Class News • Ctools site: AOSS_SNRE_480_001_W12 • 2008 and 2010 Class On Line: • http://climateknowledge.org/classes/index.php/Climate_Change:_The_Move_to_Action • Projects: • In Class Review 22 March 2012: Each group should prepare about a 15 minute 5 – 10 viewgraphs of status of project. Projects will be in different stages, but should have a good idea of the scope and where you are going. This will be a time get some input and refine and focus. • This need not be polished, but should represent vision, structure, and some essential elements of knowledge.
Projects • Think about some linkages • Regional focus on Great Lakes • City focus on Houghton • University: Get Michigan Tech Role in the mix? • Interview Guy Meadows?
The Current Climate (Released Monthly) • Climate Monitoring at National Climatic Data Center. • http://www.ncdc.noaa.gov/oa/ncdc.html • State of the Climate: Global

The Official Policy is: • United Nations Framework Convention on Climate Change • Framework Convention on Climate Change
Framework Convention on Climate Change(US in part of this.) • UN Framework Convention on Climate Change (1992, non-binding, voluntary, 192 signers) • Reduce CO2 Emissions in 2000 to 1990 levels • Inventories of greenhouse gas emissions • Mitigate Climate Change • Mid-1990’s • No reduction in emissions • Evidence of warming and impacts
Development of International Approach to Climate Change 2009 1988 1992 1995 1997 2001 2007 IPCC established Framework Convention(UNFCCC) Kyoto Protocol CopenhagenAccord Scientific assessment Non-binding aim Binding emissions target Keep warming less than 2 C
Dangerous climate change? • What is dangerous?
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
Stern Report • Considered a radical revision of climate change economics. • If we don’t act now it will cost between 5% and 20% of gross domestic product (an aggregate measure of economy.) • Stands in contrast to many studies that usually come to numbers of closer to 1% • The idea that initiation of a policy with a slow growth rate will have little impact on the economy or environment in the beginning, but will ultimately become important when the nature of expenditures is more clear.
Emissions / Cap Interface between Science and Policy • 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
All Parties agree to: 4.1.b. Mitigate emissions and enhance sinks 4.1.c. Promote technology development and transfer 4.1.e. Cooperate on research and observation Developed Countries’ aim to return emissions to 1990 levels by the end of the century 1992 Convention Commitments
Assessment • Mid-1990’s • No reduction in emissions • Evidence of warming and impacts • 2001 • No reduction in emissions • Evidence of warming and impacts • 2007 • No reduction in emissions • Evidence of warming and impacts
Increase of Atmospheric Carbon Dioxide (CO2) “This generation has altered the composition of the atmosphere on a global scale through…a steady increase in carbon dioxide from the burning of fossil fuels.” --Lyndon Johnson Special Message to Congress, 1965 Link to speech Data and more information
Kyoto Protocol followed 1995 assessments • Is the Kyoto Protocol still relevant?
Kyoto Protocol • Kyoto Protocol (December, 1997, binding limits on or reduction of emissions) • Must be signed (155 signers (?186)) and ratified • At least 55 countries • That represent 55 % or more of emissions • Open for signatures on March 16, 1998 • Went into effect on February 16, 2005 • After Russia signed and ratified
Kyoto Protocol Requirements • Developed nations reduce their emissions 5.2% below 1990 emissions • Reduction (increases) vary across countries • Relaxed a little over the years to attract signers • (Treaty: U.S. 7% reduction: Actual: 12% higher in 2004, 30% by 2012) • Addresses “six” greenhouse gases (CO2, Methane CH4, Nitrous Oxide N2O, hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride) • Commitment period 2008-2012 • Set of other activities • Improve “local emission factors” • Inventories of emissions and sinks • Mitigation and adaptation plans • Environmentally sound technology diffusion to developing nations
Beyond 2012 • Conference of Parties, Copenhagen 2009 • Copenhagen Accord • Canada withdrew this year. • Nuclear disaster in Japan trumped all of the Japanese CO2 reduction.

Scale • What is the best scale to measure vulnerability and adaptive capacity? • National: • inform states on needed policy response; allow for better decision making; allows for comparison of differential vulnerability • Regional • Impacts are likely not to be defined by national borders • Local • Ground truth • Allows for the understanding of the local factors that mediate sensitivity and resilience Thanks to Maria Carmen Lemos
Regional based Initiatives • Changing very rapidly
Scales of Policy: U.S. • Pew: State-based Initiatives (Update, 2007) • Pew: State and Region Climate Action

Motivations for State Activity • Economics • States (and cities) are very aggressive at promoting policy that they perceive as offering economic advantage. • Branding: To attract, for instance, the “creative class” • Belief and Culture • Reflection of political constituencies
States can be viewed as:(from Rabe (2006)) What has changed? • Hostile to climate change policy • Michigan (Auto industry, manufacturing) • Colorado (coal and energy) • Stealth interest? • Texas (aggressive renewable portfolio) • Nebraska (sequestration site) • Out in front • California (Water, water, water?) • Northeast alliance
Policy: Regional and State and Local • California Climate Change • Regional Greenhouse Gas Initiative • United Conference of Mayors • U.S. Mayors: Climate Protection Agreement • Map of US Mayors Climate Protection Agreement • Cool Cities
Policy: Regional and State and Local • Local Governments for Sustainability • International Council for Local Environmental Initiatives (ICLEI) • ICLEI’s CO2 Reduction / Climate • National Governors Association (NGA) • NGA Transportation and Land Use • NGA Environmental Best Practices

Pielke Jr. argues • The need for technology to make solutions possible. • Inequity of wealth, access to basic resources, desire for economic growth makes energy use an imperative • Must go • From, we use too much energy, fossil fuels are cheap • To, we need more energy, fossil fuels are expensive
What tools do we have to reduce emissions? Factor Lever Approach to Policy P GDP/P TE/GDP C/TE Population management Limit generation of wealth Do same or more with less energy Generate energy with less emissions Population GDP per capita Energy intensity Carbon intensity Less people Smaller economy Increase efficiency Switch energy sources Carbon emissions = C = P * GDP * TE * C ------ ---- ---- P GDP TE GDP Technology From R. Pielke Jr. The Climate Fix
A global perspective on energy and climate To achieve stabilization at a 2°C warming, we would need to install ~900 ± 500 MW [mega-watts] of carbon emissions-free power generating capacity each day over the next 50 years. This is roughly the equivalent of a large carbon emissions-free power plant becoming functional somewhere in the world every day. In many scenarios, this pace accelerates after mid-century. . . even stabilization at a 4°C warming would require installation of 410 MW of carbon emissions-free energy capacity each day.

CO2 stabilization trajectory (2006) • Stabilize at < 550 ppm. Pre-industrial: 275 ppm, current: 385 ppm. • Need 7 ‘wedges’ of prevented CO2 emissions.
Use of climate information • Research on the use of climate knowledge states that for successful projects, for example: • Co-development / Co-generation • Trust • Narratives • Scale • Spatial • Temporal Lemos and Morehouse, 2005
