  1. Why study GLOBAL WARMING? www.noaanews.noaa.gov/ stories/s412.htm

  3. As Habitats Change • Species distributions are changing • Some animals are moving toward the poles • Some are moving up mountains • Many are losing habitat, migration routes

  4. Plants and Disease • Agricultural crops may be affected as local weather and seasons change • Insect population explosions • Invasive species • Disease distributions: malaria, cholera, etc http://www.mindfully.org/Air/Global-Warming-Health20aug00b.GIF www.uaf.edu/.../2004/ ninilchik-beetles.html

  5. Increased severe weather: droughts, floods, hurricanes http://magma.nationalgeographic.com/ngm/0409/feature3/zoom5.html

  6. “More than a hundred million people worldwide live within three feet of mean sea level.” ~National Geographic fact http://www.ourbangla.com/bangladesh/pg/flood/FLOOD_JESSORE_17_8AP_JWH_s0.jpg

  7. Causes: Greenhouse gases • Burning fossil fuels • Forest fires • Volcanoes • Deforestation www.ctv.ca/.../ 1038431872899_41?s_name=&no_ads=

  9. Collapsing ground from melting permafrost • Melting sea ice http://climchange.cr.usgs.gov/info/assessment/tok.jpeg http://www.phenology.org.uk/standard/home/why/images/polalbearsicemelt.jpg http://www.ciel.org/Pictures/ice_arch.jpg

  10. REDUCE CO2 Emissions! • Clean Electricity / Alternative Energy • Smart Transportation and Land Use • Healthy Farms and Forests • Promote Conservation / Restoration • Make Greener Choices

  11. So how do ecosystems respond to elevated CO2? • Study site: Cheyenne, WY • Treatments: • Elevated CO2 • Heating • Changing rainfall patterns • CO2 sink or source?

  12. What is happening belowground?

  13. CO2 fluxes…. Responses to rainfall
