Presentation Transcript

  1. Impacts, Adaptation, and Mitigation • Current Weather • Climate Change Impacts • Adaptation Options • Mitigation Strategies • Course Evaluations • For Friday: Exam 4! • Final Exam on Wednesday, May 7! You can review your old exams from 9-12 on May 5!

  2. Effects on Ecosystems • Carbon Fertilization: Depends on whether they are C3 or C4 plants. • Corn is at a disadvantage compared to C3 weeds in a world with higher CO2 because C4 plants do not photosynthesize as well! • Changes of Speciation within Forests • Fate of the spruce-fir ecosystem in S. Apps? • Rising Biosphere in Mountains • Marine Ecosystems • Coral Reefs

  3. Changes of Speciation within Forests

  4. Human Impacts • Floods, droughts, and climate extremes likely to increase • Global conflicts may be exacerbated • Arctic claims in response to decreasing summer sea ice? • Environmental refugees • Food shortages and higher food prices

  5. Adapting to Climate Change • Sea Level Rise: Approximately 10% of worlds population is found within Low Elevation Coastal Zones (LECZs) • 60% of population of the Netherlands lives within LECZs • Significant problem facing society! • Water Management: How to ensure adequate and clean water when quantity and dependability of existing supplies is decreasing? • Glacier retreat in tropical Andes!

  6. LECZs in Eastern U.S.

  7. Mitigation Strategies • Kyoto Protocol • CO2 emissions 5% below 1990 • Ratified by 182 countries, bi-partisan rejection in U.S. • Energy Conservation and other “Soft” Measures • Alternative Energy Sources • Wind, nuclear, solar, tidal, biomass-based fuels • Carbon Capture and Storage (CSS) • Also known as carbon sequestration and involves burying carbon in ground • Geoengineering of Global Climate
