You must be really proud of the extra pollution that posting this pointless, stupid thread caused.

>>15949896
CO2 isn't a pollutant, its an extremely important an necessary atmospheric gas, we barely have enough of it in the atmosphere as it is currently and would be far better off if we had 400% more than we currently do.

A cycle like everything else in nature:
>oil pumped out of earth
>used as fuel
>released as CO2
>absorbed by trees
>driven back into earth
>repeat
The "takes gorillions of years" fossil bullshit is just that.

>>15949903

why 400%/what would it improve?

>>15949888
Man water is so good. It’s so good for people, they keep whole jugs of it in the fridge and buy big devices to dispense it. Yet science says we shouldn’t live underwater? I say we should show science and start breathing water. After all, it’s good for us, so any quantity and distribution of it must also be good for us.

>>15949888

Comparing the thin atmosphere of Mars to Earths in equatable terms is the most retarded thing I've ever read. Kill yourself as your new years resolution.

>>15950102
you are psychologically unhinged and violent and because of that you're mentally ill opinions carry no weight

>>15950123
I understand that you're mad that you didn't think of Mars having such a thin atmosphere so most heat escapes into space, but you'll get em next time champ!

>>15949888
You're bitching at nomenclature, basically.
CO2 absorbs and re-emits infrared radiation, and in the process, it prevents about 50% of the infrared radiation coming from the Earth's surface from passing through and escaping out to space, trapping that energy within the atmosphere and the Earth.

>>15950256
Additionally, a glass greenhouse keeps warm not only by preventing convention, since glass literally acts with infrared in the same way that CO2 does, therefore, "greenhouse effect": glass molecules absorb infrared radiation and convert it into heat energy, which causes the glass to warm up. At the same time, the glass molecules also emit infrared radiation in a random pattern, which prevents the radiation from passing through the glass. In short, glass acts as a kind of barrier that blocks the passage of infrared radiation, while allowing visible light to pass through.

This thread is full of retards and useful idiots

>>15950623
Are you upset because everyone knows that CO2 is a greenhouse gas and doesn't believe your absolutely poorly thought out reasoning for why it's not?

>>15949919

I’ve always thought this whole concept of a greenhouse effect was flawed. I have no way of formally proving that or articulating why but it just doesn’t seem like it makes much sense when you think about it.

>>15949888
Earth cannot convectively cool itself in the vacuum of space, so the cooling of Earth is regulated exclusively by how much EM radiation from within can escape, just like a greenhouse...

Mars is lacking water vapor, which is a far more powerful greenhouse gas (for instance, you will notice that cloudless nights are much colder than overcast nights, all else equal). Its overall atomospheric pressure is way lower as well.

>>15951625
Even on cloudless nights there is still a lot of water vapor in the air, there is nowhere on Earth - not even in the most arid desert, that cools off at night even half as rapidly as Mars does.
And Mars has massive amounts of CO2 in it's atmosphere so the fact that Mars cools off so rapidly eliminates the possibility of CO2 being a greenhouse gas

I understand these threads now. It’s to piss of the environmentalist who refuse to admit that climate change should be tackled like every other problem: With a free market.

>>15949888
does wonder to aquatic plants as well. was a bit into aquascaping some years back and I generated CO2 with yeast and sugar. once I added that plant growth went crazy

>>15952108
duh. what do you think photosynthesis is

>>15951988
You're just being willfully stupid at this point in ignoring the fact that Mars' atmosphere is over 100 times thinner than earths.

>>15952140
>Mars' atmosphere is over 100 times thinner than earths.
It isn't
Mars' lower atmospheric pressure is in part attributable to Mars' lower gravity. If Mars' atmosphere was as low density as you're claiming it is then it wouldn't be able to generate the massive dust storms that are common on Mars

>>15952152
Yes it is you dingus lmao

>>15952156
You can't do math and don't understand physics, are you a negro?

