A little doom – Poor Earth

So I have been busy making a compilation list “lock-down mood distraction” from old lists I made many years ago in my “Earth Cycle” hobby. Please excuse spelling and copy/paste mistakes (tried to check but must have missed some)

First I would like to ad Supernovas and a little doom to my100,000 year cycle upgrade

We are in the 6th major extinction which is heading towards its peak and Antarctica is taking us there. Ice-ages (climate) are the most lethal contributor according to history

Extinctions:

650 Mil BC (Climate) – “Snowball Earth” extinction wiped out 70% of sea plants due to global glaciations. (It came close but did not cover the equator)
443 Mil BC (Climate) – The glaciations of Gondwana were responsible for the second largest mass extinction according to studies
374 Mil BC (Climate) – Global cooling with surface temperatures dropping around 8°C and extinct 70% of marine species. This was a prolonged series of extinctions occurring over 20 million years. Evidence of anoxia in oceanic bottom waters
360-280 Mil BC (Climate) – The Karoo Ice-age had extensive glaciations with extinctions on the Gondwana continent, the current Karoo region of South Africa, Australia, Antarctica, India and South America. The Laurasia continent the current Europe, Greenland, Siberia, North America, Kazakhstan and Northern China was believed to be ice free
359 BC (Space) – The Devonian-Carboniferous boundary contain hundreds of thousands of generations of plant spores that appear to be sunburnt by ultraviolet light — evidence of a long-lasting ozone-depletion due to a possible Supernova event
252.28 Mil BC (±11,000 years) (Climate) – The Triassic–Jurassic extinction was Earth's worst Mass extinction that eliminated 90% of ocean dwellers, and 70% of land plants and animals. It lasted less than 200,000 years and corresponds to a glaciations period. Sediment layers with an accuracy of 35,000 years in the Nanpanjiang basin in southern China prove this extinction timeline with a sea-water level decreased for around 80,000 years
Although the Siberian traps started 400,000 years before the main extinction it was a double, maybe triple extinction with the Siberian trap peeking around 500,000 years after the glaciations period of extinctions
The Siberia Traps has the largest known deposited of lava and volcanic rocks on land and lasted for around 900,000 years with the main trap forming in less than 60,000 years
It seems there must have been another event with massif atmospheric changes and greenhouse gas releases as Oxygen (O2) levels dropped from 30% to 12% as the Carbon dioxide (CO2) level was below 2000 ppm) An global upward jump in temperature reach 50-60°C on land, and 40°C at the sea surface (this misery is far from solved, studies seem to prove the ocean extinction 1,5 million years after the Triassic–Jurassic boundary extinction – still can’t shake the comet feeling)
232 Mil BC (Climate) – Durring the “Carnian Pluvial Episode” shock events with four pulses of warming and climate perturbation within a million years led to repeated extinctions. The climates shuttled from dry to humid and back, speculations put the eruptions, in western Canada represented today by the great Wrangellia basalts, as culprit
201-199 Mil BC (Volcanism) – Continental split forming the Atlantic Ocean creating the Atlantic Magmatic Province flood basalts killing 20% of all marine life (seems like volcanism and plate-tectonics are guilty here)
65,5 Mil BC (± 0.049) (Impact) – At the K/P boundary Antarctica had a subtropical climate and flora, complete with a marsupial fauna. Work at Seymour Island, Antarctica showed two separate extinction events near the Cretaceous-Paleogene boundary 150,000 years from each other. 75% of plant and animal species on Earth became extinct
Although impacts normally has a larger dating error the Chicxulub impact crater was precision dated at 66,038 Mil BC with a 19,000 year tolerance, and does not correspond with the KT boundary. Currently the KT boundary date seems to have moved to 66 million years to make it fit in articles. The Chicxulub impact has caused its own extinction earlier but must have been overrun by the much bigger Shiva impact
The hypothesis by Sankar Chatterjee, a paleontologist at Texas Tech University in Lubbock claims it was multiple impacts with the Shiva impact that created the KT boundary event. This can be concluded from the K-T clay boundary layer in India that is one meter thick – the thickest in the world. It also fit the time the Indian plate started speeding up to a speed not associated with plate tectonics
The impact position and timeframe fit the spike of volcanism at the Deccan traps. However the problem for precision dating the Shiva crater arises due to the oil companies and the Indian government controlling the site where Shiva is located, and access is extremely limited (for some reason impact sites do not seem to be taken seriously by science or maybe politicians, because studies on impacts are rare. Many are unconfirmed but not scientifically looked at)
10,835-10,735 BC (Impact & Climate) – I think we can start the 6th major extinction around this time. We can also assume that it begins with an impact swarm at the onset of the Younger Dryas event. Lately too much evidence worldwide came to light that indicates a multi impact scenario. It is clear there were many short-term events over the last 12,000+ years that challenged life multiple times. There are also many opinions that differ about possible causes that is why I like to put supernovas in the spotlight as another possibility.

