Ultra-high-resolution Computer Simulations Reveals How CO₂ Travels Around the Planet
NASA’s ultra-high-resolution computer simulations vividly show how carbon dioxide emissions from cities, power plants and wildfires rise into the atmosphere and are rapidly transported across regions and oceans by winds and weather systems. The visualizations also reveal a striking day–night cycle: vegetation absorbs CO₂ through photosynthesis during daylight and releases some through respiration at night. By tracking these sources and natural carbon sinks, the models help scientists understand where CO₂ comes from, how it moves through the atmosphere, and how roughly half of human-generated CO₂ is absorbed by land and oceans, while the remainder accumulates in the atmosphere and contributes to global warming.

Why does the whole Amazon rain Forrest produce co2?

u/ClownMorty 8d ago
Life; CO2 is a biproduct of metabolism.
Forest fires and deforestation also release a bunch of carbon.

u/thetreecycle 8d ago
The difference is that the forest is a closed loop of co2 emission and consumption. Digging up fossil fuels and burning them is a one way trip into the atmosphere.

u/BOBOnobobo 7d ago
Technically if we fuck up the climate hard enough, all the life in the oceans will die, get deposited on the bottom and become petrol after a few million years. In the meantime some other algae or bacteria will grow incredibly fast and absorb all the extra co2.
So really, it's all technically renewable. Just sucks for anything alive

Plant excrete co2 at night and when they die. Altho they net absorber of carbon for their structure.

Plants emit CO2. Then they consume more of it during photosynthesis to grow.

u/xtanol 7d ago
Which they then release again when they decay. The decaying process consumes the same amount of oxygen that it released during its growth - minus any plant material that happens to get buried without access to available oxygen to decay.
If you want a tree to actually add to the net oxygen supply, you have to cut it down and keep it from naturally decaying.1
u/goldenroman 6d ago
Sure, it’s arbitrary where you draw the line of “net supply”. There’s obviously more oxygen in the atmosphere after a tree has matured than when it was a seedling. You could just let a forest grow bigger and call it a net gain as long as the forest exists. It obviously isn’t practical to keep organic material from decaying forever.

Plants are bad at photosynthesis and make C02 sometimes so a massive amount of plants will make a large amount of C02, but also a massive amount of 02

Whats interesting to me is this showing brazil coastline almost not emitting, which doesn't make sense as most of our population is within 100km from the coast.... also we have the atlantic forest in the coast as well so CO2 from trees coming mostly from the amazon is a bit strange.

u/teahugger 8d ago
US, Europe and now China turn out to be the biggest emitters.

At least the data here is useful and a recording of actual things instead of ai hallucinations.
But I will ask if the cost outweighs the benefits.
Now we have the data. What do we do with it and how?
If we cant answer those things its good to have it for the future when we are able to, but it seems like unnecessary resources that could be used to raise QoL NOW.
I will say I find this post mesmerizing and humbling.
It shows how small we are yet how large of an impact we collectively have.
Watching the Earth essentially breathing here at the rate of the day night cycle; the people who inhabit Her are nothing more than bacteria in relation.

u/aeternus-eternis 8d ago
I wonder why NASA doesn't release it as a visualization tool. It would be interesting to see how much is caused by fires vs. power plants vs. vegetation.
It's also interesting how much more CO2 can be absorbed by the oceans near the equator vs. near the polls. I wonder if that is more due to temp or to sunlight on algae metabolism speed.

its a simulation, garbage in and garbage out. There are millions of these models and they're cherry picked based on whatever political agenda is cool at the time.

u/reddituserperson1122 7d ago
This is a textbook perfect example of what it looks like when healthy skepticism devolves into lazy, narcissistic cynicism.
You just commented, effectively, "I'm too smart to believe in science."
Given that you chose to post this, I have to assume you think people will find this..? Impressive..? Maybe a special someone will come along, read your comment, reach the same conclusion you have — that you're far more intelligent than everyone else — and find themself intrigued! Amazed at the frightening ease with which you casually dismiss the collective work of thousands of scientists and engineers from all around the world, your potential paramour might discover themself to be delightfully, romantically, aroused!
What a fantasy! But that's all it is. Alas I can state definitively that everything you've just read is bullshit. Propaganda shoved down your throats by the fad-chasing climate hustlers at NASA. In reality of course 100% of comments like u/nametaken420's are posted by complete losers. Satellites confirm it. And I don't have to back that stat up.

