A key theory that attributes the climate evolution of the Earth to the breakdown of Himalayan rocks may not explain the cooling over the past 15 million years, according to a Rutgers-led study.

The study in the journal Nature Geoscience could shed more light on the causes of long-term climate change. It centers on the long-term cooling that occurred before the recent global warming tied to from humanity.

"The findings of our study, if substantiated, raise more questions than they answered," said senior author Yair Rosenthal, a distinguished professor in the Department of Marine and Coastal Sciences in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick. "If the cooling is not due to enhanced Himalayan rock weathering, then what processes have been overlooked?"

For decades, the leading hypothesis has been that the collision of the Indian and Asian continents and uplifting of the Himalayas brought fresh rocks to the Earth's surface, making them more vulnerable to weathering that captured and stored carbon dioxide—a key greenhouse gas. But that hypothesis remains unconfirmed.

Lead author Weimin Si, a former Rutgers doctoral student now at Brown University, and Rosenthal challenge the hypothesis and examined deep-sea sediments rich with .

Over millions of years, the weathering of rocks captured carbon dioxide and rivers carried it to the ocean as dissolved inorganic carbon, which is used by algae to build their calcium shells. When algae die, their skeletons fall on the seafloor and get buried, locking carbon from the atmosphere in deep-sea sediments.

If weathering increases, the accumulation of calcium carbonate in the deep sea should increase. But after studying dozens of deep-sea sediment cores through an international ocean drilling program, Si found that calcium carbonate in shells decreased significantly over 15 million years, which suggests that may not be responsible for the long-term cooling.

Meanwhile, the scientists—surprisingly—also found that algae called coccolithophores adapted to the carbon dioxide decline over 15 million years by reducing their production of calcium carbonate. This reduction apparently was not taken into account in previous studies.

Many scientists believe that ocean acidification from high levels will reduce the calcium carbonate in algae, especially in the near future. The data, however, suggest the opposite occurred over the 15 million years before the current global warming spell.

Rosenthal's lab is now trying to answer these questions by studying the evolution of and other elements in the ocean.

Another unfortunate consequence of the mindless obsession with the still unproven theory that carbon dioxide is the primary driver of atmospheric warming and cooling. Climate science is in desperate need of another Galileo to refocus on the scientific method rather than what has become a global New Age cult.

I didn't see anything about radiative forcing in that study.

CO2 is NOT a greenhouse gas, despite what the AGW cultists insist. The reason (that no one seems to have realised) is that CO2 is recycled amongst Terran life forms continuously. It isn't a gas that can be seqeustered for very long unless it is sequestered in the tissues of a life form that is either alive or, like a tree that has been cut down, can remain within the tree even if it has become a piece of furniture.
But CO2 has a purpose, and that purpose is to FEED plants and trees (Carbon) and then the plant gives up the Oxygen2 back into the atmosphere where it again gets recycled by animals that breathe the Oxygen and exhale CO2. This is the cycle of life.

Sep 24, 2019
The ACTUAL GreenHouse Gas is METHANE. CH4 is a very volatile and dangerous gas, which is not spoken of very often as a GHG by AGW cultists because (or so it seems), it is their intention to rid the Earth of CO2 as though it is something as volatile and dangerous as Methane.
CO2 cannot explode; but Methane does. It is the 4 atoms of H in Methane that causes it to explode.
Plants and trees NEED CO2 to live, and humans and animals need the O that plants give off. This is a wonderful symbiotic relationship that humans/animals and plants have with each other.

Sep 24, 2019
This article from Science Daily attempts to prove the AGW myth but fails miserably, simply because the observations already prove that Methane is also to blame for past warming of the oceans where the source of GHG are hydrothermal vents and undersea volcanos. Present-day AGW is merely an afterthought and the works of Nature regarding Carbon in the oceans is mentioned more often.

We need to very careful these days. There's massive amounts H2O near all sites of major human population. It is a very dangerous molecule as it has 2 H atoms and O atom, everything you need for a big explosion. Methane lacks the oxygen so it isn't as bad as H2O!

That's because the sun's output doesn't correlate with the changes in climate they are studying (as it doesn't also for current warming).

