Title: Model lessons... Post by Grendel on May 19th, 2009 at 4:09pm
Climate guesses... otherwise known as modelling carries at all times disclaimers.
The confidence that can be placed on GCM climate projections is indicated by the disclaimers that the CSIRO always includes in its climate consultancy reports. For example:“This report relates to climate change scenarios based on computer modelling. Models involve simplifications of the real processes that are not fully understood. Accordingly, no responsibility will be accepted by CSIRO ... for the accuracy of forecasts or predictions inferred from this report or for any person’s interpretations, deductions, conclusions or actions in reliance on this report.” |

It's a bit like the human brain. We don't fully understand it, but we know a lot about it.
If we continue to drink alcohol, we're going to get drunk and we're not going to think too clearly. If we continue to burn fossil fuels, we're going to have a wide range of unwanted consequences, including global warming and ocean acidification. Blind Freddy can see that. We have a choice, and most of the world is at least starting to make the intelligent choice to limit emissions. There are at least two clear paths ahead. ![]() |

SCIENTIFIC COMPUTER MODELING METHOD 101
I'm a bit dismayed about how computer models have come to be more important than actual observations and so I offer a formal statement of the Scientific Computer Modeling Method. The Scientific Method 1. Observe a phenomenon carefully. 2. Develop a hypothesis that possibly explains the phenomenon. 3. Perform a test in an attempt to disprove or invalidate the hypothesis. If the hypothesis is disproven, return to steps 1 and 2. 4. A hypothesis that stubbornly refuses to be invalidated may be correct. Continue testing. The Scientific Computer Modeling Method 1. Observe a phenomenon carefully. 2. Develop a computer model that mimics the behavior of the phenomenon. 3. Select observations that conform to the model predictions and dismiss observations as of inadequate quality that conflict with the computer model. 4. In instances where all of the observations conflict with the model, "refine" the model with fudge factors to give a better match with pesky facts. Assert that these factors reveal fundamental processes previously unknown in association with the phenomenon. Under no circumstances willingly reveal your complete data sets, methods, or computer codes. 5. Upon achieving a model of incomprehensible complexity that still somewhat resembles the phenomenon, begin to issue to the popular media dire predictions of catastrophe that will occur as far in the future as possible, at least beyond your professional lifetime. 6. Continue to "refine" the model in order to maximize funding and the awarding of Nobel Prizes. 7. Dismiss as unqualified, ignorant, and conspiracy theorists all who offer criticisms of the model. Repeat steps 3 through 7 indefinitely. |

Do you think everything hinges on computer models ? It doesn't.
You think that just because there is some error (tolerance) in the predictions, that somehow, the future is going to be a bed of roses? Get your heads out of the sand. The science behind AGW is very basic, but of course the general population doesn't even understand basic science. Idiocracy is alive and well. Computers models designed in the late 80's successfully predicted the temperature variations encountered to date. Modern computer models are much more accurate than that. They are now in their 4th generation. You'll find a lot of total nonsense being spouted about computer models in your favourite sites. These sites that you enjoy reading are deliberate attempts to mislead people, and the gullible and non-scientific are being misled in droves if the state of the blogosphere is any gauge. For example - there is the claim that models are old - that they do not account for water vapour, that they rely on an iterative approach (what pjb was alluding to) or the biggest clanger of all: "These models fail because they rely on ONLY selecting CO2 as the cause of climate change." All of this is bunkum of course. The very first general circulation climate model that combined both oceanic and atmospheric processes was developed in the late 1960s at the NOAA Geophysical Fluid Dynamics Laboratory - even that took into account water vapour feedbacks. I'm no expert in modern climate modelling, but I recognise bs when I see it. My experience in climate modelling comes from the 90's, and even then , they had an enormous level of sophistication. |

I'm sorry the IPCCCCCCCCCCC changed their predictions based on the fact that the original modelling was hmmmm how can we be nice about this.... UPDATED. guess what they are still wrong.

Speaking of water vapour, Hydrologists came to conclusion that every second 7 cubic metres of water leaves Earth’s gravitational influence and is “lost in space”. Not much, but every little bit counts: 25,200 m3 an hour, 604,800 m3 a day, 220,903,200 m3 almost 221 cub. Km in an average year (365.25 days) and so on.

