More evidence vaping is probably terrible

newtboy says...

Part of why I prefer rosin....no solvents, no additives, just heat and pressure to make tasty and toasty goo.
Still not good for me, but there's nothing that's not in pure weed, and way less carbon.

Why Shell's Marketing is so Disgusting

newtboy says...

Almost as stupid as holding the producers of the toxic product AND the misleading or outright false information about it's hazards blameless. Because they actively misled their customers, I give them the vast lions share of blame, but maybe not 100%. There's plenty to go around.

You don't have to live in poverty to abandon fossil fuels.
Not.
Even.
Close.
I bought solar 10+- years back...it paid for itself in 8. It's lifespan is 20+-. I get 12 years of free electricity for abandoning that portion, with no blackouts, no brownouts, and no rate increases.

True, the video could be better at sharing the blame, but it stayed on topic instead, that topic being major polluters greenwashing their mage. I didn't take it as assigning ALL blame to one source, just not allowing the worst offenders to shirk all responsibility for their products.


Every one of these is the likely outcome of any anthropogenic rise over 2-3C because of feedback loops that drive us to 6-12C rise. Only the wars are likely this century, but I didn't put a timeframe on those outcomes. 140 million + will be displaced by just a 3' rise, which is all but guaranteed by 2100 under the most optimistic current projections.
That wipes out mangroves and other fish nurseries, further impacting the struggling ocean food webs. All the while it accelerates as our ability to cope erodes like the shorelines....it doesn't just halt at 3' rise.
The natural food webs on land are also struggling, and are unlikely to survive ocean collapse.

Not just from deforestation, but diatoms are near a point of collapse from ocean acidification. https://diatoms.org/what-are-diatoms. That's over 1/2....and the base of the ocean food web.


Since the IPCC (again, known for overly conservative estimates) now says at current rates we could hit as much as a 6C rise by 2100, and rates of emissions are rising as fast as carbon sinks are shrinking, they're not just a possibility, they a likelihood in the near future....but granted the hydrogen sulfide clouds are far in a worst case scenario future, far from guaranteed.

@newtboy,

Walking backwards to simplify, my main point is that simply blaming ALL fossil fuel usage on the company providing the fossil fuel is stupid and misleading in the extreme. We don't see millions of people willingly abandoning fossil fuels and living in abject poverty to save the world, instead they are all very willing and eagerly buying them and this video lets all those people off the hook. This video lets everybody keep using fossil fuels, and at the same time pointing the finger at Shell and saying it's all their fault. It's an extremely detrimental piece of disinformation.

"explain what, specifically, I claimed that's not supported by the science."
-Complete collapse of the food web
-Wars over hundreds of millions or billions of refugees
-Loss of most farm land and hundreds of major cities to the sea
-Loss of well over 1/2 the producers of O2
-Eventual clouds of hydrogen sulfide from the ocean covering the land
-Runaway greenhouse cycles making the planet uninhabitable for thousands if not hundreds of thousands or even millions of years

Why Shell's Marketing is so Disgusting

TheFreak says...

I had to stop when he showed a pie chart that said 4-8% but the sliver in the chart represented close to 2%.

I'm a supporter of an accelerated move to low carbon emission energy sources. However, this video used too many manipulative tactics and I couldn't even figure out the thesis. Is it, "company promoting itself is bad?" If you're consuming corporate promotions as if it's hard news, then you're failing a basic test of critical thinking skills.

No sir.
I even mentioned one group in America that never adopted petroleum...Amish...and I would counter your assertion with the fact that most people on earth don't live using oil, they're too poor, not too fortunate. 20-30 years ago, most Chinese had never been in a car or a commercial store bigger than a local vegetable stand.

Both customers and non customers are the victims.
Using (or selling) a product that clearly pollutes the air, land, and sea is immoral.

