It would be very nice to give some sources for your assertions.teo123 wrote: ↑Thu May 28, 2020 1:43 pm I mean, the only way we can claim that is to assume that there is a large positive feedback loop between the level of water in the atmosphere and the level of CO2 in the atmosphere that magnifies the effects of CO2 by around three times.
But the only evidence we have of that are the climate computer models, which we know are inaccurate. The vast majority of climate models predict the amount of infrared radiation emitted from the Earth will decrease over time, when satellite measurements show it has increased. If they are wrong about the role of CO2 in determining the infrared radiation from the Earth, why assume they are right about the role of CO2 in determining the temperature of the Earth?
Furthermore, the warming is basically indiscernible when you look at the temperature records, it gets lost in the noise. See this diagram, for example.
How can anybody think warming that's indiscernible when you look at the diagrams (without using statistical methods, if it would be discernable even then without satellite and far-away-sea temperature data) is going to have serious impact on the ecology?
To me it seems the only thing discussing global warming does is fueling bad policies and making people forget the real problems that are facing ecology, such as super-bacteria.
Well, I am much more educated now, I have published papers in peer reviewed journals about two sciences. Therefore, my intuition (if that's what you like to call it) is better than that of the vast majority of people.Red wrote:to not trust your intuition
Why does that matter? It should be easy to evaluate by somebody who has studied climate science. The truth of a statement is irrelevant to a person making that statement.Red wrote:Where are you getting this information from?
And I am not. There doesn't appear to be a scientific consensus that the global warming is mostly caused by humans.Red wrote:And why are you trusting it over the scientists?
Well, those assertions should be easy to evaluate for somebody who is an expert in climate science.PhilRisk wrote:It would be very nice to give some sources for your assertions.
As far as I understand that, no. The warming because of the Sun getting brighter is not predicted to lead to a feedback loop.PhilRisk wrote:The feedback loop with water vapor is present not only for CO2, but for any warming forcing.
As far as I understand it, we know next to nothing about the history of the temperature of the Earth before the late 19th century. We need to rely on extremely unreliable indicators that show contradictory results. Was there a medieval warming period? If so, how hot it was? Was it as hot as today? Was it even hotter than today? Was there really a Roman warm period? If so, how hot it was back then? Was it as hot as today? Was it hotter than today? And it just gets worse the further you go into the past.PhilRisk wrote: It is a well established feedback loop used as well to explain the paleo-history of earth climate
But this hasn't been observed. In fact, the infrared radiation from the Earth is increasing.PhilRisk wrote:In the short time it will decrease, that is what all models agree upon
But, as far as I understand it, there is no scientific consensus the greenhouse gasses we emit are what's mostly responsible for global warming. Scientists agree it's at least partly responsible, and that's all.PhilRisk wrote:If you see are seemingly simply point refuting established science
@PhilRisk, warming is indiscernible even when you look at the raw data of the long-term temperature records. In fact, there appears to be a cooling trend.PhilRisk wrote:That is not how to identify climate trends.
Just because you're more educated about a subject doesn't mean you have authority to make such claims. I've taken history classes in high school, does that make me qualified to draw my own conclusions about certain historical events? I've also taken physics classes in college, does that give me liberty to make claims about physics? No.
We've already talked about this.
Doesn't mean it's right.
It matters because you're not an expert on this and you have to defer to those who know more than you. Climate science is far more intricate than you're making it out to be.
No, it isn't. This is reminding me of your flat earth arguments, when you talked about how simple it seems to you based on very limited knowledge, when in reality the matter is far more complicated than you're making it out to be since you're ignorant about how much you are unaware of. You're falling for the Dunning Kruger effect yet again.Yes there is. I've told you before.
Wikipedia wrote:There is currently a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities.
Which claims? The fact that the vast majority of climate models predict infrared radiation from the Earth will decrease, while it's actually been increasing? Isn't that easy to evaluate by somebody who knows climate science?Red wrote:Just because you're more educated about a subject doesn't mean you have authority to make such claims.
