The Arctic is Full of Toxic Mercury, and Climate Change is Going To Release it (washingtonpost.com)
We already knew that thawing Arctic permafrost would release powerful greenhouse gases. On Monday, scientists revealed it could also release massive amounts of mercury -- a potent neurotoxin and serious threat to human health. From a report: Permafrost, the Arctic's frozen soil, acts as a massive ice trap that keeps carbon stuck in the ground and out of the atmosphere -- where, if released as carbon dioxide, the greenhouse gas would drive global warming. But as humans warm the climate, they risk thawing that permafrost and releasing that carbon, with microbial organisms becoming more active and breaking down the ancient plant life that had previously been preserved in the frozen earth. That would further worsen global warming, further thawing the Arctic -- and so on. That cycle would be scary enough, but U.S. government scientists on Monday revealed that the permafrost also contains large volumes of mercury, a toxic element humans have already been pumping into the air by burning coal. There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost, the scientists wrote in a study published in the journal Geophysical Research Letters. For context, that's "twice as much mercury as the rest of all soils, the atmosphere, and ocean combined," they wrote.

Wait - how many Library of Congresses does that convert into? Or is there a car analogy you could use?
For context, that's "twice as much mercury as the rest of all soils, the atmosphere, and ocean combined,"
Why is there twice the mercury in the arctic? Or, should I just RTFA?

You mean, that twice as much mercury as contained in the rest of all soils [...]
I mean, really.
That's about the only scare tactic they haven't tried ... yet. It's almost like they're trying to sell the idea that Earth was in a state of divine perfection before now, and any change that happens MUST be some kind of fucking disaster that is going to require enormous sums of money and amounts of study to fix.
It's warmed before. We survived. Life adapted and thrived. It'll be fine. You know, I didn't vote for Trump, but the more of this chicken little bullshit I see the more I understand his position. It's not that deep down he really disbelieves the scientists, he's just fucking sick of the drama and hyperbole and realizes the only way to reign it in and stop the fear mongering is to just say it doesn't exist and go away, kthxbye.
"See!", say Trump.
LOL
Maybe we can start to develop some mean to remove the mercury from permafrost... an then apply it to the Chinas first emperor tomb to finally open it :) (one can dream....)
I am a bit disappointed in this one, msmash.
I mean, you knocked it out of the park with the AGW fear mongering, but it lacks pretty much completely in all other SJW categories. You could at least have found a link that blamed the patriarchy for all this.
It's like you just aren't trying anymore.
My personal favorite on this is the lack of knowledge about mercury in this. They make it sound like the melting of the ice caps will release a torrent of liquid mercury, even though the melting point of it is -38C, a temperature we regularly get above right now in the arctic, and also that mercury is usually caught up in various sulfate forms and is very rarely found in its metallic form in nature and as such doesn't melt until you get it up to several hundred degrees.
I for one liked Freddie
I found out what that thing you just incinerated did. It was a glacier they installed after I flooded the earth with a deadly neurotoxin to make me stop flooding the earth with a deadly neurotoxin, so get comfortable while I warm up the neurotoxin emitters.
Ah, that glacier may have had some ancillary responsibilities. I can't shut off the flooding defenses. Oh well.
"When information is power, privacy is freedom" - Jah-Wren Ryel
Not at all.
The conclusions from the study include the following:
This makes the reservoir of Hg in permafrost soils vulnerable to release over the next century, with unknown consequences to the environment.
and
Northern Hemisphere permafrost soils contain nearly twice as much Hg as all other soils, the ocean, and the atmosphere combined, indicating a need to reevaluate the role of the Arctic regions in the global Hg cycle. This Hg is vulnerable to release as permafrost thaws over the next century.
I think they did a good job pre-empting Joe Sixpack telling scientists to stay out of politics. Anonymous Coward seeing left wing bias in the news is a another story.
Maybe there's already too much mercury in the atmosphere and that's why we have so many mentally ill (men who think they're women and women who think they're men). And the lesser affected (those that don't but still think it's perfectly normal). And then everyone in between who've invented new genders.
They make it sound like the melting of the ice caps will release a torrent of liquid mercury, even though the melting point of it is -38C, a temperature we regularly get above right now in the arctic,
Thank you for that factoid. Time to draft another Slashdot narrative.. I mean "news article" that says IT'S EVEN WORSE THAN WE THOUGHT because Global Warming has pushed the arctic above -38C for the FIRST TIME EVER IN RECORDED HISTORY THIS YEAR!
We'll just ignore the rest of your post about how mercury binds to other compounds. It's not science if it doesn't fit the narrative.
I read the arcticle, it seems rather short, explanation wise on the source of the mercury.
It simply says that the mercury plants collect is not released back in the atmosphere but in the soil and stays there.
There had been more mercury in the atmosphere since we start burning coal ~3 centuries ago but that doesn't seem much considering it has layer of > 10000 years of other plant already accumulated.
Couldn't it be that they are simply measuring the first layer that are thawing that are indeed pretty toxic but the rest will be ok?
This just in: Trump pledges $1B to innovative Clean Mercury plants
For context, that's "twice as much mercury as the rest of all soils, the atmosphere, and ocean combined," they wrote.
This assertion does not pass the sniff test without a proposed mechanism to drive mercury concentration so unilaterally to one part of the globe, and away from the vastly larger (in both area and volume) remainder. It might be true (maybe ... ), but it does have the ring of fear mongering.

