I looked at the statements you quoted, but I don't understand what exactly in them you don't agree with.But they all harp on the CO2 increase is caused by the Industrial Age.
You're a critical thinker. I'm a lateral thinker. I am approaching this problem differently so it might take a second to see where I am at.I looked at the statements you quoted, but I don't understand what exactly in them you don't agree with.
The source of the CO2 in the atmosphere is tracked via the proportion of Carbon (C) isotopes. Fossil fuels have more decayed Carbon because they were buried underground, and that carries over to the CO2 produced by burning them.
In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols (e.g., "pollution") could have cooling effects as well.
"A fire-breathing dragon lives in my garage"
Suppose (I'm following a group therapy approach by the psychologist Richard Franklin[4]) I seriously make such an assertion to you. Surely you'd want to check it out, see for yourself. There have been innumerable stories of dragons over the centuries, but no real evidence. What an opportunity!
"Show me," you say. I lead you to my garage. You look inside and see a ladder, empty paint cans, an old tricycle--but no dragon.
"Where's the dragon?" you ask.
"Oh, she's right here," I reply, waving vaguely. "I neglected to mention that she's an invisible dragon."
You propose spreading flour on the floor of the garage to capture the dragon's footprints.
"Good idea," I say, "but this dragon floats in the air."
Then you'll use an infrared sensor to detect the invisible fire.
"Good idea, but the invisible fire is also heatless."
You'll spray-paint the dragon and make her visible.
"Good idea, but she's an incorporeal dragon and the paint won't stick."
And so on. I counter every physical test you propose with a special explanation of why it won't work.
Now, what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there's no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same thing as proving it true. Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder. What I'm asking you to do comes down to believing, in the absence of evidence, on my say-so.
i'm not following you. how can they show a corresponding time period if there are no corresponding time periods? aren't YOU supposed to show a corresponding time period that would prove their assertion wrong?Asking them to show a corresponding time period.
No to make a accurate claim you have to show a corresponding a time period to support your claim in order to show that it is valid.i'm not following you. how can they show a corresponding time period if there are no corresponding time periods? aren't YOU supposed to show a corresponding time period that would prove their assertion wrong?
but their alleged claim is that it is unprecedented. you gave us the definition of unprecedented "never known before".No to make a accurate claim you have to show a corresponding a time period to support your claim in order to show that it is valid.

How can they show something that doesnt exist?
as i said..i'm not following your logic at all. (and i do smell like the color nine)
no. you post super long comments and i have a low attention span.Did you read the "there's a dragon in my garage argument" I posted.
I don't see how you can't follow. Their alleged claim and they are making the claim is that the change is unprecedented.
Therefore the burden of proof is on them to substantiate such a sensational claim.
And they can't as you yourself have stated.
Unsubstantiated claims shouldn't be taken seriously.
It's not up to me to prove a baseless theory. It's up to them to support their theory. On which their entire argument hinges on.no. you post super long comments and i have a low attention span.
or... you could just prove their claim wrong by showing by showing a 200 year period that disproves them.
that's silly.They could just show me a 200 year period that proves I am wrong.
Why you want me to show a 200 year period. To prove it isn't?that's silly.
driving force? i have no idea but considering the huge population jump since before the industrial revolution, it is logical to assume all the crap we pump into the air has some effect.Do you believe that mans CO2 emissions during the industrial age are a driving force in climate change.
You still haven't shown me a source that claims that.Taking say a 200 year snapshot of history from the last 450,000 years + of warming and cooling cycles then claiming it is proof of a never before seen spike in CO2 and temperature.

Rambles shows up in in-site searches. but the in-site search is finicky.I know I've discussed this kind of evidence before, this year even, but I am having trouble finding it: did it end up in Rambles?
You still haven't shown me a source that claims that.
What you have shown me are claims that this spike is man-made.
So what we have here is a garage filled with provably man-made CO2 from burning fossil fuels that is also heating up. You're telling me it must be caused by something else, but can't show me what it is. Who has the invisible dragon, you or I?

Contemporary climate change includes both global warming caused by humans and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are more rapid than any known events in Earth's history.[2] The main cause is the emission of greenhouse gases, mostly carbon dioxide(CO
2) and methane. Burning fossil fuels for energy use creates most of these emissions. Agriculture, steel making, cement production, and forest loss are additional sources.[3] Temperature rise is also affected by climate feedbacks such as the loss of sunlight-reflecting snow cover, and the release of carbon dioxide from drought-stricken forests. Collectively, these amplify global warming.[4]
What you have shown me are claims that this spike is man-made.
The film's thesis is that global warming is real, potentially catastrophic, and human-caused. Gore presents specific data to support this thesis, including:
the scientists do. your wiki quote sources do. Members here on MB do if the topic comes up.But they don't supply definitive support
Really?the scientists do. your wiki quote sources do. Members here on MB do if the topic comes up.
You are basically arguing for your backwards logic based on some people you chat with on Facebook? who are "they
The fallacy of shifting the burden of proof occurs when someone making a claim does not respect their obligation to provide the needed evidence for it, but instead attempts to shift the burden to their opponent.
it is a claim unsupported by evidence.
No I'm completely aware of the estimates of CO2 levels in ice cores.Any claim of a precedent is indeed unsupported by evidence. RIght now we have plenty of evidence of no precedent spanning the entirety of human history.
You seem to be unaware that ice cores can be read (which includes CO2 levels) to incredibly high precision - in a good core, even individual seasons can be detected - all the way back from when we weren't properly human yet. Prior earth history I consider irrelevant, we're not looking at Gaia's life support system, we're looking at humans'. So the earth we need to consider is the one we live on, not the one with no plants on land, or when trilobites ruled the waves, or when cold-blooded animals a hundred times our size were cock-of-the-roost.
Now using ice core data show me that exact 200 year time span on any of these earlier three cycles.

