Earth's mass extinctions | Peter Ward

[@KeeganIdler]

The reason CO2 concentration will get too low, is that CO2 eventually becomes fixed in the ground. Our tissues for example are buried before they can decompose. Our carbon does not return to the air. The example that he spoke of in the video was fossil fuels being trapped. This carbon could not be released until we found it and mined it.

[@arturoeugster2377]

Not at all, co2 cannot be fixed in the ground, it is strongly absorbed by cold water, because the solubility increases rapily with decreasing water temperature, peaking at the salt-water mixture of the ocean (35 ppm) - 2C.

Problem with both the co2 and impact extinction event hypothesis is that they do not account for either the radioactive isotopes (iron 60 in polar ice and sea floors for example) or the nuclear fission trails found in both rock and bone. Those glass beads he mentioned are also found on the moon. Again with fission trails. You don't get that from volcanic activity or from impacts or bacteria.

[@karhukivi]

I have two scientific objections to this hypothesis. (1) Far more SO2 is released by volcanoes - you can smell it, the typical smell of sulphur - and SO2 reacts with H2S (hydrogen sulphide) to produce water and elemental sulphur, which is why some sulphur deposits are mined by locals in volcanic craters, at tremendous risk to their health, I might add. (2) H2S is released in "black smokers" volcanic vents on mid-ocean ridges and these vents are host to many marine animals who thrive there and seem to derive their energy from the gases released from the vents. People used to write a book to launch a career, perhaps a TEDx talk is now the way to go!

[@arturoeugster2377]

George, I agree with your observation that elemental sulfur is deposited. We did aerial survey in the Cameroon and had a single clear day over Mount Cameroon and the crater rim was yellow. I have one question: is CO2 also released in small quantities in and along the mid-ocean ridges?

[@karhukivi]

@@arturoeugster2377 CO2 is released by many, if not all volcanos, and it is often measured as an indication of the activity of a "dormant" volcano. I presume it is also released by undersea volcanos, but I don't know offhand of any references to that.

[@arturoeugster2377]

@@karhukivi Thank you for Your quick reply! That means that CO2 is continiously released from the earth's interior, as well as from the subducted ocean floor melting under the continents containing crustatian residues ( CaCO3 ) on the pacific rim volcanos. When released from undersea volcanoes, CO2 is in liquid phase and dissolves into the ocean water (not dissociated)

[@karhukivi]

@@arturoeugster2377 There are different views on how much CO2 is released - is it more or less than all the CO2 produced by human activity, but the amounts suggest that the Mantle contains a lot of carbon as well as water in the mineral lattices.

Because I think life is the most stable reaction to the environment at its origin, I think it is more stable than Ward suggests. It's stability is why life is more stable than virtually anything else except some zircon. Since the origin,the atmosphere has changed completely, the land because of plate tectonics has completely changed, and the water has been sterilized many times over through underground vents. Life alone is the most stable reaction to the environment.

[@mrmaciejm]

I agree. Mass extinctions happen when the changes in environment happen so fast that the organisms don`t have enough time to adopt to these changes and be able to survive. These changes may be happening because a meteor impact or because of the rapid climate change, but some species survive, because it`s capabilities to adopt to these changes are higher than the rest of species. And now I ask a question: Will we adopt to climate change or we will try to stop it?

First off Venus is too close to the sun (for us) to live on even if the atmosphere was right. Secondly, life originated on our planet at a time when the temperature and atmospheric conditions would be currently considered "uninhabitable to life".

[@europaeuropa3673]

Russians confirmed the 800 F surface temperatures on Venus are due to the high atmospheric pressure (90 times that of Earth) from the probes they landed on Venus. It is not due to CO2 because the sun's infrared cannot even penetration the thick atmosphere to heat the surface. It is the surface heat (from the sun) radiated back to the atmosphere of Earth referred to as the Greenhouse effect...........it doesn't exist on Venus.

That was from lack of oxygen, not CO2.

[@kevinbaker4164]