I'm not sure why uncertainty is such a difficult concept for some people to handle. If you shoot a gun, can you ever predict exactly what is going to happen? Does this mean we don't know enough about guns to manage the risks involved? None of the global warming policy that has been implemented hinges on being able to make accurate predictions. It is all about risk management. Less than perfect understanding of global climate systems is not a good reason to continue releasing GHG's on an industrial scale. In fact, the opposite is the case. There are appears to be some basic logical errors undermining Grendel's argument, assuming he is still pushing the same old barrow.
What exactly is your point Grendel? |
Title: Re: Model lessons... Post by Grendel on May 24th, 2009 at 10:44pm
Uncertainty does not equal error.
Basing a theory on a flawed premise is doomed to failure. Manipulation of parameters to achieve a desired result is not science. GiGo need I go on? |

So you still think a mysterious cabal of evil scientists is coercing the overwhelming majority of scientists, statisticians, and even politicians into endorsing their theory on climate change Grendel.
To what end is this conspiracy supposed to be working? How do they achieve the compliance, and secrecy of so many who have the knowledge to unmask their evil plot? Too many reputable people accept the facts as presented for your contentions to appear as anything more than the churlish rants of a denialist who cannot accept they may have chosen the wrong side, for political reasons. If you were honestly concerned about just seeing better science done, and greater understanding achieved, then that would be admirable, but you just are hoping for a chance to say, NYAH NYAH, I told you so, and you are so desperate for that chance that you latch onto every charlatan who has a new line of bull to spin. It is getting tiresome Grendel, unless you have some new information which will illuminate, rather than confuse, then you are just acting as a mindless spoiler. |

Wow! - and this takes as its source "Rocket Scientist's Journal" You don't have to go too far into that article to find inconsistencies: A computer run, for example, that assumes the natural forces are in equilibrium, and then calculates the effects of a slug of manmade CO2 that dissolves over the years is not valid. The run needs to be made with the natural outgassing process and anthropogenic emissions entering the atmosphere simultaneously to be circulated and absorbed through the process of the solubility of CO2 in water. Here he's demonstrating that he has absolutely no idea how computer models work. Total bunkum. That would not have a hope of getting past peer review because it is unadulterated twaddle. The worst part is that the author probably knows this but has an agenda, so he works on the premise that bs baffles brains. The last paragraph is about Cosmic Rays. Work done in 2007 proved that the Cosmic Ray activity has not shown any marked peaks. In short, this is deliberately obfuscating techno-twaddle. No serious journal would accept it for publication, which is probably why it can only be found in the "Rocket Scientist's Journal" (shades of Wayne's World) Treat it with the same respect as 'The moon landing was a hoax' or "Elvis is alive" sites. |

The predictions changed due to new data that showed that the situation was even worse than anticipated. Guess what? There is work going on right now that will appear in AR5. It's based on the fact that increasing methane emissions from Arctic Tundra are much higher than anticipated due to accelerated thawing. AR5 will find that AR4 was optimistic. That's how the scientific method works. As you get new information, you apply the new learnings and data. The basic hypothesis has always been sound. However, it's not like creative accounting where you make contingencies for things you don't know yet. The basic contention of that site that 'water feedbacks are negative' is farcical. It's the stuff that April Fools jokes are made of. |

Grendel - What? You didn't realise that methane was an important Greenhouse gas? You seriously need to study the basics. Here's an easy to understand site designed for kids. It has nice pictures and easy to understand text in many different primary colours. http://www.dnr.state.wi.us/org/caer/ce/eek/earth/air/global.htm The greenhouse gases The main gases that cause the greenhouse effect are: * water vapor * carbon dioxide, or CO2 * methane (!!!!!!!!!!!!!!! OMG !!!!!!!says Grendel) * nitrous oxide Some "greenhouse gases" occur naturally in the Earth’s atmosphere. Mate - The computer you're using now is a refinement of the computer you had previously (I'm guessing that you went for a newer model). The old one worked well perhaps, but the way of the world is to improve as we find out more. It's the same with everything in the world of science. The IPCC 4th Annual Report did not say that AR3 was invalid. It simply built on it with new data that was available. It did not change the basic conclusion. As we learn more about the magnitude of methane feedbacks, the original predictions will change - for the worse. It was expected, but you just can't invent data that isn't there yet. Climate modelling, like any science based discipline is continually adapting. Contrast that with the Climate Prognosticators like Richard Lindzen. He has held on to his Iris Effect model despite many studies that demonstrated time and time again that global water feedbacks are positive. There may be localised events which work the other way around, but the data indicates a climate sensitivity of 3 +/- 1.5 Celsius degrees for a doubling of CO2 concentration. The vast majority of papers fall well within that range. Where does Lindzen put it? He doesn't. No published paper on climate sensitivity. That's not science. It's pure advocacy, and an advocate will generally adopt a static unchangeable position. |

