I'm a bit slow on the uptake: I've only just remembered that, in Russian, its name would be Pravda.

The clerk was a little slow on the uptake but made up for it in performance.

Diatoms, and other phytoplankton, are incredibly sensitive to ocean PH and CO2 levels. This can be another feedback loop already in action.
As fewer diatoms photosynthesize, more CO2 goes unused, raising the concentration, lowering the numbers and health of phytoplankton, allowing more CO2 to go unused, raising the concentration, .....
Every molecule of CO2 added to ocean systems removes one molecule of carbonate, which is necessary for the uptake of iron among other processes. By 2100, surface carbonate is expected to decrease by up to 50%. That may well be below the levels diatoms can tolerate.

If phytoplankton goes, so does the food web. They are the base. If the ocean food web collapses, eventually the bacteria that eat dead sea life will create huge clouds of hydrogen sulfide that cover the land, poisoning any still living organisms there. This has happened before, but on a much longer timescale, with near life ending results for earth.

Hydrogen Sulfide, Not Carbon Dioxide, May Have Caused Largest Mass Extinction. ... "During the end-Permian extinction 95 percent of all species (and >98% of all biomass) on Earth became extinct, compared to only 75 percent during the KT when the dinosaurs disappeared,"

A better title might be "diatoms, the tiny glass shards that support all life on earth, are struggling".

I want to know what effect global dimming has had. It's a no brainer to think less light=less nutrient uptake.
Temperature also helps regulate growth rates, and it's changed.
Interesting about co2 making each plant larger with no addition of nutrients. Reminds me of growing redwoods in New Zealand....they grow astonishingly fast there, but the wood is useless because it's so soft.

You mean apart from the explanation that the speed required to run a marathon is close to a flat-out sprint for most people, and that the maximum speed that you can sustain over two hours depends on the three factors that they explained in the video? It was discussed around 2:10 in the vid.

The handful of people have physiology that gives them unusually high oxygen uptake, lactate thresholds, and running efficiency.

It's slightly clickbaity because Nike... and despite serious cheating their attempt on the sub-2 hour marathon to sell shoes failed by 26 seconds.

p.s. The Grauniad had an article on what the rest of us can learn from these elite runners https://www.theguardian.com/lifeandstyle/2017/may/06/secrets-two-hour-marathon-men-alter-running

"Even with an anti-renewable government".

That's not really true. At both a Federal level (since 2005 under the Liberals) and state level, the government has offered large rebates/subsidies/feed-in tariffs to the public to encourage the uptake of solar power.

I believe some of these benefits are available to private businesses as well.

Interestingly with my global journal access through academia, not anywhere is the article I linked shown as peer reviewed media accessible through the common university publications...must just be a nature journal thing to want to rort people for money no matter what their affiliation.

At first glance, I read this article to mean that the area is a sink in so far as it contains a large quantity of methane, and its 'consumption' or 'uptake' rates are shown in negative values...indicating a release of the gas.

In checking peer reviewed articles through my academic channels, I come across many that are saying pretty much the same deal, heres a tl;dr from just one of them;

"Permafrost covers 20% of the earth's land surface.
One third to one half of permafrost, a rich source of methane, is now within 1.0° C to 1.5° C of thawing.
At predicted rates of thaw, by 2100 permafrost will boost methane released into the atmosphere 20% to 40% beyond what would be produced by all other natural and man-made sources.
Methane in the atmosphere has 25 times the heating power of carbon dioxide.
As a result, the earth's mean annual temperature could rise by an additional 0.32° C, further upsetting weather patterns and sea level."

@newtboy

#1 and #2, fine, if you won't go there to read it's now pasted in full for you:
Arctic tundra soils serve as potentially important but poorly understood sinks of atmospheric methane (CH4), a powerful greenhouse gas1, 2, 3, 4, 5. Numerical simulations project a net increase in methane consumption in soils in high northern latitudes as a consequence of warming in the past few decades3, 6. Advances have been made in quantifying hotspots of methane emissions in Arctic wetlands7, 8, 9, 10, 11, 12, 13, but the drivers, magnitude, timing and location of methane consumption rates in High Arctic ecosystems are unclear. Here, we present measurements of rates of methane consumption in different vegetation types within the Zackenberg Valley in northeast Greenland over a full growing season. Field measurements show methane uptake in all non-water-saturated landforms studied, with seasonal averages of − 8.3 ± 3.7 μmol CH4 m−2 h−1 in dry tundra and − 3.1 ± 1.6 μmol CH4 m−2 h−1 in moist tundra. The fluxes were sensitive to temperature, with methane uptake increasing with increasing temperatures. We extrapolate our measurements and published measurements from wetlands with the help of remote-sensing land-cover classification using nine Landsat scenes. We conclude that the ice-free area of northeast Greenland acts as a net sink of atmospheric methane, and suggest that this sink will probably be enhanced under future warmer climatic conditions.