Yes, it's like our business is predicated on rebuilding wrecked cars overnight which we do by using massive amounts of meth. Sure, our products are death traps, sure, we lied about both our business practices and the safety of our product, sure, our teeth and brains are mush....but our business has been successful and allowed us to have 10 kids (8 on welfare, two adopted out), and if we quit using meth they'll starve and fight over scraps. That's proof meth is good and moral and you're mistaken to think otherwise. Duh.

Yes, we overpopulated, outpacing the planet's ability to support us by far...but instead of coming to terms with that and changing, many think we should just wring the juice out of the planet harder and have more kids. I think those people are narcissistic morons, we don't need more little yous. Sadly, we are well beyond the tipping point, even if no more people are ever born, those alive are enough to finish the biosphere's destruction. Guaranteed if they think like you seem to.

Um, really? Complete collapse of the food web isn't catastrophic?
Wars over hundreds of millions or billions of refugees aren't catastrophic? (odd because the same people who think that are incensed over thousands of Syrians, Africans, and or South and Central American refugees migrating)
Massive food shortage isn't catastrophic?
Loss of most farm land and hundreds of major cities to the sea isn't catastrophic?
Loss of corals, where >25% of ocean species live, and other miniscule organisms that are the base of the ocean food web isn't catastrophic?
Loss of well over 1/2 the producers of O2, and organisms that capture carbon, isn't catastrophic?
Eventual clouds of hydrogen sulfide from the ocean covering the land, poisoning 99%+ of all life isn't catastrophic?
Runaway greenhouse cycles making the planet uninhabitable for thousands if not hundreds of thousands or even millions of years isn't catastrophic?
Loss of access to water for billions of people isn't catastrophic?
I think you aren't paying attention to the outcomes here, and may be thinking only of the scenarios estimated for 2030-2050 which themselves are pretty scary, not the unavoidable planetary disaster that comes after the feedback loops are all fully in play. Try looking more long term....and note that every estimate of how fast the cycles collapse/reverse has been vastly under estimated....as two out of hundreds of examples, Greenland is melting faster than it was estimated to melt in 2075....far worse, frozen methane too.

You can reject the science, that doesn't make it wrong. It only makes you the ass who knowingly gambles with the planet's ability to support humans or other higher life forms based on nothing more than denial.

Edit: We are at approximately 1C rise from pre industrial records today, expected to be 1.5C in as little as 11 years. Even the IPCC (typically extremely conservative in their estimates) states that a 2C rise will trigger feedbacks that could exceed 12C. Many are already in full effect, like glacial melting, methane hydrate melting, peat burning, diatom collapse, coral collapse, forest fires, etc. It takes an average of 25 years for what we emit today to be absorbed (assuming the historical absorption cycles remain intact, which they aren't). That means we are likely well past the tipping point where natural cycles take over no matter what we do, and what we're doing is increasing emissions.

You asked at least 3 questions and all fo them very much leading questions.

To the first 2, my response is that it's only the extremely fortunate few that have the kind of financial security and freedom to make those adjustments, so lucky for them.

Your last question is:
do those companies get to continue to abdicate their responsibility, pawning it off on their customers?

Your question demands as part of it's base assumption that fossil fuels are inherently immoral or something and customers are clearly the victims. I reject that.

The entirety of the modern western world stands atop the usage of fossil fuels. If we cut ALL fossil fuel usage out tomorrow, mass global starvation would follow within a year, very nasty wars would rapidly follow that.

The massive gains in agricultural production we've seen over the last 100 years is extremely dependent on fossil fuels. Most importantly for efficiency in equipment run on fossil fuels, but also importantly on fertilizers produced by fossil fuels. Alternatives to that over the last 100 years did not exist. If you think Stalin and Mao's mass starvations were ugly, just know that the disruptions they made to agriculture were less severe than the gain/loss represented by fossil fuels.

All that is to state that simply saying don't use them because the future consequences are bad is extremely naive. The amount of future harm you must prove is coming is enormous, and the scientific community as represented by the IPCC hasn't even painted a worst case scenario so catastrophic.

Why Shell's Marketing is so Disgusting

newtboy says...

