Today International climate treaties

Today International climate treaties. Montreal and CFC’s Kyoto and CO 2 FCQ’s All power point images are only for the exclusive use of Phys3070/Envs3070 Spring term 2014. A good example:. The “Ozone Hole” is detected, with less O 3 allowing harmful UV to the surface of the earth.

  1. TodayInternational climate treaties Montreal and CFC’s Kyoto and CO2 FCQ’s All power point images are only for the exclusive use of Phys3070/Envs3070 Spring term 2014

  2. A good example: • The “Ozone Hole” is detected, with less O3 allowing harmful UV to the surface of the earth. • Lab work shows that CFC’s can catalyze O3 destruction • Many commercial uses were releasing CFC’s • Much of the world agreed to stop producing CFC’s—The Montreal Protocol

  3. CFC’s substitutes In the ozone layer

  4. BAU

  5. BAU

  6. Why did it work? Understood Solution obvious—ban CFC’s No cost--substitutes

  7. Is that CO2 you see?

  8. The Kyoto Protocol

  9. The players Annex 1-developed Annex 1 (Economies in Transition)-FSU Annex 2-developing

  10. Kyoto states

  11. USA AEO = Annual Energy Outlook of the EIA.gov

  12. Last day, Friday May 2 What is to be done? Please create drafts of a single specific step to improve our energy/environment future, large or small, that you would take as world dictator. Send to me, and volunteer to make a five minute presentation on our last day. (double extra credit if selected!)

  13. Next week Monday-- HW #10 is due Population and other exponentials. Question? Is human population destined to follow a Hubbert curve?? Wednesday—The few important components of our energy and environment future Friday—Student solutions Wednesday May 7, office hours 9-5. FINAL –Wednesday May 7, 7:30-10 PM

  14. Homework 10 due at 0900 Monday April 28, 2014 1. If the EPA issues cap and trade permits or adds a carbon tax, spewers of CO2 will have to pay $40/ ton (English short ton=2000 pounds) of CO2. (5) How much is this in terms of dollars per ton of carbon in the CO2? This is just another way to make the statement. (10) If our local Valmont plant got all of its power of 312 MWe from burning coal at 30% efficiency, how many tons of coal are burned each hour? (5) If that coal is 70% carbon, how many tons of CO2 would be emitted each hour? (5) What would the EPA charge for emitting that much CO2? (5) Final part—How much would you the customer have to pay per kW-hr for that CO2 from coal?

  15. 2. (5) Why would it be cheaper for you if gas, not coal, were burned? You need not be quantitative. • 3.(10) US electricity generation from coal now emits 2600 million tons of CO2 per year. How much would the EPA collect each year from that $40/ton? Now—suggest something useful and relevant to climate change for that money. • 4. (10) What problem has the Montreal Convention fixed? This happened easily and quickly. Why? • (useful context—and why was meeting the Kyoto Protocol so hard?)
