You have all the information you need to know that you haven't followed the research, read the studies, or comprehended any of the arguments. You get that information from your own experience of your own life.No, I have no information of this type. I have only claims of some alarmist,
Once again you describe how your thinking goes haywire and leads to your posting Republican Party memes and propaganda feeds, often word for word, on a science forum. Do you expect sympathy?So, I simply thought, without researching, but based on common sense, that salination is not something which becomes more problematic with AGW. Then I have found that, instead, more precipitation (predicted by AGW) even improves the situation, and this happens even if the additional rain is volatile, and most of the water flows away without being used for plant growing
Once again you explain your posting of Republican Party memes, falsehood and error and baseless slander just as we find on Fox News and promoted by Republican "think tanks" etc, - and it's the same explanation you have posted before:The odds that what I say is correct are quite large, given that several people here strongly oppose what I say, but nobody has been able to present evidence in conflict with what I said.
I have, of course, knowledge about the research I have seen, the studies I have read, and I comprehend the arguments proposed. For example, your "argument" is to repeat many many primitive lies many many times.You have all the information you need to know that you haven't followed the research, read the studies, or comprehended any of the arguments.
From alarmist who lie about me all the time? Of course, not. I expect hate, given that they are unable to present any arguments against what I propose, and all they can do is to repeat lies nobody seriously believes.Do you expect sympathy?
Don't worry, those few people tricked by the alarmists believing that nonsense but with some remains of scientific thinking will give me what is necessary to correct possible errors. You will not, of course, because you have simply nothing to present, this became finally clear during this discussing, where it became quite obvious that it was you who has not read the paper.You will never know how idiotic that "common sense" of yours is, because you will never know 1) how and why and when and where the researchers expect increased loss of agricultural land due to salinization under AGW, or 2) what the researchers expect the "increased precipitation" of AGW to be (more volatile in timing and distribution, almost entirely torrential in quantity, significantly harmful to agriculture on average).
It becomes even more and more obvious that you don't even know that horrible Rep Party's media feed, you use it simply as a name for something evil. But I'm too lazy to check this.But to be fair: your posting is a quite good, very reliable representation of the Republican Party's media feed on scientific topics.
Thanks. Let's see. Most of the salination problems mentioned in the article coming from climate change itself are related to the rise of the sea level, thus, a local problem of the river deltas. They can be handled by building dikes, see here. That means, this is the usual alarmist trick of assuming humanity is doing nothing, not even the elementary things like increasing dikes. Then, the article mentions salination problems which are simply human-made. Like shrimp farms, which like saltwater, so that the nearby groundwater becomes salty and damages other agriculture. Or more use of water for agriculture upstream, which leaves less water for the river deltas.https://www.sciencedirect.com/science/article/pii/S2210600611000086
Just one of many, many studies showing that climate change is causing freshwater supplies to become saltier, not less salty. Moreover, as the planet heats up and lakes evaporate, it forces people to use salinated groundwater instead. But hey, maybe if we make sure Kremlin TV keeps saying positive things about climate change, it'll become reality.
I have cared about this a little bit more, given that the description given in your paper suggested that indeed there could be some non-trivial mechanism which increases salination problems:The replacement of deep-rooted native perennial vegetation with shallow-rooted annual crops and pastures has caused water tables to rise, resulting in waterlogging, dissolution of salts in the soil profile, and movement of these salts to the soil surface.
Dryland Salinity and Ecosystem Distress Syndrome: Human Health Implications. EcoHealth 4, 10–17, 2007.
The main reason for the increase of the groundwater level is the irrigation, which is necessary given the aridity of the region, and that the irrigation water also contains salt is the main cause of salination. But, indeed, the removal of the plants with deep roots, which were able to access and use the deep groundwater, also leads to some increase in the groundwater level. And if the ground above the former groundwater level is salty, the groundwater can become more salty too.In Australia with the removal of the natural vegetation, the amount of water entering the water table (called the recharge) has increased and the rising groundwater level has dissolved the accumulated salt within the soil. Eventually (after many decades), the groundwater level reaches the surface, bringing the salt with it. This results in the death of all but the most salt-tolerant plants with consequent changes to other parts of the ecosystem.

Whatever, thanks for the reference. It is a much more valuable contribution than dozens of postings by iceaura.The amount of water flowing into the Sacramento and San Joaquin river delta is the single most important determinant of salinity at the export pumps, and the amount of inflow has been shown to be largely determined by hydrology. During rainy years, the average salinity at the pumps is low. The average electrical conductivity – a measure of salinity – at the banks pumping plant for the 1983 water year (one of the rainiest on record) was 276 lS/cm, corresponding to 431 mg/L. In the critically dry 1991 water year, electrical conductivity at the same location averaged 589 lS/cm, corresponding to 920 mg/L.

