Actually, most of the Mesozoic (Dinosaurs era) was below 2000 ppm and with average closer to 1000 ppm
As hard as you are trying, you do realise spamming BS! wont make you correct.
Actually, The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period- about 7k ppm.
Fact is CO2 levels have been falling for more than 50 million years.

Again it was NOT C02 that is attributed to the many mass extinctions- but rather asteroid impact, volcanic activity/massive eruptions, acid rain, changes in ecosystems etc.

Wow Genava, I really admire your patience and diligence, although you surely must know that people will never admit defeat and remain in their alternative facts bubble.
For a change, I'd like to ask you what do you think of the premise of the thread: do you think it's too late? Do you think we as a species will be able to avert disaster?

First of all, I love to argue and I have a lot of tenacity. They will tire before me. Moreover, it is a good exercise to show how to respond to those common myths and lies. Ignorance and ideology give opportunities to spread correct informations from scientific literature. Stario and B.W. are actually counterproductive and are backstabbing their own side with their trolling.

No it is not too late. Each degree in addition is a different world in the end. It is too late to avoid damages to natural habitats and human societies but the amplitude is still to decide. We have the hand on the thermostat. Tipping points are not necessarily unavoidable on the very long run. Any action to stabilize the situation worth it.
The tipping point worrying me the most is a human and economical one: at some point acting fast enough will be costly enough to damage our societies. Those conservatives are putting the bullet in the gun that will kill the western civilization.

Exactly the way I feel. I've gone through these lists of links he posts too many times and virtually every instance I find that they are all based on, or draw their information from, data that has been manipulated or manufactured. Instead of presenting one, or even two, pieces of "evidence" he gives us lists as if that is conclusive to winning a debate.
Frankly, I don't have time to go through and address all these fraudulent sources, but he keeps putting them up.
It would be nice if he could give just one study that isn't based on bad data or makes its conclusion based on previous studies that were resolved using manipulated data.

I tried multiple times to argue with you on the scientific aspect but most of the time you stay strictly political, probably a good instinct since you have publicly shown your inability to understand basic math while questioning academic researches.

Even the geologists are evil now. It is probably a conspiracy of intelligent people against those suffering of Dunning-Kruger bias.

Hahaha! I bet you printed that out and posted it on the wall! If I were concerned about my credibility I would have deleted the comment. Everyone makes mistakes and I admitted it, but you on the other hand won't. You're the only person on the planet that has never made a maths error; that's something even Einstein can't say. Which begs the question, why don't you admit that Stario was right about previous CO2 levels?
Here's a video of Happer destroying every argument you've put forth in this thread. The video is poor quality, but anyone who has followed this thread will recognize the charts he shows. He starts out by illustrating how Al Gore faked the cover of his book and then devastates the AGW argument:
And BTW, it is a political argument. You don't build a scientific argument on fake and manipulated data...Oh wait, you do.
Here's another in which he comments about the El Nino effect on warming. It was made before the study, which I linked, that showed the Ninos' were caused by Geothermal activity. Your rebuttal was based on a Politifact review (more hilarity).

You have been soundly and obviously defeated. And why would you even build up resistance, this is threatening your country as well. Why are you this resistant? Is it because Geneva is European and no Murican, admits defeat to Euro-trash? This makes you look worse and worse, you know. There is a limit to stubbornness, which is when it turns out to be conceitedness and undeserved arrogance.

Did I say that? No. You are assuming it and you like to portray me like an arrogant person. Making mistakes is part of everyone's life and we are all ignorant on different subjects. So your lack of experience with common math is not demonstrating you are less valuable as a human being. But a big part of wisdom is knowing what you don't know and on which area you lack expertise. Obviously if you are struggling to understand this level of math and an unit's abbreviation commonly used, I will assume you don't have any experience on natural science.
This is really what bothers me with your attitude. Not your mistake directly. But because you are judging harshly the work of scientists while you do not have the ability to evaluate the quality of scientific arguments. You seem to rely on political sources and you evaluate their accuracy thanks to their political spectrum. Rarely you go to the core of the argument and when you do, honestly this is not really helping your reputation.
Like this time, next to the page of your mathematical mistake:

But he simply replied "that image says it is an anomaly" without understanding the point of the map and the principle of the anomaly which is used in any publication about climate change. This is funny to see that he didn't understand this concept while he is arguing about anything you bring on the subject, clearly an indication that he is never making the effort to understand the information. Now you are teaching him the principle of the anomaly and now he is cherry-picking the only thing he saw to argue about, trying to move the talk to another subject once again.
Sorry to lessoning you here but I hope you will understand somehow why your attitude is far from helping you to convince other people. Neither helping the thread to stay peaceful.
I am making mistakes like anybody do and I do have misunderstanding, I am far from knowing everything. In fact sometimes I am not sure how to respond to a contrarian argument about climate stuff.

