How do we Know Human are Causing Climate Change?

[abu afak]

Exactly, as I had already stated - the Dino's went Extinct due to Global Warming, caused by Excessive Farting and Shitting, at average at a 100 times more then a Human.
And latest scientific hypothetical studies have revealed (books not published yet) that around 25 billion Dino's populated the Earth, just before they went extinct.

Um, No.
There must be STUPID CONTEST Going on here.
Unbelievably well known is that the Dinosaur's got wiped out by the Chicxulub Meteor Strike app 70 Million yrs ago.
It blasted and incinerated almost everything in a few days, followed by years of super-cold earth due to particulate matter blocking the sunlight.
NOT "Global Warming," "farting and shitting" you Breathtaking Idiot.
Impossibly STUPID!
3rd grade? 4th?
WTF!

Of course, even before the strike the earth WAS warm enough that it had No Ice Poles, and ergo that heat would Raise Sea Level 230' for US well before we got to that level of heat.
Ooops.

And we have 7-8 Billion Humans and probably just as many farm animals, Cows, Pigs, Dogs, Horses, etc, not counting wild animals.
NOT all Dinos were Giants/Large either, only the Famous ones. Many were small. What an amateur misimpression.

How do you think we'd do?

Writing in bold letters doesn't help your hypothesis.
That meteor went down 3769 years after the big Dino's had all gone extinct (Books not published yet) Then came the smaller Dino's - you know less/smaller farts and shits.

Everyone knows that, you ever went to school? or homeschooling? I guess the latter, brought up by Hippies in a VW Bulli.

I'm curious how 3,769 year span was measured from 66 million years ago given that the potassium-argon dating used on the K-T impact had an accuracy of +/- 11,000 years.

Yes I noticed that Idiotic Precision despite 70 Million Years!!
Maybe 30,000-50,000 years at best.
3,000-4000 Unbelievable.

But '3769' years after THEE LAST dinosaur died.
WTF!
No Dino made it 4500, 3900, or even 3800, but Exactly '3769' years.
An Impossibly precise and Gigantically Idiotic and Lying claim.
Only someone incredibly Stupid (or in a cult) would make/Try it.
`
Kruska also Whiffed on me pointing out there would be No Ice poles, and Sea level would be 230' higher at even lower temps than that period.

You do know that goes against the scientific theory that the dino's went extinct due to the meteor that crashed into the Earth?

 

[Kruska]

You do know that goes against the scientific theory that the dino's went extinct due to the meteor that crashed into the Earth?

How should anyone know that, if the Dino's had already gone extinct BEFORE the meteor crashed? as such as you correctly stated its a "Theory".
And Global warming caused solely or in vast majority by CO2, due to human activity, is a Theory as well.
And that Aliens started seeding the planet in order to develop human live - is a Theory as well, but I admit. that it is an entertaining Theory.

Because CO2 stays in the atmosphere for anywhere from 300 to 1,000 years, (That is a hell of a broad estimated guess - and shows that scientists factually are simply guessing), the levels aren't going to come down quickly no matter how much humanity cuts production. And added CO2 emissions due to natural occurrences are going to increase temperature.

Natural CO2 comes from e.g. out-gassing of the oceans, decomposing plants, wildfires, volcanoes. Plus Human activity %? and the total CO2 is around 0.04% of earth atmosphere.

Despite the worlds industrial/economic lock-down for almost 3 years (especially in China) with additional far fewer fossil burning vehicles being moved around in that period, and additionally millions of e-vehicles being bought, registered and having replaced fossil burning vehicles in China (I live and work in China) and with less then 40% of the usual air-traffic, Scientists claim that emissions in China were 7% higher in 2021 when compared to 2019.

Off course the global warming, (caused by human activity CO2 community) already has an answer - China produced less, worked less, drove less, flew less, millions more e-vehicles, replacing fossil vehicles, but China's jump was mostly from burning coal and natural gas and was part of a massive economic stimulus to recover from the lock-down.

