Yale did an interesting study linking increased C02 levels with impaired cognitive abilities:

Elevated levels of carbon dioxide in indoor settings can have a detrimental effect on decision-making abilities and work performance, according to a new study. In a series of tests, U.S. researchers exposed 22 healthy adults to different levels of carbon dioxide concentrations (600 parts-per-million, 1,000 ppm, and 2,500 ppm) in an office-like room. Under each condition, the participants were asked to take a computer-based test that measured their decision-making abilities. According to the findings, published in the journal Environmental Health Perspectives , the participants’ performance declined notably on six of nine tests when CO2 levels were increased to 1,000 ppm; performance declined substantially on seven of the tests when levels were bumped to 2,500 ppm. Earlier research has associated increased student absences and poorer performance with higher CO2 levels, said William Fisk, a researcher at the Lawrence Berkeley National Laboratory and co-author of the study. “But we never thought CO2 was actually responsible,” he said. “We assumed it was a proxy for other [pollutants].

I wonder if this means as C02 levels increase and oxygen levels plummet due to global warming and the dying off of vegetation, we will suffer impaired cognitive abilities as well?

If that's true then the prophetic ideas expressed in Buddhist and Vedic literature will be true: degenerating mental faculties over time.

I don't doubt that atmospheric CO2 levels are likely to be on the increase. However, the partial pressure increase could only be negligible. In addition to this

our own physiological responses at such a minute level of increase in partial pressure would offset any deleterious effects. While a very interesting and thought provoking study,it certainly

will take decades of studies to come to a real conclusive stance surrounding what is suggested by this study.

Stem cells will be able to cure a lot of things in the future including cognitive impairment.

Those stem cells still need oxygen.

Everything is going to be alright.

I don't know about what you've learned, but I've always been taught to be super cautious to be drawing vast long=term conclusions from a single study. Results must be repeated over time and with different populations for a start and then we can start worrying a little.