Read the arguments. instead of crying We have thousands of years even in the most alarming scenario, and the effect is below 70 m, which leaves quite a lot land to live even without any new dikes:FFS! The ice caps are melting at ALARMING rates, no problems, we’ll build dykes!!!!
I have never made any comments about burgers and chips. As usual, my opponents cannot do without defamation.Rainforests are being strafed for burger meat and fucking palm oil to cook chips.
I love burgers and chips!
Because you say so? I prefer the facts on the ground. They already work nicely in the Netherlands.btw, dykes ain’t gonna work.
Once again we are confronted, by you, with clear evidence and sound argument provided by you, conclusion that you have seen little or no research, read few or no studies, and comprehend none of the arguments involved, in AGW scientific efforts.I have, of course, knowledge about the research I have seen, the studies I have read, and I comprehend the arguments proposed.
The extra precipitation from AGW has been found damaging, not beneficial, to agriculture; the salinization of agricultural land under AGW has little to do with the salinity dilution or suppression of river water via torrential rain and flooding, and so forth.And, as usual, it has given me some additional advantage of more precipitation: It decreases the salination of the river water too:
They cannot be handled by building dikes in most places (the Netherlands being a rare circumstance which may not be able to keep up anyway), and in the few that might benefit no one has the money or - if the latest findings on glacial flow and melt does reflect the trend that analysis found long ago, as seems likely - the time.Thanks. Let's see. Most of the salination problems mentioned in the article coming from climate change itself are related to the rise of the sea level, thus, a local problem of the river deltas. They can be handled by building dikes, see here
You don't know the facts on the ground.Because you say so? I prefer the facts on the ground.
Such as rising sea level in low areas - wet rice farming on river deltas and flood plains, say - the major food supply of about a fifth of the population of the planet.But, while one cannot exclude such effects completely on theoretical grounds, they matter only under very special circumstances.
The article I handed you reported the finding that regions adding to about 20% of the land surface of the planet were expected to be converted to such regions, with little warning, intermittently. And yes - that is predicted to make them not very good for agriculture - something you proceeded to deny.These regions are, therefore, not very good for agriculture anyway.
Of course they will, as I have repeatedly noted: you rely completely on the media feeds from American rightwing authoritarian sources, the media wing of American fascism, which has been backing the Republican Party for a few decades now, and they have been happy to supply you with all the means (Party memes, designed for campaign season, mostly) you find necessary. (That the American Civil War was fought over tax code amendments, not slavery; that child labor cannot be involved in a stable equilibrium of a market capitalist economy; that grad students and other vulnerable scientists adjust their topics and findings to please liberal and deep state funding sources and publication access, excluding good news or reassuring discoveries accordingly; etc).Don't worry, those few people tricked by the alarmists believing that nonsense but with some remains of scientific thinking will give me what is necessary to correct possible errors
You have never once fact-checked anything, on this forum, except Syrian troop movements. Not even when handed the relevant research directly. Simple laziness hardly explains such firm rejection of physical reality.It becomes even more and more obvious that you don't even know that horrible Rep Party's media feed, you use it simply as a name for something evil. But I'm too lazy to check this.
Different from CptBrk, who gives a link to the paper, iceaura intentionally hides the links. That means, he wants to prevent that I read those articles. So, just to clarify the rules: References to scientific papers have to be given in the usual format, else they don't count as evidence.(byw: the intro and foreshadowing in the latest Science magazine issue provides informatio on the topic of "volatility", as does related online commentary concerning Atlantic magazine's latest issue and forthcoming treatments by both these magazines in June.
There is no necessity to teach Australians elementary things. They know such things themselves.There's a large region in Australia that illustrates the topic - it went from years of record drought and heat and wildfire to massive flooding in a matter of weeks. If you want to entertain the Australians here, you might try showing us how to handle that by building dikes.
Fine, what's the problem? I do not pretend to be a specialist for all that - I simply question the alarmism, by looking at the arguments presented by the alarmists and answering them. Up to now, they have presented nothing which forced me to abandon the basic idea that some warming is even positive, that the time scale is slow enough for humans to succeed with adaptation. There was not even a necessity to hope for a moderate scenario, for the problems I had to consider even the worst case scenario was not that horrible. The techniques to handle the problems are well-known and old, my expectations have been initially based simply on common sense, but for many problems I have already improved this.The extra precipitation from AGW has been found damaging, not beneficial, to agriculture; the salinization of agricultural land under AGW has little to do with the salinity dilution or suppression of river water via torrential rain and flooding, and so forth.
That is knowledge routinely available for years now, in the research studies and reports and arguments.