Big differences to note before to start this kind of comparison:
During the Paleozoic, the Solar output was 4% smaller than today. This is due to the stellar life-cycle of our Sun, it is something also explained in the faint young Sun problem. Which means that the greenhouse effect should compensate this lower output, around 12 W/m2, so it means around 2000 ppm of CO2 to only compensate this. Solar activity is varying slightly century to century and millenia to millenia, but in the case of hundreds of millions of years, the stellar evolution of our Sun should be taken in account. This is where most of the variations is happening.
Moreover in the Late Ordovician when the ice age you are talking about happened, there was a supercontinent known as Gondwana locked in the South Pole. This kind of configuration is known to enhance ice ages through the albedo feedback (polar ice caps are more stables as ice sheets over land than sea ice). And when this ice age occured, the CO2 was dropping quickly in the same time.
Although, the exact trigger of this ice age is debated, the role of CO2 decreases in the amplification of this event is not. Recently, a candidate has been found to initiate the chain reaction of feedback processes, a meteor: https://earthsky.org/space/did-an-as...e-age-on-earth

It only takes a couple of seconds to post those links, but it takes a lot of time to go through it all so I'm only going to comment on the video of Alley.
In the video he claims that the world was dominated by water 4.4 billion years ago. I don't believe this is correct. It is true that there is evidence of water 4.4 billion years ago, but that is a completely different scenario from a world dominated by water. It is just another example of distorting the facts to fit a conclusion.

Exactly as it takes a couple of seconds to write a dull trolling comment and a lot of time to write something with arguments and references. I did several times the exercise to write a proper answer to your babbling and generally you responded with an irrelevant comment beside the point with a link on something else following.

His argument, I think, is based on the fact that there is little indication for extensive plate tectonics earlier than 3 billions years ago. Most rocks found suggest oceanic crust and volcanic islands during the Hadean and early Archean, so an Earth mostly covered by ocean (far above the actual situation). That is not a settled debate but for the moment, the evidences suggest this explanation.

Of course neither of you watched the video of the presentation by Happer I posted in the link.

That is the point. He wasn't talking plate tectonics. He was talking about the Earth's water content 4.4 billion years ago. It is an unsettled issue and he was stating something as fact. That is precisely what you warmists do. Did you bother watching the video I posted where he listed the beneficial effects of rising CO2 levels. No you didn't. A fun fact: the limit of CO2 on spacecraft is 7000 ppm.
I don't have to watch any more vids about the tpopic.

That's just laughable. I would have said 'ridiculous' but apparently that word is now considered an insult. You say I have been soundly defeated, but you refuse to look at anything I've posted that is contrary to your views. Happer is one of the world's most distinguished scientists and in the video he soundly destroys the arguments put forward here by you and others.
As far as I'm concerned I win. I have been patient and reviewed nearly all of the copy and paste links posted. As I said they are all based on or rely on fraudulent or manipulated data. You guys, on the other hand refuse to even look at anything that is contrary to your worldview; cult-like.
That is the point. He wasn't talking plate tectonics. He was talking about the Earth's water content 4.4 billion years ago. It is an unsettled issue and he was stating something as fact.
I don't understand you. Are you talking about what Alley is starting to explain at 09:16 in the video? He is simply saying that the geological evidences are showing that water was mostly liquid 4.4 Gyr ago. I thought you were reacting about the idea of a water dominated world 4.4 Gyr ago, that's why I talked about the plate tectonics. But if you are reacting on the idea of liquid water then it is a different matter. If this is the case, I suggest you to read a bit more on the Hadean eon and to calm down your untimely accusations. If you could clarify exactly what is bothering you and giving us your opinion, it would be helpful. For the moment your two replies on the video are unclear to me because the point of Alley is specifically on the evidences of liquid water during this eon.