This link points out the misunderstanding: achemistinlangley.net/2016/04/10/on-carbon-dioxide-toxicity/ Water can be toxic and fatal if absorbed in such large quantities that it disrupts blood chemistry, . A human can also drown in water from lack of oxygen. Those are two separate things, though there is no reason why both couldn't happen at once, to varying degrees. For example the blood chemistry effect of drinking too much water could cause someone to fall unconscious into water and drown. Just like that, CO2 can be toxic and fatal if absorbed in such large quantities that it disrupts blood chemistry. One could also "drown" in CO2 (so to speak) if there was no oxygen available. Again, both could happen at once, which is probably what happened at Lake Nyos. CO2 is more dense than the average density of the other gases in air so it sinks. The blood chemistry problem can make a person unconcious within 1 minute if they breathe air that is 10% CO2, even if it also contains 17% or more oxygen. Then when they fall to the ground where at 30% or greater CO2 concentration and less than 15% oxygen, both fatal effects can take place with immediate coma, convulsions and death. The analogy between water as a toxin and CO2 as a toxin isn't perfect with one being a gas and the other a liquid, plus the mechanism by which they get absorbed into the body is different, but it illustrates that a substance can be harmless in small doses and be harmful in different ways in higher dosages. One of the most important practical tips to get out of this is that it is a bad idea to hyperventilate before "free diving". That is because the body uses the concentration of CO2 in the blood rather than lack of oxygen to determine if the body is 'hungry' for air. If that mechanism is tricked by hyperventilating the brain could run out of oxygen before triggering the air hunger response, and the free driver suddenly becomes unconscious, even though they were thinking up to the last second that they were OK, and not yet desperate for air. Another example: On the Apollo 13 mission the astronauts had to retreat to the LM after an explosion. The LM had enough oxygen, but the CO2 scrubbers were insufficient for all the astronauts. They would have died, not from lack of oxygen but from the toxic effects of CO2, unless they managed to retrofit the CO2 scrubbers, which they did with a lot of help from mission control.

nuclear fusion is expected to be created by the year 2030, maybe even sooner, but once that happens carbon based fuels could easily be eliminated fusion is just too powerful. Some people may ask what we will run our cars on because fusion can't be used in a car engine, but we can generate electricity from fusion at a power plant and use that to power an all electric vehicle that won't have any emissions. climate change won't really be an issue once fusion is figured out

[@simonpetrikov3992]

I don't think so but we do need breeder reactors and other more efficient forms of nuclear fission power to lower fossil fuel demand like coal, Coal produces more fallout being burned than in a nuclear reactor meltdown.

[@kimweaver3323]

No, coal plants do release radioactive isotopes, but not the most dangerous sorts in any significant amounts. A properly operating nuke plant DOES release less radioactive material than a properly operating coal plant. But compared to a melting reactor or a spent fuel bundle cooling pool fire or prompt criticality event will emit FAR more dangerous radioactive material. Fusion has always been 20 years away and always will be, so the joke goes.

We’ve already past the edge. There is enough detrimental gas within the atmosphere that it will rise beyond the border of two degrees without: to put it simply- any humanitarian input, in any place of time. After two; the world that we know will become efficiently self-reinforcing, in the value of warming, and incapability to sustain any form of life imaginable. There is no imposed great-switch comprehensible that could take back the privilege of existential being lost; even less so, not even imaginable to believe the phantasm of a world with any beings if done within thirty years.

We die not trying to truly have some sort of actual conscious existence throughout all of future eternity. * 3 reduced down to 2: a. We truly have some sort of actual conscious existence throughout all of future eternity. b. We don't. And note, two out of the three options above, we die. * 2 reduced down to 1: a. We truly have some sort of actual conscious existence throughout all of future eternity. b. We truly don't have any conscious existence throughout all of future eternity. (And note, these two appear to be mutually exclusive. Only one way would be really true.) And then ask yourself the following questions: 1. Ask yourself: How exactly do galaxies form? The current narrative is that matter, via gravity, attracts other matter. The electric universe model also includes universal plasma currents. 2. Ask yourself: How exactly do galaxies become spiral shaped in a cause and effect state of existence? At least one way would be orbital velocity of matter with at least gravity acting upon that matter, would cause a spiral shaped effect. The electric universe model also includes energy input into the galaxy, which spiral towards the galactic center, which then gets thrust out from the center, at about 90 degrees from the input. 3. Ask yourself: What does that mean for a solar system that exists in a spiral shaped galaxy? Most probably that solar system would be getting pulled toward the galactic gravitational center. 4. Ask yourself: What does that mean for species that exist on a planet, that exists in a solar system, that exists in a spiral shaped galaxy, in an apparent cause and effect state of existence? Most probably that if those species don't get off of that planet, and out of that solar system, and probably out of that galaxy too, (if it's even actually possible to do for various reasons), then they are all going to die one day from something and go extinct with probably no conscious entities left from that planet to care that they even ever existed at all in the first place, much less whatever they did and or didn't do with their time of existence. 5. Ask yourself: For those who might make it out of this galaxy, (here again, assuming it could actually be done for various reasons), where to go to next, how long to get there, how to safely land, and then, what's next? Hopefully they didn't land in another spiral shaped galaxy or a galaxy that would become spiral shaped one day, otherwise, they would have to galaxy hop through the universe to stay alive, otherwise, they still die one day from something with no conscious entities being left from the original planet to care they even ever existed at all in the first place, much less that they made it out of their own galaxy. They failed to consciously survive throughout all of future eternity. 6. Ask yourself: What exactly matters throughout all of future eternity and to whom does it exactly and eternally matter to? Either at least one species truly consciously survives throughout all of future eternity somehow, someway, somewhere, in some state of existence, even if only by a continuous succession of ever evolving species, for life itself to have continued meaning and purpose to, OR none do and life itself is all ultimately meaningless in the grandest scheme of things. Our true destiny currently appears to be: 1. We are ALL going to die one day from something. 2. We are ALL going to forget everything we ever knew and experienced. 3. We are ALL going to be forgotten one day in future eternity as if we never ever existed at all in the first place. Currently: Nature is our greatest ally in so far as Nature gives us life and a place to live it, AND Nature is also our greatest enemy that is going to take it all away.