What say you to those who grow their own food, produce their own power with microhydro, solar, and or wind, (or only buy renewable energy, possible in California) and drive electric vehicles or bicycles when they drive?

What about those who still pollute, but offset their carbon usage by buying credits/planting trees?

Can they blame the problem on the companies who supply destructive products and the junk science that tricks gullible ignoramuses into believing they aren't destructive...or do those companies get to continue to abdicate their responsibility, pawning it off on their customers?

I mean, your position seems to be if you assholes wouldn't buy the lead painted products, we wouldn't be selling it to toy companies and producing studies claiming it's safe....so it's your fault your child is brain damaged....or the same argument over opioids, your fault you listened to your doctor and got addicted, then turned to heroin, not your doctor who told you the pills weren't addictive, certainly not the drug company who told your doctor they were safe, right?
Fortunately, courts don't think that way, just ask Johnson and Johnson.

Yes, customers bear some responsibility for what they buy, but not nearly as much as the sellers, especially true when the sellers advertise by lying about the dangers. When companies lie about their products dangers, they make themselves 100% responsible for their damages.

I'm gonna have to stop at 100 companies being responsible for 71% of green house gas emissions.

If the criticism is deceptive practices, don't start with deceptive statistics of your own. It's awful easy to blame Shell for all the greenhouse gas emissions of the gasoline they sell. It's wonderful to not have to take personal responsibility for your act of buying that gas for your own transportation, for the manufacture of your own food, for the transportation of that same food to your supermarket. Better still, the gas and electricity used to heat and cool your home can be blamed on the coal and power companies too.

Videos like this are part of the problem by abdicating our own responsibilities and pawning it off on someone else. Stop making this worse while pretending to care about the problem.

Diatoms: Tiny Factories You Can See From Space

newtboy says...

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.

https://scripps.ucsd.edu/news/key-biological-mechanism-disrupted-ocean-acidification

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".

The First Extinction of 2019 Has Already Happened

transmorpher says...

It's pretty clear the governments can't get their shit together, so it is up to us as individuals to drive the change.

If you want to do your part to combat climate change, then any reduction in products that come from animal farming is going to decrease your carbon (and methane) foot print.

e.g. Go for the bean burrito with guac or tahani dressing, instead of a beef and cheese burrito.

Go for the coconut/soy/almond ice cream instead.

Watch the COWSPIRACY documentary on Netflix, and look up Dr. Richard Oppenlander speaking to the EU parliament.

Distracted Cop Hits Cyclist

Digitalfiend says...

I’m shocked the cop didn’t try and say the cyclist ran into him and blew the stop sign or something. So, at least the cop was professional (or inexperienced) enough to admit his guilt and not try to screw the cyclist over. That’s going to be an expensive replacement though. Looks like an upper end bike, with Di2 (electronic shifting $$$), and carbon wheels, which will probably need to be replaced as well (at least the front). I’d say that bike could be $5k-$8k. This is why I’ve started riding with a video camera front and rear. You just never know when you might need clear evidence, especially as a cyclist.

DOLKEN SPISER SURSTRØMNING!!!!

TRRazor says...

It's called Surströmming and it's essentially fresh hering put in strong brine, which causes the fish to ferment over the duration of 5-6 months.

During this process it produces acids, sulfits and carbon dioxide which all contribute to an obviously disgusting smell.

Usually it is only eaten outside and the can is opened far away from the dining table.

Hydrogen - the Fuel of the Future?

Stormsinger says...

I've always found it annoying when people refer to hydrogen as a new "fuel", especially when they're referring to hydrogen produced by electrolysis. Using electrolysis means that the theoretical limits are that you can get as much energy -out- of burning hydrogen as you put into splitting the water. The traditional meaning of fuel is the exact opposite, that you can get more energy out of combustion than you have to put into creating the fuel.

TLDR - Hydrogen is an energy storage technology, not a fuel. It competes against batteries, not against carbon fuels.
