Termination Zero: Earth Predicament May Be Totally Unprecedented...

Don\'t be so relentlessly stupid.

The incipient temperature rise isn\'t unprecedented. We had a preview 55.5 millions years ago. Back then it took some 20,000 years for some 2,000 to 7,000 gigatons of extra carbon to get dumped in the atmosphere. We\'ve dumped about 650 gigatons of carbon into the atmosphere, so not yet as much, if quite a bit faster.

Back then it got some 5 to 8 degrees Celcius warmer and stayed warm over about 200,000 years. Our fairly remote ancestors didn\'t find it uninhabitable - they may have moved further away from the equator, but they clearly survived or we wouldn\'t be here.

Could it be that the rise of electric cars caused the accelerated methane growth after 2006?

See how dangerous drawing conclusions from statistics can be...

If we dump enough CO2 we might delay the next ice age. But I doubt
that would work. Some sort of geo-engineering might.

Those ancestors weren\'t human. If there was a higher form of human, they all died off and were survived by the dregs of their species to become the modern human race.

It\'s looking more and more like nature is the prime mover in this equation. Mankind\'s contribution is an additive noise, comparatively small, but enough to send the Earth\'s global dynamics into a new trajectory. Apparently there is quite a lot of gain from mankind\'s additive noise to the motion in the trajectory.

Doesn\'t look like an ice age on the horizon any time soon. Climatologists are trying to figure out what\'s happening right now, it will be quite some time before they can make any forecasts.

It was all about the transition from ice ages to interglacials which have been happening for the past 2.6 million years. The current episode is a transition to atmosdpheric C)2 levels which we haven\'t seen for about 20 million year, so this is a different \"rodeo\".

Back then it got some 5 to 8 degrees Celcius warmer and stayed warm over about 200,000 years. Our fairly remote ancestors didn\'t find it uninhabitable - they may have moved further away from the equator, but they clearly survived or we wouldn\'t be here.

In evolutionary terms the survivors are always the variants best adapted to their environment. Nothing that was around aback then for which fossils have survived had a big enough brain case to have been labelled hominid. let alone human

I don\'t have anything wrong. It\'s your reading comprehension that\'s lacking..

You did, in your subject line.

According to the Earth Science professor, per study of methane bubbles in ice cores:

\"Full terminations take several thousands of years to complete, but many include a creeping onset of warming, then a very abrupt phase of extremely rapid climate change that can take a century or less, followed by a longer, slower period during which the great ice caps finally melt.\"

As regards the latest ice age, presumably the Earth already went through its abrupt temperature rise phase some 10,000 years ago, a transition that lasts about a century, and up until modern times was in a very slow and lengthy temperature rise lasting 100,000 years ( who knows?) until the polar caps melt. What\'s unprecedented is this second abrupt temperature rise occurring now during what should be a very gradual rise. The abrupt temperature rise is only projected to occur based on the rapid rise in atmospheric methane happening now, it hasn\'t actually occurred yet, obviously.

The unprecedented part of the article is this:

\"Since 2006, the amount of heat-trapping methane in Earth\'s atmosphere has been rising fast and, unlike the rise in carbon dioxide (CO₂), methane\'s recent increase seems to be driven by biological emissions, not the burning of fossil fuels.\"

There\'s no \"seems\" to it. Physicists can actually pinpoint the geographic location of the methane emission by analyzing its molecular structure, which means they can determine with certainty it\'s due to natural biological process and not gas line leaks.

The whole point of the article is the Earth\'s been at this rodeo before..

The rodeo is the oscillatory transitioning. No one is fixated on CO2 levels except as regards how they affect the oscillation, and that is mainly through the Earth solar energy imbalance. Apparently the CO2 induced warming is triggering a positive feedback of methane emission in the natural course of events.

Back then it got some 5 to 8 degrees Celcius warmer and stayed warm over about 200,000 years. Our fairly remote ancestors didn\'t find it uninhabitable - they may have moved further away from the equator, but they clearly survived or we wouldn\'t be here.

That\'s a bunch of Stone Age era research from almost 20 years ago based on a bunch of conjecture. They had nowhere near the amount data and understanding available to modern researchers. Not going to waste time looking at it, because I know those reports are full of \"may\"s and \"could\"s.

\"Full terminations take several thousands of years to complete, but many include a creeping onset of warming, then a very abrupt phase of extremely rapid climate change that can take a century or less, followed by a longer, slower period during which the great ice caps finally melt.\"

As regards the latest ice age, presumably the Earth already went through its abrupt temperature rise phase some 10,000 years ago, a transition that lasts about a century, and up until modern times was in a very slow and lengthy temperature rise lasting 100,000 years ( who knows?) until the polar caps melt.

There\'s no \"seems\" to it. Physicists can actually pinpoint the geographic location of the methane emission by analyzing its molecular structure, which means they can determine with certainty it\'s due to natural biological process and not gas line leaks.