>>15950256
every molecule and atom absorbs and reemits radiation, co2 is no different from any of them. co2 is an insignificant trace gas in earth's atmosphere, it doesn't cause global warming

>>15949888
yeah

>>15953567
Right, the main difference between CO2 and nitrogen is that nitrogen is a large fraction of the atmosphere and CO2 is virtually nonexistent

>>15955452
co2 would be the most valuable form of insulation on the planet if an atmosphere of 0.0005% co2 was able to prevent all heat from escaping. you could just put some balloons of co2 in the walls of your house and save fortunes on the heating bills.

>>15949888
But greenhouse effect of CO2 is caused by the fact it does reflect energy back to ground when it's released in form of photons to go out of planet.

Also have you noticed there's no water in atmosphere of mars, so your theory is practically invalid?

Does this retard not realize how thin Mars' atmosphere is compared to earth? That's the most bullshit analogous thinking, OP. You should shoot yourself for equating percentages to mass.

>>15951555
Last I checked, "life" included more than the plant kingdom.

>>15949888
co2 doesn't exist in the atmosphere because co2 is plant food.

Wouldn't thermal energy radiate back into space as much as it does into the atmosphere? Or even moreso into space due to a more significant energy gradient?

Also, why would carbon in the atmosphere have a greater heat capacity than carbon in the earth? It's the same amount of mass within the system.

Not trying to be contrarian here. I'm 50/50 on the matter. Couple of points don't make sense to me.

>>15957674
Ok, let me be nice to you:
>Wouldn't thermal energy radiate back into space as much as it does into the atmosphere?
Scenario A, no greenhouse effect:
100% of the energy gets radiated to space
Scenario B, with greenhouse effect:
Some energy gets radiated back to the atmosphere, some gets radiated to space

Your point is not wrong, but it has zero implications. If ALL energy was trapped in the atmosphere, then the temperature would rise to infinity anyway. So it should be obvious that this isn't the case. CO2 only absorbs a certain part of the spectrum and in an oversimplified of a thin layer where that radiation is absorbed, half gets sent back to earth and half gets sent to space.

If you do the maths, you'll find that this single thin layer doesn't describe our observations well enough anyway. There's an exercise to calculate the equilibrium temperature without an atmosphere, with a window pane at a certain radius around the earth and with two window panes. The two give you the right order of magnitude. If you want to calculate it yourself, make the following simplifications: light comes only in two wavelengths, IR and visible. The Sun's spectrum has 50% of either. The window pane(s) absorb 100% of IQ and none of the visible light. The absorbed IR is re-emitted in a random direction as IR, both by earth and the window panes.
I don't remember if you need the albedo for it, but maybe calculate the equilibrium temperature assuming that the earth doesn't reflect any light and see what comes out.

>>15957699
not that anon

>>15951555
trees can't grow if they die from fires, floods, drought, salt water intrusion, etc.

>>15949888
When you burn things they produce CO2 and else

Even if CO2 WAS HARMLESS, which isn't it will still tell us where pollution is happening

>>15958579
>drought
plants require less water to grow in a higher co2 environment
>global warming causes floods
>global warming also causes droughts
>global warming causes more hurricanes
>global warming also causes less hurricanes
>global warming causes sea level rise
well sea level isn't rising so that proves global warming isn't happening
>global warming causes fires
no, thats global warming activists committing arson

>>15958587
>Even if CO2 WAS HARMLESS
CO2 is beneficial, it's presence is an absolute necessity for life on Earth. Enhancing the availability of CO2 in the atmosphere facilitates plant growth while also allowing plants to use water more efficiently which in turn allows nature to flourish and produce more effectively and prolifically. CO2 is not only harmless, it is extremely beneficial. Anyone who is concerned about the natural would should be ecstatic at seeing enlarged portions of atmospheric CO2 because that means that every acre of nature will be more productive than it has been previously.