Well it's official. Although everywhere else I posted it people understood. No one here is able to understand my point.No. Because that's not the "ice core data". That's a simplified graphic created from the ice core data in order to get a particular point accross.
Would you claim to know everything about a sports car from one photo? Why do you do the same with utterly enormous datasets? And they are enormous - storing the data in its rawest form takes up many many huge refrigerated warehouses around the world.
Then you should be able to point out a correlation when the temperature rose drastically during a 200 year time span in each of the last warming cycles. To support your position.
You didn't quote this before. The claim is, "but the current changes are more rapid than any known events in Earth's history", do you disagree?You must have missed this.
I don't understand why you demand this?But they don't supply definitive support for that theory by comparing similar time spans over previous warming trends while making that sensationalized claim.
good catch. i was wondering why there was a thousand year gap of white on his chart.On the vertical axis the graph stops at 310ppm CO2, but today's CO2 concentration is 419ppm: it's even out of the graph.
The data come from an ice core, I guess they have to discard the first few superficial meters of the drilling due to contamination issues or maybe the ice not being yet compacted enough or some other technical reason. One thousand year should be about the first 10 meters (Vostok Ice Core was 3623m deep).good catch. i was wondering why there was a thousand year gap of white on his chart.
Here is a starting point for an answer to your question. Here is another. It is unreasonable to expect a brief answer that does justice to the mass of evidence, which is why Metabunk has never tried to do so.You can't seriously be debating that statement. Are you pulling my leg or not? If you've ever talked with a "manmade"global warming fanatic they emphasize that man is the cause and has been the driving force since the industrial revolution.
Everybody knows this. But apparently is brand new information around here?

Not to mention everyone is completely avoiding my position and nitpicking around the edges. From sources say 150 years others say 200 years. But they all harp on the CO2 increase is caused by the Industrial Age.

Edit;
I guess I better clarify what's the IPPC is for those who have never heard of it and don't know their standing theory on climate change.
It's The Intergovernmental Panel on Climate Change which is one of the go to sources for the manmade global warming theorists.
Unprecedented" is a negative claim, and not being in the field of pure mathematical logic it cannot be proved except through exhaustive search,
Aren't 450kyears enough to prove the point? It's about twice the time Homo sapiens has been living on planet Earth.I've been re-reading these replies.
That is my entire point.
Your point would be more persuasive if you had actually quoted a claim that refers to unknown events.I've been re-reading these replies.
That is my entire point.
Such a sensational finding, if known anywhere, would certainly soon be widely known among climatologists; the search wouldn't need to be exhaustive if you're looking for a known precedent (that was the claim you did quote).
But I believe climatology doesn't even know any mechanism that could hypothetically cause this naturally.
You're gonna tell me with a straight face that you've never heard the claim that there is a climate emergency because the earth is heating faster than previously due to the industrial revolution?Your point would be more persuasive if you had actually quoted a claim that refers to unknown events.
If your argument is that respected, prominent climate scientists are wrong toYou're gonna tell me with a straight face that you've never heard the claim that there is a climate emergency because the earth is heating faster than previously due to the industrial revolution?
Silly demands like that make me feel like you're just messing with me.
Are you ?
No once again you're putting a false burden of proof on me. I never said they were wrong. My position is they can't prove it by comparing this hundred years to every 100 year period of the last 800,000 years.If your argument is that respected, prominent climate scientists are wrong to
be calling the the current warming "unprecedented" is it really mean of people
to ask you to cite one or two of these instances?
Earth has experienced climate change in the past without help from humanity. But the current climatic warming is occurring much more rapidly than past warming events.
That's great but I've never asked anyone to prove the CO2 levels are higher during this 200 year period.@Fallingdown : the graph you posted is misleading.
The rise in temperatures due to global warming happened in the last 200 years (just google 'climate hockey-stick' graph). In the graph you posted each pixel corresponds to 555 years (about 90 pixels every 50kyears): this means the whole spike of global warming should not even be half a pixel wide in your graph, no wonder it does not show at all. On the vertical axis the graph stops at 310ppm CO2, but today's CO2 concentration is 419ppm: it's even out of the graph. This is a corrected and less misleading version of your graph:
View attachment 47607
It now looks pretty much an unprecedented CO2 spike, doesn't it? And notice the line I drew is two pixels wide for clarity, but it should be less than half a pixel wide to scale correctly also on the X-axis, even spikier than it looks. I'd rather not wait for the temperature delta to show up the same before starting to do something...
(so that your argument doesn't look merely like a lazy straw man?)
So...a long-winded "Yes...nothing more than a lazy straw man..."No once again you're putting a false burden of proof on me. I never said they were wrong. My position is they can't prove it by comparing this hundred years to every 100 year period of the last 800,000 years.
And I've linked statements that were made about (my choice of words) unprecedented.
Here's another will NASA do ?
If things keep going as they have been on this thread. He will dismiss that on a technicality and then ask me to prove it again.

The fact that you refer to the overwhelming proportion of climate scientists,
