How The Dinosaurs Actually Died

newtboy says...

“Witnesses”? 😂 I have some questions for them.

There’s actually more evidence the asteroid wasn’t the major dinosaur killer…the KT boundary layer, created by the asteroid dust and charcoal from global fires is NOT full of dinosaur bones. If one event killed 75% of species and 95% of all biomass, that geological layer would be absolutely full of fossils, but it’s not…it’s nearly empty, but the layers preceding it show a steady decline in animal populations long before the final death blow.

Yellowstone, the American super volcano, is overdue for a similarly disastrous eruption.
Our grasp of volcanology is far too tenuous to claim we would have a million years of warning before a similar major eruption. We might get no warning at all. Surprise eruptions aren’t abnormal even with all our monitoring…and the strength of eruptions is almost always a surprise.

The acidification of the ocean that preceded the other climate-caused extinction events is occurring today. Once diatoms and plankton can no longer create their exoskeletons the ocean food web dissolves, then the land food web dissolves, then clouds of hydrogen gas start erupting from the deep ocean when bacteria consume the billions of tons of dead ocean life, further poisoning the oceans and atmosphere. Yes, that will likely take hundreds or even thousands of years to play out, but the food webs are already falling apart from other pressures before the plankton even fails. Interesting unprecedented times are ahead.

Special Effects for "War Of The Worlds" (1953)

BSR says...

SPOILER ALERT

As it turned out in the end we learn the aliens died because they were not vaccinated.

A true-fake story.

The Martians on Earth are eventually killed by earth-borne bacteria, of which their immune systems couldn't cope due to having destroyed diseases on their home world of Mars.

After the recent IPCC climate report an old 'Newsroom' clip

newtboy says...

*doublepromote someone else finally telling the truth, even if it is just a fictional tv character. I’ve been saying the same thing since around 2000. If we went all in, halted all co2 emissions and all methane emissions 20 years ago, and invested in methods to catch and sequester what we already emitted, we might have avoided the tipping point where we are no longer in control….but instead we increased emissions every year, flooring it towards that cliff and hitting the nitrous button.
*quality if inconvenient truths

That tipping point was reached well over a decade ago when methane started to melt out of permafrost and the deep ocean where it has been frozen for eons. It’s capable of causing warming >80 times as much as co2 short term, >25 times as much long term, and is boiling out at rapidly increasing rates. Pre 2006 it’s estimated around .5 million tons per year…2006 it was measured at 3.8 million tons…by 2013 that was up to 17 million tons with the trend increasing. More recent estimates are hard to find, but it’s agreed that as temperatures climb not only are hydrates melting much more rapidly, bacteria are also accelerating decomposition in the thawed permafrost, and they emit methane. The Arctic is warming up to 5 times faster than the average global temperature. It’s likely over 50 million tons per year by now if not much higher.

Shakhova et al. (2008) estimate that not less than 1,400 gigatonnes (Gt=1 billion tons) of carbon is presently locked up as methane and methane hydrates under the Arctic submarine permafrost, and 5–10% of that area is subject to puncturing by open taliks. They conclude that "release of up to 50 Gt of predicted amount of hydrate storage [is] highly possible for abrupt release at any time". That would increase the methane content of the planet's atmosphere by a factor of twelve in one shot….game over.

Bear in mind, 1 cubic meter of hydrate contains >160 cubic meters of methane gas at atmospheric pressure.

The amount of increase from bacterial emissions in rotting permafrost is debatable, but even the lowest estimates are insurmountable.

This is only one of dozens of KNOWN feedback loops already in action, and there are definitely unknown feedback systems we can’t predict.

This does not mean there’s nothing to be done, we can still mitigate the damage somewhat, maybe slow the rate of change enough that some animals and plants more advanced than bacteria survive long term. It does mean a massive >99% culling of humanity, a total shift in civilization from a money based civilization to one focused on survival, and likely an unavoidable mass extinction rivaling any previous extinctions.

Solving the Mask Shortage in Huntington Beach

newtboy says...

