VOLCANO MADNESS: Re: [Geology2] Re: your opinions

Hi..this is Allison. I realize your question was not aimed at me but I would caution you to be real skeptical about any piece of wood touted as "the true cross". Your wood may be indeed be 2000 years old but the Romans used a permanent stake in the ground with the crosspiece carried by prisoners and that was what was hoisted up. So the stake Jesus was crucified on was likely reused again and again and finally it likely ended up in a woodpile somewhere. Wood was scarce and the Romans had to really look to get wood long enough and strong enough to support a man. I can cite you couple of links to this information if you like. We can go offline. I am a practicing Catholic but in view of the huge business in relics in the Middle Ages and the lack of provenance for the most part of the various bones and pieces of cloth and whatnot, it is highly doubtful that many relics are what they are supposed to be. In May I am making a pilgrimage on the old Santiago de Compostela that was so popular in the Middle Ages,despite the fact that I really doubt St. James is buried in the Cathedral. But hey..sometimes there is some truth in a tradition. Allison

The cooling trend of late is buried in the midst of a longer-term warming trend and not only that but even during that relatively short-lived period there has continued to be changes aplenty observed in the natural world that indicate the climate continues to change overall in a warmer direction.

Evening Fossrme.

I am travelling at the moment and hate doing long replies on my phone so apologies for being brief.

The cooling trend over the last decade is pretty well established now and is accepted by both sides of the argument. The discussion has now moved on to causes and implications as it is certainly not the case that it 'proves' anything one way or another.

On the subject of tree ring dating I suspect that a sliver of the cross would be too small to get an accurate date. You would need probably at least a decade or so represented in the rings to start yo get a pattern. Several years ago I was involved in a dating project in the UK dating medieval buildings and as a rule it was only main beams which were large enough to get dates.

Thanks for all the info. No, I had not heard about all the problems with IPCC etc. That got me to do a search on the subject and there seem to be plenty of people complaining, and the issues they are talking about are important ones. It's hard to tell, though, because if you search for problems on any subject it will always come back with many of them.

I'm sure that there have been times in the past when CO2 levels were higher and the atmospheric temperatures were lower than today - that is to be expected because irradiance from the sun and other factors influence those temperatures, but over the short span we are looking at they have been relatively constant while temperatures were rising along with CO2 concentrations.

Re the Ethiopian rift vent. I think it is going to take a lot more than that to get anyone seriously worried.

If you have time for a few more questions:

1) You said that we have come to the possibility of global "cooling"? Can you tell us who says that and why? Someone (maybe Plimer) claims there is a cooling trend, which he can justify only by picking the highest starting temperature point he can find in the last decade.

2) I've been talking with a historian of early Christianity whose specialty is dating events around the time of Jesus. There was an article in the papers a few weeks ago about a relic from an early Christian church that was supposedly a piece of the crucifixion cross. Just a chunk of wood with a cross carved in it. What are the chances that it could be dated from the tree rings, and can you give a guess as to what kind of accuracy might be expected?

Thanks for the comments

I don't know if you are aware of the scandals throughout the scientific community as a whole regarding: falsified data, peer review which did no fact checking but simply read the abstract, excluding alternate POV reviewers in order expedite getting published. Without going into detail, I was trying to express that the debate is full of scandal and cheating so research can't be taken at face value-nor can the thousands of bloggs out there pro or con-- nor the media reports which attribute every unusual weather event as "global warming"--WRONG it is weather --not climate. I just saw an article by a "science writer" that said that 2012 broke several "climate" records when what she meant was "weather" records. This is lost on most of the public

Nothing about this rift is different at the surface from the Triassic rift(190-200mybp) which extruded 1000± feet of basalt up an down the Hudson River Valley outside NYC( 300ft remain today above surface). We really don't know just how much basalt was extruded because most of it eroded into the gap between the North Americana nd Africa plates. It is my opinion that the major extrusive event has more likely than not already started. This riftting started before humans walked the planet!

If we can't make off the cuff WAGs during conversation what a bore it would be. But if I were writing an article making as controversial and argumentative a statement as Plimer did I would realize, as any reputable scientist does, that it should depend on facts that are presented at the time.
> >R: Agreed

> >Not that I would place any confidence in anyone'sÂ climate model, as so far there have been what 78(?) attempted Climate Prediction models and NONE of them has proved accurate when past climatological data was run back through them to check for validation. Some one pointed out that climate is not uniform and extreme highs and extreme lows of whatever is being measured make the scene look "average". Â Super computers coming on line each day will help isolate regional climates forcing on adjacent and ultimately world climate. Â Part of that will be identifying the true heat budget of the globe and how it moves about the environment.C:Good info. I'm wondering what you mean when you say none of the climate models has proved accurate. Accuracy is a matter of degree.
> >
> >R: Ha Ha Punny...degrees--get it? Accuracy is more than "degrees" but well defined statistical measures on whether to accept or reject a model. What I mean is that no model so far has captured reality with enough "fit" to be endorsed as suitable for forecasting the future. Keep in mind that a 5% generic error this decade can become a 10% error -- just arithmetically but curves usually follow algebraically. No model captures the majority of the 60-70 plus known climate forcing cycles ( solar output, precession, wind and current migration etc.) And more are being discovered monthly. I am skeptical that any chart you've seen on model suitability isn't skullduggery. If you know the history of the first IPCC model used to predict Al Gore's figures was tweaked until it got the numbers the IPCC staffers wanted. The whole model was fiction used to back up a predetermined outcome. That is NOT a valid predictive model.

It is the CO2 that is going up and as it increases it forces increases in these other gases which are multiplyers of the CO2 increases. If we stabilize the CO2 we stabilize the temperature.

Somewhere in the bowels of academia is a study which showed CO2 levels to be several times today's levels yet the global temperature was lower than today. Again without understanding all the forcers and how they feedback, focus on CO2 alone is misplaced effort and If I may say so--wasted karma.

Â I do know from my climate studies that CO2 in the environment doesn't behave simplistically like it does in the lab owing to unaccounted for feed backs/forcers. Â I've said before that we are only now getting the computing power to model the atmosphere GHGs--Of which water vapor and methane are far larger players than CO2.

Â While plants are "greener" and temperate regions are greening more (pro) ocean acidification is endangering coral reef communities( some of us think)( con). Â I think the biggest threat finding solutions is the "tunnel vision focus"- on CO2 for it stifles finding out how it really behaves in the environment--not simply the atmosphere -or lab or in the computer etc. Â Take a simple survey with all the pro or con AGW proponents by asking them just what is the mechanism of the "green house effect" and 99% of them will give you a wrong answer. Â ( Hint 99% of CO2's heat conversion contribution is within 3 -4 meters of the ground). Â Oceanic CO2 is an almost entirely different player but owing to the exchange of gas to and from the hydrosphere it has to be factored in.
> Â This is one of the reasons one cannot make a one on one calculation of a heat gradient attributable to atmospheric CO2.>C: Why does the fact that heat conversion is within 3-4 meters of the gound mean it is not a problem? That process happens continually during the day and the hot air rises so there is a continual circulation of that heat through the atmosphere.

This has come to fruition as fraud and game play has been discovered, Much of the justification used in the original IPCC report has been found faked, fudged or outright wrong. We have in just ten years gone from Global Warming to Oops Climate Change now to Ahhh Global Cooling-- We might see and Ice Age return in 30 years.

That is my perspective and I am off the soap box now on why it makes sense to put science back in the lead and let them find out what is really going on.
