2 To Start To postpone climate tipping points, we must reduce global warming within 20 years. But current mitigation has only hastened climate change. Why? Climate metrics have not been updated since Updated climate metrics are needed to postpone tipping points. Scientific Certification SCS Global Systems Services 2

21 Coolants Are Still Slowing Global Warming Scientific Certification SCS Global Systems Services 21
22 Coolants Are Still Slowing Global Warming National Academy of Sciences (2013): The Chinese economic expansion led to a huge increase in sulfur emissions, which has had a cooling effect. All that sulfur pollution in the air from China s massive coal-burning was largely responsible for the leveling of [global warming] between Dr. Robert Kaufman, Boston University.

US EPA plans to fight global warming by removing coal plants, reducing CO 2 emissions. What else will happen? Further reductions in coolants. Scientific Certification SCS Global Systems Services 23
24 The Unintended Consequence of Reducing CO 2 from Coal Scientific Certification SCS Global Systems Services 24
25 The Unintended Consequence of Reducing CO 2 from Coal UNEP-WMO 2011 SO 2 is co-emitted with CO 2 in some of the highestemitting activities, including coal burning [ ] in power plants. Hence, CO 2 [mitigation] alone may temporarily enhance near-term warming as sulfates are reduced. Scientific Certification SCS Global Systems Services 25

33 And Health Impacts As Well UNEP on Indian Hot Spot: Black Carbon Causes Local Climate Impacts Not Related To Global Warming: +14 W/m 2 local warming 20% Decrease in Rainfall 6% reduction in sunlight Scientific Certification SCS Global Systems Services 33
34 A large part of this PM is black carbon. And Health Impacts As Well UNEP on Indian Hot Spot: Black Carbon Causes Local Climate Impacts Not Related To Global Warming: +14 W/m 2 local warming 20% Decrease in Rainfall 6% reduction in sunlight This air pollution kills 7 million per year in developing countries.

41 How Did We Get Here? Scientific Certification SCS Global Systems Services 41
42 The Mitigation Control Point All mechanisms disperse funding using the GWP-100 climate metric. Last GWP-100 update: 1997 Scientific Certification SCS Global Systems Services 42
43 GWP-100 Leaves Out 60% Of Climate Pollution GHGs in Current Footprints Radiative Forcing Carbon dioxide 1.8 W/m W/m 2 (40%) 1.8 W/m 2 (30%) Methane Short-Lived 0.5 W/m 2 Radiative Nitrous oxide Climate Forcers 0.2 W/m 2 Forcing Other GHGs Black carbon 0.3 W/m W/m 2 Total Brown carbon 2.8 W/m W/m 2 Cooling Climate Tropospheric Ozone Forcers 0.4 W/m 2 Total Cooling 1.8 W/m aerosols 2 (sulfate, nitrate, and organics) -2.1 W/m 2 (30%) Radiative Forcing -2.1 W/m 2 Scientific Certification SCS Global Systems Services 43
44 GWP-100 underestimates short-term impacts of methane by 80% IPCC 1997: x21 over 100 years IPCC 2013: x36 Over 100 years NASA Scientists: x105 Over 20 years CO 2 Scientific Certification SCS Global Systems Services 44
45 GWP-100 Assumes We Have 100 Years to Solve the Problem Scientific Certification SCS Global Systems Services 45
46 Shortcomings mean policies based on GWP-100 cannot avoid tipping points IPCC 2013: GWP-100 is not well suited for policies with a maximum temperature target In 2010, what did 195 countries agree on? Emissions need to be reduced so that global temperature increases are limited to below 2 C. Scientific Certification SCS Global Systems Services 46
47 What to do with $350 billion? To postpone tipping points, updated climate metrics are needed to reapportion available funds. Scientific Certification SCS Global Systems Services 47