Sorry, 1.5-2m is not really a safe distance without a mask, it's the average distance infectious droplets travel from normal speaking. Coughs and sneezes can spray infectious droplets 23-27 ft before they evaporate. The distancing guidelines are based on older studies of bacterial meningitis, not Covid 19. Bacteria are way easier to kill than viruses.

Mauru said:

This is so fucking weird for a number of reasons:

- Even the dudes handing out the masks don't seem to use them correctly - you need to cover your nose

- Arguably, wearing a mask on a beach or outside is not really that important as long as you stick to social distancing (1.5 to 2m). It's when you enter crowded or often-frequented places (stores, subways, etc) when they become a factor

Is this whole thing really that politicized atm? Scary...

O.C.- The Florida Of California

luxintenebris says...

y'all heard of pandora's box? facial recognition is evil - in every sense of the word - that if it becomes reality, it will become a nightmare.

'covid marys' is a nice term. typhoid mary was a carrier of a deadly pathogen - herself be unaffected - that spread the bacteria that infected 53; killed 3 (one of those killed was the daughter of the woman who hired her as a cook). the parallel is obvious.

newtboy said:

That's why I support using facial recognition to identify these irresponsible inconsiderate ignoramuses and create a database any hospital can use to deny them Covid care, and that responsible people who get infected can use to identify and sue any Covid Marys.
If they insist on putting everyone at risk over their belief that it's not dangerous, they should be forced to live with any repercussions that might arise.

Just a reminder about soap, water, and hand washing

Sagemind says...

They never answered the question at all.

The question was "How do air based dryers spread pathogens?"
Not, "How much bacteria grows when don't use soap?"

I'm still left wondering where the bacteria is coming from when I use the dryer, in comparison to the paper.

Just a reminder about soap, water, and hand washing

noims says...

Since you've tagged coronavirus it's worth noting that (as far as I know) soap breaks down the oily lipid membrane and actively kills the virus, whereas with bacteria - which is what this video's testing for - the soap usually just drags them off your hands and down the sink.

Hence the whole 'wash with soap for 20 seconds' thing relating to this outbreak.

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".

Kurzgesagt - Is Organic Food Really Better or is It a Scam?

newtboy says...

I recently saw a news piece that said in America there are standards for "organic" vegetables fruits and grains, but any fish can be called organic because there is no standard at all.

To be fair, GMO is a bit of a nonsense term as well, technically encompassing everything from crops selectively bred for taste and yield to those with various animal and or bacteria genes spliced in. I wish there were GMO labels and levels, telling us the method of modification, the source of the new genes if any, and even the expected benefits and hazards so we could make informed choices. I still can't believe the ballot proposition to require such labels in California failed.

ChaosEngine said:

Part of the problem with “organic” food (nonsense term, all food is organic by definition) is the fear-mongering around GMOs.

GMOs are going to be a big part of how we feed a population of 7 billion plus. Between the increased yield and lower requirement for pesticides, they have undeniable benefits.

The Virus That Kills Drug-Resistant Superbugs

Spacedog79 says...

Worth mentioning at the end that bacteria may become resistant to licin from a phage eventually, but as far as I'm aware bacteria cannot become resistant to phages themselves because the phage evolves alongside the bacteria.

Could You Eat So Much That Your Stomach Explodes?

Mordhaus says...

Actually, it doesn't burst so much as it ruptures in a small tear. Doctors state you can actually 'feel it go'. The tear doesn't dump all the food, it just releases bacteria into your system which kills you in a few hours if not treated.

The video is correct that it is almost impossible for this to happen in normal situations due to the brain inducing a gag reflex if you continue trying to eat. There are some situations which prevent people from following that reflex.

Bulimia can actually train the body to resist the gag reflex and the constant purging can help a full stomach to tear. Documented cases exist where bulimics have died due to stomach rupture.

People who have been starving for a long period of time can eat more than they can hold. Numerous cases of POW's during WWII, that were presented with large quantities of food after being starved for long periods of time, were indicative of stomach ruptures.

Fortunately if the rupture is caught in time, apparently with emergency surgery and treatment it is not likely to kill you.