Supernovas:

Most major disturbances of earth's biosphere can be attributed to the explosion shock waves of supernovas. The duration of supernova debris stream flowing past Earth growing in intensity till around the middle, can last many years. Heating spikes at the end of glaciations periods correlates well with supernova shock and debris streams. We see it, then get the shockwave, after which the cosmic debris (particles) start building up causing heat. When they eventually die down it always leads to a balancing cooling period as the solar system returns to normal
The debris stream of Nova WZ Sagittae started in the 1965 to 1970 time region and seems to be at least part if not the main reason of our current climate warming episode with the solar system heating up (not only Earth)
Supernova impacts and the timing of megafauna extinctions and civilization collapses in the past 50,000 years also correlates with the times when the shock, debris streams and cooling down have impacted earth

The Sun:

We really need to incorporate the electrical universe theory. I do not have a problem with comet ice melting forming a tail, but when a comet is too far from the sun it can only be electrical discharges in plasma/magnetic-fields we see glowing
The CME’s and electrical discharges could however change if the sun throws the tantrum we can only theorise about. I think I saw one in the unedited 01/02 10 2011 comet that hits the sun and I’m still convinced that if the blowout was directed to Earth, we were in big trouble (KFC all around on the receiving side, but I do not see a week of warming. Yes, damage to the ozone layer will longer to recover – maybe this is how a Star gets over aggressive – the harder someone pinch me the higher I jump)
The Neat comet that came around the Sun in December 2002 – March 2003 was a monster and nearly as big as the sun and caused the "Halloween Events" of October/November 2003 that were not reflected by the normal sunspot numbers and behaviour (cycles). (Maybe Planet X fooled everyone and came early, causing some changes/damage in our plasma protection)

Sea Levels:

Data on sea levels show a trend of rising in bursts but currently seems normal in Durban, South Africa for the past 3,000-4,000 years with an average of ± 1.49 mm/yr. Extreme weather does cause damage that needs rehabilitation. Some continental plates around the world are most probably sinking where the measurements is going crazy.

Plate tectonics:

Plate movement is the biggest local contributor towards climate. It affects secondary influences like sea currents, wind directions and many more.

Conclusion:

Antarctica is not heading towards an ice free period as its dead centre on top of the South Pole and we know that the angle of the Sun is the most influential in climate cycles (Even Mercury got ice on its Northern Pole with the day side temperatures reaching 427 °C)
Antarctica is controlling Earth’s climate since millions of years ago when it started migrating to the South Pole accumulating ice. I also do not believe this is the first time Earth experienced this extremes climate fluctuations which are getting more extreme, because there were more severe ice ages before our time. (There must have been landmasses on a pole or both accumulating ice during heavy Ice ages)
Currently we are supposed to be in or close proximity of a glaciations period according to normal cycles. I cannot prove a supernova stream gave us extra time since the late 60’s but can’t find any other explanation that correlate with this time except “Rolling Thunder”. The problem is we are busy going into a natural quiet period of the Sun that I hope is just a mini cold period. If it combines with the supernova cooling period we are in trouble, but who knows, we do not seem to be at the right spot of the Milankovitch Cycles. But the big freeze and food shortages is coming (Welcome to the lockdown exercise, scientific infighting with lies and mayhem – time for survival mode)