God does not actually exist and Nature is not biased other than as Nature. Nature does what Nature does in a cause and effect kind of way.

What shall we believe if we can see with our own eyes, there is no one able to cure epilepsy and other sicknesses, but want to tell us they know what happened a billion years ago. Stop experimenting with our oceans, our air, our earth, in ways that make changes and then blame the average population.

Ten years since this video was posted and humans haven't slowed their path of world destruction. The population of humans continues to climb (6.9 B - 7.7 B), extinction of animals and insects (180 species/24 hr) is rising, pollution IS worse, and a large number of Earth's uprite, pink inhabitants seem to think the resolve is to relocate to "out there". Until we can manage ourselves on this planet we should be shrinking in self-abhorrence.

3:27 surface temp on Venus is 800 deg. F not Centigrade. Slip of the tongue.

[@owencampbell4947]

It reminds me of Jim the scientist-ant, who tried to save his world from humans not from climate change, but it was in vain, they kept coming, his worries were bigger than what they could do about it.

I disagree. Let us say I threw a coin into the air and watched it land. Most of the time it would fall on either heads, or tails. On exceptionally rare occasions, it may fall on its side. Now all the conditions that most come together for a planet to have life, heat, ability to block radiation from its heat source, a stable magnetic core, etc are at such odds that even were I to flip that coin a billion times or more, it is not likely to do something so unlikely as to equal such conditions.

plants don't have problems with CO2 they need it. what he said was that concentration of CO2 will get too LOW

[@funkalunatic]

Does anybody know if the graphs/charts or powerpoint is online anywhere?

[@Icix1]

I agree with keeping an open mind, but then again I wasn't the type of person that believed the bolide impact theory in the first place. The more I looked into the issue the more I realized that an impact wouldn't produce the kind of catastrophic global change suggested by the Permian extinction. To wipe out most life on this planet would require huge global issues and life isn't easy to kill. The reason I believe this theory is because it makes sense, not because I'm blindly following theories!

Of course I did! There is a TED website you know. I'm also a TED youtube subscriber

[@Serpreme]

Where is any of the proof? How does it manifest itself in a real tangible way?

[@St37One]

BTW Even so called "global warming deniers" acknowledge that global mean temperatures have been on the increase over the past 40 years (particularly in the arctic). The controversy is really over the significance of this, on the future climate and on what role anthropogenic carbon will play in such a complex system. A political organization that wears its bias on its sleave such as the IPCC, should not be given the default status of an authority.

[@bademoxy]

there's been global warming since the last ICE AGE! perhaps you've heard of it?

[@thephuntastics2920]

Fun fact alarmists deny : the ipcc already admitted that current models from the ipcc 5 report are fundamentally flawed. 2 years ago they published the new datasets for the next report in 3 years. These datasets include a wider spectrum of solarforcing ,right now only uv irradiance set to a constant number is used in the models but particle forcing, xray, cosmic rays etc will be in the next report. All models so far that use the new datasets show a zero to none impact of co2 i.e. humans on the climate. But alarmists dont like science.

[@robotpanda77]

Even on Earth where everything came together just right, in the 1120 billion years since the universe is suspected to have been created life has only existed within a small portion of that. I don't think that by increasing the coin flips through numbers alone you increase the odds of it doing something so extreme as much as one would believe. We know there are many suns in space, but we know little about if they even have any planets. Life in space is interesting, but by no means certain.

[@jackpleb2360]

1120 billion years is way off. The universe is suspected to be 13.8 billion years old. But that is wring too.

There are other planets to go to just use magnetics.

[@AleksoLaĈevalo999]

John- actually given the way global warming "awareness" is being spread I dare to say that it will happen far further into the future than expected, but it will still happen nonetheless.

[@dadsonworldwide3238]

Everything our ancestors passed down has slowly but surley been checked off the list and proven .

