17 2050s (2041 to 2070) More frequent extreme heat More rainfall & flooding Longer warm season Based on seasonal average temperature and precipitation

18 Days Above 90 ºF Annual Count 14 PAST Where we end up depends on the choices we make! FUTURE 2050s FUTURE 2080s Future data based on high emissions scenario 2050s represents 30-year period 2041 to 2070 Elkhart County, Indiana

19 Annual Statewide Average Temperature Reducing emissions matters! INDIANA

20 How does waste fit into this? Emissions from landfills Methane Carbon dioxide Nitrous oxide Landfills are the 3 rd largest sources of human-related methane emissions

21 How does waste fit into this? Emissions from landfills Methane Carbon dioxide Nitrous oxide U.S. EPA, 2009 U.S. Emissions by sector (2006)

22 of U.S. GHG emissions are associated with the energy used to produce, process, transport, and dispose of the food we eat and the goods we use. Systems-based assessment of U.S. emissions (2006) U.S. EPA, 2009