CO2 is NOT a greenhouse gas
Despite what the AGW cultists insist
The reason
That no one seems to have realised
Is that CO2
Is recycled
Amongst Terrain life forms continuously
It isn't a gas
That can be sequestered
For very long
Unless it is sequestered
In the tissues
Of a life form
That is either alive
Or
Like a tree that has been cut down
Can remain within the tree
Even if it has become a piece of furniture
But CO2 has a purpose
And that purpose
Is to FEED plants
And trees (Carbon)
And then the plant
Gives up the Oxygen2
Back into the atmosphere
Where it again gets recycled
By animals that breathe
The Oxygen
And exhale CO2
This is the cycle of life

Sep 24, 2019
Well, hmmmm. Not sure I'm buying this, but the hypothesis that the new rock from the upthrust of the Himalayas was responsible for the cooling due to carbon uptake is looking a little wobbly. I'll be interested what they propose as an alternative (since none was proposed in either the article or the paper, apparently).

Free speech is a UNHRD right, but so is freedom from hate speech, so it has to be balanced in most of the world. Let the US keep its non-UNHRD free speech (and free weapons!) extremist laws and regulations, until such time we know from observation one or the other method is better.

In any case, science and its discussion should not be fact free but concern the science and admit the facts. Trolling and denial is for open social discussions, and if Phys.org wants to be moderated like the Conversation, kudos to them.

I don't know about here specifically. But IIRC it has been publicized that the politicized US climate debate and the Russian troll plants are both results of organized efforts, from fossil fuel industry interests respectively a corrupt oligarch society.

Speaking of which, Trump has mastered the Russian technique. When Greta Thunberg saw him and gave him the evil eye alongside her emotional speech where she claimed the world leaders stole her childhood, Trump of course gave the expected confusing answer along the lines of 'what a happy child'. All in order to be reelected scum.

Agreed! They do make a good point and their data is massive, though it is less constrained since it is just a (fossil) biology proxy for the erosion and greenhouse gas circulation.

The mechanism that keeps us in a deep freeze, modulo the dangerous man made rapid global warming recently, is the south circumpolar circulation I believe [ https://en.wikipe..._Current ]. So maybe that got really going in the last 15 Myrs. "The isolation of Antarctica by the current is credited by many researchers with causing the glaciation of Antarctica and global cooling in the Eocene epoch."

C.f. https://www.youtu...hVJNnoZ4 .

Sep 24, 2019
The data, however, suggest the opposite occurred over the 15 million years before the current global warming spell

Opposite of the guesswork, yet the AGWites are focusing in on conspiracy theories. Typical lazy misplaced thinking.

Wow. You are one of the very few from the other side that I credited with intelligence. But, alas, such is the power of Cults, to produce the idiotic.
If the south circumpolar circulation is responsible for the glaciation of Antarctica. Then science dictates, it had to remove an incredible amount of energy from the billions of tons of water that it turned into ice. So, how does all that heat keep the rest of the planet in a deep freeze?
I hope you are not one of those, who leaves their refrigerator door open, in order to cool their home.

Typical denier comments here, spouting off about the carbon cycle that they don't understand or don't want to understand.
All forms of life on Earth are components of the natural active (fast) carbon cycle - and Fossil Fuels are not.
And that is a critical difference.

The components of the natural active carbon cycle are-
the atmosphere, oceans, top soils and all living things.
All the members of the natural carbon cycle give and take carbon.

Not true with fossil fuel emissions. They are not part of the active natural carbon cycle, and only give and don't take any back.
ALL of the carbon from burning fossil fuels is IN ADDITION to the normal amount that naturally moves through the carbon cycle.

Fossil fuels are carbon that nature sequestered away in the Earth over 10s of millions and 100s of millions of years, locking it out of the carbon cycle.

Humans are now putting all that sequestered carbon into the
carbon cycle in a few centuries - a nanosecond in geological
time scales

The Carbon Cycle

"Without human interference, the carbon in fossil fuels would leak slowly into the atmosphere through volcanic activity over millions of years in the slow carbon cycle. By burning coal, oil, and natural gas, we accelerate the process, releasing vast amounts of carbon (carbon that took millions of years to accumulate) into the atmosphere every year. By doing so, we move the carbon from the slow cycle to the fast cycle. In 2009, humans released about 8.4 billion tons of carbon into the atmosphere by burning fossil fuel."

The less information given in an article the more the misinformation given in the comments.
Climate change is not in dispute any more.
What is going on is more a religion thing, folks that are afraid of what climate change means pretend it is not real.
Pretend is the catchword, they KNOW it is going on as climate change is not rationally deniable. So it is irrationally denied.
The more fearful the person commenting the more vociferous the denial. I see this in under seven year old children as a regular feature of adolescence. Adults doing this are to be pitied rather than hated.