Lord Monckton’s paper reveals that –
The IPCC’s 2007 climate summary overstated CO2’s impact on temperature by 500-2000%; CO2 enrichment will add little more than 1 °F (0.6 °C) to global mean surface temperature by 2100; Not one of the three key variables whose product is climate sensitivity can be measured directly; The IPCC’s values for these key variables are taken from only four published papers, not 2,500; The IPCC’s values for each of the three variables, and hence for climate sensitivity, are overstated; “Global warming” halted ten years ago, and surface temperature has been falling for seven years; Not one of the computer models relied upon by the IPCC predicted so long and rapid a cooling; The IPCC inserted a table into the scientists’ draft, overstating the effect of ice-melt by 1000%; It was proved 50 years ago that predicting climate more than two weeks ahead is impossible; Mars, Jupiter, Neptune’s largest moon, and Pluto warmed at the same time as Earth warmed; In the past 70 years the Sun was more active than at almost any other time in the past 11,400 years. |

I wonder how many other people are blissfully ignorant of the fact that methane is a greenhouse gas with roughly 20 times the greenhouse gas potential of CO2? Some figures show 8 times, but it depends on the time scale - methane slowly breaks down in the atmosphere.

I'm sure anyone here who has read anything I've said... which according to Muso is totally irrelevant due to my lack of expertise and papers... would be quite aware of my position on climate change. Unlike yourself if I remember correctly you took 2 bob each way. Your support for the "cause" is risk assessment. Better to be safe just in case they are right. An insurance policy. The evidence does support my position... Muso is being a tad disingenuous as usual. The fact you don't understand is also completely understandable. I'm not and I'll repeat that in case it still hasn't sunk in... making any effort here to avoid anything, this topic is not one I'm very interested in, due to the lack of honesty from one side of the debate, but it does avoid the muslim crap. |

Well done Soren, you at least made a good point, although you have not supplied any data to support this yet. I'll try to answer you as well as I can. The CO2 concentration in the atmosphere and temperature are interdependent. Arrhenius demonstrated that increasing CO2 levels would increase temperature via the greenhouse effect way back at the beginning of the 20th century. This plot of CO2 versus temperature shows that current atmospheric CO2 levels are higher than they have been for 800,000 years: So something tells me we're not in Kansas any more, to quote Dorothy from the Wizard of Oz. To go much beyond that requires the use of proxies that are increasingly unreliable. However, work carried out in 2006-2007 show that the climate sensitivity has actually remained roughly about the same as far back as 420 Million years. Climate sensitivity constrained by CO concentrations over the past 420 million years Ref: Robert A. Berner, Jeffrey Park, Dana L. Royer Nature 446, 530-532 (29 March 2007) doi:10.1038/nature05699 Letter Here's an abstract of that study: http://www.nature.com/nature/journal/v446/n7135/full/nature05699.html I think what you are probably referring to is the end of the Ordovician period, 443 Million years ago, at which stage there was a period of glaciation. We really don't have enough reliable data on that period to conclude anything. While we have a reasonably good measure of solar activity over fairly recent times, we have very little idea of how 'hot' the sun was during that period. For all we know, the solar irradiance may have dropped resulting in glaciation. Ah, but you say - so how could this be when CO2 levels were so high? During geological time, CO2 levels have fluctuated enormously. Prior to the blooming of photosynthesising cyanobacteria (blue green algae), the atmospheric CO2 was in the two figure percent range, but of course, the sun was not as luminous back then. The main thing about these geological periods was that other conditions were different from today. With greater 'buffers' such as ocean life and in some cases, vast areas of rainforest, the actual CO2 to temperature relationship has varied somwhat. There have been periods within the last 420 million years where CO2 levels have changed sharply for different reasons, but generally these have been coincident with species extinction. Our best guide to climate sensitibity is the most recent geological periods. The main change in the last 150 years or so has been the dramatic reduction in tropical rainforest, which acts as a buffer, effectively removing excess CO2 and smoothing out any spikes. So it's important to compare apples with apples. |