[@Icix1]

All theories have the change of being true or false, such is the basic nature of a theory. But some theories happen to be actually right, and are backed up by physical evidence. And right now, there's mountains (literally) of data supporting the idea that Ward is suggesting. It's a more natural explanation for mass extinctions than a huge meteor or some sort of dinosaur plague. It also explains many oddities in the geological and evolutionary record that are unexplainable under other theories!

[@politiek]

80% of oxygen is produced by plankton not by trees. But I do agree that the cutting down of rain forrests in wrong.

[@stefanhensel8611]

Really interesting connection between mass extinctions in geological ages and climate change that's happening right now. It's a shame, however, this video was only recorded in 240p.

[@stevechinz]

What was that thing about correlation and causation? Oh yeah, they're not the same thing. Just because it's a bad idea doesn't mean it was our idea.

[@Jkim239]

So we should just give up? We've got nothing else to do might as well try to save it.

Wow. Ted has fallen off a cliff. There is no longer any editorial discretion in whom they choose to speak.

[@divergentcontrolyourmama]

Are we ever going to get together as one brain and figure out how to fix our current world problems? We need to work together as one and we can beat anything that happens to earth. Peace

[@nathanfstinson9754]

John Benevento The only way we can fix our current problems is when we learn how to be our government! And this will never happen as long as we allow professional party puppet politicians to stay in office for too damn long without a break to live as one of the governed! Thomas Jefferson proposed strict term limits that required Rotation in all government offices elected and appointed! Here’s a little history. Thomas Jefferson was the French ambassador when they finish drafting and ratifying the Constitution! To put it mildly he was very very pissed off that they had totally abandon the Principles of Rotation in Our Constitution! Bottom line! Rotation requires that those who choose to govern after a number of years in government must spend time living as one of the Governed before holding any elected or appointed office again, no paid lobbying and lock the revolving door and throw away the key! Understand Rotation is a learning tool that will help us overtime learn how to be better citizens more informed voters and patriot representatives that have experience living as one of the governed! We The People are the solution!

[@yalnevatekofreedom5096]

Yes, someone in the scientific community putting there hand up and saying; you know what, science is the reason the world is in the state it's in! Had we not lied to people saying one man's theory in darwinism, which we changed the theory from ape to fish so we must be telling the truth; against the holy Lord of spirits, A-Ba creator, whom talks of dinosaur "behemoth" tallest among beast! Mankind's first known writing in Enoch, 40+prophets, countless prophecy that came to pass BC including Noahs ark which is implemented in the side Mt arafat and is the exact dimensions that's written in the word! Had man continued to live in the ways we was supposed to who knows, but nope, the far left had to suck in azazel and try to undo the good works in the free world! But ye shall not prevail, indeed the King's and mighty push for the masses to believe them, for in the end of days it is the King's and mighty that shall perish!

[@yalnevatekofreedom5096]

You can beat anything that happens to earth.. Do you know how delusional that sounds! Why do you think man can stop everything? I'm going to give you a few pointers which man wouldn't stop no matter what: Mother nature's wrath! Volcanic eruptions & Nuclear disaster! And there your big 3 The belief that we can do so shows how ignorant the human race actually is!

[@melopne]

Eternal life, mass extinsions, how happiness can be maximized,... This all seems to me like the most controversial instead of the greatest ideas were selected for some of the 'talks'. Exceptions noted of course.

[@jeremykristoff7756]

But the asteroid wasn't the reason that there was a mass extinction at the end of the Triassic period. Don't get me wrong, there was an impact and it was a huge catastrophe. During that time there was a time of increased volcanism (the deccan traps). it was this and not the meteor that killed the dinosaurs. The dinosaurs were dying out anyways at the time, the meteor impact just sped it along.

[@deviljes666]

you were there ?

[@draco_bane]

why not both? as the cause! A starts B that cause E

[@nibiruresearch]

Mass extinctions occur very often on our planet. They are caused by a recurring natural disaster. These disasters are mentioned in ancient books as the Mahabharata from India and the Popol Vuh from the Maya and others. They tell us about a cycle of seven disasters that separate world eras. Regularly recurring disasters can certainly not been caused by asteroid impacts or volcanic eruptions. The only possible cause can be another celestial body, most likely a planet, that orbits our sun in an eccentric orbit. Then it is near the sun for only a short period and after the crossing it disappears into the universe for a long time. Planet 9 exists, but seems to be invisible. These disasters cause a huge tidal wave of seawater that is pulled over the earth. At the end it covers the earth with a layer of mud, a mix of sand, clay, lime, fossils from sea and land animals and meteors. They also create a cycle of civilizations. To learn much more about the cycle of recurring floods and its timeline, the recreation of civilizations and ancient high technology, read the eBook: "Planet 9 = Nibiru". You can read it nicely on any computer, tablet or smartphone. Search for: invisible nibiru 9