#3, regardless of if it make's sense to you, and regardless of if it means a 10C warming by 2100, the IPCC scientists collaborative summary says it anyways. If you want to claim otherwise it's you opposing the science to make things seem worse than they are, not me.

#4, To tell them those things would sound like this. The IPCC current best estimates from climate models project 2100 to be 1.5C warmer than 2000. This has already resulted in 2000 being 0.8C warmer than 1900. Summer arctic sea ice extent has retreating significantly is the biggest current impact. By 2100 it is deemed extremely unlikely that the Greenland and Antarctic iccesheets will have meaningfully reduced and there is medium confidence that the warming will actually expand Antarctic ice cover owing to increased precipitation from the region. That's the results and expectations to be passed on from the 5th report from an international collaboration of scientists. Whether that fits your world view or not doesn't matter to the scientific evidence those views are founded on and supported by.

You said the ocean's may be unfishable in 20 years, and the best support you came up with was a news article quote claiming that by 2040 most of the Arctic would be too acidic for Shell forming fish. Cherry picked by the news article that also earlier noted that was dependent on CO2 concentrations exceeding 1000ppm in 2100, and even that some forms of plankton under study actually faired better in higher acidity in some case. In a news article that also noted that the uneven distribution of acidity makes predicting the effects very challenging. If news articles count as evidence I then want to claim we'll have working fusion power to convert to in 5 years time from Lockheed Martin. I'll agree with your news post on one count, the world they talk about, where CO2 emissions continue accelerating year on year, even by 2100, is bad. It's also a bit hard to fathom with electric cars just around the corner, and if not solar and wind, fusion sometime before then too, that we'll still be using anywhere near today's emissions let alone still accelerating our use.

by 2025 it's estimated that 2/3 of people worldwide will live in a water shortage.
And you link to a blog, and a blog that provides exactly zero references to any scientific sources for the claim. Better yet, even the blog does NOT claim that the access to water will be limited because of climate change, the blog even mentions multiple times how other forms of pollution are destroying huge amounts of fresh water(again with zero attributions).

Here's the IPCC best estimates for 2100 impacts regionally:
http://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter14_FINAL.pdf

You'll find it's a largely mixed bag if you can be bothered to read what the actual scientists are predicting. Just bare in mind they regularly note that climate models still have a lot of challenges with accurate regional estimates. I guess your blogger isn't hindered by such problems though. If you don't want to bother I'll summarize for you and note they observe a mixed bag of increased precipitation in some regions, notably monsoons generally increasing, and other areas lowering, but it's all no higher than at medium confidences. But hey, why should uncertainty about 2100 prevent us from panicking today about more than half the world losing their drinking water in 10 years. I'll make you a deal, in ten years we can come back to this thread and see whether or not climate change has cause 2/3 of the world to lose their drinking water already or not. I'm pretty confident on this one.

Northern India/Southern China is nearly 100% dependent on glacial melt water, glaciers that have lost 50% in the last decade
Lost 50% since 2005? That'd be scary, oh wait, you heard that from the same blog you say? I've got a hunch maybe they aren't being straight with you...
Here are a pair of links I found in google scholar to scientific articles on the Himalaya's glaciers:
http://cires1.colorado.edu/~braup/himalaya/Science13Nov2009.pdf
I you can't be bothered to read:
Claims reported in the popular press that Siachin has shrunk as much as 50% are simply wrong, says Riana, whose report notes that the glacier has "not shown any remarkable retreat in the last 50 years" Which looks likely that your blogger found a popular press piece about that single glacier and then went off as though it were fact, and across the entire mountain range .

http://indiaenvironmentportal.org.in/files/glaciers%20and%20climate.pdf
Here's another article noting that since 1962 Himalayan glacier reduction is actually about 21%.

If you go back and read the IPCC links I gave earlier you can also find many of the regional rivers and glaciers in India/East China are very dependent on monsoons and will persist as long as monsoons do. Which the IPCC additionally notes are expected to, on the whole, actually increase through 2100 warming.

I've stated before up thread that things are warming and we are the major contribution, but merely differed from your position be also observing the best evidence science has for predictions isn't catastrophic. That is compounded by high uncertainties, notably that TOA energy levels are still not able to be predicted well. The good news there is the latest IPCC estimated temps exceed the observed trends of both temperature and TOA imbalance, so there's reason for optimism. That's obviously not license for recklessly carrying on our merry way, as I've noted a couple times already about roads away from emissions that we are going to adopt one way or another long before 2100.

I'm interested now...

Seems that Channel 4 won't pick the show up for series 3 and 4? I wonder it the American uptake by David Fincher will include whatever was planned for series 3 and 4?

I respect anyone's choice to do or not do anything they choose. I thought the same way about it until I started to wonder if I wanted to go to my grave not knowing what it felt like out of some stubborn desire to win an imaginary "drug free" sticker at the moment of my death.

