Open Question: what is the greenhouse effect (see picture)?

Open Question: Which of these do you believe, and what would it take to get you to believe the others?

I've asked variations of this before, but this is kind of combining 2 questions. Ok, here's a numbered list of everything I can think of that at least some people believe about AGW: 1. The planet is warming, and has been for the past ~ century 2. The planet has not been warming unusually over the past ~ century, any warming we have seen is simply us coming out of the last ice age 3. The warming in 1. is primarily due to human influence, primarily human emissions of CO2 (and to a lesser extent methane and N2O) 4. The warming in 1. is entirely, or at least primarily, due to natural factors 5. The warming in 1. is likely to, on average, be harmful for humans and natural systems 6. The warming in 1. is likely to, on average, be beneficial for humans and natural systems 7. The planet has both warmed and cooled significantly in the past 8. Present warming is historically unusual 9. The planet is likely to continue to warm, probably at even faster rates if we do not take action to curb human greenhouse gas emissions 10. AGW is a hoax, a conspiracy, or otherwise blatantly false 11. AGW is going to make the planet unlivable, cause the extinction of the human race, or the like, at least if we don't take action. 12. The problems in 11. are likely to happen within the next 2-3 decades 13. The problems in 11. will only happen if AGW remains unchecked for the next century or so. 14. AGW is real, but has stopped. 15. Taking action against AGW can be done in a way that does not cause economic collapse 16. Taking action against AGW will invariably destroy the economy and/or send us back to pre-1900s tech. 17. AGW is real, but trivial, most temperature variation is due to natural causes and there is not a significant anthropogenic long-term warming trend 18. Ocean acidification is real and harmful 19. Ocean acidification is not real 20. Ocean acidification is harmless I think that pretty much covers it. If there's any major viewpoints/ideas I missed, feel free to add them as additional numbers. So. 1. What things from this list do you believe? 2. What would it take to get you to believe some or all of the things from this list that you don't currently believe? (if there are some things that would require something like a Matrix-style reality-is-not-real revelation or the like for you to believe, feel free to either skip them, or just list them as "not going to happen" or the like...) I believe 1, 3, 5, 7-9, 11, 13, 15, and 18. And not much could get me to believe 2, 10, 12, or 19. I can think of plausible evidence that would convince me of the rest, but haven't seen any such evidence. And if you just want to address one or 2 "I would believe X if..."s, that would still be great. As to why, Dook? Mostly that I anticipate getting a lot of sensible answers, and a lot of absurd answers, and I think we both know which side will produce most of which... Tao: an example of how I'd want the second part answered: I would believe 14. if temperature records leveled off or started to decline, and this leveling off or decline lasted for 30 years. I'd believe 4. if scientists identified both a reason that anthropogenic greenhouse gasses *weren't* causing warming, *and* a natural factor that tracks the warming we've seen that *does* cause warming, and provided compelling evidence of both.

Open Question: When Republicans speak of deregulation of industry, does anyone have an idea what the hell they are talking?

about? To be fair, they are specific about not wanting to regulate greenhouse gases and do not want the Wall Street Bankers to be bothered. But aside from that, I have trouble getting my head around what they want. Do they want to deregulate the window cleaning industry to allow people to work 6 stories in the air with no safety harness? Do they want to do away with the expensive burden of providing hard hats to construction workers? Do we stop requiring the breaks on 18 wheel trucks to be inspected? Do we stop the expensive practice of labeling and inspecting food? Will we allow Agent Orange to be used on weeds around school houses? What in the hell are they all talking about?

Open Question: Is it that Republicans want no regulation on industry or do they want "sensible" regulations?

They seem to shift their stance pretty often. Of course anyone who would agree to any regulation would want the regulation to be "sensible". What sort of idiot would want a "nonsense" regulation? But what is "sensible"? Republicans don't believe that greenhouse gas emissions matter. But non-republicans and the rest of the world disagrees with them. So how do we determine what is sensible? Sensible to whom? Most "Liberals" think that Too Big To Fail Banks should be trusted with our economy and should be highly regulated or broken up by regulations. Republicans violently disagree. Where do we find a "sensible" regulation, assuming you believe in any regulation?

Version number. Name of institution/organization affiliated with the site (sponsor or publisher), date of resource creation (if available). Medium of publication. Date of access. I have no idea how to find most of that. Please help?

Open Question: advantages of greenhouse effect?

i need to know advantages of the greenhouse effect , hope someone can help

Open Question: Which of the following statements is NOT accurate?

a) greater use of coal would reduce greenhouse gas emissions and make the US dependent on imported fuel b) greater use of nuclear power would reduce greenhouse gas emission and make the US less dependent on imported energy sources, but nuclear power is expensive and it is unclear what to do with the highly radioactive waste it produces c)hydrogen fuel cells could produce electricity without greenhouse gas emissions using domestic sources of hydrogen, but the electricity produce would be very expensive using current technology d)solar and wind power generators produce inexpensive electricity without greenhouse gas emissions and they do not require imported fuel, but the cost of building the electricity generation and distribution infrastructure is very expensive. e) a carbon dioxide cap and trade system could theoretically produce considerable reductions in greenhouse gas emissions, but success depends on disputed details such ad how permits would be distributed and the extent to which offsets could be used

Open Question: The US has 200 million cars, each going on average 12000 miles in a year. The current fleet average is 30 mile?

The US has 200 million cars, each going on average 12000 miles in a year. The current fleet average is 30 miles of gas per gallon. The goal here is to estimate how much we can save in greenhouse gases if we switch to electric cars. a) Estimate the net carbon emissions in Gtonnes of C in CO2 per year for current American cars with the fleet average. b) Now assume we switch all those to Nissan Leafs. The Leaf has a Li-ion battery pack that can store 24 KW-hrs of electricity, and gets a range of 100 mi per charge. Neglecting transmission losses, how many kW-HRs of electricity would you need to generate each year for the American cars? c) Now approximating the US electricity generation as 60% Coal (15 mJ/kg, chem. formula CH) burning at 35% efficiency, estimate the net GTonnes of CO2 emitted by the hypothetical purely electric fleet. This is about right for Ohio.
