Researcher: Basic Greenhouse Equations "Totally Wrong"

A simplified view of the new equations governing the greenhouse effect
New derivation of equations governing the greenhouse effect reveals "runaway warming" impossible
Mikl?s Z?goni isn't just a physicist and environmental researcher. He is also a global warming activist and Hungary's most outspoken supporter of the Kyoto Protocol. Or was.
That was until he learned the details of a new theory of the greenhouse effect, one that not only gave far more accurate climate predictions here on Earth, but Mars too. The theory was developed by another Hungarian scientist, Ferenc Miskolczi, an atmospheric physicist with 30 years of experience and a former researcher with NASA's Langley Research Center.
After studying it, Z?goni stopped calling global warming a crisis, and has instead focused on presenting the new theory to other climatologists. The data fit extremely well. "I fell in love," he stated at the International Climate Change Conference this week.
"Runaway greenhouse theories contradict energy balance equations," Miskolczi states. Just as the theory of relativity sets an upper limit on velocity, his theory sets an upper limit on the greenhouse effect, a limit which prevents it from warming the Earth more than a certain amount.
How did modern researchers make such a mistake? They relied upon equations derived over 80 years ago, equations which left off one term from the final solution.
Miskolczi's story reads like a book. Looking at a series of differential equations for the greenhouse effect, he noticed the solution -- originally done in 1922 by Arthur Milne, but still used by climate researchers today -- ignored boundary conditions by assuming an "infinitely thick" atmosphere. Similar assumptions are common when solving differential equations; they simplify the calculations and often result in a result that still very closely matches reality. But not always.
So Miskolczi re-derived the solution, this time using the proper boundary conditions for an atmosphere that is not infinite. His result included a new term, which acts as a negative feedback to counter the positive forcing. At low levels, the new term means a small difference ... but as greenhouse gases rise, the negative feedback predominates, forcing values back down.
NASA refused to release the results. Miskolczi believes their motivation is simple. "Money", he tells DailyTech. Research that contradicts the view of an impending crisis jeopardizes funding, not only for his own atmosphere-monitoring project, but all climate-change research. Currently, funding for climate research tops $5 billion per year.
Miskolczi resigned in protest, stating in his resignation letter, "Unfortunately my working relationship with my NASA supervisors eroded to a level that I am not able to tolerate. My idea of the freedom of science cannot coexist with the recent NASA practice of handling new climate change related scientific results."
His theory was eventually published in a peer-reviewed scientific journal in his home country of Hungary.
The conclusions are supported by research published in the Journal of Geophysical Research last year from Steven Schwartz of Brookhaven National Labs, who gave statistical evidence that the Earth's response to carbon dioxide was grossly overstated. It also helps to explain why current global climate models continually predict more warming than actually measured.
The equations also answer thorny problems raised by current theory, which doesn't explain why "runaway" greenhouse warming hasn't happened in the Earth's past. The new theory predicts that greenhouse gas increases should result in small, but very rapid temperature spikes, followed by much longer, slower periods of cooling -- exactly what the paleoclimatic record demonstrates.
However, not everyone is convinced. Dr. Stephen Garner, with the NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), says such negative feedback effects are "not very plausible". Reto Ruedy of NASA's Goddard Institute for Space Studies says greenhouse theory is "200 year old science" and doubts the possibility of dramatic changes to the basic theory.
Miskowlczi has used his theory to model not only Earth, but the Martian atmosphere as well, showing what he claims is an extremely good fit with observational results. For now, the data for Venus is too limited for similar analysis, but Miskolczi hopes it will one day be possible.

doesnt suprise me, i've heard alsorts about this
for me, i dont think we can deny the climate is changing.... and i suspect that while its supposed to change naturally, i thing we've played a relatively small hand in it... making it just that little more severe in places. but there are people out there who wanna cash in on this and they'll tell you without flinching that its all our fault and everything would be rosy if we didnt exist.
basically they've amplified a problem into an all out catastrophe and they've done it by being alarmist and by bending the truth.
theres idiots on both sides.... some claiming nothing is happenening at all, others running around screaming about the end of time..... theres people being dishonest about it, like these guys, but it doesnt mean theyre all like that.
