  1. Actions to Limit Climate Change SNC2D1 Grade 10 Science

  2. Predicting Future Climate • Climate projection: scientific estimate of future climate conditions based on observations and computer models Red: if we continue burning fossil fuels Blue: if we change to using clean energy

  3. Switching from fossil fuels to clean energy sources is one of the main ways to reduce the impacts of human activity on climate

  4. Renewable Energy Sources • Wind power • Geothermal energy • Solar power • Hydroelectricity • Biofuels • Nuclear power

  5. Green Roof Technology • Video 1 (BCIT): • Green_Roof_Soiling_at_BCIT_-_3_Blog_Nights__SAT_-_5AM_.mp4

  6. Vancouver Convention & Exhibition Center (VCEC)

  7. Green roof technology • Plants absorb sunlight for photosynthesis • Provide insulation for buildings • Stay cooler in hot weather • Absorb storm water • Improve air quality • Reduce noise pollution • Create a link between fragmented habitats

  8. Global Temperatures • Already risen by 0.74˚C over the last 100 years • Should limit increase to 2˚C to avoid dangerous impacts of climate change = 450 ppm of greenhouse gases (GHG) Effects of El Nino and La Nina

  9. Reducing GHG Emissions Provincial level (Ontario) • Target: reduce by 6% by 2014 • Go Green: Ontario’s Action Plan • Stop coal-fired generators by 2014 • Approve renewable energy projects • New improved rapid transit routes in GTA & Hamilton • Plant 50 million trees by 2020 • Ontario Stewardship Rangers – summer jobs for 17yr olds

  10. Reducing GHG Emissions • Municipal level (Toronto): • Conserve energy and reduce GHG emissions by • 6% by 2012 • 30% by 2020, • 80% by 2050 • Creating green jobs • upgrading appliances, energy efficient lighting, building improvements

  11. What Canadian businesses & industries can do:

  12. What Canadian businesses & industries can do:

  13. Brainstorm What can YOU do to reduce your greenhouse gas emissions?

  14. What can you do? • Walk, bike, public transport, car pool • Buy fuel-efficient cars • Switch off lights & unplug appliances • Fly less • Use less A/C & heating • Plant trees • Conserve [hot] water

  15. Benefits: • protect people’s health • saves money • improves your city or town • protects traditional activities • protects the environment
