Climate change:An introductionClimate change is challengingWhat are we doing and what gases do they emit?How do those gases raise global temperatures?Why should we trust the science?What are the impacts of climate change?Whos responsible?What do we need to do?What are we doing?What are some policy options?

Climate change is challengingResponsible behaviors: numerous and deeply embedded in all aspects of lifeMagnitude: impacts of inaction and costs of action are large Trends and timelines: population and affluence (IPAT) growing by 1.8% and 1.3% per year, technology declining by 0.7% per yearAlternatives: not available or economically unattractiveEvidence that its hard: 30 years of knowledge, 20 years of policy, yet little progressA Chart with Too Much Detail!

Source: World Resources Institute: http://www.wri.org/image/view/9529/_originalBasics of that chart:3 main gases & sources75%: Carbon Dioxide (CO2)Fossil fuels for manufacturing,transport, heat/cool, electricityDeforestation15%: Methane (CH4)Livestock and manureRice cultivation8%: Nitrous Oxide (N2O)Agricultural fertilizer

How those gasescause global warmingMany causes of greenhouse effectVery few non-human factors that can explain increases in the greenhouse effectCO2 and CH4:VERY small fraction of atmosphereN2: 78%; O2: 21%; Ar: 1%; CO2: 0.04%; CH4: 0.0002%BUT atmosphere is in equilibriumAllow short wavelength light through but block long wavelength light and re-reflect it

How do we know humans are the cause?-- Correlation of changes with human activities-- Computer models do not match observations of temperature unless human forcings are included

Generating understanding:From Ignorance To KnowledgeWhy trust the science? Why do you trust your doctor?Distinguish fact-based from value-based claimsCredible sources: expertise and trustworthinessIndividuals using scientific methodSociology of science and peer review; institutionally conservative IPCCConfirmation of predictions from theoryMultiple independent sources of same infoMultiple indicators of same trendBest explanation, not just a possible explanationAccounting for all data, not just selected dataIPCC Summarys of research:Evidence of CC is Getting Stronger1st report (1990): unequivocal detection of enhanced greenhouse gas effect not likely for decade or more2nd report (1995): balance of evidence suggests a discernible human influence on global climate3rd report (2001): new, stronger evidence that most warming observed of last 50 years is due to humans4th report (2007): most of increase in global average temps since 1950 is likely due to anthropogenic greenhouse emissions5th report (2014): It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century Slide courtesy of Greg Bothun, U of OregonImpacts of global warmingTemperature: most areas warmer; some colder; many differentPrecipitation: some areas more; some less; some differentSea level rise and wave heightsMore extreme weather: drought, floods, hurricanesEconomic lossesSpecies lossDisease vectorsSome abrupt changes or surprisesFAQs:Climate vs. weather?How can we predict climate?Global warming but regional cooling?Impacts: Glacial Retreat

21Epistemic and normative contestationEpistemic contestation: whether climate change is likely and whether benefits of action exceed its costsNormative contestation: whether averting climate change is good or should be a high priorityNormative valence: Compare discourse of $700B economic stimulus package vs. expected discourse of $700B climate change package22Psychological barriers to actionBarriers to believing climate change is occurringAssociative (System 1) processing dampens rather than heightens concernFinite pool of worryBarriers to acting on beliefPro-environmental intent may not correspond with pro-environmental impact (Swim et al. 2009, 131)Single action bias23Socio-economic causes of climate changeIPATImpact = Population * Affluence * TechnologyImpact: environmental harmPopulation: # of peopleAffluence: $ per person (income)Technology: impact per $ (carbon intensity)+1.3%/yr since 1991Doubles in 55 years (2070)-0.6%/yr since 1991Halves in 120 years (2135)Sources: Calculated based on Global: World Development Indicators, 2015+2.0%/yr since 1991Doubles in 35 years (2050)Trends in Deep Social Causes& their Implications

It's not. ~Dr.Seuss
