The Biggest Sources of Greenhouse Gases THAWING PERMAFROST AIR TRANSPORT COAL MINING COAL PLANTS OIL PRODUCTION CROP BURNING INDUSTRIAL PROCESSES ID #3622 - Can be used in noncommercial online and TV broadcasts of your presentation, but not modified. DESCRIPTION: Graphic representation of major sources of greenhouse gas emissions ADDITIONAL TALKING POINTS: Most of the global warming we’re seeing today is caused by carbon pollution from fossil fuels.* Other important contributors include deforestation, transportation, agriculture (crops and livestock), and industrial processes.** REFERENCES: * Union of Concerned Scientists, “Why does CO2 get most of the attention when there are so many other heat-trapping gases (greenhouse gases)?," last accessed August 8, 2016. http://www.ucsusa.org/global_warming/science_and_impacts/science/CO2-and-global-warming-faq.html ** United States Environmental Protection Agency, “Global Greenhouse Gas Emissions Data," last updated August 2, 2016. http://www.epa.gov/climatechange/ghgemissions/global.html FERTILIZATION FOREST BURNING INDUSTRIAL AGRICULTURE LAND TRANSPORTATION LANDFILLS Melcher

Climate change in Oregon Water Resources Forests Agriculture Coasts and Ocean

Water Resources Mountain snowpack River and stream levels

Advanced technology Semiconductors and electronics OR’s largest industry: Employment ~ 85,000 Water use ~ 2-4 million gallons per day (a small city!) Increased costs of hydroelectric power

Oregon Forests Store carbon Filter pollutants Stabilize soils Recreation Endangered species habitat

Sustainable timber Bioenergy

Climate change risks to OR Forests Increased incidence of forest fires

Risk factors from climate change: Higher temperature Less rainfall (2015 drought) Med. scenario – 4x more by 2080 (2 million acres/year)

Other impacts of climate change on forests Mountain pine beetle Human health risk from fires Insect predator risk

Oregon Agriculture: $5B in 2008 Vulnerable: water shortages, extreme summer heat, increased insect pests

Oregon wineries Narrow optimal climates for grape varieties Higher costs from changed plantings

Oregon beer! Benefits from: Moderate climate Abundant rainfall Oregon hops Benefits from: Moderate climate Abundant rainfall Fertile soil

Estuaries – at risk from algal blooms Oregon Coast Estuaries – at risk from algal blooms Lincoln City, OR

Shellfish Harvest – OR coast Direct risks from ocean acidification

Oregon salmon fisheries Indirect risks from disrupting marine web
