  1. Carbon Footprint

  2. What does carbon footprint mean? • a measure of the impact our activities have on the environment (climate change) • It relates to the amount of greenhouse gases produced in our day-to-day lives through burning: • fossil fuels for electricity • heating (oil or propane furnaces) • transportation • Measured in tonnes (or kg) of carbon dioxide equivalent. • Developing/supporting renewable energy sources like wind power can help us reduce our carbon foot print

  3. Why does it matter how much carbon I produce? • Because there are 7 Billion “I’s” on Earth • In October 2011 the world population broke the 7 billion people mark • If everyone says someone else will do it, we have 7 million people not helping to solve the problem • Businesses alone can not solve this problem, but they do have a role

  4. Why does carbon dioxide matter? • It is a green house gas • This means that it helps to trap solar radiation in the Earth’s atmosphere • Most scientists agree that the world’s temperature is going up • Most scientists agree that the increase in temperature is melting ice caps—causing sea levels to increase

  5. So? Why do I care about polar bears? • They are cute • We shouldn’t just kill them because we can • Because melting ice becomes water…

  6. Melting ice becomes water? • So you don’t care about polar bears • You don’t think they are cute • You could care less if they become extinct • You think Coca – Cola will find a new mascot • Then be selfish—if water levels rise because of the melting arctic ice fields…

  7. We could all be sunk

  8. Rising Ocean Level Predictions • Some predictions estimate that if all of the sea ice melts ocean levels could increase by 61 m • There is very little agreement about the rate of sea level rise, but there is agreement it is happening • Many predictions suggest a 1 m increase in the next 100 years

  9. If sea level rises about 1m in Halifax: - the blue area will be water - the yellow area is where storm surge will stop

  10. What does that really mean? • Over 600 million people live in coastal areas that are less than 10 meters above sea level • Two-thirds of the world’s cities that have populations over five million are located in these at-risk areas • Underwater cities could become a reality

  11. The Lost City of Atlantis or Halifax?

  12. Rising Global Temperatures • Scientists do not agree on the rate of temperature increase, but most do agree an increase is happening • IF global temperatures rise we could experience: • Stronger weather systems (Ex. Hurricanes) • More heat waves • Changes in seasonal weather patterns that could cause droughts—crop failure

  14. The information doesn’t all agree yet, so we could wait to act… The issue is: What if we wait too long? There is a certainty in reducing our carbon footprint: It can’t hurt.

  15. What do you think we should do? Task: Write a 1 page journal response that address: 1. What we should do to reduce our carbon footprint • What are 5 things the average person could do • Do you think individuals should bother? 2. If you think sea level rise is something we should worry about and why/why not 3. If you think temperature rise is something we should worry about why/why not

  16. How you will be marked Main Goal: I want to see that you thought about it. 85-100: Answer all questions and give excellent detail. 70-85: Answer 2/3 of questions and give good detail. 60-70: Answer 2/3 of questions with some detail. 50-60: Minimum ½ page response that makes sense in relation to the topic questions.