I've provided an abstract of a study that shows consistent climate sensitivity over the last 420 Million years. In case you missed the connection, that implies a climate sensitivity of approximately 3 C deg for a doubling of CO2 concentration. The last 50 years at least has shown a 30% increase in CO2, and isotope ratios confirm that the source of the excess is substantially related to fossil fuel burning. On current projections, we're going to achieve doubling by around 2040, depending on how quickly the world reacts. I dunno - 420 Million years sounds pretty long-term to me. As far as the Ordivician glaciation is concerned - who knows ? All kinds of things can cause temperatures to plummet, including impact by a large meteorite, significant emissions of sulphur gases and particulates by extensive volcanic activity, some kind of glitch in solar output as I mentioned in the original post - and the list goes on. It makes more sense to attribute the glaciation to one of those causes that say 'let's just chuck 420 million years of data out the window because it doesn't support our case'. Don't you think? |
Title: Re: Model lessons... Post by muso on Jun 1st, 2009 at 10:31am
In fact, here's quite an old paper that may have some answers:
http://adsabs.harvard.edu/abs/1999PalOc..14..542P The analysis of the geologic record has revealed a question concerning how the Late Ordovician glaciation could have occurred simultaneously with high CO2 levels (10-18x). Sensitivity studies using a coupled atmosphere-ocean-sea ice model show that it is possible to maintain a permanent snow cover (which corresponds to 60% of all the glacial deposits found on Gondwana) under 10x CO2 levels, warm fall/cool spring orbital parameters, a 4.5% reduction in solar luminosity, a length of day of 21.5 hours, and an enhanced snow/sea ice albedo of 0.3. A cold summer orbit experiment with 10x CO2 and a reduced snow/sea ice albedo of 0.1 also sustains a permanent (albeit less extensive) snow cover. The geographic configuration of the Late Ordovician results in an up to ~42% increase in the global ocean poleward heat transport in the Southern Hemisphere relative to present-day and a significant asymmetry relative to the equator. In summary - the glaciation was probably driven mostly by the movements of continents toward the poles. So all you need to do is to shuffle the positions of the continents around - and hey presto! - Global Warming solved. ;) (If you speak to somebody regularly who is into the rapid migration of continental landmasses, maybe you could suggest it if He is willing to intervene.) |

When science magazine examined ALL, the published papers written on climate change in the previous 10 years, that is papers by real scientists, crackpots and non peer reviewed works were not counted, there were 928 of them. Out of those 75% agreed that man was having an impact on the changes, and the other 25% did not state an opinion about man's influence, but not one, zero, zip, nada, none, offered the opinion pushed by the denialists, that man has no impact on climate change.

As far as schizo goes, it is a bit like that, initially I tried to temper my responses because I did not want to be hypocritical, and post things which I may have to mod out, but I found it restricted me from being myself, and that was no fun for me, and devalued my ability to post my own opinions, so I have chosen to just go back to being myself, and if any are offended then I wil look at it, or ask Locutious or FD to, or whoever is Mod on the member run boards.

Muso does not want to do it any more, so we need a mod for this board now, and then you could delete my offending post, or edit it, or even ban me for flaming you.

I think we should try and be fair though, and try and contain our replies to the topic at hand, and stick to discussing that. The point about modelling being an imprecise system does have some merit, but to take that fact, and then try and use it to assert that we should ignore what we have learned from climate modelling, is a big stretch to make, even for denialists who only ever seem keen to add to confusing the issue, rather than offering any real contribution to the accumulated works and commonly accepted theories that climate scientists have developed. |

Models should be in support of primary, empirical evidence to illustrate that evidence. But in the political debate that sometimes goes under name of climate change debate, models are the sticks to beat sceptics over the head with. It is forever about some curve of annualised average or other. A model is always incomplete AND is always constructed with an answer or tendency in mind. Selecting what is 'relevant' is also deselecting what is irrelevant, so it is always already constructed with a mind already leaning towards a preconceived answer or trend. A sceptic like me is amused and irritated by the obliviousness of the model-toting doom-mongers to this inevitable epistemological bias that hangs around them and, like the smell of their own fart, repels everyone but themselves. |

