CO2 concentration in relation to plants
Photosynthesis utilizes CO2 in the production of sugar which degrades during respiration and helps in plant’s growth. Although atmospheric and environmental conditions like light, water, nutrition, humidity and temperature may affect the rate of CO2 utilization, the amount of CO2 in the atmosphere has a greater influence. Variation in CO2 concentration depends upon the time of day, season, number of CO2-producing industries, composting, combustion and number of CO2-absorbing sources like plants and water bodies nearby. The ambient CO2 (naturally occurring level of CO2) concentration of 400 parts per million can occur in a properly vented greenhouse. However, the concentration is much lower than ambient during the day and much higher at night in sealed greenhouses. The carbon dioxide level is higher at night because of plant respiration and microbial activities. The carbon dioxide level may drop to 150 to 200 parts per million during the day in a sealed greenhouse, because CO2 is utilized by plants for photosynthesis during daytime. Exposure of plants to lower levels of CO2 even for a short period can reduce rate of photosynthesis and plant growth. Generally, doubling ambient CO2 level (i.e. 700 to 800 parts per million) can make a significant and visible difference in plant yield. Plants with a C3 photosynthetic pathway (geranium, petunia, pansy, aster lily and most dicot species) have a 3-carbon compound as the first product in their photosynthetic pathway, thus are called C3 plants and are more responsive to higher CO2 concentration than plants having a C4 pathway (most of the grass species have a 4-carbon compound as the first product in their photosynthetic pathway, thus are called C4 plants). An increase in ambient CO2 to 800-1000 ppm can increase yield of C3 plants up to 40 to 100 percent and C4 plants by 10 to 25 percent while keeping other inputs at an optimum level. Plants show a positive response up to 700 to need of 1,800 parts per million, but higher levels of CO2 may cause plant damage (Figure 1).

Cool list, totally unsourced and totally fake.
Typical.

Hey CM, is there any evidence you would ever accept for climate change?
Is there any metric you would believe?

Or is your faith that you are right totally that of a true believer, a zealot of the 'truth'?

Do you think that this means that the greenhouse effect doesn't exist?

Can I take it that means that there is nothing that would ever change your faith that all scientists are lying to you?
There is no science, no facts, no measurement and not even being told to stay inside because of smoke could ever change your mind?

50 years of false predictions are not scientific




dude why are you ignoring the news paper reports making these false predictions? why do you want me to read your links but won't read mine? is that how you debate

As usual, you are posting fake news.
A tweet from a 15 year old before she was well known about a news story where some paper misquoted a scientist and used a click bait headline.


Again, there is no evidence that could ever shake your faith that science is wrong, is there?

franky posting links for others to read while ignoring pictures of newspaper clippings with false climate predictions and constantly dismissing anything he don't like and wonder why don't believe his climate religion

You couldnt live, work, and play inside a greenhouse though.
You would quickly die from CO2 poisoning
that is incorrect
greenhouses typically have 1,000 ppm co2
you exhale 5,000 ppm co2
In submarines, higher CO2 concentrations are permitted, usually 5000- 7000 ppm.
CO2 levels as high as 80,000 ppm can be lethal. OSHA (Occupational Safety and Health Administration) has established a CO2 acceptable exposure limit (PEL) of 5,000 ppm over an eight-hour period and 30,000 ppm over a ten-minute period as a guideline.

CO2 itself is not toxic poor ventilation causes a buildup of CO2 that eventually displaces the oxygen that is available

But thats only true if the greenhouse or submarines are equipped with CO2 removal (CO2 scrubbers)

It says a lot that you don't know the difference between tabloid headlines and real science.
But every time we look at one of your links we find that it doesn't say what you claim, the headline is sensationalized to gain readers and what the scientist, if it was even a scientist and not a politician like Gore, says is entirely different.
If I prove those headlines wrong would you admit you are wrong about climate change?

Of course not, you'd just move on to spamming some other oil funded nonsense and then come back to those same headlines in another month when you've forgotten.

The discussion about climate change is about the greenhouse effect, not the toxicity level of CO2.
Typical science denier that you don't know the difference.
You post about CO2 toxicity in greenhouses as if that was the same thing about talking about the greenhouse effect.
Its not and only a moron wouldn't notice.

Franky once again ignore the news paper clippings and claim they are tabloids and sensationalized you never prove these headlines wrong all you do is whine and whine when you see stories you don't like. These clippings are archived too bad you are too partisan to look anything you don't like. And when are you going to give up using gas and fossil fuel products?

CM, you've already made it clear that nothing can end your faith in the fossil fuel disinformation and science denial stuff you post here.
So why bother wasting time showing what you post is fake?
I did it with the Greta tweet and all you did was move on to something else, like I said you would.

I can't convince a cult member that they are in a cult.
I can't convince you that your faith is wrong.

claiming i am in a cult is you projecting climate alarmists like yourself fit the definition of cults and cult members

i and other members here post multiple evidence showing that climate alarmism is based on fear mongering and brainwashing and censorship of those who don't buy into the climate religion. instead of looking at the facts you instead dismiss them respond with more propaganda and insults claiming they are all science deniers and accusations of shills for the fossil fuel industry(while refusing to stop using gas and other fossil products).

you are not interested in dialog and debate all you do is post propaganda here

no
acceptable exposure limit (PEL) of 5,000 ppm over an eight-hour period is independent of source/use of co2

a greenhouse has plants which absorb C02 so you can frolic all you want in a greenhouse and co2 will not exceed 1000 ppm by a whole lot

a submarine will have scrubbers & o2 generators to ensure Co2 does not exceed 5,000 ppm & O2 levels do not drop below 19.5% & make the sailors lightheaded while they are doing nuclear missile drills

Are you still working on that post about smoking not causing lung cancer?