Antigoricle is a cult member
Since deniers believe hundreds of lies and myths about climate science, without any skepticism whatsoever, it's comical that they call AGW a cult. The assumption is that AGW is new science started by Al Gore, blah blah blah. In reality, it's over 150 years of research and tens of thousands of peer reviewed studies that have led to an overwhelming preponderance of EVIDENCE and a consensus.

Between 1991-2012 there were 13,950 peer reviewed research papers published.
24 of them reject AGW.
Of the 33,690 scientists who contributed to the 13,950 papers, only 34 reject AGW - That's 1/10 of 1%
-----
In the one year + from November 12, 2012 through December 31, 2013, -
there were 2,225 peer reviewed papers published by 9,136 contributing scientists.
Only ONE of those 9,136 rejects AGW - That's just over 1/100 of 1%

Exxon's own scientists told them AGW is real, caused by burning fossil fuels, FORTY YEARS AGO.
Then Exxon spent the last thirty years funding the denialist PR campaign of disinformation that people like Antigoracle mindlessly spew out.
The projections that Exxon scientists made in 1982, of CO2 levels and global temperature, were spot on, with current CO2 levels and global temperature rise. You can see a graph of their projections here.
---
"As far back as 1982 – 37 years ago – scientists working for oil and gas giant Exxon expertly predicted the shape of climate change to come.
With chilling, unnerving prescience, they foretold the very future of human-made global warming and plotted its calculable trajectory. Then, they buried it.
This is not an allegation. It's a documented fact: look at the graph they made. Marvel at how foresightful they were:"

"Is methane emission from cattle natural?"

Yes. However, when all the land usage issues adding to human caused CO2 emissions are combined with the unprecedented rise in CO2 from burning fossil fuels we have a problem.
CO2 has likely never increased this fast naturally.
We are increasing atmospheric CO2 100 times faster than the fastest that nature has done in At Least the last 450,000 years.
Humans increased CO2 by over 80ppm in 58 years
Humans increased CO2 by 130ppm in 138 years
------
Nature caused CO2 increases over the last 450,000 years, from ice core data

80ppm increase -- took 50,000 years
110ppm increase -- 25,000 years
120ppm increase --- 20,000 years
60ppm increase --- 20,000 years
90ppm increase --- 15,000 years
100ppm increase --- 24,800 years

The numbers for 800,000 years would be similar, based on a graph of ice core data going back that far.

Frflyer, your postulate

"Without human interference

Would leak slowly
Into the atmosphere
Through volcanic activity"

Over the millions of years
These plants have reduced this CO2 to its present level of 0.04%
Over these millions of years
These plants have not been able to prevent this steady decline

Based on your postulate frflyer, that the naturally sequestered CO2 is slowly leaking out
This CO2 should be increasing not reducing

p.s. frflyer, this is obviously before the introduction of the burning of fosil fuel on an industrial scale

Threatening Ukraine with denial of aid to get political dirt on Joe Biden was that straw. Screw the transcripts; let's see the whistleblower complaint first. In toto. Unredacted. Then let's hear from the whistleblower so we can see if they modified or redacted the complaint, in public testimony before House and Senate committees. After that we can compare it with the "transcripts" this criminal "president" presents. Better be good. Better be right.

Chew on this a while, @granny, and see what you come up with (and I mean in the sense of a cat horking up a hairball):

Here's an example: velocity can't kill you. But acceleration can; a constant acceleration can hold you until you starve and your internal organs fail because they can't move necessary substances into your blood. But that's slow; if you measure the rate of change of acceleration, that's called "jerk," and a high jerk can break all your bones and rupture all your cells, and then you are dead very quickly.

We are experiencing a jerk in climate. See how that works?

It seems that the terminology is all wrong. I would much prefer the term, "WEATHER CHANGE", such as, 'the weather is changing - it's getting too cold to wear shorts and a tee shirt'.

For one thing, if you live in Wisconsin or Montana in the US, it gets very cold with a lot of snow and ice in winter. Living under those weather conditions, you are not experiencing the hot, dry heat of the Saharan desert because that is the weather THERE, not the weather HERE. So, it is stupefyingly ridiculous to call it climate, unless it was the exact same weather EVERYWHERE.

