Most often its grazing livestock, they like to eat seedlings.

You have wildly mistaken the plain meaning of that statement. They declare their model suggests global warming will drive the loss of carbon from soils - not Trees, or aforestation programs.

Considerable academic studies and literature on this subject exists. Recent capture rate from current global forestation is estimated to be approximately 2.5 GtC/year. Current global carbon stock of forests is estimated to about 861 GtC [1] ( virtually twice that hastily sourced figure for total plant life even without those assumptions about algae etc )

Sequestration of current forests, despite the fact they are currently being depleted rather than maintained or increased is estimated by studies to be equal to about 5% of current overall anthropogenic emissions. [2]

For in-depth advice see Chapter 11 of IPCC AR5 [3]

" Reducing emissions from deforestation; reducing emissions from forest degradation; conservation of forest carbon stocks; sustainable management of forests; and enhancement of forest carbon stocks (REDD) consists of forest-related activities implemented voluntarily by developing countries that may, in isolation or jointly lead to significant climate change mitigation. REDD was introduced in the agenda of the UNFCCC in 2005, and has since evolved to an improved understanding of the potential positive and negative impacts, methodological issues, safeguards, and financial aspects associated with REDD implementation.

A study is not really required to confirm that wooden constructions contain and retain their carbon. Even over many hundreds of years the wood in Tudor houses is chemically stable (without preservatives - as long as it has correct ventilation)

Studies may look into possible mistakes or optimizations that could be made, but the basic material reality is evidenced in plain sight.

Vegan ethics are not based on the innate ethics of animals. It aspires to make the most of our human judgement and adaptability/invention, which few if any animals posses similar power to recognize and realize ideas and effects.

The poet Percy Shelley wrote most idealistically but also intelligently about vegetarianism, this small section of a poem contrasts a human caretakers attention to the behavior of wild animals:

  She lifted their heads with her tender hands,
  And sustained them with rods and osier-bands;
  If the flowers had been her own infants, she
  Could never have nursed them more tenderly.

  And all killing insects and gnawing worms,
  And things of obscene and unlovely forms,
  She bore, in a basket of Indian woof,
  Into the rough woods far aloof,--

  In a basket, of grasses and wild-flowers full,
  The freshest her gentle hands could pull
  For the poor banished insects, whose intent,
  Although they did ill, was innocent.

Medias treatment of of different subjects is not randomly balanced in the way you assure. Clearly, positions which are more popular with readership require better treatment than less popular ones, and positions which are popular with advertisers have to be treated most respectfully.

This was an interesting point which I missed at the time. However this situation would only occur extremely rarely in the normal running where the timestep is set small enough to produce reasonably accurate/continuous behaviour. Basically a state is so intricate and detailed that a coincidence of that kind is difficult to envisage, among multiple bodies, holding space and velocity values. And since going forwards or backwards in time always produces a single solution, (rather than multiple solutions) the idea of multiple plausible inputs still seems reliant on rounding error to me or numerical oddities which get more unlikely the more precision and smaller timestep is employed.

I don't agree with that statement for "every teenage kid ever". Most kids appreciate separation from adult attention and accompanying concerns, responsibilities, passions, conflicts...

When a boundary is set at 18, its true that many youths approaching that age will look with great interest beyond it. But child friendly networks are important and valuable to children, while they can be children.

I asked as an aside to the matter of control group - what is considered "given" about "the method of measurement" ?

According to this professional medical trial, the recorded ASD scores are "based on the Childhood Autism Rating Scale (CARS) rated by a professional evaluator"

You should have specific knowledge of that evaluation in order to criticize it as relying on "subjective questionnaires" and shouldn't introduce doubt by simply stating something as "given".

Can you clarify what you are saying about the method of measuring results?

But the results are very strong. In the treatment group, almost 1 in 5 patients went from severe autistic symptoms to normal (clear). And almost 2 in 5 patients went from severe to mild.

This begs the question, is any other treatment known to produce such strong results?

Gracile Chimps (bonobos) eat "fruits, nuts, shoots, stems, pith, leaves, roots, flowers and tubers. Mushrooms are occasionally eaten, and invertebrates such as termites, worms and grubs make up a small proportion of their diet."

- their brains are JUST AS BIG as their carnivorous cousin species. So we have a direct comparison between two very closely related great apes that strongly indicates no evolutionary brain growth advantage of carnivorous diet.

This theory seems to have a single example of an exceptionally large brained predator to claim that predation enables exceptionally large brains - humans. Humans are omnivores - traders, cookers, testers, diversifiers - some human cultures don't eat any meat - and they don't all have little heads as a result.

Ive always liked butter and fatty cuts btw, (from well treated hence healthy livestock) but I'm not buying into this pop-sci that eating extra will feed my brain, or that this is what separates our kind from the dumb herbivores - meat fat feeds almost exclusively my paunch ! :]

Just looking now.. Mice have similar brain/body-mass ratio as humans. There is no strong (or visible) distinction in brain size between carnivores and herbivores in these comparisons:

https://en.wikipedia.org/wiki/Brain-to-body_mass_ratio#Compa...

I don't subscribe to New Scientist's trick title or the theories of nutrient limited mammalian brain evolution.

Compare brain size of carnivore species with herbivores - there is no overt division in average or max brain size. Generally, herbivorous mammals seem to evolve brains just as large as carnivorous ones. Elephants, orangutans, gorillas grow big brains on a vegetarian diet.

If predator diets contain a special surplus of evolutionary-brain-growing nutrients, a few predator species should manifest that claim ~ besides our own artful and fire cooking one.