Antarctic temperatures disagree with climate model predictions
COLUMBUS , Ohio – A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models. This comes soon after the latest report by the Intergovernmental Panel on Climate Change that strongly supports the conclusion that the Earth's climate as a whole is warming, largely due to human activity. It also follows a similar finding from last summer by the same research group that showed no increase in precipitation over Antarctica in the last 50 years. Most models predict that both precipitation and temperature will increase over Antarctica with a warming of the planet. David Bromwich, professor of professor of atmospheric sciences in the Department of Geography, and researcher with the Byrd Polar Research Center at Ohio State University, reported on this work at the annual meeting of the American Association for the Advancement of Science at San Francisco. "It's hard to see a global warming signal from the mainland of Antarctica right now," he said. "Part of the reason is that there is a lot of variability there. It's very hard in these polar latitudes to demonstrate a global warming signal. This is in marked contrast to the northern tip of the Antarctic Peninsula that is one of the most rapidly warming parts of the Earth." Bromwich says that the problem rises from several complications. The continent is vast, as large as the United States and Mexico combined. Only a small amount of detailed data is available – there are perhaps only 100 weather stations on that continent compared to the thousands spread across the U.S. and Europe . And the records that we have only date back a half-century. "The best we can say right now is that the climate models are somewhat inconsistent with the evidence that we have for the last 50 years from continental Antarctica . "We're looking for a small signal that represents the impact of human activity and it is hard to find it at the moment," he said. |

suggested reading... Fortunately, the most serious problem the climate models have (in my view) is one which is easily understood by the public. So, I'm going to make yet another attempt at explaining why the computerized climate models tracked by the U.N.'s Intergovernmental Panel on Climate Change (IPCC) - all 23 of them - predict too much warming for our future. The basic problem I am talking about has been peer reviewed and published by us, and so cannot be dismissed lightly. But this time I will use no graphs (!), and I will use only a single number (!!) which I promise will be a small one. Smile I will do this in three steps. First, I will use the example of a pot of water on the stove to demonstrate why the temperature of things (like the Earth) rises or falls. Secondly, I will describe why so many climate model "experts" believe that adding CO2 to the atmosphere will cause the climate system to warm by a large, possibly catastrophic amount. Finally, I will show how Mother Nature has fooled those climate experts into programming climate models to behave incorrectly. |

Well - partly right. East Antarctica would be the last place on Earth you'd expect to find significant increases in temperature right now, because it's a landmass located on the pole. Remember my previous post on Continental Drift during the late Ordovician? The "as predicted by many global climate models" bit is an exaggeration. Most of the new climate models (fourth generation) are better now at polar latitudes than they were in the past. The Antarctic peninsula however, has shown some of the biggest increases in temperature in the world. Remember April this year? The Larsen Iceshelf? http://earthobservatory.nasa.gov/IOTD/view.php?id=2288 Over the last five years, the shelf has lost a total of 5,700 square kilometers and is now about 40 percent the size of its previous minimum stable extent. |

The tiny fraction of carbon dioxide in the atmosphere increased through the twentieth century. And yet, during that time, global average temperatures rose till about 1940, fell till about 1975, rose again till 1998, and then dropped away again. It is not surprising, then, that despite claims “the science is settled,” thousands of scientists disagree with forecasts of dangerous manmade global warming.
History again provides useful guidance. We've already covered the very imaginative interpretation of this particular chestnut. Why would global temperatures rise and fall??? Have a think about it. While you're thinking about it, take a look at this site. It might just give you a hint. Look carefully of the graph of solar irradiance. If you're actually going to listen this time, Grendel, I'll even explain how it was derived - but I doubt if you're interested. Yes - when the "sun" is hot, the temperatures go up. When the "sun" is not and the temperatures still go up - that's the time you need to sit up and take notice. Why do you think the red curve follows the blue curve so well ? http://www.mps.mpg.de/en/projekte/sun-climate/ Hey - and I'll tell you something else - It's colder at night than it is during the day. The CO2 level in the atmosphere is pretty much the same during day and night, so why do you suppose that might be???? hmmm? |

Humans must have more than 16% O2 to be able to live so there is only about 5% of usable Oxygen for us. |

Happy - yes, atmospheric oxygen is slowly depleting, but we have far more imminent problems than that.
People can go on about geological time and climate variations until the cows come home. The whole issue about sorting out this mess is not really about trees and whales and endangered species and all the feel-good deep green environmental issues. It's more about the fact that we have a precariously high global population, and that we don't have enough time to adapt to higher temperatures, decreased calcification rates in major food chain ocean species, reduced water supply from non-polar glaciers, impact on crops yields from higher average temperatures and the rest. The imminent crisis is about averting human catastrophe on a major scale. It's not really about saving nice fluffy polar bears. You might say - ok let's reduce world population. Good idea - how? The main carbon emitters are in the developed world. The main victims will initially be in poorer countries. |