4,404 Mil BC (Other) – The oldest dated zircon crystals of Hadean rocks enclosed in sandstone with evidence of liquid water in Western Australia were found, while others younger rocks during this Eon were found in Western Greenland and North-western Canada. Minerals were also found in rocks that point to the existence of plate tectonics as early as 4,000 million years ago
4,280 Mil BC (Other) – Water started condensing into liquid form
4,100-3,800 Mil BC (Multiple Impacts) – The Late Heavy Bombardment dated at 3,900 Mil BC on the Moon rocks collected by Apollo (An earlier date could have been “reset” by later impacts)

3,900 Mil BC (Atmosphere) – The atmosphere became mostly carbon dioxide, water vapor, methane and ammonia
3,900 -2,700 Mil BC (Other) – The existence of a hypothetical continent Ur/Vaalbara was proposed due to similarities between the Transvaal Basin craton in South Africa and the Hamersley Basin craton in Australia. This is scientifically not agreed upon as Earth was believed to hot and volcanic without plate tectonics for continents to form and therefore just the product of global processes forming cratons
(The problem with not believing in continents at this stage is the large meteorite impacts between 3,500 and 3,200 million years ago detectable in the Kaapvaal Barberton granite-greenstone terrain and Pilbara's eastern block. Also 2,900 million years ago the first record of glaciations in the Pongola region of the now Southern Africa was found, although the find is restricted to that area and may represent regional glaciations.)

1,800-1,600 Mil BC (Plate tectonics) – A general starting point for continents and how Earth looked. Slowly but surely the scientists are piecing together a picture of the breakups and formations. It is believed that a super continent “Columbia” formed during this period as Earth’s crust thickens and stabilize (Columbia, also known as Nuna and Hudsonland, was the reassembly of continental blocks either from Ur/Vaalbara (2,700 million years ago) or Kenorland (2,400 million years ago).

252.28 Mil BC (±11,000 years) (Volcanism, Atmosphere, Extinction & Climate) – The Triassic–Jurassic extinction was Earth's worst Mass extinction that eliminated 90% of ocean dwellers, and 70% of land plants and animals. It lasted less than 200,000 years and corresponds to a glaciations period. Sediment layers with an accuracy of 35,000 years in the Nanpanjiang basin in southern China prove this extinction period with a sea-water level decreased for around 80,000 years
Although the Siberian traps started 400,000 years before the main extinction it was a double extinction with the Siberian trap peeking 500,000 years after the glaciations period.
The Siberia Traps has the largest known deposited of lava and volcanic rocks on land and lasted for around 900,000 years with the main trap forming event less than 60,000 years at 500,000 years after the Permian-Triassic boundary extinction. With massif atmospheric changes and greenhouse gas releases (Oxygen (O2) levels dropped from 30% to 12% and Carbon dioxide (CO2) level was below 2000 ppm) and a global upward jump in temperature reach 50-60°C on land, and 40°C at the sea surface (this misery is far from solved, studies seem to prove the ocean extinction 1,5 million years after the boundary extinction)

[color=orange 232 Mil BC (Volcanism, Plate tectonics, Extinction, Atmosphere & Climate) – Durring the “Carnian Pluvial Episode” shock events there were four pulses of warming and climate perturbation, all within a million years that have led to repeated extinctions. The climates shuttled from dry to humid and back to dry again possibly due to eruptions in western Canada, represented today by the great Wrangellia basalts. The Carnian Pluvial Event was a regional climatic perturbation mostly visible in the western Tethys that could be related to the uplift of a new mountain range, the Cimmerian Orogen

That we know about lol .
Ok thing is we are not just some bird or dino . Humans will eat any thing if Every last mammal went extinct we would just eat reptilians . If they went extinct we would eat roaches lol .

There is only one or 2 gratned way to kill us off thous would be a 99 % extinction .
Heck humans adapated to even living in space there is no environment we could not find a way to live in .

yes, LIFE.....finds a way

always finds some way

Agreed, we are just a virus that adapts and spreads.

I really like the premise of the OP. Thanks for the information.

But so much text!

I think there are times when TMI applies. Give us the highlights, synopsis and analysis. Use sources for the rest.

I'm not complaining. If anything many OP's today are woefully lacking in "real" information. But I had a hard time reading through that long list.

Maybe it's just me and I need to go off in the corner just STFU...

Nah, we figured this out about 10 years ago here on ATS.

Some guy in China pokes a yellow blob with a stick and causes the end of the world.