I saw some people who smoked it and were a) not addicted or changed by the act and b) functioned excellently and contributed greatly to society (in the form of music and literature and art). So I tried it, and I'd say it taught me a way to cope with my brain and how it works, so I can fight long term depression.

I'm sorry that he didn't stress that there are absolutely no causal links established either between psychosis or education. I still strongly believe that there will be a link between psychosis or mental illness and the willingness or desire to try it - which in turn would give them medicinal relief and in effect they end up unwittingly self medicating. We know it has medicinal qualities as did our ancestors. I think that the link between poverty and social elements greatly affect the uptake rate, having grown up both in council estate (very poor) areas and middle class areas between parents I can vouch for that disparity personally.

I think it's an obvious logical conclusion, and all I need is evidence to disprove it. Until then I certainly will not apologise for using something that has been of the earth for millions of years over something mixed and concocted by pharmaceutical companies that have documented side effects, overdose risk, and actual addiction.

Reaction times yes, but I think having a sufficient degree of certainty that the correct decision will be made is hard to conceive.

Imagine the legal liability of a clear software failure. Even if average accident rates were lower for automated cars, a clear incidence of failure would be a huge monetary legal risk. Whereas, if legal exceptions were carved out for the likes of Google, I doubt there would be very good consumer uptake.

I would suspect their automation algorithm are highly based on visual inputs. Pre-available GPS mapping data would get them only so far. These visual inputs are hugely variable. The number of different car makes, times of day, weather and road conditions among other things, would make for a incredible amount of scenarios to envisage.

I think voice recognition is very similar, if anything more constrained. The deciphering of combination of pitch, accent and pronunciation is a far simpler and smaller domain that we haven't mastered. That would seem to me to be demonstrable proof that automated cars to the level of reliability we would expect, are currently inconceivable.

CBD possesses sedative properties (Carlini and Cunha, 1981), and a clinical
trial showed that it reduces the anxiety and other unpleasant psychological
side effects provoked by pure THC (Zuardi et al. 1982). CBD modulates the
pharmacokinetics of THC by three mechanisms: (1) it has a slight affinity for
cannabinoid receptors (Ki at CB1 = 4350 nM, compared to THC = 41 nM,
Showalter et al. 1996), and it signals receptors as an antagonist or reverse agonist
(Petitet et al. 1998), (2) CBD may modulate signal transduction by perturbing
the fluidity of neuronal membranes, or by remodeling G-proteins that
carry intracellular signals downstream from cannabinoid receptors, and (3)CBD
is a potent inhibitor of cytochrome P450 3A11 metabolism, thus it blocks the
hydroxylation of THC to its 11-hydroxy metabolite (Bornheim et al. 1995).
The 11-hydroxy metabolite is four times more psychoactive than unmetabolized
THC (Browne and Weissman 1981), and four times more immunosuppressive
(Klein et al. 1987).
CBD provides antipsychotic benefits (Zuardi et al. 1995). It increases dopamine
activity, serves as a serotonin uptake inhibitor, and enhances norepinephrine
activity (Banerjee et al. 1975; Poddar and Dewey 1980). CBD protects
neurons from glutamate toxicity and serves as an antioxidant, more potently
than ascorbate and α-tocopherol (Hampson et al. 1998). Auspiciously, CBD
does not decrease acetylcholine (ACh) activity in the brain (Domino 1976;
Cheney et al. 1981). THC, in contrast, reduces hippocampal ACh release in
rats (Carta et al. 1998), and this correlates with loss of short-term memory consolidation.
In the hippocampus THC also inhibits N-methyl-D-aspartate (NMDA)
receptor activity (Misner and Sullivan 1999; Shen and Thayer 1999), and
NMDA synaptic transmission is crucial for memory consolidation (Shimizu et
al. 2000). CBD, unlike THC, does not dampen the firing of hippocampal cells
(Heyser et al. 1993) and does not disrupt learning (Brodkin and Moerschbaecher
1997).
Consroe (1998) presented an excellent review of CBD in neurological disorders.
In some studies, it ameliorates symptoms of Huntington’s disease, such
as dystonia and dyskinesia. CBD mitigates other dystonic conditions, such as
torticollis, in rat studies and uncontrolled human studies. CBD functions as an
anticonvulsant in rats, on a par with phenytoin (Dilantin, a standard antiepileptic
drug).
CBD demonstrated a synergistic benefit in the reduction of intestinal motility
in mice produced by THC (Anderson, Jackson, and Chesher 1974). This
may be an important component of observed benefits of cannabis in inflammatory
bowel diseases.

I don't know what you know, but just in case, and for the record... I was found innocent of all charges that weren't dropped at the onset. I wasn't even there. I have multiple witnesses that placed me at Trinity Lutheran Church Bingo Night until 10:00PM, and I have the Old Spice gift pack and case of Depends that I won to prove it. I have no idea how she got my number. Ask her press secretary. I will have no further comments on the matter.