Feel free to explain what prevents building dikes. Remember, the basic technology is rather simple: Take a lot of stones, gravel, sand and so on and throw this into the water at the place where you want to have the dike. Of course, situations where you, like the Dutch, can gain a lot of new ground out of what is the sea now are rare. In this case, you need large areas of the sea which are shallow. But nothing prevents to build dikes at the shore, not for getting new land but only for protecting the existing land.They cannot be handled by building dikes in most places (the Netherlands being a rare circumstance which may not be able to keep up anyway),
The time scale is 3-4 m per century in the worst case scenarios. So, time is certainly not the problem. Money is not really a problem too. Here I have even made a rough estimate of the most important part of the costs of such a project (the material of the dike and the transport).and in the few that might benefit no one has the money or - if the latest findings on glacial flow and melt does reflect the trend that analysis found long ago, as seems likely - the time.
Learn to read. The remark was not about this.Such as rising sea level in low areas - wet rice farming on river deltas and flood plains, say - the major food supply of about a fifth of the population of the planet.
In your fantasy only. In reality the very method they used to get these results defines also a method to get a warning. You forgot to mention how many arid regions will be converted to non-arid ones because of the predicted increase in precipitation. And, of course, no iceaura posting without an explicit lie. I have no reason to deny the triviality that if a given region becomes more arid this is bad for agriculture.The article I handed you reported the finding that regions adding to about 20% of the land surface of the planet were expected to be converted to such regions, with little warning, intermittently. And yes - that is predicted to make them not very good for agriculture - something you proceeded to deny.
They are not counted as evidence in the first place. They are information for you, places where you can go to find evidence if you want any.References to scientific papers have to be given in the usual format, else they don't count as evidence.
That's what you do, yep.I simply question the alarmism, by looking at the arguments presented by the alarmists and answering them.
You pretend to be dealing with physical realities, and you don't know any. No "specialist" requirements are involved - the simple, basic, physical knowledge that you pretend to possess is all you would need.Fine, what's the problem? I do not pretend to be a specialist for all that
Not the worst case, the worst case with larger than some small - maybe even single digit - probability.The time scale is 3-4 m per century in the worst case scenarios.
Time is so short that only the very optimistic think we have much of a chance, even with a fully funded internationally coordinated effort backed by every industrial power.So, time is certainly not the problem.
I was unable to get a good estimate - the data and analysis in the article support anything from 0% to 80% (the low end more likely).You forgot to mention how many arid regions will be converted to non-arid ones because of the predicted increase in precipitation.
Yes, it was. That was the point of the reply - to make more clear what your remarks included in regards to physical reality.Learn to read. The remark was not about this.
That is reassuring - the sudden NA methane boost the researchers had noticed a little while ago was scary, because most other sources of methane boost larger than predicted are more dangerous, and bode more ill. It's still only partly accounted for, that boost, but it's no longer leaning so heavily toward armageddon.ased on satellite measurements from May 2018 to March 2019, Permian methane emissions from oil and natural gas production are estimated to be 2.7 ± 0.5 Tg a−1, representing the largest methane flux ever reported from a U.S. oil/gas-producing region and are more than two times higher than bottom-up inventory-based estimates. This magnitude of emissions is 3.7% of the gross gas extracted in the Permian, i.e., ~60% higher than the national average leakage rate. The high methane leakage rate is likely contributed by extensive venting and flaring, resulting from insufficient infrastructure to process and transport natural gas.
Are you sure this would be a satisfactory solution for some 8 - 10 billion people?Climate change... who cares? With oil this cheap, not only can we build enough dikes to stop a flood of Biblical proportions and filter all the salt out from leaching inland, but now we can also start moving everyone into orbital space hotels where they'll be safe from the worst effects of the CO2.
In the actual information revolution, I don't want "any" information, there is enough. The information I want should be scientific information, not alarmist nonsense. Moreover, it should be relevant to my claims. Once you obfuscate your reference, and don't quote it, it is, with a far too high probability, irrelevant.They are not counted as evidence in the first place. They are information for you, places where you can go to find evidence if you want any.
The worst case as considered in peer-reviewed scientific mainstream papers. And this worst case appears to be not catastrophic at all.Not the worst case, the worst case with larger than some small - maybe even single digit - probability.
And that rate would be catastrophic, to human civilization.
It would be catastrophic even if the effects accumulated steadily and evenly, rather than in the sudden crossing of tipping points and quick region-wide metamorphoses now expected as most likely.
As usual, not without a lie. I have never questioned that AGW is much faster than any global natural warming event in the geological record. I compare it with another time scale - the time scale of building the appropriate infrastructure to adapt. Which is much shorter. Look at the infrastructure China has build during the last forty years.The propaganda mongers - such as yourself and other rightwing apologists here - insist on burying that key fact: AGW is hitting ten times as fast as any global natural warming event in the geological record. The homeostatic feedback loops that stabilize ecological responses to global climate change now are failing now - and acceleration is expected.