The point is: in our time scale, the effect is more detrimental than beneficial for the natural vegetation. There are other nutrients that will limit the fertilization and the huge impact of CO2 on the water cycle from changes in temperature is clearly the point to consider the most.
Ecosystems won't be able to cope with these changes in precipitations and temperatures, there will be a biodiversity loss and this is piling up with dozen of other impacts from human societies on the natural world.
Even the idea that CO2 is good for the plants is a very gross picture missing the diversity of the vegetation. The different biological genus of plants do not react the same way for an increase in CO2. Some plants are better to take profit in the increase than the others. Which it means that plants having the most gain with increasing CO2 will competitively exclude the others. So it will have huge consequence on plant biodiversity and ecosystems. Biological evolution is slow and new adaptations won't solve the problem.

I'm sorry, but I couldn't bring myself to watch that man's presentation in its entirety a second time. His screeching voice was unbearable. However, I did suffer through the first 16 minutes, which should be sufficient to address your point. He was saying that the world was "dominated" by water at 4.4 billion years ago. I believe he is implying that the world's water content was is what it is now. A lot of scientists believe that estimate is off by .4 billion years or so, but he stated it as fact when he knows that the issue isn't satisfactorily resolved.
Going farther, he assumes that the ice ages were caused by variations in CO2 levels, then shows a chart that supports he premise. Unfortunately, that chart shows CO2 level variations that range from over 7000 ppm to several hundred ppm. For any thinking person, the chart has no relation to his argument at all, but yet he uses it. It is just crazy. I think he uses it to underpin his claim that the ice ages were caused by variations in CO2 levels, but I can't say for sure because the relative comparison is so bizarre.

When you start out with a false assertion and manipulated data, such as Al Gore's book cover as well as its contents, you can't blame people for suspecting deception.

Biological evolution is slow and new adaptations won't solve the problem.
Finally, it doesn't adress the issue of ocean acidification, which also an important risk for ocean ecosystems.
At this point I wouldn't trust anything the IPCC publishes. Here's the truth of the situation, it is obvious that there were ongoing studies about the fact that some plants benefit more from higher levels of CO2 and some do worse. That is not the issue and that is not what "climate alarmists' were claiming originally. The original claims were all about causing alarm and indoctrinating school children and simpletons into thinking that only catastrophic effects will come from increased CO2 levels, etc.

I am not asking you to watch it a second time. Your memory seems to have slightly changed his discourse, his whole point is actually is based on the fact there is liquid water 4.4 Gyr ago. Something you are not contesting in regards of your first message on the video. So I find your attitude inappropriate against him.
Going farther, he assumes that the ice ages were caused by variations in CO2 levels, then shows a chart that supports he premise. Unfortunately, that chart shows CO2 level variations that range from over 7000 ppm to several hundred ppm.

I think he uses it to underpin his claim that the ice ages were caused by variations in CO2 levels, but I can't say for sure because the relative comparison is so bizarre.
Do not confuse quaternary ice ages with the older periods. The older ice age happened on a context of weaker solar radiation (I already explained my point about this aspect of stellar evolution, you didn't reply so I assume you are agreeing on this matter). In these situations, older of hundreds of millions of years, the ppm of CO2 can be above 1000 and still not be able to compensate the whole solar radiation fainter than in our recent era.
When you start out with a false assertion and manipulated data, such as Al Gore's book cover as well as its contents, you can't blame people for suspecting deception.
Again the same rejection based on no scientific argument. They are evil, they talk about climate change so climate change is hoax. You have no care about my arguments that the consensus on climate change was already displayed in the 1960s, far before any politicization. Neither that most of the denier stuff you posted here used lies and manipulation to build their discourse, totally hypocritical to be blind on this matter.
At this point I wouldn't trust anything the IPCC publishes. Here's the truth of the situation, it is obvious that there were ongoing studies about the fact that some plants benefit more from higher levels of CO2 and some do worse. That is not the issue and that is not what "climate alarmists' were claiming originally. The original claims were all about causing alarm and indoctrinating school children and simpletons into thinking that only catastrophic effects will come from increased CO2 levels, etc.
Absolutely shameful!
Yeah, IPCC is evil so you are not paying attention to my arguments. Didn't even care to reply as always. You continue your political babbling and try to move the topic on more political arguments totally irrelevant to the current talk.
