For what species? ... citing beneficial results of global warming and climate change is meaningless unless you can identify the species which will actually benefit.
Does it matter? Let's use, for purely egocentric reasons, homo sapiens. But, given that the climate conditions which are optimal for human beings will be optimal for a large amount of other species too, it will not be a big difference.
It's funny , you can have a very arid environment that can be flooded for a few days due to extreme weather events. ( Central Australia, Western Queensland/NSW are a classic case)
Funny or not, let's not forget that one of the first big empires, Ancient Egypt, has been existed in such an environment.
That would be "total average yearly rainfall", if you are responding to my post.
You posted that exact claim - you argued, directly and repeatedly, that increases in average rainfall meant decreases in aridity.
It would be interesting if there will be at least once some accurate description of what I have written. Here is what I have written:
But, however it is defined in detail, an increase in absolute yearly rainfall will, plausibly, decrease aridity. As usual for such plausible reasoning, there will be exceptions, but they will be unimportant in the average.
So, not directly but plausibly, with exceptions. Lies, repeated lies, iceaura's posts.
Nothing prevents you from proving this, it is simple, for every claim a quote from the research and the reference to the article containing it. Once you have read all this, this should be simple for you.
I even posted an example, one dense with information and citations and so forth about AGW - against my better judgment and declared rule. Never again.
In other words, you refuse to give any evidence. Thanks for clarifying this. The reason for this is obvious: You have no such research. Whenever you post some real research, you fail to prove your point, and it appears that you are the loser. As with these thresholds: You seem to think yet that these thresholds will result in some abrupt changes in time. some time everything remains almost unchanged, and then comes the threshold and everything changes. But this abrupt change is only a local effect, on the larger scale only borders between different ecosystems change continuously all the time. After such a defeat, your reaction is quite natural: Never again.
Every sentence in that paragraph is wrong, individually and collectively - starting with the most flagrant mistake, which I addressed first, which was your attempt to change the article's findings about thresholds into findings about aridity.
First, at this point I was commenting your text, as quoted. Then, I have simply considered various possible interpretations. Of course, only one interpretation can be correct, so if one considers various interpretations, all except maybe one have to be wrong by default. To interpret this as an "attempt to change" is simply defamatory.
To repeat. There is no "20% more arid" involved - the article's findings are consistent with as much as 100% of the landscape becoming more arid; that number will prevent you from making mistakes. If you don't like it, maybe 60% more arid? 80% more arid?
Now read again what I have written. Have I questioned that the sentence you have written is compatible with 100% of the landscape becoming more arid in the second part, which takes into account that that you have mentioned the thresholds? Not. I have simply clarified, giving an example, what would falsify my expectations:
So 20% crossing some threshold toward more arid, and 40% crossing some threshold toward less arid would be also inside of what I expect.
Does your sentence exclude this particular example? No. Does the article exclude this particular example? No. If you think otherwise, quote the part which falsifies this particular case. Else, the claim that the article is in conflict with my expectations is wrong (or at least not supported by anything).
You used the word "threshold". It was the wrong word. It had to be the right word, because you were claiming familiarity with the concept. You are not familiar with the concept.
You claim so, without presenting any evidence for this. And you obviously will not present any evidence for this, given your "never again" after suffering such a humilation.
How would you know?
You haven't figured out what my claims are yet, and you have more or less completely failed to comprehend the article. You have posted no evidence of even having read it.
I simply go to the point where you have mentioned (in a quite unscientific way, I would guess to make it more difficult for me to find it), the Berdugo et al., Science 367, 787–790 (2020) article to see what you extract as the bad news from this article:
The bad news is that about 20% of the land surface of the planet will likely cross one or more of those thresholds before 2100 CE - that's the AGW researchers's data supported most likely prediction, given current trends - and there will be little warning - the thresholds are apparently fairly sharp.
The reality is that the process will be a continuous one, with the borders of the ecosystems changing continuously, and the sharpness of the threshold leads only to a sharp border on the ground between the different ecosystems. So, there will be a warning all the time, from the start, because these borders on the ground move in an unwanted direction.
(The reality is different, the Earth became greener during the last decades, so it seems that actually those borders move, in the average, in the other, positive direction. But, of course, there are also some parts of the world where they move into the bad direction.)
Which brings up the question of why you guys are posting about AGW at all. What does American fascism gain by sending its minions out to trash AGW research?
I'm posting because it seems to me that the actual climate panic is unjustified. I do not doubt (and care) that there is a warming and if humans are at least part of the cause of this warming. But I see no base for considering this as a catastrophe. I have now collected some of the arguments at
https://ilja-schmelzer.de/climate/. Given that such panics are something very dangerous for the societies where they happen, I think it is important to present and distribute counterarguments. I'm in the fortunate situation that I don't have to fear a negative response by the panicking society, given that I'm independent as a researcher, don't depend on getting a job, and, moreover, live in a country where the climate panic actually plays no role. So, I can simply ignore the "AGW denier" label as well as the "minion of American fascism" label.
I post in a forum full of alarmists to see what they can present to support the panic. As a scientist, I recognize that I may be wrong in my considerations, so that I would like to see reasonable objections to correct, if necessary, my argumentation. Up to now, they have failed to present something serious. The most interesting example was the study
Burke, M., Hsiang, S.M., Miguel, E. (2015). Global non-linear effect of temperature on economic production. Nature 527, 235-239, where the following describes the method (emphasis mine):
We quantify the potential impact of warming on national and global incomes by combining our estimated non-linear response function with ‘business as usual’ scenarios (Representative Concentration Pathway (RCP)8.5) of future warming and different assumptions regarding future baseline economic and population growth (see Supplementary Information). This approach assumes future economies respond to temperature changes similarly to today’s economies - perhaps a reasonable assumption given the observed lack of adaptation during our 50-year sample.