Ahmm.. massive economic stimulus in China from 2019 - 2022? via decreased industrial production and thus a decreased sale and movement of goods?
It just shows that these CO2 stats and scientists propagating global warming caused solely or in vast majority via human actions producing CO2 - simply doesn't hold.

I was told the other day that if you took an eyedropper of oil and dropped one drop in the ocean, the oil will spread the entire ocean. Just some information on the people you're talking with . hahahahahahahaahahaahahaha. BTW, all their talking points are the same. No variance at all.

That has been published. See: AR6 Climate Change 2021: The Physical Science Basis — IPCC or AR6 Synthesis Report: Climate Change 2023 — IPCC

Dinosaur biodiversity declined well before the asteroid impact, influenced by ecological and environmental pressures - Nature Communications

Dinosaurs are thought to have been driven extinct by an asteroid impact 66 million years ago. Here, Condamine et al. show that six major dinosaur families were already in decline in the preceding 10 million years, possibly due to global cooling and competition among herbivores.

www.nature.com

We first find strong evidence that dinosaurs began to decline well before the K/Pg extinction due to both a marked increase of extinction from the late Campanian onwards and a decrease in their ability to replace extinct species. Our results also reveal that long-term environmental changes likely made dinosaurs particularly prone to extinction because of a combination of global climate cooling, a drop in diversity of herbivorous dinosaurs, and age-dependent extinction that impacted dinosaur extinction in the Maastrichtian.

Don't tell crick. IPCC said otherwise, and they are the fking gospel of the warmers.

I don't believe the IPCC said any such thing and I haven't the faintest idea why you think it would matter to me or anyone else. No one is arguing that only humans can cause climate change.

The Green New Deal Is a Dead Man's Hand

Fewer auto-emissions enabled the cronyvirus to survive and spread. Otherwise, it would have fizzled out, just like many others have after driving became widespread. The Greenies are not only anti-growth, they are also anti-health.

If there are any independent minds left, all the facts you present could be looked at as evidence that "pollution," (a dishonest term taken from a primitive superstition) is antiseptic.

How do we Know Human are Causing Climate Change?​

The air is clean at one point. Humans develop things that oust shit into the air.

I remember Acid Rain. I remember the denialists. I remember how it was dealt with.

To believe humans do not contribute -- contribute to the climate changing, is wilful ignorance on a grand scale. I'm unaware of credible people claiming humans are The cause alone.

 

[abu afak]

Climate Myth...​

Human CO2 is a tiny % of CO2 emissions
“The oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atpmosphere contains 720 billion tons of CO2 and humans contribute only 6 GT additional load on this balance. The oceans, land and atpmosphere exchange CO2 continuously so the additional load by humans is incredibly small. A small shift in the balance between oceans and air would cause a CO2 much more severe rise than anything we could produce.”


Before the industrial revolution, the CO2 content in the air remained quite steady for thousands of years. Natural CO2 is not static, however. It is generated by natural processes, and absorbed by others.

As you can see in Figure 1, natural land and ocean carbon remains roughly in balance and have done so for a long time – and we know this because we can measure historic levels of CO2 in the atmosphere both directly (in ice cores) and indirectly (through proxies).

Figure 1: Global carbon cycle. Numbers represent flux of carbon dioxide in gigatons (Source: Figure 7.3, IPCC AR4).

But consider what happens when more CO2 is released from outside of the natural carbon cycle – by burning fossil fuels. Although our output of 29 gigatons of CO2 is tiny compared to the 750 gigatons moving through the carbon cycle each year, it adds up because the land and ocean cannot absorb all of the extra CO2. About 60% of this additional CO2 is absorbed. The rest remains in the atmosphere, and as a consequence, atmospheric CO2 is at its highest level in 15 to 20 million years (Tripati et al. 2009). (A natural change of 100ppm normally takes 5,000 to 20,000 years. The recent increase of 100ppm has taken just 120 years). [Paragraph updated July 2022, to correct information on % of additional CO2 that is absorbed.]

