The document discusses global warming, defining key terms like greenhouse effect, carbon sinks, and global warming itself. It highlights causes of climate change, including carbon dioxide emissions from fossil fuel combustion and methane emissions from livestock, along with the adverse effects such as sea level rise, severe weather, and biodiversity loss. It concludes with solutions for reducing emissions, including tips for personal transportation, energy efficiency, and dietary changes.

1. Global Warming:the 411

2. First, some climate change terminology:Greenhouse Effect: The insulating effect of atmospheric greenhouse gases (e.g., water vapour, carbon dioxide, methane, etc.) that keeps the Earth's temperature about 15 º warmer than it would be otherwise.Greenhouse Gas (GHG): Any gas that contributes to the "greenhouse effect."Global Warming: The progressive rise of the Earth's average surface temperature caused by increased concentrations of GHGs in the atmosphere.Carbon Sinks: Processes that remove more carbon dioxide from the atmosphere than they release. Both the terrestrial biosphere and oceans can act as carbon sinks.Positive feedback loop: natural processes that can amplify the magnitude of the warming eg, as temperatures rise, ice melts, more dark sea water is exposed, absorbing more heat, causing more ice to melt…

5. #1 CausesSo who, or what is responsible?

6. Carbon Dioxide

7. burn baby burn...CO2 is released when ever fossil fuels are burned……and they’re burned a lot!

8. Burned forPower generationCoal

10. Moving us and our stuff around the globe…and for getting more oil, coal and natural gas out of the groundBurned for

11. Fun Fact!there are no fewer than 4,000 aircraft in the air at any time over the U.S.

12. Causes continued…So who, or what else is responsible?I don’t even own a car!

13. Or more accurately, the people who eat them…I hope this place has good plumbing!

14. Fun Fact:methanebeef cattle account for a whopping 70% of all livestock methane emissions!

15. Other sources of methane:a.k.a. cow burps!

16. Fun Fact!There are billions of tonnes of methane trapped in the permafrostandMethane is 20-30 times more powerful than CO2 at trapping heat!

17. positive feedback loop:

19. Water - sea level rise, coastal flooding, mass evacuations - fresh water shortage (rivers and lakes) - ocean water acidification (base of the food chain) - Thermohaline circulation shut down - coral bleaching

21. A pteropod shell exposed to carbonate ion-depleted seawater with acid levels set to the pH of ocean water expected in 2100. The shell dissolved after 45 days. Rising CO2 levels in the atmosphere, directly correspond to increasing acidity of seawater.

22. Severe weather - increasing in frequency and severity.

23. DiseaseMalaria

24. Habitat loss & Species ExtinctionAll of these animalsneed arctic iceto survive…

25. …and it’s melting fast.

31. Solutions!…yes, something can be done !

33. Tips for Cutting Automobile EmissionsTake it easy: Aggressive driving wastes fuel. Driving like a moron can burn an extra 125 gallons of gas per year!Don't idle: Idling for more than 10 seconds uses more gas than restarting your car. A/C: Air conditioning can decrease your fuel efficiency by as much as 12% in stop-and-go traffic, so consider cracking the windows. Keep up the pressure: Low tire pressure wastes over two million gallons of gasoline in the U. S.— every day!Skipthe drive thru! – instead of letting your car run as you inch toward the pick-up window…turn it off, get out, and pick it up yourself

34. A gas powered lawn mower running for 1 hour emits as much pollution as driving 1000 km in a 1992 model automobile

35. Zero CO2Zero V.O.C.s(volatile organic compounds…a.k.a. pollution)

36. Half a million trees would be spared if every U.S. household replaced a 500-sheet roll of tree fibre toilet paper with one made from recycled paper…so quit flushing trees down the toilet!

37. Air Dry Your Clothes

38. Line-dry your clothes in the spring and summer instead of using the dryer. Save 700 lbs. of carbon dioxide and $75 per year.

39. fun fact!Seventy percent of the levelled rain forest in the Amazon is used to raise animals for meat consumption….so eat less meat!

40. Solar power!Hours for Earth to receive the same energy from the sun as humans consume in a year: 1
