Assessment • Bringing together knowledge to evaluate that knowledge as a body of work relevant to some specific subject or application. • What can we say about climate change? • What are the gaps in knowledge? • How certain are we? • Reconcile conflicting information? • How the scientific community communicates with policy makers

Land Use / Land Change Other Greenhouse Gases Aerosols Internal Variability Validation Evaluation Consequences Feedbacks Air Quality “Abrupt” Climate Change Summary Points: Science Correlated Observations CO2 and Temperature Observed to be strongly related on long time scales (> 100 years) CO2 and Temperature not Observed to be strongly related on short time scales (< 10 years) Theory / Empirical Evidence CO2 and Water Vapor Hold Heat Near Surface Prediction Earth Will Warm Theory / Conservation Principle Mass and Energy Budgets Concept of “Forcing” Observations CO2 is Increasing due to Burning Fossil Fuels
We conclude Earth will warm • Does it matter? Is it dangerous? • Do we respond to this knowledge? • How do we respond?
One Response: Policy to Solve it KNOWLEDGE CLIMATE SCIENCE POLICY UNCERTAINTY PROMOTES / CONVERGENCE OPPOSES / DIVERGENCE
Framework for Response • Our framework for responding to climate change is summarized at the highest level by mitigation and adaptation.
Science, Mitigation, Adaptation Framework Adaptation is responding to changes that might occur from added CO2 It’s not an either / or argument. Mitigation is controlling the amount of CO2 we put in the atmosphere.
Some definitions: (IPCC Glossary) • Mitigation: The notion of limiting or controlling emissions of greenhouse gases so that the total accumulation is limited. • Adaptation: The notion of changes in the way we do things to adapt to changes in climate. • Resilience: Amount of change that can be accommodated without severe damage. • Adaptive Capacity: Ability to adjust to moderate potential damages. • Geo-engineering: The notion that we can manage the balance of total energy of the atmosphere, ocean, ice, and land to yield a stable climate in the presence of changing greenhouse gases.
Thinking about ADAPTATION • Adaptation: What people might do to reduce harm of climate change, or make themselves best able to take advantage of climate change. • Autonomous that people do by themselves • Can be encouraged by public policy • Command and control tell you to do it • Incentives • Subsidies • Can be anticipatory or reactive • Adaptation is local; it is self help. • Adaptation has short time constants - at least compared to mitigation Hence people see the need to pay for it. • Some amount of autonomous-reactive adaptation will take place. • Moving villages in Alaska
Thinking about MITIGATION • Mitigation: Things we do to reduce greenhouse gases • Reduce emissions • Increase sinks • Mitigation is for the global good • Mitigation has slow time constants • Mitigation is anticipatory policy • This is the “second” environmental problem we have faced with a global flavor. • Ozone is the first one. Is this a good model?
Some Mitigation-Adaptation considerations • Those who are rich and technologically advanced generally favor adaptation; they feel they can handle it • Plus, technology will continue to make fossil fuel cheap, but with great(er) release of CO2 • Those who are poor and less technologically advanced generally advocate mitigation and sharing of adaptation technology • Emission scenarios don’t matter for the next 30-50 years. • There are a lot of arguments, based on economics, that lead towards adaptation • Mitigation always looks expensive, perhaps economically risky, on the time scale of 50 years. • Adaptation looks easier because we will know more • This will remain true as long as the consequences seem incremental and modest • The Innovators Dilemma, evolution vs revolution?
Responses to the Climate Change Problem Policy/ Societal Autonomous/ Individual Anticipatory Reactive Mitigation Adaptation
A Management Idea The first and largest improvements come from a plan, an approach to the problem, and identifying mistakes early This axis is ability to target cost, quality, time
Policy: Global and Local GLOBAL CONSEQUENCES LOCAL POLICY (ADAPTATION) SURFACE WARMING GLOBAL POLICY (MITIGATION) GREEN HOUSE GAS INCREASE
IPCC projections: Where is the challenge of mitigation? Takes a long time to separate
Framework for response • What is dangerous climate change?
Stern Report: Influential: Useful for thinking about problem • Draws on recent science which points to ‘significant risks of temperature increases above 5°C under business-as-usual by the early part of the next century’ — other studies typically have focused on increases of 2–3°C. • Treats aversion to risk explicitly. • Adopts low pure time discount rates to give future generations equal weight. • Takes account of the disproportionate impacts on poor regions.
Dangerous climate change? Stern, 2006
Some carry away messages • Determine what is a tolerable ceiling for carbon dioxide. • Gives cap for a cap and trade system. • Tolerable ceilings have been posed as between 450 and 550 ppm. • Ice sheet melting and sea level? • Oceanic circulation / The Gulf Stream? • Ocean acidification? • Determine a tolerable measure of increased temperature • Copenhagen Accord (2009) 2o C
Dangerous climate change? Stern, 2006
Framework for Response • Stabilization: That we can manage our emissions so that the amount of carbon dioxide, more generally, greenhouse gases, so that we control the amount in that atmosphere at a stable level one small enough to avoid dangerous climate change.
