Thank you, Into the Night, for confirming that the discussion did not start with me demanding a source of data concerning Atlantic hurricanes. You were lying. If you could just stop lying, we might be able to have a sensible conversation. By the way, didn't the first rule for your Data Mine demand that posters name the sources of their data? Why are you so concerned that I am trying to enforce your rule? Edited on 25-10-2015 21:49 |

I did not, as you claimed, start the discussion by demanding a source of data concerning Atlantic hurricanes. It's simply not true. You were lying. As a matter of fact, the initial evidence I cited to support my contention that the frequency of intense storms was increasing was this paper: Changes in Tropical Cyclone Number, Duration, and Intensity in a Warming Environment Other papers supporting this view are, for example: The increasing intensity of the strongest tropical cyclones Increasing destructiveness of tropical cyclones over the past 30 years Trend Analysis with a New Global Record of Tropical Cyclone Intensity These papers confirm that the intensity (though not the frequency) of tropical cyclones appears to be increasing, and that this is likely due to the higher ocean surface temperatures observed over the last few decades.

You could even do experiments in your back yard to get a lot of the figures. The degree to which they can be changed by CO2 rises is where the debate is. The paper that was cited which refuted a 1905(? something like that) paper said that there was no limit to the potential heating effect of CO2. I am not aware that this is at all mainstream. It is certainly not the view presented by the IPCC. So if that is the case the whole model of GW needs to be redone. It will have to explain why such a run away situation has never happened before in addition to actually having some sort of basic data to support it. Tall order. |

This position puts the onus totally onto the Ecco-communists to explain why we need to hit the panic button. The energy budget diagram is not contestable because something of that sort happens. It's just a diagram of what happens. We can measure the energy of the sun's rays in space (not personally but..). We can measure the energy of the sun's rays in our back yard. If you really want to do this wait for a sunny day then get a black bucket of water, allow it to reach the same temperature as the surroundings, then put it into the sunshine. Have a cover over it so that it cannot evaporate, maybe a black 1 gallon container with a screw top would be best, maybe an ex-Castrol oil thingy... Then test how it warms up, how long it takes etc. If you know it's heat capacity and the efficency of the amount of heat energy it absorbs you can work out the strength of the sun's rays in Watts per square meter. You will get an answer. To get another answer do it on the top of a mountain so that you have less cloud and stuff and this will allow you to work out how the cloud effects the result. Keep doing it and you will eventually get a decent understanding of the effects of atmosphere on the sunshine... What law of thermodynamics do you see as being violated in the diagram? If the amount of heat coming in is more than the amount of heat going out the earth will warm up a bit. The oceans will take a lot of heating. Of course the degree of accuracy of the satelite measuring the out-going radient heat energy has to be very dependable and could easily be getting a very slightly wrong number.... Or not seeing the occaisional hot spot..... Or having it's data corrected... |

I'm fine with your acceptance of the diagram for the purposes of debating a particular issue depitced therein. However the diagram is completely contestable because that is not what happens. There needs to be two top level arrows, like the bottom line numbers on a balance sheet, ...one arrow showing the total energy entering earth's atmosphere and one arrow showing total energy leaving earth's atmosphere, and those two numbers must match. We'll call that the balance value. All the breakdown arrows spawning from the one incoming solar arrow obviously must add up to the balance value. Similarly all the component arrows combining into the outgoing arrow must add to the balance value. Tim the plumber wrote: [color=blue] We can measure the energy of the sun's rays in our back yard.. Yes. Granted. My main focus is on the top level numbers (incoming vs. outgoing) not matching.

The effects of global warming will be, if the IPCC is right, noticable. They just won't be bad. They will in fact be good. I can see no real likelyhood of any significant actual down side. The wrost thing I have so far come across is if you have built your house in some African desert close to the river that has not flowed for 20 years the increased rainfall that will fill the river will probably wash your shack away. You will have your choice of highly fertile land to go and farm though. The energy budget for the surface of the earth can be out of balance. If it is there is more heat going in than coming out which will cause the place to warm up. If you measure the heat coming out of a kettle when it is warming up it is less than the 2kW of electricity going in untill it hits boiling. Then you will burn your hand if you put it in front of the spout. Often alarmists talk about Zeta Joules of energy going into the oceans. I have come across 1 who knew what a zeta joule is and was able to understand what happens when it goes into the oceans. That a Zeta joul is 10 to the 21 Joules sunds vast. A Joule is the amount of energy it would take to heat 1mg of a substance with a specific heat capacity of 1, 1 degree c. There are 1000 mg in a liter, 1000 liters in a cubic meter of water or tonne, same thing and water has a heat capacity of 4.2. Each cubic meter of water needs 4.2 x 10^6 Joules per degree to heat up. There are 1,000,000 square meters in a square kilometer and generally they talk about a depth of 700m, so 7 x 10^8. Multiplied by the 4.2 x 10^6 is 3 x 10^14. The world's oceans cover 360,000,000 square Km. x the above is 1 x 10^23 Joules needed to heat the oceans by 1 degree. So each Zeta Joule will cause about 1/100th of a degree of warming. The best data we can get for the temperature of the worlds oceans is nowhere near accurate enough to get this kind of precision and I don't actually care if it did manage it. It is going to take a heck of a lot of Zetas to cause any change anybody will notice. |