Well, better that than being a politician or even a Wikipedia editor.Red wrote:Knowing more than the average person about a subject is a very, very low standard.
Then maybe we should stop pretending it's simple physics and settled enough to base policies on.Red wrote:Climate science is far more intricate than you're making it out to be.
Well, as far as I can tell, much of it is. The vast majority of linguistics is like that. And quite a lot of computer science is like that.Red wrote:The scientific process isn't taking some facts and jumbling them around in your head and making conclusions based off that.
And the evidence is a Wikipedia article? Wikipedia doesn't have a good track record of representing the opinions of the experts.Red wrote:Yes there is
It's better if you've had your education in it from professionals instead of learning a few facts and drawing blatantly false conclusions. Again, Dunning-Kruger effect.
That first one is usually a lower standard, and I highly doubt you know more than Wikipedia editors on the subject.
You're projecting, that's what you're doing.
I don't agree with what most politicians want to do about it either, and I do think many politicians are at least mislead about it.
Yes, we do.
That explains why linguistics isn't really a science, but for real science, that doesn't apply. And computer science is more of an engineering discipline than a science (I highly doubt many Computer Scientists even know what the scientific method is).
Since when? Wikipedia has a great track record when it comes to science. How convenient that you won't accept the Wikipedia article when it doesn't fit what you want to believe when you have had no issue citing it many times before.They don't have to be, these larger animals are intelligent and can adapt within their lifetimes quite a bit. How much do you think these zones are moving?
It doesn't have to be, but these animals also carry these plants with them as their habitats move, whether in feces or on fur.
I don't think they have to. You should be able to move a while tailed deer from North America to China or Australia or Argentina. Very few animals are highly dependent on one single food source like bamboo.
I think you're overestimating those dependencies, particularly for the large long-lived animals we're talking about. Smaller species can go extinct without significant harm to individuals.
Mostly insects and flowering plants that depend on them for pollination I would imagine, and even those cases are likely overstated. What kind of animal suffering does that really involve?
I granted that already, but I'm not sure how significant that's going to be.
Have you watched John Stossel or PragerU interview some climate scientists, to hear what the professionals (who consider their views to be rather mainstream) actually say? Most of them say global warming is probably anthropogenic, but that we don't know for sure, and that it's very unlikely anything we do can reverse it. Patrick Michaels appears to be rather reasonable and well-educated about the topic.Red wrote:It's better if you've had your education in it from professionals
And it's also not fine to support policies which supposedly address issues which you don't understand. Be it against global warming or pro net neutrality (every bit is not created equally on the Internet, that's just nonsense, most of the bits on the Internet are created by malware or useless crawlers, and ISPs should have every right to slow down traffic that's probably not useful) or any other hard-to-understand topic.Red wrote:It's fine to not know. It's not fine to assert that you do when you clearly don't.
My friend, there are countless stories of academics being rejected from editing Wikipedia. Vaughan Bell is probably the most famous one.Red wrote:Wikipedia, especially when it comes to topics that matter like science and history, are constantly edited by experts
But if it is, as you admit it, a very complicated empirical question, how can we possibly know for sure?Red wrote:Yes, we do.
Look, I am stunned that you don't see the absurdity in saying stuff like that. I've studied two widely respected sciences to a degree that I can publish peer-reviewed papers about them, and, when I say I disagree with what you are saying how science works, then you claim those sciences I've studied somehow aren't real sciences. What makes you think climate science operates differently than linguistics and computer science? Have you published peer reviewed papers about climate science? You probably haven't published peer-reviewed papers about any science at all, and you somehow have arrogance to suppose you know how different sciences work. It would be different if you were stating some obvious facts, like that astronomy and climate science don't rely on experiments, but you are making claims that only somebody with lots of experience publishing papers in those sciences could make.Red wrote:That explains why linguistics isn't really a science, but for real science, that doesn't apply. And computer science is more of an engineering discipline than a science (I highly doubt many Computer Scientists even know what the scientific method is).