For another thing, the weather is ALWAYS CHANGING. It's sunny one day, raining and cloudy the next; it could be cloudy and raining for a week, then suddenly the rain stops and it's sunny again.
Those changes are certainly NOT climate, it is WEATHER.

What I want to know is when all the AGWs are going to stop driving their cars & heating your homes with natural gas?

All the AGWs commenting here far outnumber the Deniers, and AGWs according to you are the majority of the population. If AGWs are the majority groupthink in the 21st century, then the many billions of you could just stop driving your cars & heating yur homes and VOILA, problem more than 50% fixed.

But, NONE of you AGWs have gotten rid of your cars or the natural gas furnaces in your houses, right torbjorn_b_g_larsson? What have YOU given up to be an example to the DENIERS? Potato chips?

Today, I have a message for those open-border activists who cloak themselves in the rhetoric of 'social justice,'" Trump said. "Your policies are not just, your policies are cruel and evil."

"You are empowering criminal organizations that prey on innocent men, women, and children. You put your own false sense of virtue before the lives and well-being of countless innocent people. When you undermine border security you are undermining human rights and human dignity."
"America knows that while anyone can make war, only the most courageous can seek peace," he said. "America is ready to embrace friendship to all who genuinely seek peace and respect
says snoosebaum

Trump is, indeed, a superb leader of the free world. He LOVES his country and the American citizens. He is also a friend to PM Boris Johnson and other free world leaders. I dread to think what will happen to the US if any one of those Democrat Party candidates is elected POTUS in 2020. Socialism will happen.

Good to see you, Benni. Hope you are well.
Are you kidding? Torbjorn give up his creature comforts for the sake of the AGW cult which he pretends to be part of? E cars are too unreliable and the batteries are still having to be charged from coal or gas--powered electric companies. i.e. the grid. I think that TgbLarsson is a fake, but don't tell him that I said so.

No, by far the most plentiful greenhouse gas causing 90% of the greenhouse effect on Earth is WATER.

It is difficult to find an evidence that proves ocean acidification as an irreversible process. The new findings in this paper have opened the debate if reverse processes occurred in the past what caused them.

Is Himalayan weathering one of such processes? The process of weathering gives specific clues to the prevalent environmental conditions.

The comments by denialists here get kookier and kookier. Why doesn't PhysOrg adopt the same policy as " The Conversation ". It's about time these wackos stopped clogging up every climate article comments section.
says mancush

But then there would be NO conversation at all if all you had talking in these pysorg phorums are a big bunch of "YES-MEN" who offered nothing to the discussion but, "yes, I agree with you. You are so right and I have nothing against anything that you say. Please tell us more so that we can agree with you again."

LMAO


ROFLMAO We literally have a bunch of denier and oil funded monkeys who preaches the overwhelming evidence for Human Induced Climate Change is not real, but all we hear to counter the monstrous amount of evidence for Human Induced Climate Change from the Deniers everyday is thumb sucked opinions, discussed and coordinated beforehand in a huddle up in their propaganda tree with their fellow sockpuppets,then posted on here Hilarious ;)

Old loser C lost it again. No dummy, water vapor does not control the Earth's temperature, but is instead controlled by the temperature. The greenhouse effect that has maintained the Earth's temperature at a level warm enough for human civilization to develop over the past several millennia is controlled by non-condensable gases, mainly carbon dioxide, CO2, with smaller contributions from methane, CH4, nitrous oxide, N2O, and ozone, O3. Since the middle of the 20th century, small amounts of man-made gases, mostly chlorine- and fluorine-containing solvents and refrigerants, have been added to the mix.

dumb argument, because of Oil, Oil is the dominant force of propelling vehicles globally, start to bring in more green technology and bring down prices, the world will adapt to it. But asking this question while people are literally forced to buy products monopolized by the fossil fuel industry because they have suppressed green technology for so long, is a joke ! Once people can afford green tech they will buy it ! !