Fine. That means, except for the case it is in the 0%-20%, the problem of your 20% becoming more arid is only a problem of adaptation of agriculture to new places. I'm quite comfortable with the actual situation where we have agreement about precipitation increasing in the average and the parts becoming more arid as 20%, the parts becoming more wet 0% to 80%.I was unable to get a good estimate - the data and analysis in the article support anything from 0% to 80% (the low end more likely). You also were unable to post that number - despite having much more interest in it, and no idea what was wrong with the assumptions you were making.
In principle not impossible. In some sense, one can even expect this, and it would even reduce the costs of adapation. Namely, the regions where most of the rain comes down are the mountains.(It's almost certainly a small number - increases in torrential rain do not make up for concomitant increases in evapotranspirative deficit during long (predicted) droughts between storms, especially as most of it is likely to fall as torrential increases in currently existing heavy rainfall distributions.
That means the extra rain will be falling during otherwise regular strength and expected rainstorms, mostly where it's already very wet.
The article I was able to find despite your obfuscation. The standard reference in science is something different.You can read about that factor in the article I referred to you, as one of their major findings in agreement with other research.
It was not. Here is the context of the quote you have replied to:Yes, it was. That was the point of the reply - to make more clear what your remarks included in regards to physical reality.
So, this part of the problem (rising sea level) was already handled in the first part of my discussion. Then I discussed a different problem, not related to rising sea level:Thanks. Let's see. Most of the salination problems mentioned in the article coming from climate change itself are related to the rise of the sea level, thus, a local problem of the river deltas. They can be handled by building dikes, see here.
So, yet another lie. Ok, in this case may be not an intentional lie, but simply the inability to understand the arguments discussed in the context.Or, in Australia: [...]
I have cared about this a little bit more, given that the description given in your paper suggested that indeed there could be some non-trivial mechanism which increases salination problems:
[...]
The main reason for the increase of the groundwater level is the irrigation, which is necessary given the aridity of the region, and that the irrigation water also contains salt is the main cause of salination.
[...]
While this effect is completely human-made, and even the papers don't claim otherwise, at least in principle one could imagine such an effect:
[...]
But, while one cannot exclude such effects completely on theoretical grounds, they matter only under very special circumstances.
Such as this one, in which some researchers seem to have tracked down a possible source of the methane boost that has become larger than predicted: https://advances.sciencemag.org/content/6/17/eaaz5120?et_rid=49312811&et_cid=3305920
So, a completely human-made contribution without any causal connection with climate change. Except that it may enhance it for some time.Using new satellite observations and atmospheric inverse modeling, we report methane emissions from the Permian Basin, which is among the world’s most prolific oil-producing regions and accounts for >30% of total U.S. oil production. Based on satellite measurements from May 2018 to March 2019, Permian methane emissions from oil and natural gas production are estimated to be 2.7 ± 0.5 Tg a−1, representing the largest methane flux ever reported from a U.S. oil/gas-producing region and are more than two times higher than bottom-up inventory-based estimates.
I'm not at all predicting favorable weather for farming, I'm predicting weather which allows for farming, if supported with adequate infrastructure.Unfortunately @Schmeltzer has decided to ignore the fact the for agriculture to be successful consistent, light to medium rain fall is ok but not torrential rainfall, massive hail and 200 kph winds. I am unsure why he is predicting favorable weather for farming when everything is pointing to just the opposite.
News: Czech republic is facing worst drought in 500 years...
Gee, what a pity.... I have never questioned that AGW is much faster than any global natural warming event in the geological record. ... .
Are you sure this would be a satisfactory solution for some 8 - 10 billion people?
Gee, what a pity.
Perhaps you should...
from nasa:
"When scientists started to analyze the paleoclimate evidence in the Greenland and Antarctic ice cores, they found that the record also supported Milankovitch’s theory of when ice ages should occur. But they also found something that required additional explanation: some climate change appeared to have occurred very rapidly. Because Milankovitch’s theory tied climate change to the slow and regular variations in Earth’s orbit, the scientific community expected that climate change would also be slow and gradual. But the ice cores showed that while it took nearly 10,000 years for the Earth to totally emerge from the last ice age and warm to today’s balmy climate, one-third to one-half of the warming—about 15 degrees Fahrenheit—occurred in about 10 years, at least in Greenland. A closer look at marine sediments confirmed this finding. Although the overall timing of the ice ages was clearly tied to variations in the Earth’s orbit, other factors must have contributed to climate change as well. Something else made temperatures change very quickly..."