I am seriously worried that our flagship gridded data product is produced by Delaunay triangulation - apparently linear as well. As far as I can see, this renders the station counts totally meaningless. It also means that we cannot say exactly how the gridded data is arrived at from a statistical perspective - since we're using an off-the-shelf product that isn't documented sufficiently to say that. Why this wasn't coded up in Fortran I don't know - time pressures perhaps? Was too much effort expended on homogenisation, that there wasn't enough time to write a gridding procedure? Of course, it's too late for me to fix it too. Meh.
I am very sorry to report that the rest of the databases seem to be in nearly as poor a state as Australia was. There are hundreds if not thousands of pairs of dummy stations, one with no WMO and one with, usually overlapping and with the same station name and very similar coordinates. I know it could be old and new stations, but why such large overlaps if that's the case? Aarrggghhh! There truly is no end in sight... So, we can have a proper result, but only by including a load of garbage!
I read the link BCS supplies and omg those guys are boned. Basically making up data from completely disorganized data sources using programs they have little idea about. In addition to admittig they have zero clue about what's going on and admittig to just glossing over errors and producing data with very slack tolerances.
And this is info that policy is made on and huge sums invested on
These are very promising. The vast majority in both cases are within 0.5 degrees of the published data. However, there are still plenty of values more than a degree out.
Conversion was hampered by the discovery that some stations have a mix of % and % x10 values! So more mods to sp2cldp_m.for. Then conversion, producing cldfromspc.94000312221624.dtb. Copied the .dts file across
as is, not sure what it does unfortunately (or can't remember!).
Examined the program that converts sun % to cloud oktas. It is
complicated! Have inserted a line to multiple the result by 12.5 (the result is in oktas*10 and ranges from 0 to 80, so the new result will range from 0 to 1000).
Well, dtr2cld is not the world's most complicated program. Wheras cloudreg is, and I immediately found a mistake! Scanning forward to 1951 was done with a loop that, for
completely unfathomable reasons, didn't include months! So we read 50 grids instead of 600!!! That may have had something to do with it. I also noticed, as I was correcting THAT, that I reopened the DTR and CLD data files when I should have been opening the bloody station files!! I can only assume that I was being interrupted continually when I was writing this thing. Running with those bits fixed improved matters somewhat, though now there's a problem in that one 5-degree band (10S to 5S) has no stations! This will be due to low station counts in that region, plus removal of duplicate values.
^ And your stance is great!...as long as any Government does not use that premise to restrict freedoms or overly tax on what might now be corrupted science. Put the responsibility into the hands of the people, let them decide on an individual basis; if consumers want electric cars, then the car companies will produce them.
Never turn to a Government to solve problems, as they will always find a way to bungle it, and then claim no responsibility for their errant actions.
Agreed. In general I support those things but that doesn't mean I'll support any and every law because the gov claims it will help the environment.
I do think the government has to get involved to some extent though. When it comes to setting pollution limits, waste and recycling programs they pretty much have to. Unfortunately, it apparently isn't as simple as if consumers want electric cars then companies will produce them. The documentary 'Who Killed the Electric Car' showed pretty clearly that some people were willing to buy GM's EV1 in the 90s. Yet GM decided to literally crush working EV1s instead of selling them to willing buyers.
The bias in the 'Who Killed the Electric Car' film wasn't lost on me. I've heard the reasons for why they refused to sell the car before. I understand that from GM's cost/benefit point of view it just wasn't worth the risk. Still makes me wonder though how so much research and development went into it only to get completely killed despite some willing buyers for cars that already existed.
Yeah I thought about that recently as well. At the end of the work day there will be a gigantic spike in power consumption and I don't see how renewable energy could possibly adjust to that.