I do see floating point as like automatically compressed integers, but unlike simulations such as, Conway's game of life, the operations in a physics simulation produce real number values even if we begin with integer state, due to square roots and divisions mainly. I think whatever strength of integer or floated precision used to store results, it will never be possible to tell whether a certain parameter was eg. 328480284374964325 or 328480284374964326. And we need to be able to tell exactly what the input state for any output state must be, in order to have reversibility.

Im not sure. Simulated observers could also observe the direction of time progression; that orders in the past become irrecoverable to them is a mechanistic result of infinite precision not being preserved from one moment to the next.

In a physical simulation, you can't simply set the timestep to -1 to recover previous states for the sole reason that each step adds inaccuracy to the model by way of rounding error.

Like this saying "There is nothing in the form of the laws of nature at the fundamental microscopic level that distinguishes a direction of time." There is nothing in the simulation which prefers to step time by 1 or -1 , but the unavoidable rounding error means it can't step exactly backward. I guess its intimately attached to the fact it cant step exactly forward.

This is why the shattered virtual object wont rearrange perfectly going backwards - it didnt smash perfectly when it was going forward.

I had an idea for making previous states recoverable by applying extra rounding between every timestep, but now I suspect this will not entirely work either, as some least significant imprecision occuring during the timestep will still occasionally trip the more significantly rounded 'interstep' state values, irrecoverably.

About 10 years ago I got the same urge to find or make maps to visually detail humanities conditions. An ostentatious write-up of the idea survives here [1]

I imagined a wiki like effort to crowd source data that scores regions for 5 "Domains of Human Circumstance"

-------

Labour : opportunities, conditions, demands and rewards of productive endeavour

Food : calories, nutrition, contaminants, variety, taste

Material Environment : air & water quality, land quality (toxicity, civil engineering, architecture, ecology)

Social Environment : access to education, entertainment, arts, media, therapists, medicine

Private Environment (shelter,clothing) : allocation, facilities, privacy, preference, private architecture/furnishings, quantity

Physical Security : statistical hazard from criminal predation, military trauma, political/economic upheaval

-------

The category scores would be rendered in colored combinations on maps in a manner which importantly would not average out distributions, so that a region with many people living with low scores and others with high would not deceptively appear as equivalent to everyone with middle scores.

I've regretfully never made any progress on it.

With some personal interest and research I've judged for two decades, (before the IPCC managed to reach consensus) that the potential economic performance of wind and solar is constantly under-estimated and this belief, (admittedly partly intuitive) has year after year been proven true. Even while lacking investment programs of trillions of dollars into R&D which would have been entirely sensible and affordable, proven by greater amounts spent on conflict in the name of security.

I find it beyond justification or excuse how major official forecasters can year after year be so vision-less and pessimistic. We can make floating deep-sea wind farms - and floating solar. We can make better and better batteries and storage facilities as soon as dispatchability and curtailment are close to being a significant cost in a handful of places. Cost of renewable energy has cruised downward with tepid incentives provided by governments. It can plummet within years of serious international public investment in R&D.

There's really no excuse for persistently pessimistic predictions like this [1], from major and professional industry forecasters -

Besides climate change, we also have a huge problem with natural habitat and species destruction. Its really quite irrational to ignore the opportunity for combined solutions.

Its irrational to continue to neglect natural systems in a world where their capacities to sustain diversity have been overloaded by anthropological targets.

The operating system perhaps, but not this particular device driver :)

That is the situation for any driver.

This discussion is under a nonsense test report and headline btw. The car was moving slowly, around what could easily be identified by gps and vision as some sort of test track or empty lot, with varied and inconsistent markings and no other traffic in sight.

From the very first sentence of the article: "...a new graphene-based film that can absorb unpolarized incident light striking it over a wide range of angles up to 60 degrees."

I am quite wary of this kind of thing, but fine graphine dust should be very similar to fine graphite dust of which plenty of experience already exists. Graphite has the same structure as graphine, only less orderly.

Yeh that's the plain meaning. They will be referring to a particular sensor type. Amazement is no cause to say the claim is "unreal"

They mean 30 times as sensitive ie. sensing 1/30th as much stuff. That's what "a factor of n" means btw. Maybe you had in mind "a power of".

I think the life experience of farmed sheep tends overall to be a little milder than wild mountain goats, although they are herded up several times a year which they don't much like - they are bred to be quite cool. Most seriously their lambs are separated and sent to slaughter, and eventually the adults are too if they don't fall ill outside. The slaughter operation is the most problematic and the stress could be reduced alot if it could be arranged on site. In the wild predation on herds and flocks is routinely very traumatic as well.

My major concern with sheep farming is that it is done at an intensity which keeps their ranges quite barren of flora. Tree and bush saplings and many native plants cant withstand grazing levels so ranges which could reforest and be more fertile wild or semi-wild habitats, end up tundra-like despite having much more potential for diversity, conservation or sustainable productivity.

Regarding "ethically produced meat" - I have the sense that if we can arrange for livestock conditions better than their typical experience in nature, then animal experience is overall improved to some degree. If that is arranged then the more animals we can do that for, the more gross experience is improved over the natural level (which due to extant harshness is not all that hard to better) We should also for animal keepers own feelings and experience at work, regulate that animal suffering is reduced to a hard minimum.

Its paradoxical that we can't try arrange this for actual wildlife which is often as much in conflict with its neighborhood as it is at peace, or the wild systems will break down, by removing pressures, saving young from predation etc.