Human CO2 emissions upset the natural balance of the carbon cycle. Man-made CO2 in the atmosphere has increased by a third since the pre-industrial era, creating an artificial forcing of global temperatures which is warming the planet. While fossil-fuel derived CO2 is a very small component of the global carbon cycle, the extra CO2 is cumulative because the natural carbon exchange cannot absorb all the additional CO2.

The level of atmospheric CO2 is building up, the additional CO2 is being produced by burning fossil fuels, and that build up is accelerating.

[Crick]

How should anyone know that, if the Dino's had already gone extinct BEFORE the meteor crashed?

They did not. They had issues, primarily from two million years of volcanic eruptions at the massive Deccan Traps, but all animals larger than 25 kg were made extinct by the Chicxulub impact 66.0 million years ago.

as such as you correctly stated its a "Theory".

A theory is not a guess. And the KT impact extinction theory is widely accepted by paleontologists.

And Global warming caused solely or in vast majority by CO2, due to human activity, is a Theory as well.

Yes, a very widely accepted one.

And that Aliens started seeding the planet in order to develop human live - is a Theory as well, but I admit. that it is an entertaining Theory.

There is no evidence of aliens seeding the planet. This is simple speculation, not even a hypothesis and certainly not a widely accepted theory.

Because CO2 stays in the atmosphere for anywhere from 300 to 1,000 years, (That is a hell of a broad estimated guess - and shows that scientists factually are simply guessing)

It is not a guess. It is given as a range because CO2 undergoes constant exchange with the oceans - going in to and out of solution. So, an individual CO2 molecule might only reside in the atmosphere for days, the level of CO2 in the atmosphere, however, does not change for centuries.

the levels aren't going to come down quickly no matter how much humanity cuts production.

That's correct, though several methods of removing CO2 from the atmosphere have been explored and some are even in progress. The restoration of deforested areas is effective in this regard.

And added CO2 emissions due to natural occurrences are going to increase temperature.

The Earth's CO2 levels had remained within 280 - 300 ppm for more than the last million years prior to the Industrial Revolultion. Natural sources are not an issue.

Natural CO2 comes from e.g. out-gassing of the oceans, decomposing plants, wildfires, volcanoes.

All atmospheric gasses have been in dynamic solutions in our oceans since we had both atmosphere and oceans. Current marine levels are elevated because it it elevated in the atmosphere above it. The amount of CO2 in solution is inversely dependent on temperature and directly dependent on its partial pressure in the atmosphere.

Plus Human activity %? and the total CO2 is around 0.04% of earth atmosphere.

Yes, 420 ppm, roughly 50% higher than it has been for over a million years..

Despite the worlds industrial/economic lock-down for almost 3 years (especially in China) with additional far fewer fossil burning vehicles being moved around in that period, and additionally millions of e-vehicles being bought, registered and having replaced fossil burning vehicles in China (I live and work in China) and with less then 40% of the usual air-traffic, Scientists claim that emissions in China were 7% higher in 2021 when compared to 2019.

The global reduction in CO2 emissions during the pandemic came to a 5-7% drop in annual emissions.

Off (sic) course the global warming, (caused by human activity CO2 community) already has an answer - China produced less, worked less, drove less, flew less, millions more e-vehicles, replacing fossil vehicles, but China's jump was mostly from burning coal and natural gas and was part of a massive economic stimulus to recover from the lock-down.

Remember that 300 - 1,000 year lifetime for CO2 in the atmosphere? The amount of CO2 already in our air is far, far larger than the annual emissions. Even if all CO2 emissions had stopped during the pandemic, the change in atmospheric level would have been minute. There was no massive economic stimulus DURING the pandemic so I would suggest either you've misunderstood someone, listened to the wrong source or have just made that up.