Tim the plumber wrote: I wonder if you are even getting 1/100th of a degree of warming. Here's why: While you can certainly measure the amount of energy reaching the surface of the Earth in your back yard, quite a bit of that energy does not go into heating anything. It just reflects back out again. How much reflects depends on the color of the surface it is striking and it's texture. Ocean water is quite reflective. The color of the water varies also. Even more so on land. Is it possible to get an accurate idea at all of how much actual energy is being absorbed by the Earth when reflectivity is constantly changing and nonuniform like it is? Even with measured data showing the level of energy arriving from the sun? Edited on 27-10-2015 00:02 |

IB, When the sun comes up at dawn your back yard is cold. The energy going out of it is higher than the energy coming in, it is still cooling. This is reversed as soon as the sun gets high enough in the sky for the energy coming in from sunshine to be higher than the energy going out. Then it starts to warm up. It is soaking up heat energy. Eventually the energy balance of the earth must be in equilibrium but this is only true over long periods. It can constantly warm and cool. You say that the only variable in the whole system is the sun's input. I don't know if that is true. My feeling is probably 5% agree with you 1% agree that there is a GW effect and 94% I don't know. Thus I cannot really debate the point. So I must use the accepted "consensus" to work with. That would be the IPCC's figures which are so wide that almost any possibility is covered. But looking at the worste case scenario I see nothing to worry about. Whilst it would be noticable it would be noticable in a small way. And a nice way. Not tropical paridise but a tiny step towards it. Like moving 150 miles towards the equator. Slightly warmer. Mostly of accademic interest. On to the absorption rate of oceans; The degree by which a beach side sea becomes warmer during the day is fairly predictable. So the albedo, the degree of reflectivity, of the sea moust be fairly predictable. So you can work out the amount of heating it is doing etc.... |

If I were reading a book, I would appreciate this type of first person perspective. However, we are talking about the planet. Pan out all the way to the view of the sun heating the earth. Let's use this perspective since differing relative positions on the planet's surface matter not (or do you prefer "naught"?). We have the side that is facing the sun and the side that is not facing the sun. It does not matter whether the planet is rotating or not rotating. Your "from the back yard" perspective involving night and day confuses the issue. The sun is not turning off, turning on, turning off, turning on, etc. So you have the sun heating the earth. Exactly the same amount of solar energy that is absorbed by planet earth is radiated away by planet earth. If you change the composition of the atmosphere, the earth will still radiate away exactly the amount it is absorbing. The composition of the atmosphere is meaningless. Albedo is also meaningless. If you do something to planet earth such that it reflects more solar energy away and ends up absorbing less solar energy, then earth will radiate away less solar energy. The two will be equivalent. So, how can earth's temperature increase? Well, the earth's orbital distance from the sun isn't going to change noticeably anytime soon. We can't make the atmosphere any more transparent that it is. I don't forsee the atmosphere doubling anytime soon. All that's left is an increase in solar output. That increases the earth's temperature which increases the earth's thermal radiation to exactly match the amount of absorbed energy. Remember when the topic of "greenhouse effect" arises that temperature is the only determinant in the amount of thermal radiation. Many will try to tell you that temperature is somehow increased by decreasing the rate of thermal emission. Not possible. If the temperature increases then the rate of thermal radiation will increase...to ensure the outgoing energy matches the incoming.

If that is your chosen church the great! If you have found a religion that affords you comfort, then all the power to you. However, if you are also trying to convince yourself that your religion is science, then your happiness will rest in your ability to delude yourself. Tim the plumber wrote: But looking at the worste case scenario I see nothing to worry about. Right, your Global Warming faith certainly has a much more benign "worst case" than the catastrophist denomination's.

The argument from the "standard" model is that high energy EM gets through the atmosphere better than th elower energy IR that the earth radiates away so if that is true then I can see there can be a greenhous eeffect. It si after all similar to how the glass in agreenhouse works. I don't know enough to debate the point as I am unable to show any evidence for or against it. I don't know. If it's a statement of faith to rely on science to be honest and as right as they can be then OK. But this is accepted and long standing. It could be wrong I have seen a paper which seemed strong to me which argued the case for the temperature of the surface of th earth not needing any such greenhouse effect to explain it's temperature but I am not able to really have astrong view on it as it's mostly beyond me. But if you accept the IPCC's figures, just for the purpose of moving the argument on, then there needs to be no response at all.

