice before, the messenger was shot. Galileo argued that the earth wasn’t at the center of the universe and was excommunicated. Darwin argued that human beings were part of the animal kingdom and was cruelly mocked. This is a similar time. We can change the planet. The idea that humans can’t change our planet is as out-of-date and wrong as the earth-centered universe. We would much rather live on a planet that was harder to change. When the first doctor we consult brings us a diagnosis we don’t like, we should seek a second opinion. But there’s a time to move on. Grounds for optimism •The world today has a terribly inefficient energy system. •Carbon emissions have just begun to be priced. •Most of the 2060 physical plant is not yet built. •Very smart scientists and engineers now find energy problems exciting.

If the OECD takes efficiency seriously, annual consumption from now on could be less than in any past year – for both: •oil consumption •electric power consumption China’s appliance standards Business as Usual: CO2 emissions from air conditioners in 2020 are 9x those in 2000.

[email protected] Zero minus zero equals zero If there is no load growth* and there are no retirements, then nothing new is needed. *Demand can grow in some regions and fall in others. The future coal power plant Shown here: After 10 years of operation of a 1000 MW coal plant, 60 Mt (90 Mm3) of CO2 have been injected, filling a horizontal area of 40 km2 in each of two formations. Assumptions: •10% porosity •1/3 of pore space accessed •60 m total vertical height for the two formations. •Note: Plant is still young. Injection rate is 150,000 bbl(CO2)/day, or 300 million standard cubic feet/day (scfd). 3 billion barrels, or 6 trillion standard cubic feet, over 60 years. U.S. CO2 pipeline infrastructure Denbury proposes to send Indiana CO2 to the Gulf states. An Ohio Valley CO2 pipeline network instead? Advantages: More local jobs Greater storage volume Less climate change.

Socolow & Alexander Glaser, “Balancing risks: nuclear energy & climate change,” Daedalus, 2009. Proliferation and the futility of a two-tier, supplier-user world A Story: In May 2006, in Delhi, I asked several leaders of the Indian nuclear enterprise to comment on the merits of a supplier-user arrangement of the world. They refused to do so until they knew in which category India would be. If the U.S. had informed them that they were users, would they have gone underground? Wise global nuclear power • Safety: Create counter-incentives to plant relicensing, so that aging plants are retired. • Storage: Revise the contract with society in favor of retrievable storage. Deploy dry-cask storage. • Proliferation, plutonium: Indefinitely postpone U.S. reprocessing and end reprocessing elsewhere. • Proliferation, uranium: Place all enrichment facilities, including ours, under international governance. • Governance: Establish a one-tier world.

Conservation Regimentation Renewables Competing uses of land “Clean coal” Unsafe mining, land impacts Nuclear power Nuclear war Geoengineering Technological hegemony Risk management We must trade the risks of disruption from climate change against the risks of disruption from mitigation… …and search for an optimum pace. Hippocratic oath I will apply, for the benefit of the sick, all measures that are required, avoiding those twin traps of overtreatment and therapeutic nihilism.* * Modern version, Louis Lasagna, 1964, http://www.pbs.org/wgbh/nova/doctors/oath_modern.html Safe vs. Fair Safe vs. Fair If “fair” is a per capita concept and the unit of attention is the nation: Safe is not fair. Fair is not safe. Including historical emissions, “fair” is in even sharper conflict with “safe.” Beyond per capita We can’t solve the climate problem without moving beyond “per capita” – looking inside countries. Where do the “high-emitters” live? We project that in 2030, 1.2 billion “high-emitters” will be responsible for 60% of the world’s emissions… … and half of these high-emitters will live outside the OECD.

Required: a multiplicity of empathies Planetary and collective Local and individual Abstract Vivid Uncertain risks, havoc possible Bounded outcomes Entails a half-century of action Produces benefits in days The developing world will decide what kind of planet we live on. For a while longer, the industrialized countries will lead. Post-post-colonialism The North-South relationship needs marriage counseling. The two partners are not listening to each other. The UNFCCC, a post-colonial institution, affirms a two-tier world. Annex I expresses guilt. Non-Annex I expresses entitlement. Needed: post-post-colonial institutions. Planetary identity In the process of taking climate change seriously, we develop a planetary identity. We augment our previous loyalties to family, village, tribe, and nation. Do you have a planetary identity? Prospicience Prospicience: “The art [and science] of looking ahead.” In the past 50 years we have become aware of the history of our Universe, our Earth, and life. Can we achieve a comparable understanding of human civilization at various future times: 50 years ahead – vs. 500 years and vs. 5000 years? We have scarcely begun to ask: What are we on Earth to do?
