1. Global Warming

2. CO 2 vs. Global Temperature

3. Ocean Temperatures

4. Melting Glaciers

5. Man-Made Sources of CO 2 Fossil Fuels Coal 44% Oil 36% Natural Gas 20% Photosynthesis 2n CO 2 + 2n H 2 O + photons → 2(CH 2 O) n + 2n O 2 Excessive use fossil fuels Concrete Production (5%) Chopping down trees

6. Man-Made Sources of CO 2 How much CO 2 do you create / year from your – Car? – Breathing? Both are forms of respiration (combustion)

7. Car Emissions I use 10 gallons / week – 3.78541 L = 1 gallon – 52 weeks = 1 year – 0.703 g octane = 1 mL octane – 114.23 g octane = 1 mole octane – 44 g CO 2 = 1 mole CO 2

8. Breathing Emissions Need to perform an experiment How much CO 2 do we exhale per minute? Assume that if we exhale into water all the CO 2 makes carbonic acid Figure out how much NaOH is needed to neutralize the acid
