Can someone explain why CO2 emissions are harmful?
    #20594072 - 09/20/14 06:40 PM (9 years, 6 months ago)

The "toxic" emissions from the burning fossil fuels are supposivley harmful to our enviorment. Can someone explain why? Plants take in CO2 to grow and also to produce oxygen for us humans? I think a crucial thing I might be missing here is what ever else is a by product of the burning of fossil fuels, is this other by product what is harmful to the enviorment? Why are CO2 emissions any worse than us exhaling?

Also, with all of this CO2 in out atmosphere why do we not just get the majority of our energy from artificial photosynthesis?  Or Is the technology just not there yet?

A google search would easily explain this, kind of strange you posted this here.

But it's not good for our atmosphere, specifically and it damages the layer we need that protects us from UV rays, which damages EVERYTHING

No no , co2 doesn't damage the ozone layer,
it increases the greenhouse effect.

chlorofluorocarbons for example damage the ozone layer.

CO2 molecules reflect space-bound radiation, causing the greenhouse effect, or warming. There are other greenhouse gasses in exhaust too like NO2 (nitrous) and CH4 (methane) but they have short half-lives. CO2 lasts forever. So when we pump it into the system, it just sticks around and warms and shit. Plants require so little CO2, that they can't make up for our bad habits (imagine CO2 -> 400 ppm vs. O2-> 210,000 ppm). The ocean stores far more than plants do. And, no, technology hasn't gotten as far as synthetic photosynthesis, or there would be no "energy crisis."

Don't mushies release fairly large amounts of co2?

Hence all the FAE stuff

So this is a huge topic that we could talk about for hours and hours... and I know this is an old thread... but I'm decently knowledgeable on this subject.

In order to fully understand the issue with CO2 emissions, you gotta look at the big picture. CO2 emissions do not directly harm us- it's the other stuff in the emissions. CO2, however, has a lot to do with climate change and the greenhouse effect, so it harms us indirectly via the effects of climate change. Plus add in worldwide deforestation and how it exacerbates the issue.

The ozone layer, identified as such in 1900, is affected by O3 depletion- NOT CO2- and CFC products, invented in 1920's and widely used throughout 1940's for manufacturing of solvents (most notably for refrigerants) were banned a long time ago (with US company DuPont leading the world in manufacturing)... CFC products were great besides the fact b/c that they are awful for the atmosphere b/c of their non-toxicity, non-carcinogenc, non-flammable, etc. (most other solvent substances fail the above tests^^^)....

A good way to go through this is by looking at what our federal government and state/local governments do to address this... so think about the Clean Air Act (CAA), etc.

CO2 is 1 of the 6 primary pollutants that the NAAQS (National Ambient Air Quality Standards) addresses. The other 5 pollutants are sulfur oxides (sox), nitrogen oxides (nox), lead (Pb), Ozone (O3), and "particulate matter". The NAAQS (goes along with Clean Air Act or CAA) focuses on numeric standards for the amount of a substance that is allowed to enter the atmosphere (ex. mobile sources: cars, trucks, trains, etc. but also stationary sources like coal plants, etc.)

NAAQS focuses on primary effects, or direct human health effects, and secondary effects, which are indirect human health effects.

So long story short, acid rain is caused by sulfur dioxide mixing with water in the atmosphere, which makes sulfuric acid (SO2+H20-->H2SO4). A lot of this comes from coal-fired power plants (like in the midwest for ex), and negative consequences occur downstream (brought by wind) in ecosystems and their lakes and forests, etc. So, the coal plants put out a ton of CO2, but it's the Sox from the coal (coal contains sulfur) that's the problem.

Mobile sources (cars, trucks, etc.) are regulated in many different ways by addressing the point of manufacture- ex. catalytic converters were invented to help this problem. They banned Pb in gasoline years ago, and addressed "fleets" to set a certain MPG average (which didn't really change from the 70s until recently, unfortunately).

Look up CAFE (corp avg fuel efficiency) and stuff like that.

Cheers from:sunny:SWFL

Co2 emissions are not harmful in the way that proponents of catastrophic anthropomorphic global warming would have you believe.

Climate change not so much global warming as change. I am a climate scientist for the government I am quitting because evil conservatives in power don't care and collect that data for publicity but don't care.

