- Generation of energy from land fill waste- Saving energy by reducing natural gas flaring and pipeline leaks- Reducing risks of coal mine tragedies by harvesting of methane gas- Manure to energy transformation- Improved animal husbandry- Health--oriented efforts to level rapidly growing global meat demand
Magnitude of BC warming effect is an area of active research - BC emissions and atmospheric concentrations are only rough estimates. A satellite soon to be launched will provide better data. - Many emissions of BC are accompanied by emissions of organic carbon and sulfates, both of which are coolants. - BC pArcticles may have an indirect cooling effect by helping clouds to form.
“During 1976-2007, we estimate that aerosols contributed 1.09 ± 0.81˚C to the observed Arctic surface temperature increaseof 1.48 ± 0.28˚C.”
50% GHG Emissions Reduction by 2050, 80% by 2100 Note that aggressive CO2 reductions are needed now in order to keep CO2 levels even barely manageable in 2100. CO2 cannot be set aside.
- Comparing the two previous slides out to 2040 (one generation)- Reducing CO2 only will not alter warming trends out to 2040. - Many scientists fear the consequences of warming before 2050, including passing tipping points such as summer-free ice in the Arctic. Black carbon reductions offer the largest potential to quickly alleviate some level of global radiative forcing.

Biomass Burning - LargestCurrent Arctic Climate ForcerS Recent studies indicate that about75% of light absorbing aerosols(black and brown carbon)deposited on Arctic snowand ice are attributable to cropand grass burning (Hegg etal, 2010).S ARCTAS mission found itcontributed 39 %of Arctic blackcarbon, 69 %of Arctic methane and38 % of Arctic carbon monoxide, aprecursor of troposphericozone.(Wedderburn-Bisshop, 2012).S Agricultural and grassland fires areresponsible for 69 % of Arctic fireactivity with forest and shrubland firesresponsible for 24% (Wedderburn-Bisshop, 2012).
Biomass Burning - LargestCurrent Arctic Climate ForcerS The leadsourcesof these emissions in descending order areRussia, Kazakhstan, China, United States, Canada and Ukraine (Pettus, Clean AirTask Force, 2009).S Most of these nations have some form ofrestrictions on agricultural burning butenforcement is generally lax, especially inplaces such as northeast China whereemissions are most likely to affect the Arctic(Pettus, 2009).S Potential mitigation strategies mightinclude increased enforcement of existingrules and changed seasonality of burning.
Arctic Air Overflights - A Source ofBlack Carbon and Other ClimateWarming EmissionsS Beginning in 1998 when Russiaagreed to permit foreign carriercommercial aviation overflightsthis has grown to over 40,000flights a year with significantclimate forcing effect.Especially significant is theresidence time of black carbonemitted in the stratosphere, asmuch as an order of magnitudegreater than at ground level(Jacobson et al. 2012)S Mark Jacobson at Stanford andcolleagues, after an extensive analysisof trans- Arctic flights, concluded itwould be possible to reduce emissionsby as much as 83 % by rerouting. Theyproject this could significantly delayloss of Arctic sea ice with annual costsglobally of about $ 99 million.(Jacobson et al. 2012).
Arctic Air Overflights - A Source ofBlack Carbon and Other ClimateWarming EmissionsS Breakthroughs in early June by members of International AirTransport Association (IATA) in urging governments to adopt asingle market based system to offset post -2020 growth inaircraft emissions may be a heartening sign of growing airlinereceptivity to climate friendly activity.
Development Related to ArcticWarming Produces SizableEmissions GrowthS Shipping - Volume likely to increase as sea ice meltsS Potential response -Requiring electrostatic precipitators orchanged fuel mix to minimize black carbon emissions on bothcommercial vessels and icebreakers.S Oil and gas development -Likely to increase, especially in Russiaand some other offshore parts of Arctic and near Arctic.S Potential response - Besides seeking universal provisions tominimize oil spills, encouraging near zero black carbon emissionsand zero methane releases.S Mining- Although a modest source of emissions, mostly in Russiaand Canada, there is large potential for growth of mining industryin Greenland with international investors looking to extract ironand rare earths.