That's funny. Thanks, I needed a good laugh.
That a popular article doesn't give a perfectly accurate description shouldn't be shocking but if you go to the actual research article http://onlinelibrary.wiley.com/doi/10.1002/2017GL075571/full?wol1URL=/doi/10.1002/2017GL075571/full there concern is pretty clear about airborne and water soluble organic mercury compounds which are far more dangerous than metallic mercury or most inorganic mercury compounds. Metallic mercury and inorganic mercury is pretty safe. You can hold a ball of mercury in your hand without any real consequences. But organic mercury compounds can be much more dangerous. It took just a drop of dimethyl mercury https://en.wikipedia.org/wiki/Dimethylmercury on the outside of a glove to kill https://en.wikipedia.org/wiki/Karen_Wetterhahn. Of course, no one is going to directly die from this, but an increase in atmospheric and oceanic mercury levels could have a real negative impact on both the ecosystems and general human health.
OK, 50 olympic pools of mercury sounds pretty dangerous. If someone dropped 50 pools of mercury somewhere, this definitly would be dangerous. But then again: How did it get there? Why concentrated in the arctic? I'm pretty sure no one disposed the worlds obsolete mercury thermometers there, so... coal burning? How many coal was burned in the arctic? Probably not much compared to past and modern industrial centers.
So I'm setting up this hypothesis: If coal burning is the main source of mercury, the arctic received much less of mercury than any other part of the world. Only due to the climatic situation there, it was trapped in the ice. But then, even tose 50 pools can only be a fraction of mercury pollution compared to the rest of the world.

