I non intelligo, so it hasn't been falsified. That means it's not up to the mark ... in some way. Which ways are these, any idea? An interesting remark there about "you can't falsify the god of code". Is this a hypothesis you're aware of? Where does it apply? How do you know it's unfalsifiable? God of code, hmmmmm, you mean the God of religion? Sorry, I'm terribly confused at the moment.
StringJunky Posted July 20 Posted July 20 1 hour ago, Agent Smith said: Why would NASA use it? I mean it works as a simulation, but many (eminent?) scientists have criticized late Lovelock for what they probably think is jumping to conclusions. Is there evidence that earth is also a Daisy World, albeit more complex? Has The Gaia Hypothesis been falsified? Daisy world describes albedo, which should be pretty straightforward. It's a model. That first video was from NASA. To my knowledge it has not been falsified. Bear in mind I'm just someone on the internet.

Didn't religion hold sway over much of human history? Verum, that science simply compounded the problem by improving efficiency, but in the past half-century science has at least identified the problem, though it seems to be out of its depth when it comes to solutions. You see a link between religion and TGH? Someone did mention it's kinda sorta popular with NewAgeists. Yes, we can continue to live here ... that's a plus in my book, but I don't quite get why you emphasize language. Do you wish to discuss TGH from a linguistic POV? I wouldn't know where to start.

To my knowledge it has not been falsified. Bear in mind I'm just someone on the internet. I have already complimented you on introducing DaisyWorld. But please realise its limitations. Yes Albedo is a very important factor, particularly as the ice sheets grow or recede. which might lead to an acceleration of change. But it is not the only factor and rarely the controlling factor. I found the video interesting, but NASA did not offer their mathematics. From their explanation I can deduce that they are using some kind of Volterra (predator-prey) equation, which is known to have chaotic features (sudden jumps and bifurcations in its solutions) in its phase space. It also depends upon where those ice sheets are (as well as their elevation) since the available insolation energy varies with position on the Earth. A further important effect is that of energy transport , which again is greatly affected by the disposition of the land masses. And the distribution of land masses is controlled by plate tectonics. Quote The ocean exerts a very strong control over global climate. ... During Oligocene times ( 38 to million years ago) Australia became separated from Antarctica, while the land link between South America and the Antarctic Peninsula was also broken. these events lead to a ggreat change in the oceanic circulation of the southern hemisphere; for the first time ocean currents were able to circulate freely around the Antarctic Continent, linking the waters of the Pacific, Indian and South Atlantic oceans in the process. ... The winters of the World Brian John (Durham University) p 47 So from the very earliest to the most recent times Very different regimes of atmouspheric pressure, temperature and composition have prevailed or persisted for long periods of time. During these periods quite different land and oceanic conditions pertained in respect of disposition of land and ice over the globe. Also quite different regimes of energy transport (ocean currents and atmouspheric winds) pertained. So it is not suprising that different forms of life appeared and disappeared over time. Two things follow from this. Our own particular set of circumstances which do indeed constitute a stable state and embody several mechanisms for resisting change (Gaia) have only persisted for a total of a few tens of millions of years so it cannot be said that The Gaia State is ideal, natural, normal for the Earth (or not) We can say that it is very convenient for our form of Life. Since the earliest forms of life did not use or generate oxygen through the chemistry Agent Smith has outlined and even those later ones that did we largely wiped out by the planetary environment 250 million years ago we cannot say that evolution had proceeded in a simple linear fashion to ourselves.

But it just does not happen to be in effect on Earth. 2 NASA's Daisyworld states explicitily that it only addresses one single factor Your idea of balance requires a multifactorial analysis. Gaia acknowledges this and offers a multifactorial balance. However I have also noted that has also been extended by mystical and (semi) religeous groups so if you are not going to use Lovelock's original you need to make that clear. Of further interest I pointed out that the original statement is basically a restatement of Lyell's Uniformitarianism. It is worth noting that, as with Gaia, the original "uniformity" (lyell never used the word uniformitarianism) has been hijacked by later workers for their own ends so I am posting the original 4 postulates. Gaia is a transcription of postulate 4 which I have starred. Note the first two postulates are the same as those used by physicists Newton and Einstein in their theories, that both space and time are homogeneous and istropic. 1 hour ago, dimreepr said: I think you have gone off-piste with your interpretation of balance here, you're conflating different definitions. I'm glad you pointed this out +1 I brings out what I have been trying to say that several terms used here are subject to contextual differences of definition.

I've been watching your comments on feedback with increasing interest, and you raise important points a) because there is an awful lot of misunderstanding mixed in amongst the loose terminology, and b) because it gets really complicated really quickly. Loosely, feedback occurs whenever a process output is fed back into the input thereby modifying the subsequent output. However, there are some major provisos here, particularly with regard to causal links. 'Feedback' cannot as of current scientific concensus refer to the transfer of anything back to an earlier point in time. It therefore is not a transfer from an output back into the input that created that output. It is a transfer from an output phase into a subsequent input phase. Some examples may help explain: I'm glad you noticed this one. also +1 So what is the popular decision ? Should we include definitions in this thread or start a new one for that purpose ? 1

sethoflagos Posted July 23 Posted July 23 20 hours ago, Agent Smith said: The reciprocal chemical reactions of photosynthesis and respiration I alluded to in my OP... For me, the evolution of photosynthesis is quite a serious challenge to GH. At the time, all organisms were anaerobic. Oxygen, merely a waste product of photosynthesis, was poisonous to (almost?) all lifeforms including the photosynthsisers. It is estimated that the Great Oxidation Event aka the 'Oxygen Holocaust' reduced the planets biomass by >80% though admittedly, the fossil record is so sparse at this time, such figures have large error bars. If this outline is accurate, then the development of photosynthesis, while advantageous at least in the short term to the cyanobacteria responsible, can hardly be described as advantageous to the whole planetary ecosystem at that time. If GH is relevant to this epoch, we seem obliged to accept that photosynthesis was evolved for the benefit of the aerobic organisms that followed in the wake of the GOE. This is contrary to all we have learnt about evolution in that it is clearly blind to future consequences. GH seems to put the cart before the horse. Life does not adjust the environment to the benefit of life. Rather life adapts to live in synergy with the changes in the environment to which it is subjected.