>>15959469
Water is necessary for you to live, but you can still poison yourself with water if you drink too much of it.

>>15959469
So what your long term strategy for humanity is, what exactly?
CONSUUUUUUUME?

Ok. Good plan.

>>15959477
right, but the point at which lack of CO2 becomes a detriment is about 200ppm and the point at which CO2 becomes excessive is well over 2000ppm and we're currently at around 400ppm, so clearly we'd be better off in the middle of that range with over 1000ppm.
with twice as much CO2 in the atmosphere the numbers on picrel chart would all double, nature would flourish in ways no human has ever witnessed, farmland and wilderness would all be twice as productive and ever living creature on the planet would be far better off

>>15959481
shouldn't you be busy searching the internet for pictures of people larger and wealthier than yourself to get angry at?

>>15959481
Theres nothing more consumerist than belief in the global warming narrative
Its been shilled to death by more celebrities than Coca Cola, Disney and the rest of the consumerist goyslop continuum combined and the end goal of everyone who believes in the hoax (or feigns belief in it) is to have an excuse to acquire massive resources from the rest of the world so they can consume them themselves.

>>15959816
>claims and empty promises without sources
Many such cases

>>15959887
This, every major media outlet and government agency is constantly shilling global warming doom, you'd have to be a total NPC to buy into it

Government/corporations are literally running a fucking ponzi, and they have an aversion to any science or truth that raises questions about their long term strategy (there is literally no long term strategy).
At this point if you're not highly skeptical of literally every single thing the government/corporations wants you to believe (including that), then you'd have to be an idiot. And I don't give a single fuck if it is a central tenet of your weirdo victim complex desert cult.

This, healthy plant kingdom, healthy everything else. Plants can live without animals, but the reverse is not true.

>>15961513
>healthy plant kingdom, healthy everything else. Plants can live without animals, but the reverse is not true.
Your logic is so flawed it hurts. If
Unhealthy plants => unhealthy animals,
then
healthy animals => healthy plants
and of course
healthy animals => healthy animals
So,
healthy animals => healthy everything
but
healthy plants =/> healthy everything, since you can have healthy plants and no animals.

>>15949888
>that is "the greenhouse effect". If CO2 caused "the greenhouse effect" then Mars would be far, far hotter than it is because Mars has over 3000% more CO2 per unit surface area in it's atmosphere than Earth does, however Mars has no measurable greenhouse effect, because CO2 is not a greenhouse gas. Even if CO2 were a greenhouse gas,

Mars is significantly further from the sun than earth is. Mars' atmosphere is also also a lot thinner than Earth's. Please do your homework before starting a thread.

>>15961618
He's been posting this nonsense for over a year. And in every thread, there's someone like you correcting him, explaining that mars does have a greenhouse effect and that in addition to the amount of CO2, the density of the atmosphere plays a role in heat retention. Mars' greenhouse effect of 5°C is in perfect agreement with even basic atmospheric models. At this point it's really cheap trolling that still seems to be effective.

>>15961622
but that is workforce, so if they want even more the rest have to do with less.
do currently living people want even more peers or less?
this debate is shit because we're dealing with an issue for which the solutions vary depending on what is desired as far as population growth is concerned.
we want more people then currently living people need to share those resources with more people. they get less going forward.

>>15949888
>Mars would be far, far hotter than it is because Mars has over 3000% more CO2 per unit surface area in it's atmosphere than Earth does
it also has 0.6% the atmospheric density of earth

>>15961823
Mars' lower gravity has a lot to do with that lower density.

Which is it, are you dumb or are you a liar?

>>15963412
I missed the "average max temperature" lmao. They use such weird quantities because all others would show an increase. Recently there was one which was like 90th percentile of all weather stations in a certain network in 12 select states for the months October, November and December or something similar.
To be honest, I have to admit that it sounds fun. Massaging the data enough to find nonsense. Reminds me of the "chocolate makes you lose weight" study.

>>15963429