They don\'t analyse the \"biological structure\" of methane, which is really simple molecule, but it\'s C-14 isotope content, which tells you how long it has been i the ground, not where it came from - all methane seems to be of biological origin. If it comes from the thawing of frozen tundra it can have been laid down fairly recently - but doesn\'t have to have been. C-14 has a half life of 5700 years, but that doesn\'t get you geological time scales.

The whole point of the article is the Earth\'s been at this rodeo before.

It was all about the transition from ice ages to interglacials which have been happening for the past 2.6 million years. The current episode is a transition to atmospheric C)2 levels which we haven\'t seen for about 20 million year, so this is a different \"rodeo\".

The rodeo is the oscillatory transitioning. No one is fixated on CO2 levels except as regards how they affect the oscillation, and that is mainly through the Earth solar energy imbalance. Apparently the CO2 induced warming is triggering a positive feedback of methane emission in the natural course of events.

If we dump enough CO2 we might delay the next ice age. But I doubt
that would work. Some sort of geo-engineering might.

Doesn\'t look like an ice age on the horizon any time soon. Climatologists are trying to figure out what\'s happening right now, it will be quite some time before they can make any forecasts.
Not true,

Don\'t be so relentlessly stupid.

Try taking your advice yourself.

Telling you that you have got stuff wrong is as pointless as telling Flyguy the same thing, but pointing out errors isn\'t stupid.

I don\'t have anything wrong. It\'s your reading comprehension that\'s lacking.
That\'s Flyguy\'s opinion too.
The incipient temperature rise isn\'t unprecedented. We had a preview 55.5 millions years ago. Back then it took some 20,000 years for some 2,000 to 7,000 gigatons of extra carbon to get dumped in the atmosphere. We\'ve dumped about 650 gigatons of carbon into the atmosphere, so not yet as much, if quite a bit faster.

Who said it was unprecedented?

You did, in your subject line.

According to the Earth Science professor, per study of methane bubbles in ice cores:

\"Full terminations take several thousands of years to complete, but many include a creeping onset of warming, then a very abrupt phase of extremely rapid climate change that can take a century or less, followed by a longer, slower period during which the great ice caps finally melt.\"

As regards the latest ice age, presumably the Earth already went through its abrupt temperature rise phase some 10,000 years ago, a transition that lasts about a century, and up until modern times was in a very slow and lengthy temperature rise lasting 100,000 years ( who knows?) until the polar caps melt. What\'s unprecedented is this second abrupt temperature rise occurring now during what should be a very gradual rise. The abrupt temperature rise is only projected to occur based on the rapid rise in atmospheric methane happening now, it hasn\'t actually occurred yet, obviously.

The unprecedented part of the article is this:

\"Since 2006, the amount of heat-trapping methane in Earth\'s atmosphere has been rising fast and, unlike the rise in carbon dioxide (CO₂), methane\'s recent increase seems to be driven by biological emissions, not the burning of fossil fuels.\"

There\'s no \"seems\" to it. Physicists can actually pinpoint the geographic location of the methane emission by analyzing its molecular structure, which means they can determine with certainty it\'s due to natural biological process and not gas line leaks.
They don\'t analyse the \"biological structure\" of methane, which is really simple molecule, but it\'s C-14 isotope content, which tells you how long it has been i the ground, not where it came from - all methane seems to be of biological origin. If it comes from the thawing of frozen tundra it can have been laid down fairly recently - but doesn\'t have to have been. C-14 has a half life of 5700 years, but that doesn\'t get you geological time scales.

That is a misbelief and no longer true. There are other characteristics of the molecular structure which when analyzed can locate the source to a particular region, after that region has been assayed. They can also do the same with CO2. Everything becomes unique when it\'s looked at in fine enough detail.

The whole point of the article is the Earth\'s been at this rodeo before.

It was all about the transition from ice ages to interglacials which have been happening for the past 2.6 million years. The current episode is a transition to atmospheric C)2 levels which we haven\'t seen for about 20 million year, so this is a different \"rodeo\".

The rodeo is the oscillatory transitioning. No one is fixated on CO2 levels except as regards how they affect the oscillation, and that is mainly through the Earth solar energy imbalance. Apparently the CO2 induced warming is triggering a positive feedback of methane emission in the natural course of events.
And it has done it at the end of every interglacial for the past 2.6 million years. The extra CO2 we have injected into the atmosphere is warming up frozen tundra \\and other methane-ice clathrates that survived previous interglacials. We\'ve no idea how much of it there is

https://en.wikipedia.org/wiki/Methane_clathrate

Most researchers don\'t consider it to be likely that this will to make anthropogenic global warming run away, but there\'s always a market for hysterical alarmism.

That\'s just another example of your boring static thinking.

It seems the current sudden increase in temperature they\'re experiencing now is completely novel because it departs from the climate parallel record of slow and gradual temperature increase from every other post-glacial they know about. The only other variable is time. The anthropogenic contribution is being applied very quickly, almost an impulse on climatic scale, and that is what\'s causing all this weird and unprecedented behavior, despite in absolute terms the AGHG being a relatively small fraction of the totality of what\'s going on. The dynamics of it gives it more weight.