I'll tell you the reason why it is super bad other than the reasons given about trapping energy from the sun in our atmosphere. All the co2 that has nowhere to go dissolves in the oceans. When this happens, carbonic acid is formed in the water. When this happens, the oceans become more acidic. Sealife needs to control its pH the way freshwater fish do. When the pH drops too low, dire consequences will follow. Think collapse of ecosystems and death of many species. This doesn't seem too bad for humans but think of how much fish we eat and that ocean plants recycle most of the co2 we output into O2, not the land plants we assume do most of the work. For more info here is a good article I found

Go to Bi-Ca then click carbon dioxide in the ocean and atmosphere

Yeah the effects on coral reefs is a huge thing to point out acidfication of the ocean and rain to simplify what he just said

The coral reefs are turning a different color in places where the acidity is very high

The reason is that CO2 has an electric, molecular dipole, or in other words, it has polar bonds. There is a partial negative electric charge on the oxygen atoms and a partial positive electric charge on the carbon atom. This is caused by the effective nuclear charge difference between the C and O atoms. This also causes the oxygen atoms to oscillate with a frequency back and forth, because the partial negative electric charge of the oxygen atom is pulled toward the partial positive electric charge of carbon atom, but then is repelled because of electron repulsion forces within the polar covalent bond. You can imagine the oxygen atoms attached to carbon as though by springs.

Photons are a source of electrical energy. These oscillation within the CO2 molecule have a frequency that is able to absorb and emit electromagnetic radiation in the infrared frequency. The frequency of the molecular oscillations are the same as the frequency of infrared electromagnetic radiation.

This makes CO2 infrared active. Because CO2 is able to absorb and emit infrared radiation, it traps this radiation within our atmosphere, which then raises the global temperature.

O2 and N2 do not have polar bonds, being diatomic molecules. They do not oscillate, so they do not absorb infrared radiation. It just passes through them.

This absorption and emission of infrared radiation is what causes the green house effect. H2O vapor is the most infrared active atmospheric gas, having very polar bonds and a high molecular dipole. If we didn't have the green house effect, the earth would freeze over at night and burn during the day.

So, the green house effect is very essential to life, but when you introduce copious amounts of CO2 into the atmosphere, you will cause global climate change, which is not very good for life. For life does not respond well to drastic, very fast changes that are occurring right now.

The proof comes from IR spectroscopy. We see here an admission spectrum of some atmospheric gases.



You will see from the spectrum that O2 does not absorb much light at all. The spectrum for N2 will be similar, because they are both nonpolar, diatomic molecules.


I hope you have learned something about chemistry today. Global warming is not open to interpretation. It is without a doubt a real phenomenon. If you are arguing against it then you are arguing against what is the foundation of modern chemistry and chemical analysis. That is spectroscopy.

CO2 doesn't last forever, though, and can dissolve in water in the atmosphere, rain down and turn into carbonic rock like calcium carbonate, so it is unlikely that earth will ever experience a runaway greenhouse effect like observed on venus, but this process of recycling CO2 is very very slow. We pump billions of tons of CO2 into the atmosphere every year.

CO2 can also react with water to form carbonic acid, which can cause acid rain and acidification of the ocean.

We are not stewards of the earth and will most likely experience catastrophe.

Maybe CO2 emissions are bad because billions of dollars are spent telling people they are bad?

Be very slow to believe. The Buddha advised people not to believe anything unless they personally gain the evidence to understand it. It's the best antidote to people trying to get your hard earned money off you.

Image the world we would be in with out the Clean water act and clean air.

Back in the day you could light rivers on fire in america

Go look at china now



Yup its probably just a waste of money trying to get people to believe that there are serious environmental problems.

Do we have to wait until corps cant grow to accept that we fucked up agriculture then slowly starve to death rather then just do shit right?


Cornucopia industrialism we kill this planet and humans for sure, im sure life will emerge tho


If your not sure about the Carbon acidifying the ocean get some carbonic acid and some distilled water, check the pH or in fact get sea water even better. Check the pH then start scoping it in and testing the pH. Or you could burn a bunch of stuff in a closed system and check if the pH has changed from your emissions


Its hard to believe people won't accept that the ecosystem wasn't built to handle all the emissions from cars and factories or all the chemicals dumped in waters and land.

We're pushing the system further out of it's pre-industrial equilibrium than I would consider safe. Other posters have covered the topic eloquently enough, sorry for the tin foil hat guys in this thread.

Well something one should consider its not just CO2 its GHG and if climate changes to the point it kills trees due to drought or temp shift, cant say thats good.

higher CO2 means higher ocean acidity(carbonic acid). eventually, anything that uses CaCO3(think crabs, clams, coral, etc.) wont be able to hold a skeleton together anymore. poof. its already becoming a problem with commercial oyster farms(the larvae cant form their first shells properly), so its not some far fetched in the future sorta thing either