Possible RegionalGeoengineering StrategiesS Changing seasonality oficebreaking- doing less icebreaking in the spring when itreinforces sea ice loss and more inthe fall.S Catalyzing natural processes toabsorb Arctic methane-researchersare looking at use of supplementssuch as nitrate or sulfate to boostproductivity of methanotrophs.S Bacteria are responsible for aerobicmethane oxidation; archea areresponsible for anaerobic oxidation.This might reduce methane release inArctic oceans, as well as promote amore suitable climate for fishhabitation, and thereforefor fishfarms.S Sending small ships to dispersesea salt, forming clouds to hold inArctic heat- Salter and Latham anda UK based Arctic MethaneEmergency Group have been theleading advocates for this strategy.
The Four Crucial RegionsHimalayasAmazonian Rainforest &Andean Mountains
South America: CloselyInterconnected EcosystemsAmazon RainforestS The Amazonian Rainforest is thegreatest treasure trove of biodiversityon the planet.S It is disappearing rapidly due to landconversion for cattle farms, mining andsmall farmers.S Brazilian Scientists (Simoes&Evangelista) report that emissions fromburning for land clearing in theAmazon, especially for cattlefarms, may be producing as much ashalf of black carbon deposition in theAntarctic.Andes MountainsS Glaciers in the mountains providewater supplies for tens of millionsin South America and hydropowerfor millions.S Rapid glacial melt imperils thiswater supply.S Efforts are underway to installcleaner cook stoves in manyAndean communities and reduceblack carbon emissions.
AntarcticaS Glacial thinning:Glaciers in Antarctica containabout 70% of all the freshwater on Earth; if all were tomelt, global sea levels wouldrise well over 60 meters-more than 200 feet.
AntarcticaS There is a modest net loss nowfrom Antarctica, about 150cubic kilometers each year(Hansen, 2007) but if thisaccelerates it could add significantlyto global sea level rise.S Deposition of significant quantities ofblack carbon from fires inSouth America and Africa hasbeen detected in Antarctica andlinked to agricultural burning. Nolinkage has yet been done ontheir role in ice loss.S Although Antarctica is the coldestregion on Earth, some portions in theAntarctic Peninsula and WestAntarctic are among the mostrapidly warming parts of the planet.S Most Antarctic ice loss seemsattributable to interaction withwarming waters of the SouthernOcean more than to warming on theland.
Himalayas – Tibetan PlateauS Emissions of blackcarbon, especially from dieseltransport and cookstoves, appear as great a factoras overall global warming inspurring glacial melting.S Indian Supreme Court hasmandated that in public transportcompressed natural gas vehiclesreplace current diesel and othervehicles.S Provides water supplies for aboutone of every six humans onearth. Rapid glacial melt underwaythat may reduce water availability.S Project Surya seeks to reduceblack carbon emissions, save livesand reduce climate forcing throughreplacement of cook stoves andkerosene lanterns with cleaneralternatives http://www.projectsurya.org/

Significance forInternational SecurityS Accelerated glacial melting inGreenland and Antarctica couldenhance projected sea levelrise, threatening the US, other coastalnations and island states.S Potential unpredictable effects onweather patterns and worldagriculture at loss of year roundArctic Sea Ice.
Arctic Climate ActionRegistry (ACAR)S An effort to incentivize reductions of emissions of soot, methane andtropospheric ozone forming compounds.S No other organization in the world is taking action fast enough to savethe Arctic. The Arctic Climate Action Registry will certify projects thatimmediately slow the meltdown in the Arctic using metrics defined in thenew Draft American (ANSI) Greenhouse Gas Accounting Standard.S The Arctic Climate Action Registry Network is a social networkconsisting of scientists, business leaders, governmentofficials, educators, and consumers. Its goal is to help memberscommunicate about taking action to save the Arctic.S If successful, could be adapted and extended to the Antarctic, Amazon-Andes and Himalayas.