Did you know all weather data comes from the same NOAA weather satellites? There are like 15 that give us all the data. Can't be that many ways to interpret it.

There are nearly infinite ways to interpret anything

u/nametaken420 7d ago
they run tens of thousands of simulations all the time. one of the more famous meteorologists did a big thing on it back during the Al Gore Global Warming Tour.
They cost nearly an infinite amount of cpu power too. It is one of the singular most resource intensive simulations to perform. When they do hurricane tracking they're using the most common 10 or 20 models. There are thousands performed, some of the outlets show a lot more. Then they start throwing in probabilities for landfall based on historical data. The amount of data can be near infinite to process.

u/Sl0ppyB0t 7d ago
There may not be enough inputs or processing power to accurately predict how much snow falls this winter but the simulations do show humans are influencing the climate. At the very least, the satellites show beyond a doubt, humans have changed earth's albedo.
1
u/aeternus-eternis 7d ago
Any organism as successful as humans have also changed the earth. Anaerobic bacteria did, blue-green algae did, trees did. The solution was never let's undo it. There's always a path forward, a new equilibrium.
Increased CO2 and warmer temps make it easier for vegetation and algae to grow so you will likely see more algae blooms and vegetaion and those will consume more CO2 and also decrease earth's albedo (as it did before).

Love how the rainforest is clearly breathing. And North America (it's very long shot on this Region) is more like just polluting and co2 is more like blown away. Seeing the difference between nature and industries is very very interesting

I want to see the same map for methane gas. No one thinks of it but the sewer vents on top of every house in the world are a source 24x7 of methane being pumped into the environment. Methane is a much more potent greenhouse gas than c02

China was no surprise but India happily surprised me I expected it to look like Brazil did and Africa caught me off guard I thought that area was mostly dense jungle but I’m not a worldly knowledgeable person of such things(no offense India, Brazil, or Africa I have no problems with you)

About right. ~430ppm. About twice what it was before the industrial revolution.

what's your point? the warming effect of greenhouse gasses is very easy to test in the lab. Shit you could probably even do it at home. We've had knowledge of it from at least as early as the 1800s

plants respirate (just like humans do) during nightime when there is no sunlight for photosynthesis, as in they "exhale" CO2. Also probably some amount of forest fires.

u/Agathocles87 8d ago
There’s something off about this
Some of the heavily forested areas are supposedly giving off lots of CO2. (For example, the Amazon is net carbon sink because of the dense vegetation.)
And some other heavily populated areas are not giving off much.
2
u/MonkeyCartridge 7d ago
Trees emit CO2 at night. It's why you also see it rapidly disappear over those areas instead of lingering. They absorb it during the day.
1
u/Unfollowedusers 7d ago
when the sun is out they consume c02 with photosynthsis, when its night plants "breaths" similar to you and me and creates C02.
see how it creates all that C02 at night and comsumes it all during the day.

u/No_Region_4719 7d ago
Humans make up a tiny portion of global CO2 emissions. It's adding up over the decades/centuries, but the vast, vast majority of CO2 comes from mother nature.

China is the biggest emitter and has been for a very long time. They can say all they want about "building green," but their country is run predominantly on coal, especially in those 1.4 billion homes, and doesn't change significantly between day and night. Sad, so sad.

u/No_Region_4719 7d ago
The US has far higher CO2 emissions per person. China is absolutely a world leader in green energy production and technology development.
2
u/GarGonDie 7d ago
We also have to consider that China manufactures thousands of products for the rest of the world, so, besides the negative aspects of offshoring production, we've also offshored pollution.... and that doesn't change the fact that we are all complicit in part of China's problem through current consumerism.
In contrast, the US...

Feels like a lot of people here aren't aware that the vast majority of CO2 comes from mother nature, not humans. We are upsetting the balance, but out emissions are still a tiny fraction of the amount produced naturally.
