If they get bored and stop listening, they'll get confused, won't they? I think they often get bored because they can't follow along, it's incredibly boring to have someone drone on using statistics and measurements you don't grasp and won't remember on a subject you also don't grasp.

I agree, but so far, measurements have consistently been outpacing the estimates, almost never the reverse.

What they tend to do is come from that incomplete data and incomplete analysis to model the absolute best case scenario to dictate policy, not the worst. That's absolutely what the U.N. report does, and it's not clear to most how much is left out, like infinitely better melting models (the measured melting in Greenland is already at the rate not predicted to be reached until 2075 in the UN's published estimations) and feedback loops we already see in action like melting methalhydrates and permafrost, both outgassing massive amounts of methane. Sane policy makers DO assume the absolute worst modeled outcome, then suggests policies to avoid it, at all cost when that worst case is extinction. Since measurements are consistently as bad or worse than the worst case scenario modeled, the only rational thing to do is assume that will continue and plan for the worst....you know, like they taught in preschool, hope for the best, prepare for the worst.

Your house burning down is an unlikely worst case scenario, but I bet you have smoke detectors, fire extinguishers, and support the fire department. Good planning is to assume you WILL have a fire and plan to minimize the damage.
Or, terrorist attacks. The likelihood you'll be killed in a terrorist attack is exceptionally low, but we spend untold billions and sacrifice liberties to combat a worst case but unlikely scenario.

Prudence is the better part of valor.

Edit: as to most problems society faces, I suggest they are likely ALL a function of overpopulation....no question imo when it comes to the apocalyptic problems. Pollution, resource mismanagement, ecological destruction, etc. None would be disastrous with 1/10 the population.

Actually, I'm selling their audience short. When real scientists present the real data dispassionately, I think the average person gets quickly confused and tunes out. Those that dumb it down enough to be understood invariably underrepresent or outright misrepresent the problems. With so many unscientific voices out there trying to out shout the real data for their own purposes, real scientists fudging the data is near criminal because it's only more ammunition for deniers.

Yes, if you or I heard them lecture, we would likely hear that and even more, but the average, unscientific American would hear "taking in more energy than is leaving" as a good thing, free energy. If they explained the mechanisms involved, their eyes would glaze over as they just wished someone would tell them it's all lies so they could ignore what they can't understand fully. These people are, imo, the majority in the U.S.. They are why we need emotional delivery of simplified science from a charismatic young woman who knows her stuff.
Edit: For example, I had read the published summaries of the recent U.N. report saying we had 12 years to be carbon neutral to stay below 1.5degree rise, they were far from clear that this was only a 50% chance of achieving that minimal temperature rise, or that we only had 8 years of current emission levels to have a 66% chance, still bad odds. I understood they were also using horrendous models for ice melt and other factors to reach those optimistic numbers, and didn't take feedback loops we already see in action into account, nor did they make allowances for feedbacks we don't know about yet. The average reader only got 12 years to conserve before we are locked into 1.5 degree. They don't even know that's when known feedback loops are expected to outpace human inputs, making it exponentially harder if not impossible to turn around, or that 1.5 degree rise by 2050 likely means closer to 3 degree by 2100, and higher afterwards.

Mating habits for European swallows?! How did we get from the relationship of climatology and sociology to discussing the red light district?

Ok, but don't discount the factual arguments because they are presented with passion. Ignore the emotion and focus on verifying or debunking the facts presented. Because someone on Fox presents their denial argument flatly and dispassionately doesn't make it more correct.

Yes, I agree, but the point was getting people to listen, read, and fully examine the facts rather than accept the, also emotional, arguments without fact or with incorrect, cherry picked, or misrepresented facts that dominate the discussion on both sides, but mostly on the denier side since facts and data do not support them.

That line isn't blurred, it's been pressure washed away. The emotional arguments are nearly all that's out there, the facts are so misrepresented by both sides...oddly both sides minimizing the problem, the right to ignore it for profit, the left to not overwhelm those wanting to make progress by admitting it's too late.
Note, she mentions the thoroughly reported study that said we must stop emissions in 12 (now 10?) years to stay below 1.5c rise actually said we must make that sacrifice to have a 50% chance at that (and goes on to explain why even that is outrageously optimistic since it doesn't take feedbacks and other factors into account and relies on future generations to make not only the sacrifices we aren't willing to make, but also to clean up/sequester the emissions we continue to emit at faster rates daily).
I have zero problem with the emotion of the delivery if the facts are presented clearly and in totality, which she does better than most if not all professional scientific lecturers....sadly.

