And still waiting for you to explain the past warming periods........104 pages and STILL waiting for someone to come up with a mechanism that explains the current warming trend.

Hello; If you have been on this thread from the start you will have seen a similar pattern. He and one other made a big deal out of the way I use the term "theory". Not that my comments could not be followed but several posts about it and leveling personal attacks along the way.I apologize. I just googled "oldest continuous ice cores". I should know better.
The oldest continuous ice core records extend to 130,000 years in Greenland, and 800,000 years in Antarctica. Ice cores are typically drilled by means of either a mechanical or thermal drill. Both types of drills incise an annulus, or circle, around a central, vertical core.
Interesting though out of all the things I have said that is what you comment on.
Hello; By my count this must be four or more posts since you officially quit the thread?Another factual error. There was NEVER a scientific consensus that ALL the glaciers would be gone by now.
Stop reading shit.
The simple answer to your question, is this:Ice Core Data Help Solve a Global Warming Mystery - Scientific American
Hello; Some interesting things in this article. One is studies of ice cores have suggested that temperatures had gotten warmer some 1400 before the CO2 levels rose. Yes it got warmer before the CO2 level rose. This article claims to have narrowed this difference down to 200 years. That the temperatures warmed "only" 200 years before CO2 levels are measured to have risen. The reason given has something to do with how gas bubbles "move' around in the ice.
So I am not an ice core specialist so this becomes a guess. I was given to believe the value of the ice cores was that the ancient air is trapped and by measuring things such as lengths some sort of timeline can be had. Tree rings I can read and have done so. It is pretty clear from one season to the next. I have watched videos of ice cores over the decades but must have missed the fact the air can move around. I do get while before the snow fall becomes compressed that the air is not trapped. I can even see how when the ice begins to be more solid ice there can be some movement. I have been going on faith that the ice scientist had it figured out a good while back.
Well this gets back to one of my so far ignored questions. That of significant numbers. I will be brief. Today we can measure fractions of a degree on a daily basis. I have asked what the time interval might be from the ice cores. It would appear the author of this article is proud to claim he may have narrowed a range from 1400 years down to 200 years. I concede this does not answer my question directly, but it is among the first few articles I have searched so far.
My earlier question was could there be an period in the past of similar warming as today which could be hidden because the ice core record because the data intervals are too wide? I still do not know if the data from the ice has significant gaps.
I have collected raw data and collated it onto graphs. After you get enough data points you can sort of summarize the line of the graph to get the curve. It is important to know the scale of the time line. I would be comfortable with a scale of say ten years. Not so comfortable with a scale of a century. No confidence at all with a scale of over 100 years. I could not make confident predictions on a time line of the next 50 or 100 years from a data point scale of less than a year or so.
Before I go let me ask this. Even if the author is correct and has narrowed the time down to 200 years. It still reads that the warming happened 200 years before the CO2 levels rose, does it not? That ought to be a backward thing from what we are being told about CO2 currently.
Itās my thread. I can and will do as I please.Hello; By my count this must be four or more posts since you officially quit the thread?
quote burkey "Thereās plenty there that I take issue with but Iām not taking part in the discussion except to correct statements that ar factually incorrect."
So you are still officially quit but have reserved the option to be a fact checker? You did start the thread but it has a life of it's own now and after all you did "officially" quit. I like writing that you officially have quit while responding to one of your posts.
Is that like, "it's my ball and I'm going home?"Itās my thread. I can and will do as I please.
I suggest looking in the mirror.Iāve decided it best to continue to try and educate those who think their ignorance of the topic is a legitimate threat to the scientific consensus.
Hello; I know nothing about them. I see the videos on TV from fighter planes, but cannot make anything out of it. None of it makes sense to me. I will have to defer to the experience of the pilots.What we should be talking about is UFOs though.
Iām not suggesting that you werenāt taught these things. I suggesting that the things you were taught werenāt supported by the scientific consensus.My middle school actually did a fund raiser for Greenpeace because the polar bears were going extinct. Don't hear much about that either anymore.
And yes we learned the glaciers would be gone in our lifetimes.
No, that was NOT the consensus. What youāre talking about is the hyped up media reports that came from journalists who needed a sensational story.I don't have any of that. I am just telling you what the consensus was in middle school. The fear that was taught is that is glaciers would be gone soon if we didn't change the planet.
That was the start of all the green house phase.
This is where the "scientists" become disconnected from science. Average temps are on an increase - from what?Hello; Not gonna be able to give you a clear answer. First the average temps around the world do measure out to be on an increase.
You very clearly said that none of the predictions had come true - whereas clearly this is happening. I didn't see you specify what sort of glaciers. Just because they have not 'all gone' doesn't mean they are not reducing as predicted, and this was just one example.Are all the glaciers gone? Do we even hear about that anymore?
BTW read you stories before posting. That was about mountain glaciers AND
Scientists have described more than one hundred thousand glaciers in the World Glacier Inventory, but only a small fraction of these have been consistently monitored for long enough to measure climate-related changes in their size or mass. Scientists refer to this collection of about 40 glaciers as "reference" glaciers.
The reference is .016%. Nice.
As has been pointed out many times over long term factors are very slow to change but anthropomorphic changes are having a rapid impact.This is where the "scientists" become disconnected from science. Average temps are on an increase - from what?
The fact is, average temperatures are on the decrease. The Earth is in a cooling off period. Just like the stock market, nothing goes straight up and nothing goes straight down. Along the way down, there will be highs and lows. We may be on the upswing of a cycle, but ultimately, we are cooling off. The Earth goes through many cycles, most notably, the 100,000 year cycle. It will continue to do so, with or without humans. We are just along for the ride.