Ahmm.. massive economic stimulus in China from 2019 - 2022? via decreased industrial production and thus a decreased sale and movement of goods?
It just shows that these CO2 stats and scientists propagating global warming caused solely or in vast majority via human actions producing CO2 - simply doesn't hold.

That has nothing whatsoever to do with AGW. Global warming is taking place and its primary cause is the greenhouse effect acting on human greenhouse gas emissions.

 

[Kruska]

They did not. They had issues, primarily from two million years of volcanic eruptions at the massive Deccan Traps, but all animals larger than 25 kg were made extinct by the Chicxulub impact 66.0 million years ago.

How do you know that this meteor made his crash landing 66 million years ago?

There is no evidence of aliens seeding the planet. This is simple speculation, not even a hypothesis and certainly not a widely accepted theory.

Just because evidence hasn't been found yet - doesn't exclude a probability aka theory. - See global warming caused by human industrial activity=pure theory.

It is not a guess. It is given as a range because CO2 undergoes constant exchange with the oceans - going in to and out of solution. So, an individual CO2 molecule might only reside in the atmosphere for days, the level of CO2 in the atmosphere, however, does not change for centuries.

It is a guess because no one knows the exact ratios regarding constant exchanges, nor the exact volumes involved.

That's correct, though several methods of removing CO2 from the atmosphere have been explored and some are even in progress. The restoration of deforested areas is effective in this regard.

That is the only sense making argument so far - simply due to previous deforestation and in parallel an increase in human population. Absolutely nothing to do with industrial or vehicles emissions.

The Earth's CO2 levels had remained within 280 - 300 ppm for more than the last million years prior to the Industrial Revolultion. Natural sources are not an issue.

Those 280-300ppm are entirely due to natural sources - or did cars and factories exist since a million years?
The main problem with these ice core evaluations is the average ppm that is concluded form those examinations - is ignoring peaks and valleys.
The other question would be as to how representative are these Ice-core values in regards to the rest of the planet? Just because an ice-core sample would shown an average temperature on Antarctica as e.g. 15 Celsius - doesn't exclude the fact that somewhere else the average temperature would be 35 Celsius.

All atmospheric gasses have been in dynamic solutions in our oceans since we had both atmosphere and oceans. Current marine levels are elevated because it it elevated in the atmosphere above it. The amount of CO2 in solution is inversely dependent on temperature and directly dependent on its partial pressure in the atmosphere.

There are no figures known to me that could/would state figures in regards to CO2 emission form e.g. Oceans - increasing or decreasing due to tectonic changes in elevation or subsiding of the Ocean floors - thus having a decisive impact on the oceans volume in the past 1 million years. Neither are there figures available in regards to the impact of e.g. Volcanic activities in those 1 million years. All you guys have is an average value of 280-300ppm.

Yes, 420 ppm, roughly 50% higher than it has been for over a million years..

Okay - but again there is no proof as to what caused this 100-120ppm increase. Only the theory of man made emissions. So what caused an increase to 450ppm e.g. 670000 years ago? industry? cars?

The global reduction in CO2 emissions during the pandemic came to a 5-7% drop in annual emissions.

India +3.5%, China +7% - According to Scientific researches conducted by GW theorists - not me

Remember that 300 - 1,000 year lifetime for CO2 in the atmosphere? The amount of CO2 already in our air is far, far larger than the annual emissions. Even if all CO2 emissions had stopped during the pandemic, the change in atmospheric level would have been minute. There was no massive economic stimulus DURING the pandemic so I would suggest either you've misunderstood someone, listened to the wrong source or have just made that up.

According to Scientific researches conducted by GW theorists - not me.

Global warming is taking place and its primary cause is the greenhouse effect acting on human greenhouse gas emissions.

Yes global warming is indeed taking place - with no proof whatsoever that it is caused via human industrial actions. Only theories such as above mentioned and then refuted or redirected by GW theorists upon being faced with facts in regards to e.g. China.
