CO2 levels have been increasing over the past 30 years while O2 levels have been decreasing. It follows that more CO2 does NOT lead to increased O2. Your statement is wrong.

No, the CO2 provides an offset to the loss of O2 due to deforestation, degrassification, encroaching desert areas, encroaching urban areas. Simple. Without CO2 we would have a less vibrant plant world and less oxygen to breathe. Edited May 3, 2021 by Ecocharger Quote Share this post Link to post Share on other sites

Ecocharger + 1,473 DL May 3, 2021 (edited) Here is some recent work on this subject, Jay, Read and learn. See how the process works, less CO2 leads to less O2, less oxygen...just like I claimed above, Jay. https://www.eurekalert.org/pub_releases/2021-03/tu-hml030221.php "For many years, the lifespan of Earth's biosphere has been discussed based on scientific knowledge about the steadily brightening of the sun and global carbonate-silicate geochemical cycle. One of the corollaries of such a theoretical framework is a continuous decline in atmospheric CO2 levels and global warming on geological timescales. Indeed, it is generally thought that Earth's biosphere will come to an end in the next 2 billion years due to the combination of overheating and CO2 scarcity for photosynthesis. If true, one can expect that atmospheric O2 levels will also eventually decreases in the distant future. However, it remains unclear exactly when and how this will occur," says Kazumi Ozaki, Assistant Professor at Toho University.

You don't have to be Einstein to figure this one out. "As carbon dioxide levels fall, photosynthetic organisms, like algae in the sea and higher plants on land, will begin to suffer, resulting in reduced production of oxygen. Over a period of just 10,000 years, carbon dioxide levels will drop so much that plant life would go extinct. Without plant life, oxygen levels will also drop, causing a mass extinction event among animals." Edited May 3, 2021 by Ecocharger Quote Share this post Link to post Share on other sites

CO2 levels have been rising for a long time but O2 has been falling, even if it isn't by very much. Too little CO2 will cause a die off which is bad for O2 and there is strong evidence that too much CO2 also causes a die off which is the same bad for O2 levels. Chart plots all the mass extinction events of the last 500 million years against the best estimate of carbon dioxide levels (CO2) at the time. According to his analysis all major extinctions occurred when CO2 levels exceeded a thousand parts per million (ppm). at the current rate CO2 will increase one hundred ppm in approximately 40 years. During past periods of abrupt change — the most recent one occurring approximately 50 million years ago — it took roughly a million years for CO2 to change by one hundred ppm. Thus it is now changing about 25,000 times faster than in known geologic history. Here is a CO2 chart for you. So at current rates we are about 200 years from the mass extinction level. However the rate of CO2 increase is accelerating as we burn more fossil fuels every year. So we will hit the extinction level considerably sooner.

Read what the scientists say above...less CO2 means less Oxygen. The scientists have CO2 and Oxygen going downward together, the drop in oxygen caused by less CO2 for logical reasons. Your own curve above shows CO2 on a DOWNWARD trend until today, to an all-time low, then a fanciful projection IN THE FUTURE going upward. The two charts appear to contradict each other. You give no source for the mass extinctions or the CO2 curve. Who is "his"? Edited May 3, 2021 by Ecocharger Quote Share this post Link to post Share on other sites

No, they describe how CO2 causes photosynthesis in sea-based and land-based plant life and this produces Oxygen....read it again.

Over a period of just 10,000 years, carbon dioxide levels will drop so much that plant life would go extinct.

You have apparently misread "DEoxygenation" in your quote. It means the opposite of oxygenation. No, they used the phrase "great deoxygenation" indicating a sudden event that occurred after a long slow decrease of CO2 and it eventually passing the minimum threshold. Your problem is that this paper is about the Sun expanding and burning off all the CO2. No one is suggesting we eliminate so much CO2 that plants and their O2 production suffer. Plants and animals were doing just fine 300 years ago. However too much CO2 causes ocean acidification which is correlated to mass extinctions. Corals are already beginning to die because of this acidification. They were doing much better 300 years ago!! More CO2 does not always increase O2 as proven by the charts below.
