  1. Dealing with Change

  2. My NASA Data • Pick a problem • Resolve the problem • Report the result

  3. Earth as A System • What are the interconnected factors

  4. Predicted precipitation changes • Overall increase in precipitation • Some areas (Arctic, Sahara, Antarctic) become wetter • Other areas become drier Annual mean precipitation change: 2071 to 2100 Relative to 1990 Source: IPCC, 2001

  5. Carbon Cycling Figure ES.15 The Carbon CycleCourtesy NASASource: http://earthobservatory.nasa.gov/Library/CarbonCycle/carbon_cycle4.html There is actually very little of the total carbon cycling through the Earth system at any one point in time. Most of the carbon is stored in geologic deposits - carbonate rocks, petroleum, and coal - formed from the burial and compaction of dead organic matter on sea bottoms. The carbon in these deposits is normally released by rock weathering.

  7. What’s your carbon footprint? • Where do you live? • How many people live in your home? • What type of vehicle do you drive and how many kilometers per year? • How often do you fly? Are these short or long trips? • Do you heat your home with natural gas, heating oil, propane, or electric? • Do you eat red meat, just chicken or fish, or are you a vegetarian? • Do you eat mostly local foods and buy mostly local products, or do you prefer imported goods? • What types of recreation do you prefer?

  9. The System Issues • Sell off the beach house! • Loss of ecosystems • Goodbye coral reef rows (60% by 2050) • Extinction (1.6C 9% to 31% of species go extinct) • Floods and Droughts • More air pollution • War • Famine (less water, less food) • Pestilence and death • Earth, wind and fire in N America • Too wet and hot in Europe • Polar meltdown

  10. What are you to do, citizen of the earth?

  11. A last thought… For in the end we will conserve what we love, We will love only what we understand, We will understand only what we are taught. Baba Diorum, 1968, Senegalese envrionmentalist Be safe, be well….

  12. The Seven Revolutions • Global Strategy Institute (http://gsi.csis.org) a part of the Center for Strategic and International Studies, conducted a study “to identify and analyze the key policy challenges that policymakers, business figures, and other leaders will face out to the year 2025.” • SEVEN areas of change are expected to be the most revolutionary

  13. The Seven Revolutions • Population • Resource Management • Technology • Information Flows • Economic Integration • Conflict • Governance

  14. 1. Population • 9.2 billion by 2050; greatest growth by those least able to cope with the increase • A generation gap by 2047 • Migration and Urbanization; 60% will live in cities

  15. 2. Resource Management • Food – production must increase • Water – availability, quality, sanitation • Energy – demand for hydrocarbon will not decrease

  16. Carbon Sequestration http://www.meic.org/images/energy-images/carbon-sequestration/energy-4.jpg/image_view_fullscreen