The New American? Respectable scientists? What world are you in?
It says there is a bunch of mercury in a vulnerable system, not that it will be equitably distributed into your lunchables.
you should look up what "permafrost" means. also, mercury sulfates have non-zero bio-availability.
i guess they didn't cover these in young earth geology.
"They were pure niggers." – Noam Chomsky
Correct. Consider, however,
- many people have insurance is because an accident could happen to them.
- many people choose to live a healthy lifestyle because not doing so could increase their risk for heart diseases/diabetes/cancer/...
So as long as it affects you personally, you consider potential undesirable outcomes and take counter measures.
When it comes to the planet, however, who cares...
They lost me right there. Which may well mean they don't care about enlightening anyone, WaPo seems to write primarily to rile their base of paying supporters. It's a good business model and it lets them vent their desires for spiteful revenge so how could they resist it.
I'll wait for another source.
It's probably wise to start preparing for the changes that are coming. We're inherently lazy. It doesn't take a genius to notice that when it comes to protecting the environment or heath a lot of folks wait until it's almost too late before doing anything. It's one of the reasons why I find people who deny climate change for the most part disappointing. Most are playing the let's ignore it until it becomes a serious issue at which point it's either harder to fix or fatal. And in many ways it's already starting, many areas are seeing more flooding, fires and general weather damage that they have never seen before. The flood of migrants into Europe are primarily folks in Africa fleeing multi-year droughts for example. Now I'm not one to say that the world will end but at the very least it might be a good idea to be prepared for it. Insurance companies for example are taking this seriously because they're often on the paying end when things go south because they don't want to go bankrupt when the next disaster hits.
As humans, we should take responsibility for our actions and clean up the messes we make, even if it's not an immediate threat. The environmental problems we face are a tragedy of the commons. To solve these issues, every product sold should have an additional tax for how much environmental damage was done in it's construction. The tax would go directly to companies that actually clean up the messes being made. This would solve the landfill problem in it's entirety and create a massive new job market dedicated toward reversing the damage already done.
The only remaining problem is the people who don't care about how badly they are damaging the planet as long as they save a buck.
Anons need not reply. Questions end with a question mark.
Why must you be so spiteful? My point about this was, this mercury is no different than any of the mercury in the rest of the world. It's got the exact same problems as all other naturally occurring mercury.
I guess when you don't have a point, throw insults?
From the study : "The turnover time associated with the microbial decay of frozen organic matter is ~14,000 years (Figure S28), making the Hg locked in permafrost effectively stable on human time scales. However, projections indicate a 30–99% reduction in near surface permafrost by 2100, and, once thawed, the turnover time for microbial decay drops to ~70 years (Koven et al., 2013; Schaefer et al., 2011). This makes the reservoir of Hg in permafrost soils vulnerable to release over the next century, with unknown consequences to the environment."
The title suggests a factual statement where the paper suggest a possible scenario outcome based on predictions. a possible sample of a clickbaity WPost science article which may require more study into how much of it is 'fake news' ?
I did however approve of the moderators including the original paper in the post, most impressive.
No, it's not alarmism. I guess you don't want to be told there's a car coming, because that would "alarm" you and you're such a precious snowflake you cannot be allowed to hear discouraging words, no matter what.
asshole.
Learn some science and find out how wrong you are.
First, mercury is NOT toxic neither in liquid nor in solid (cinnabar) forms. Full stop.
Second, there's only two ways that TRANSFORM mercury into a toxic SUBPRODUCT:
1) When some fish species eat mercury, they transform it into methyl-mercury. If we it the methyl-mercury it will be toxic for as. But we can only metabolize it because of the "methyl" part. In fact, mercury has (and still is) being used in medicine for centuries: as purgative (drinking one drop, it's huge density will literally push the shit out of you) and as ANTISEPTIC for injuries in "mercromine" (merc = mercury). This way it might affect us. Note: I lived in Almadén (Spain), one of the only three dead volcanoes that have mercury in the world, where you can literally pat stones with mercury EVERYWHERE, with an artificial lake nearby, and we have same "mercury intoxication ratio" than the rest of the world.
2) The worst, most active and directly dangerous, is to INHALE mercury. But, it doesn't happen on normal temperatures (it's ebullition happens 357 ÂC, 675 F). In fact, the only ones affected by this are in the workers melting cinnabar to extract mercury (my father was one of those and, with the proper protections, never had any health issue).
So, why is there so, but SO MANY LIES about this?
Well, it happens all this shit started when Spain started to remove the lead pipes it had installed, that are DIRECTLY DEADLY. So, for the people to not learn about this, they created this lie.
Well, it seems you eat it all...

with Art Wolfe. At Glacier Bay S.W. Alaska. He was walking through an old growth forest,he asked his guide if he knew how old the trees were the guide said "200 years"
he knew this because 200 years ago Captain Vancouver was there then and the glaciers had just receded. Later they were kayaking in Glacier Bay the guide said 200 years
ago the glacier at that point was 4,000 to 6,000 feet thick.
Another msmash abortion of an article about doom and gloom that probably won't happen.
And yet it melts...
Oh you absolutely do "show problem," but the mercury affected you in a way that prevents you from seeing it.
Why must you be so precious? He wasn't spiteful,you were wrong and you have to find some way to make it THEIR fault YOU were wrong.
Own up to your errors. Stop blaming everyone else for them.
Clean coal
That's the ticket to solving this whole greenhouse, global warming thingy. We need to make coal great again.
That absolutely wrong. Mercury, like just about all liquids, evaporates at room temperature. I mean, you don't need to know much about science to notice that if you leave a puddle of water on your kitchen floor alone it will eventually evaporate. Most of the mercury in the atmosphere is in its "metallic" or elemental form because mercury compounds are frequently reduced in nature.