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.

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.

Trump, and all other people.
Even then, it's going to be a tough time for life if trends don't reverse quickly. Far more than an inconvenience. I heard (unconfirmed) data that suggests Iceland will lose all of it's ice even if all greenhouse gas emissions stopped today. Enough feedback loops are kicking in sooner than expected that we may be in a runaway situation already no matter what we do.
This business will get out of control, it will get out of control and we will be lucky to live through it.

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 wolf is not at the door, it's inside the house....you keep insisting that's just grandma with those big teeth....new dentures, you say....grandma has always been hairy, you say....wolves don't exist and are fake news, you say.

Once again you misunderstood and misstated the science....12 years (+-) before the feedback loops make reversing the trend impossible, not 12 years until all ice melts, not 12 years before everyone dies. You just can't help but shout your ignorance from the bell tower. Thankfully, most here know just how often you are correct and gauge your comments with that in mind.

Interesting suggestion.

I believe that with 1/10 the population, near today's per capita resource usage would be sustainable....although there would be a necessary time period with net zero or better emissions required to return the atmosphere to "normal" before runaway greenhouse effects and feedbacks turn earth into Venus 2.0. After that, there is an amount of emission the planet can absorb, so resource usage need not be curtailed excessively, but it wouldn't hurt.

I'm all for the lottery system if everyone draws straws, no exceptions except those willing to just move to the reservation voluntarily.
Even a lottery system simply for procreation would do wonders, but remembering the outrage at China for just allowing one child per couple, I doubt that would fly either. Also, it does leave the possibility that the lucky procreators might all be imbecilic morons incapable of following/continuing the plan...we don't want to become a species that is dumber than our pets....or do we?

I think the priorities should be reversed too, what's best for life on earth first, humanity second.

"In the next few decades"?! More like "a few decades ago".
Perhaps if we had started population control in the 80's with the goal of cutting global population in half by 2000 AND did the rest of what he suggests we might have a chance...we did not.

By the time we understood there was a problem there were less than a few decades left to solve it...that was around 40 years ago, and we've done everything possible to accelerate the damage we do on every front since then.

Ocean acidification is happening today, it's getting worse, it's slow to react to change so will continue to get worse even if humans disappeared tomorrow, it has built in feedback loops that have been triggered like melting methanehydrates and sequestered CO2 that are being released faster every single day, and we are increasing the man made causes every year. There is a point where it reaches critical acidification, the point where diatoms can't form their skeletons, and then the entire ocean system dies. That's far worse than the apocalypse it sounds like, not just because 50-60% of our oxygen comes from the ocean, but also because the rotting biomass creates huge amounts of not just more methane, compounding the greenhouse problem and further acidifying the oceans, but also immense amounts of hydrogen sulfide, which spread as huge poisonous clouds around the globe.
We are on our way to a man made Permian extinction, when >95% of all species went extinct and near 99% of all biomass was lost. We will not survive it as a species....and we don't deserve to.

and a *promote and *quality just to obtain some potential feedback.

Hmm, just looked up the case again and it looks like you’re right.

It’s probably still a dumb move, and it shows an astonishing lack of people skills (if someone asks for feedback and you’re going to be highly critical of not only them but the company, do it privately; don’t email the whole company), but he probably didn’t deserve to be fired.

Doesn’t change the facts of this case though.

I wasn't thinking about including YT ad revenue in the economics, but I guess that certainly could be counted and definitely motivate many people.

However, I guess that confirms that it is passion for the work, the machines themselves, and the feedback that are the primary motivators for him. Would probably still be doing these repairs even if YT income / encouraging feedback wasn't a factor, and even without more traditional motivators like plans to resell or use the repaired devices.

I guess the closest parallel would be repairs and restorations for museum displays. There's a financial element there too, but the people doing the restorations do that job more for the love of the objects and seeing them restored.

(edited )

From what i can tell he does this because he's passionate about it and how getting feedback from his videos is what brings him the most joy (his reddit comment). I think it has very little to do with anything financial. Although the yt ad revenue for this video is easily into the thousands (1.6 million views). One of these a week, with those numbers, could easily make him a comfortable living.

The microphone feedback at the 1 minute mark was a sign that something was going to go.... very wrong.

Microphone feedback is always a sign that something is amiss.