Interesting - What a tangled web we weave

Over millions of years
The weathering of rocks
Captured carbon dioxide
And rivers carried it to the ocean
As dissolved inorganic carbon
Which is used by algae
To build their calcium carbonate shells
When algae die
Their skeletons fall on the seafloor and get buried
Locking carbon from the atmosphere in deep-sea sediments

Naturally occurring carbon gases
Trapped in reservoirs
Atop the seafloor
Escaped to superheat the planet in prehistory.
Scientists say events that began on the ocean bottom
Thousands of years ago
So disrupted the Earth's atmosphere
That it melted away the ice age
Those new findings
Challenge a long-standing paradigm
That ocean water alone
Regulated carbon dioxide

Fore this web is a web we can't escape - It's called Planet Earth

Making even a bigger clown out of his denialism and his goony followers.
Antigoricle is a cult member of
Since deniers believe hundreds of lies and myths about climate science, without any skepticism whatsoever, it's comical that they call AGW a cult. The assumption is that AGW is new science started by Al Gore, blah blah blah. In reality, it's over 150 years of research and tens of thousands of peer reviewed studies that have led to an overwhelming preponderance of EVIDENCE and a consensus.

Many of us do reduce driving and our fossil fuel usage every way we can. That you people do not may cost you later. What if we added carbon tax to your giant SUVs?

Sep 25, 2019
Concerning climate, none of the choices you make in your private life really matter if you have even one child.

I'm bad at making choices based on morality but money is a good way to guide me. Please, bring carbon taxes everywhere.

Thanks Da Schneib; For reminding us all, who in charge of our Solar Climate

Our Eight Hundred Thousand Mile Solar Ball of Fusion
Milutin Milanković
In the 1920s,
Hypothesized
Variations in eccentricity
Axial tilt
And precession of the Earth's orbit
Results in cyclical variation in the solar radiation reaching the Earth

There is another factor to include since 2005 our ball of fusion has had a very blank face
Going long periods without Sunspot
As normally with binoculars and card
You see a mass of equatorial Sunspots
The last time the Sun lost its Spots
The Thames froze and famine raged over Europe

When you put these cycles
Weathering rocks
Shells on the sea bed six miles down
Plus
This gradual
Year in year out
Gradual drop in temperature
This prognosis does not look good
For the last time our Sun lost its spots
The earth froze for a hundred years

Just think, Da Schneib
The Thames still frozen in summer lasting a hundred years
As it was in a recent spotless period

Our Solar Sun

The Earth's rotation around its axis, and revolution around the Sun

The Earth's orbit varies between nearly circular and elliptical
Its eccentricity varies
When the orbit is more elongated
There is more variation in the distance between the Earth and the Sun
And in the amount of solar radiation
At different times in the year
In addition
The rotational tilt of the Earth
Its obliquity
Changes slightly
A greater tilt makes the seasons more extreme
The direction in the fixed stars pointed to by the Earth's axis
Changes
Axial precession
While the Earth's elliptical orbit around the Sun rotates
Apsidal precession
The combined effect
Is that proximity to the Sun
Occurs during different astronomical seasons

Milankovitch studied these changes in these movements of the Earth
Which alter
The amount
And location
Of solar radiation reaching Earth

Granville your point is sometimes hard to understand as you cannot form proper sentences but if I'm correct you are pointing to a fact that the Sun's cycles control the Earth's climate?

Why is it then so that we are living a solar minimum yet we are reaching record temperatures?

Granville your point is sometimes hard to understand as you cannot form proper sentences but if I'm correct you are pointing to a fact that the Sun's cycles control the Earth's climate?

Why is it then so that we are living a solar minimum yet we are reaching record temperatures?

That when we are closest to our Sun
It is winter in these British Isles
The cold does not set in till months after this winter solstice

Over these hundreds of years
When the sun is cooling down
As cooling in solar sunly terms only has to be 1 degree centigrade
It takes a long while before our heat sink
This heat sink of these crusts and oceans
To radiate their heat into the vacuum of space
For as this solar drop in temperature of spotless sunspots takes hold
It takes, 100s, 1000s 1,000,000s of years of deep freeze
Till that day
When our sun finds its sunspots once more
When our sun raises its temperature by one degree centigrade
Slowly warming our earth once again!

We have to bask in these heat waves
Bask in these extremes of this earthly weather

In this vain hope
That our sun
Can again regain is equatorial sunspots

That these extremes of weather
As this planet cools
Do not become these extremes of this coming Ice Age

For we can cope with these heat waves
We can copes with these glorious summers
We do not want these Siberian winters to be our summer heat waves

The middle of February 2018, was snowing, when East Anglia basked in desert summer temperatures
Whereas
The middle of February 2019 was 20C, when this East Anglia Summer was a washout
We are already basking in snowless winters, of summer temperatures