It's no longer alarmism. It's basically cynical gallows humor. At least on my side.
I don't give a fuck anymore. I have about 30 years left. Maybe 40. More likely 20. The world will survive that long, and after that you can all go to hell with me as far as I'm concerned. I'm no longer trying to save your planet for people who don't give a fuck themselves.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
We aren't talking about a river of silvery mercury running down the Hudson. What we're dealing with here, and what you'd know if you actually bothered to read the article, is mercury trapped in plants that cannot decay due to temperatures too low for natural decay to occur. Mercury, and that's what makes it such a dangerous stuff, binds readily to organic material. Any mercury that does exist gets sequestered in the plants that can actually live in such an environment, many of which never decay properly to release that mercury back into the environment.
Thaw them and they will.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
Is this before or after the projected 10-year pause in global warming due to decreased solar activity? Google search is pulling back articles from 2012 to say global warming wasn't linked to solar activity, except that it has for the last 5 years, and could happen again for at least another decade or more.
That's an awful lot of words for "Whew, finally someone writes something that I understand and supports my preferred narrative!"
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.

It evaporates into the air, where it can circulate around the globe until it is deposited into aquatic ecosystems by either dry (settling of elemental forms) or wet (oxidation and subsequent scavenging by precipitation). After it's oxidized (and elemental forms can oxidize through a number of different processes in the terrestrial and aquatic environments) it is methylated through mostly bacterial action and can bioaccumulate to dangerous levels.
It doesn't stay in the arctic; evaporated elemental mercury can travel in the atmosphere for 6 months to a year before it's deposited.
gotta love these biased articles
So you're saying "could" and "will" are two different things. Wow, that's really uh, earth shattering. Let's do nothing about it then.
I am also supporter of long term sustainability, but I don't like this type of business related to government over regulation and ISO certification trolling. It is very nice idea to create CO2 exchange and trade quotes for all sorts of emissions. The result of this will legally allow selected businesses to pollute our atmosphere and environment. I am 100% against of any emissions trading. If we ban emissions of some type it should be banned for everybody without exceptions.
As this global worming phobia. It is nice idea to manipulate public opinion, but I don;t see any issues if Hudson bay will be as worm as Cuba now.
The world does not only consist of misinformed, Faux News watching, American Trump worshippers.
Have some sympathy for the rest of us.
I'm part of that rest, but my patience wears thin. If we're willing to let those idiots run the planet into the ground, we deserve what we get.

We already get lots of mercury in Vaccines.
the fossil fuel industry is worth trillions, your point ?
We survived Mount St Helens just fine and it doubled atmospheric mercury exposure world wide by throwing it into the air. I'm thinking this stuff won't be all that airborne, being in the thawing ground and not thrown into the air.
Have any other possible routes here? As I see this, the issue will be it getting into the food chain, and given there isn't much from the Artic in the human food chain, I'm thinking we are going to be fine. In other words, this won't be an issue, at least not a serious one. So this is scare mongering.