In my experience, the information found on Wikipedia is rarely useful when it comes to linguistics, and it's hardly ever useful for computer science. But since you've never published a scientific paper, you probably don't see why. The information that can be found on Wikipedia is rarely the type of information you need. And when it is what you need, it's not presented in a way to be useful.Red wrote:Wikipedia has a great track record when it comes to science.

Ah yes, how can I forget PragerU and Stossel, both well known for their politically unbiased and objective media. Do you really not consider the possibility that these people distort the truth to fit their agenda?You're just as bad as these politicians then.teo123 wrote: ↑Sat May 30, 2020 10:12 am And it's also not fine to support policies which supposedly address issues which you don't understand.

You know, experts aren't always going to be someone you've heard of. If someone is banned from editing on Wikipedia, there's probably a good reason for it.
Right back to your flat earth ways.They are all very, very different fields.
Well no, it's because I have the humility to know that I don't have any research worth publishing. We've already talked about how publishing scientific papers means very little.
All science relies on experiments. The type of experiment may vary, but it's still all experimenting. It's one of the fundamental parts of the scientific method.
I can't believe you have the audacity to say this after your comment on experiments.
No buddy, that's you.
Well yeah because linguistics isn't really science. Though I wouldn't be surprised that if the stuff about linguistics on Wikipedia is true but you just don't agree with them.
I highly doubt that.
You're really reminding me of Sunflowers when he constantly bragged about being a philosopher and we all just were uneducated.It's probably because you don't agree with it.
Thank you for the obfuscation. You can become an expert as well. Study physics and read research and summaries, like the IPCC report, which includes a simple summary for policy makers and a technical summary.
A brighter sun would lead to a feedback loop as well. Easy to understand: Warming -> more water vapor (Clausius-Clapeyron equation). Type of forcing does not matter.teo123 wrote: As far as I understand that, no. The warming because of the Sun getting brighter is not predicted to lead to a feedback loop.
For my argument it is not necessary to know all the details. It is enough to know there had been ice ages, so quite big changes. To explain these you need to assume feedback mechanisms.teo123 wrote: As far as I understand it, we know next to nothing about the history of the temperature of the Earth before the late 19th century.

The decrease in these specific models is the initial reaction, but emissions were already rising before there is data available. The infrared radiation has only been measured since 1970. Therefore, there is no outgoing infrared data for the initial rise in greenhouse gas emissions. The observation are consistent with an increasing greenhouse gas forcing, if one does a spectral analysis.teo123 wrote: But this hasn't been observed. In fact, the infrared radiation from the Earth is increasing.
There is a consensus, that greenhouse gases are responsible for most of global warming. The best estimate is, that the whole warming is anthropogenic. Uncertainty is due to unknown aerosol forcing. The anthropogenic attribution is highly certain. This is the summary you can find in the IPCC-report.teo123 wrote: But, as far as I understand it, there is no scientific consensus the greenhouse gasses we emit are what's mostly responsible for global warming. Scientists agree it's at least partly responsible, and that's all.
The data is adjusted for know errors and for statistical inhomogeneities, which are due to non-documented changes in measurements, like relocation of stations are changes in equipement. The raw data were not taken for climate research but for weather estimates. Therefore, they have to be corrected. The global warming estimate from the raw data would be bigger, than from the adjusted data. By looking at the continental US, you are cherry picking.teo123 wrote:warming is indiscernible even when you look at the raw [snipped] of the long-term temperature records. In fact, there appears to be a cooling trend.
Now, the apparent cooling trend is probably due to the time of observation bias and it disappears once you correct for it, but that doesn't change the point that the warming is indiscernible unless you are looking at the ocean temperatures or satellite data.