ACAR Vision, Missionand StrategyS VISION: Slow down and ultimatelyend climate change in the Arcticregion and, in so doing, slow downclimate change around the globe.S MISSION: Mitigate greenhousegases and other climate forcersaffecting the Arctic region.S STRATEGY: Stimulate projects andactivities in support of ourmission, based on incentives andmarket mechanisms, withmeasurable progress within thedecade.

ACAR Registry ProjectOpportunitiesExamplesShipping – Equipping ships with technology to capture blackcarbon, and using or purchasing turbine-powered ships.Agricultural Burning - Reduce and change seasonalityAirlines– Reduced emissions from airline fleets, e.g., some reroutingof flights, increased fuel efficiency.Pollution Prevention –Stack emissions captured at electricityproduction and other industrial facilities.Methane Capture – Methane capture for energy generation.Natural Cycle Enhancement – Micronization of sea water to helpcool the region, i.e., ships generating spray to promote cooling.
Some Encouraging TrendsU.S. Greenhouse GasesS Total emissions levels havedropped almost to 1994 levelsdue largely to increasedefficiency and greater use ofrenewables.S Should continue by a substitutionin U.S. of natural gas for coal inthe utility sector.S To maximize climate benefits ofcoal to gas switch, it is crucial tominimize methane leaksfrom natural gas system.Energy Use &Emissions
U.S. Position: OpportunityS Leverage our good fortune assoon-to-be world’s leadingenergy producer; ensurecontinued prosperity andcatalyze effective national andinternational response toclimate change.S In natural gas sector: holdoverall methane leakagefrom natural gasextraction, transmissionand distribution to below1%.S How can our energy planningand foreign policy promoteresults that will sustain ournational economy, reduce riskof climate disruption, and meldinto climate protectionresponses, benefits to humanhealth and food production?
U.S. OpportunitiesS Wide political support here. April22, 2009, joint sponsorship ofsuccessful legislation by SenatorsInhofe, Carper, Boxer and Kerry tomandate U.S. EPA to developoptions for black carbonreductions here and abroad.S Encourage special focus onemission reductions in regionssuch as Arctic, where we may beat near irreversible climatetipping points.S Reduce federal and stateregulatory barriers to energy recycling(cogeneration).S Promote aggressive internationalattack on Short- Lived ClimateForcers that affect climate andhuman health and where benefitscan be realized soon.
China Moving Forward inClimate ProtectionS As RamezNaam noted in Slate May 8, 2013 China now seems determined tobe a world leader in climate protection:1. Moving forward with a cap andtrade plan in seven regions Includingprovinces of Guangdong and Hubeiand cities ofBeijing, Shanghai, Tianjin, Chongqingand Shenzhen, with a goal of linkingby 2020 to a national carbon market.2. Planning to institute a tax on CO2emissions, as early as 2015 or 2016.
China Moving Forward inClimate Protection3. Investing $65 billion on renewable energy in 2012,compared with $35 billion in the US the same year.4. China now produces over half of the globalproduction of solar panels with the US nowproducing less than 10 percent.Significantly, driven by both climate and air qualityconcerns, China appears to be considering theintegration of valuation for reduction of emissionsof black carbon and other short- lived climateforcers into their cap and trade plans.

A Region SpecificMitigation StrategyS Himalayan-Tibetan Plateau: rapid glacial melt imperils the watersupplies of much of humanity; mitigation action (cleaner cook stoves andtransport systems) can avert hundreds of thousands of air pollutiondeaths annually.S Latin America: glacial melt in the Andean region and drying out of keyagricultural lands in South America is spurred by burning and landconversion.S ACAR to leverage growing public interest in slowing climatic disruption inthe regions closest to a tipping point, corporate interest in avertingclimatic chaos and voluntary emission reduction incentive systems toslow loss of sea ice and glacial melting.ACAR TARGET: Black carbon, ozone forming compounds andmethane