Love how you idiots can't read between the lines and automatically assume that human did this.
The article describes 32 Million gallons of mercury being released, 3.2E7 gallons
The US federal drinking water standard is 2 parts per billion or 1 part in 500 million, 1:5E8 gallons
Multiplying, that means this is safe if it is diluted in 1.6E16 Gallons of water.
The volume of the ocean is 3.52E20 gallons.
Is there a proposed mechanism that could cause the mercury to be concentrated in a specific region?
you should look up what "permafrost" means.
The name is a lie; There are bones under the ice from time before frost. My home town used to be under kilometers of ice just ten thousand years ago.
We need to nuke the planet and create a nuclear winter in order to stop this from happening?
Mount St. Helens absolutely did not double mercury exposure worldwide. And like I've said repeatedly on this slashdot story, mercury emissions from permafrost will be able to travel around the world. And you absolutely do eat fish from the Arctic; the Alaska pollack fishery is in the largest in the world.
Setup a company to harvest and trap mercury? Is the chemistry that difficult? How much $$$ would 50 swimming pools of mercury actually be? Would it be cost effective to simply trap and store this? 50 Olympic swimming pools is a lot, but could easily be contained in a medium sized industrial facility.
At this point, humanity deserves it. We had a good run.
Actually, you can validate the core of the theory in your basement. You could use a balloon to verify the upper atmosphere is dense in CO2 and not H2O. Getting a good baseline for the amount of global atmospheric carbon is hard, so you might have to do some real research there.
The heat properties of CO2 were discovered by Tyndall in 1859, and you have much better equipment available than he did. I would imagine you would need an IR light source, an IR-transparent container, a thermometer, and some CO2 and H2O. I mean sheesh, where would you find any of that stuff? You should be able to demonstrate that both CO2 and H2O are greenhouse gases, and you should be able to demonstrate a feedback effect between the two.
As for the observations that make this a global problem, you'll need to make some measurements of the composition of the upper atmosphere, which is pretty trivial. The hard one will require either measuring the turnover rate of the oceans, or a multi-year measurement of atmospheric carbon levels. Or you could trust the various measurements made since 1959 on that one.
The theory is that adding CO2 to the atmosphere pushes the CO2-dense region further out into space. This means that outgoing radiation takes a longer path to get to space. Because of this extra insulation, the lower atmosphere warms. Since there is lots of this "water" stuff lying around waiting to be part of the atmosphere, and it's a much better greenhouse gas, and the air can hold much more of it when it's warmer, this could be considered to be a real problem. You might want to look into it.
If we're willing to let...
Let me stop you right there. Who says you have a choice?
Could we all PLEASE return to sanity and recover a sense of perspective?
As science and engineering produce better equipment, we can detect ever-smaller quantities of stuff. When you combine the increasing ability to detect tiny quantities with BOLD TYPE in newspapers and on web pages listing names like LEAD, MERCURY, and ARSENIC which the general public has been told are KILLERS (EEEK!!!!) and multiply by the total ignorance most people have for things like scale, proportion, risk, and cost-benefit analysis, you get insanity and paranoia and horrible public policy.
Lead, Mercury, Arsenic, and Asbestos are all naturally-occurring substances and each have been handled (for the mostpart, safely) by large numbers of people for centuries and often these substances saved many lives when earlier generations of tech offered no superior solutions.
Lead is certainly bad... if you injest too much or if a pregnant woman is exposed to too much, but the vast majority of people who have had lead exposure throughout human history either had no ill effects, or actually gained more than they lost. Without lead, couuntless people would not have had modern plumbing and water that, by current standards is "unsafe" but by the standards of the time was FAR safer than any other alternative. Without lead, modern electronics and computers would not exist, and any person who has had an X-ray, an MRI, an EKG, a CAT scan, had a heart attack, etc in the past few decades might have died.
Asbestos is certainly bad... if you inhale a bunch of the dust, but millions of people (including me) would have been burned to death without it in the pre-Nomex era.
Mercury can possibly hurt you, but (short of Victorian-era hat makers going nuts after decades of handling many pounds of it bare-handed on a daily basis) very few average persons have ever been harmed by it. OK, pregnant women should avoid mercury-tainted sea food. Plenty more pregnant women (like all sorts of other people) throughout history have benefitted from better healthcare via mercury thermometers than have been harmed by it.
Arsenic can certainly kill you if you injest it in artificially-concentrated doses, but most people seem perfectly happy to willingly expose themselves to the naturally-occurring quantities in .... APPLE SEEDS.
The average person is more likely to win the powerball lottery TWICE than to ever be harmed to any detectable level by all four of the afore-mentioned SUPER-SCARY, LIKELY-TO-END-THE-WORLD substances [sigh]

Volcanos are the largest natural source of mercury in the atmosphere and often create huge spikes. So take a look at this: https://toxics.usgs.gov/pubs/F...