Back then it got some 5 to 8 degrees Celcius warmer and stayed warm over about 200,000 years. Our fairly remote ancestors didn\'t find it uninhabitable - they may have moved further away from the equator, but they clearly survived or we wouldn\'t be here.

Once somebody got enough data to have a good idea what was going on, and publish that, the literature does tend to go quiet.

\"May\"s and \"could\"s are a feature of that kind of paper. It\'s climate change denial propaganda that goes in for positive assertions - their aim is convince, rather than inform.

It was an accomplishment in its day but gobs of billions have been invested in space based Earth observatories since, In many cases the data has been a real eye opener. One example is NASA\'s OCO-Orbiting Carbon Observatory. A widely held belief prior was that the tropical rain forest jungles were the \'lungs of the Earth\'. Turns out they\'re net emitters, and the real CO2 sinks are the boreal forests ( which are burning down worldwide right now).
That rather ignores the phytoplankton soaking up CO2 in the southern ocean and sinking it to the seafloor in their carbonate skeletons. The oxygen released by their photosynthetic activities doesn\'t sink.

\"Phytoplankton act as Earth’s lungs and have produced about half of all oxygen on Earth.\"

Statement by a plankton nut. What\'s producing the other half?

Who said it was unprecedented?

You did, in your subject line.

The misbelief is all yours, and you don\'t know what you are talking about.
There are other characteristics of the molecular structure which when analyzed can locate the source to a particular region, after that region has been assayed. They can also do the same with CO2. Everything becomes unique when it\'s looked at in fine enough detail.

Care to name just one of them? Methane is just four hydrogen atoms symetrically - tetrahedrally - arranged around a central carbon atom. You do have three isotopes of hydrogen (though tritium doesn\'t last long enough to come into it) and three isotope of carbon, but that\'s it.

Don\'t waste time handing out links.

Handing out non-existent links to non-existent research is particularly time-consuming. You screwed up. Admit it.

Name just one.

The whole point of the article is the Earth\'s been at this rodeo before.

It was all about the transition from ice ages to interglacials which have been happening for the past 2.6 million years. The current episode is a transition to atmospheric C)2 levels which we haven\'t seen for about 20 million year, so this is a different \"rodeo\".

The rodeo is the oscillatory transitioning. No one is fixated on CO2 levels except as regards how they affect the oscillation, and that is mainly through the Earth solar energy imbalance. Apparently the CO2 induced warming is triggering a positive feedback of methane emission in the natural course of events.

And it has done it at the end of every interglacial for the past 2.6 million years. The extra CO2 we have injected into the atmosphere is warming up frozen tundra \\and other methane-ice clathrates that survived previous interglacials. We\'ve no idea how much of it there is

https://en.wikipedia.org/wiki/Methane_clathrate

Most researchers don\'t consider it to be likely that this will to make anthropogenic global warming run away, but there\'s always a market for hysterical alarmism.

That\'s just another example of your boring static thinking.

Boring, static and correct. You have actually misunderstood what was being said, to a degree that puts you in the Flyguy category.

You\'re thinking is wrong. And you\'re always accusing people of being confused or not understanding something, when you\'re own statements are so simpleminded and erroneous.

You may find it satisfying to think so, as Flyguy does. but you haven\'t been able to demonstrate it.

It seems the current sudden increase in temperature they\'re experiencing now is completely novel because it departs from the climate parallel record of slow and gradual temperature increase from every other post-glacial they know about. The only other variable is time. The anthropogenic contribution is being applied very quickly, almost an impulse on climatic scale, and that is what\'s causing all this weird and unprecedented behavior, despite in absolute terms the AGHG being a relatively small fraction of the totality of what\'s going on. The dynamics of it gives it more weight.

\"AGHG\"?
Anthropogenic...

The \"A\" was easy. Google came up with \"American Global Health Group\" which [robably wasn\'t what you had in mind.

This isn\'t \"post-glacial\" warming. It\'s us replaying the Paleocene-Eocene Thermal Maximum by injecting more CO2 into the atmosphere. The extra methane that the article calls \"unexpected\" is coming out of the Arctic permafrost. The arctic is warming up some three times faster than the planet as a whole and people have been monitoring the extra methane coming out of the thawing permafrost for at least a decade now.

You didn\'t even read the article, numbskull. Everything post-glacial is warming. The climate naturally undulates between glacier- furnace (tropical climate polls).

If that\'s what you read into the article, you are as far gone as Flyguy. The climate has been cycling between ice and ages and interglacials ) which aren\'t any kind of furnace. for the past 2.6 million years. When the contents aren\'t in their current positions the average temperature of the planet is a bit higher but still not \"furnace like\" and doesn\'t undulate (or at least not nearly as much).