It si after all similar to how the glass in agreenhouse works. Whatever energy "gets through" and which energy "bounces around" and which energy "powers through the turns" is completely irrelevant. The only question of relevance is "How much incoming energy is absorbed?" ...by the atmosphere, by the oceans, by the surface, ...add up all the absorbed energy. That's the amount that radiates away and is the amount that determines the temperature. Any incoming energy that is not absorbed doesn't factor into the equation. Any incoming energy that changes form to thermal energy and then to a different frequency of EM will still amount to the same amount of energy (conservation of energy).

IB, For some reason the average temperature of the moon is very much lower than the earth. If you can account for that then you have a model which will deserve a good look at. I have seen such a model/paper which did that without needing the greenhouse effect. That's why I am 5% swayed in that direction. The generally accepted model needs it though. That's why I am 1% swayed in that direction. Perhaps the reason that I am more in the direction of there being no greenhouse effect is my confirmation bias or just that it was the one I read last. But I am 94% of the opinion that I am unable to debate the finer points of it at all. But then I don't think it matters much in a political policy sense which I think is far more important. I think that political policy should look at the IPCC's over hyped and stretched upwards numbers and have a little think about just how inconsequential they are. |

If you use an IR camera you can measure the heat of the moon or any other heat emitting object at a distance. This is easy and accurate to a level that is much better than 1 degree. Given that I put myself at 94% don't know about the greenhouse effect I don't think I can be accused of being religious about it. You however KNOW about it despite not being able to present any evidence about it. That is religious. I care only in a accademic sense about the effects of increased CO2 if they are not going to be noticable. If care a lot about public policy.

Tim the plumber wrote: Given that I put myself at 94% don't know about the greenhouse effect I don't think I can be accused of being religious about it. You most certainly can. You're playing semantic games. Belief is not what you "know" but rather what you "believe." The concept of God is completely unfalsifiable, hence no one can literally know whether God exists, but that doesn't prevent many millions of people from holding a very strong belief in such. There's no way you can "know" anything about the unfalsifiable Global Warming dogma in which you believe. There is nothing wrong with your belief beyond your own irritation at it being correctly called a faith. I hope you realize that if you are bothered by the true nature of your faith being revealed then you probably shouldn't be reading posts in a forum discussing all aspects of Global Warming. If you don't mind me asking a question, you have me a tad confused. Why do you, on the one hand, announce that you don't know enough math and science to debate a particular point, but then get all pissy when someone like me simply explains that point to you?

@Totototo - I've always seen religion and science as two sides of the same coin. Both are trying to interpret the world we live in. Religion approaches it by attributing everything to a higher power (the unknown). Science approaches it by attributing everything to natural causes (the known or yet to be known). In some ways, religion was our first attempt at scratching out organized thought about our surroundings and, in that sense, can be considered a proto-science. Unfortunately, by today's standards, the people who created the foundations of our major religions (the Torah, the Koran, the Bible, etc.) had, by today's standards, about a third grade education. Now, I think we can do better than that, and that's why I prefer science, though I stay conscious of religion. The 2015 M2C2 (Global 9/11) Denialist Troll Awards

Absorption of infrared energy generally takes place during the day. That's when there is so much of it available from the sun. The effect reduces the warming of the surface by preventing that energy from ever reaching the surface in the first place. Absorption doesn't just sit there as electromagnetic energy. It is the conversion of electromagnetic energy into mechanical energy in the form of vibrating molecules. A vibrating molecule does lose some of it's energy back into electromagnetic form again, but the frequency is changed significantly. Most of that energy is in the form of radio waves, with some extending up into the low infrared again (making it detectable by an infrared scanner). Most of the energy, though, stays with the molecule...until night. As surrounding conditions cool, this energy in such a molecule can now flow away. The difference of energy is now outward, not inward. The grand upshot is cooler days and warmer nights...in other words, a narrowing of temperature swing. The molecule has added no energy, but it has helped to moderate it. This effect is true for all matter in the atmosphere, regardless of the actual substance. The only difference is that some components are a bit more inclined to absorption of certain frequencies than others. It is this difference that is used as the principle behind Mauna Loa's instrumentation. Until we went to the Moon, we had no real idea of it's surface temperature. The only information we had was measuring the temperature on spacecraft in orbit. High altitude balloons gave us a vague idea of that, so we could prepare spacecraft that could handle the peak temperatures anticipated. Unmanned rockets helped to confirm this before anyone sent a man up for the first time. Stars are high energy objects. The color of light they produce is shifted toward red, but they are still in the visible range. This gives us a fairly good idea of their surface temperature. It is more accurate in space without the problems of a fluid atmosphere messing with the measurements, but the atmosphere is less of a problem for such objects. |