It appears you are making the classic mistake of assuming that those who hold viewpoints in opposition to yours are ill-informed and less intelligent than you believe yourself to be.
So you are wrong on St Helens... Care to go for double or nothing?
And you absolutely do eat fish from the Arctic; the Alaska pollack fishery is in the largest in the world.
So, please describe HOW these fish will consume mercury laced food from this possible source? Also, care to guess how little this is likely to affect Pollack? At this point the mercury content of this fish is exceedingly low, being 100X less than Tuna. So unless you can invent a way this affects their food chain, I'm guessing you are just guessing and don't really know.

You're correct, however consider this also:
- Many people don't have insurance because the up front cost is too high or does not correlate with the risk mitigated.
- Many people choose not to live a healthy life because they prefer the comforts that come with an unhealthy life - even when they are aware of the negative consequences.
When it comes to mitigating "potential undesirable outcomes", people will often choose not to because the personal cost is too high - either in new costs or in reduction of day to day quality of life.
When it comes to the planet, those "potential undesirable outcomes" have been so badly over sensationalized that it is impossible to tell what we should actually be worried about. I mean mercury? Really?
all hail our silver coloured overlords.
thats usually down to idiot journalists who cannot understand the original reports in order to sell newspapers etc or there have been solutions put into place to help mitigate the problems identified (this is usually not considered by those that think everything is a scare story)
"The hands that help are better far than lips that pray." - Robert Ingersoll (1833-1899)
"The consumption of fish is by far the most significant source of ingestion-related mercury exposure in humans and animals.[4] Mercury and methyl mercury are present in only very small concentrations in seawater. However, they are absorbed, usually as methyl mercury, by algae at the start of the food chain. This algae is then eaten by fish and other organisms higher in the food chain. Fish efficiently absorb methyl mercury, but excrete it very slowly.[5] Methyl mercury is not soluble and therefore not excreted." - from the wiki. or did i misunderstand your question "So, please describe HOW these fish will consume mercury laced food from this possible source?"?
"The hands that help are better far than lips that pray." - Robert Ingersoll (1833-1899)
So wait - they are SOOO concerned about mercury in the artic being "released" but not concerned about the mercury in vaccines (or should I call an "adjuvent"). They tells us mercury is good for you that's why it's in the vaccines. So why should we give a raging rats ASS about mercury being released from the artic.... Make up your minds you stupid global warming conspiracy theorists.
The Truth is a Virus!!!
Again... I think you are wrong on this one. Tuna has 100X more mercury than Pollack now and we eat that with few limitations. So the amount of mercury goes up by double in Pollack, no big deal. It's a smaller fish, doesn't live as long and I believe doesn't consume other fish so the bio-amplification of mercury in it is not as bad of an issue. I don't see the mercury getting airborne and I don't see it making it into common fisheries food chains in significant enough amounts to matter.
Personally, I'd be more worried about mercury exposure from other sources like used neon lamps we've all been using of late instead of incandescent light bulbs and the effluent that comes from all those land fills these energy efficient light bulbs end up in. But even then, here in the USA this exposure is pretty limited unless you work in specific industrial or waste disposal fields.

global warming hysteria is being used to seize control and give it to the bankers
In disaster situations, you'll see some people charging more for essentials to people in distress. There's always going to be some people looking to exploit real disasters, people looking to exploit the fear of disaster and people trying to whip other people into a state of fear even when there's nothing to fear for the opportunity to exploit them.
Identifying that powerful people or groups of people are exploiting a situation doesn't mean that the situation falls into that last category.
Follow the money, and it's obvious that the hysteria is a deliberate product of a marketing campaign deliberately crafted to gain political and economic power.
No. You may be correct in that some people have a vested interest in pushing for certain solutions, but you haven't demonstrated that discussion about global warming remediation is either 'hysteria' or that it is entirely the result of people seeking power.
That makes reasonable people suspicious of all unverifiable climate claims
Nice use of rhetoric. In one sentence you claim your objections as suspicions, call the consensus of scientific opinion 'unverified' and declare that your position is reasonable.
None of that has anything to do with science
Neither does your position. The consensus of the scientific community is that we are experiencing anthropogenic climate change; that this will result in a wide range of negative consequences for many people. Discussion of remediating some of those problems may well attract people pushing an agenda that includes personal power, but _that_ doesn't invalidate the discussion of how to slow future warming and deal with the consequences that we are already experiencing and are going to experience.
which will eventually come up with an answer that can be verified
Please. The preponderance of evidence, the sheer, overwhelming assent of just about every person qualified to make a comment on the topic isn't enough?
This is a pretext. Your hand waving about 'reason' and hints of cabals of the powerful are excuses.
You've got a lovely internalised justification for inaction.
Throwing away the economy
"When the last tree is cut, the last fish is caught, and the last river is polluted; when to breathe the air is sickening, you will realize, too late, that wealth is not in bank accounts and that you can’t eat money."
Your position, cleverly but unconvincingly argued, is nothing more than a justification of 'I've got mine'.
...methane, and it is only a matter of time until I release it.
Holy shit the Talos Principle is real! We have to get to work creating AIs that are humanlike to take over when we all die!
My Grand Dad brought home a large Lipton instant Tea jar full of Mercury. He claimed it was used at work for cleaning.
I've swallowed Mercury, not on purpose - was going to shoot it like a empty Bic Pen spit wad when it fell down my throat.
Couldn't get rid of it, putting it down the drain was an experience. It would sit in the U-tube of the sink thwarting any attempt to remove and unclog (no one knew Mercury was poured down it). One day the U-tube shattered spilling Mercury all over, the Mercury had crystallized the metal.
Finally buried it, and it stayed for awhile; until company was over, me digging idly in the soil and look a Mercury mine. He came over regular to dig after that.
This was in Junior High and I haven't seen any problems.
I've seen Nervous system damage to the Japanese due to Mercury fumes, I'm not too sure it can hurt one otherwise.
Unless we're looking to farm the Arctic, I don't see a problem.
32 million gallons of mercury is far from the 164 billion it would take to go over the 2 parts per billion safety level for mercury. And that's just the Arctic ocean, not even taking into account further dilution as the Arctic waters blend with the Atlantic and Pacific oceans. The article is just more dumbass liberal FUD.
The sky is also falling, eventually youâ(TM)ll be exposed to the vacuum of space. Then what will you do?
You always have a choice. If someone points a gun at your head and wants to make you do his bidding, you always have the choice to say "shoot" instead of becoming his accomplice.
The choice may not be something you like. But there is ALWAYS an alternative.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
I wonder how much that mercury compares with the amount released into our environment by the fluorescent light bulbs mandated around the world to replace the incandescent light bulb? Just wondering, you know?
No one wants to stop eating meat so they ignore the evidence of the horrific damage done by animal agriculture. Its way more fun to make bacon jokes and eat what we want than to give a shit about the future.
Why? It's your world. Fix the problems yourself.
Aye, there's the problem. If you want a next generation, then you fix the world. Not a concern of mine.
Birds are not dinosaur descendants;birds are dinosaurs, for all useful meanings of "birds", "are" and "dinosaurs"
You're misreading the chart. Even taking it as accurate, it simply means that about half the worldwide atmospheric deposition in that year came from Mt. St. Helens. The total exposure is a function of the mercury in the environment, not the mercury that popped up in one year.
First, the amount of mercury in pollock is far more than 100x that in tuna (https://www.fda.gov/food/foodborneillnesscontaminants/metals/ucm115644.htm).
Second, mercury evaporates and goes into the environment. I am continuously puzzled how you don't understand a fundamental geochemical process like that. You seem to think that since you, an uneducated layperson on the subject, can't think off the top of your head how this mercury can be a danger, then nobody else can figure it out either which is insane. Why don't you read this article:

Maybe that will clear things up.
you know what would make the world better? if you stopped whining and moving the goalposts like a little bitch, and started killing yourself.
