What were the PPM in the 1970s?
275-280 ppm, depending on which lab and what day-of-year: As plants grow up north (and there is really very little suitable land area for plants below the equator) in the spring and summer, Co2 goes down a lot. As the leaves and fruit and limbs for and decay up north in fall and winter, CO2 increase each year.
Thanks Robert.
I appreciate the figures.
At what point that CO2 become problematic for humans?

Higher levels of CO2 have another major benefit for plants. The stomata are the pores on each leaf that absorb CO2. They have to be larger when the level of CO2 is lower. This allows more evaporation of water. With higher levels of CO2 the stomata are smaller and lose much less water. Some of the most important new plant growth is along marginal areas on the edges of deserts where new plants are making major inroads because they can now survive on much less water.
That is more the truth than any of the global warming advocates have said or are saying. You can see it if you just look around in the woods.
I have absolutely no scientific training beyond what they taught me in a “gut course” in botany in college to satisfy my science requirement.
But I have been arguing this for years with Global Warming idiots. We may see the tropical climate in more northern climes with palm lined beaches in Alaska for resort tourism.
Or opening up vast areas of Siberia and Canada for productive farming instead of ice fishing.
But...but..aaawww! Now they’ve gone and made climate alarmists look stupid! Quick! Take away this team’s credentials and pronounce any research they’ve ever done as false and invalid, in 3...2...1...

Thanks Robert A Cook PE.
You have been pinged because of your interest in environmentalism, alarmist wackos, mainstream media doomsday hype, and other issues pertaining to global warming.

I’m going to BBQ some steaks tomorrow so that I can do my part by putting CO into the atmosphere and block the sun making all those damn CO2 producing plants die.
We can’t just have things just getting greener all the time.

“At what point that CO2 become problematic for humans?”
With regard to what we breathe, air (sea level?) is 20.9% Oxygen. OSHA says that at levels below 16% one needs to use artificial air (SCBA, etc.). You can survive for a little while at levels as low as 11% without major complications.
With CO2 only composing about 0.04% of air, it has quite a bit of increasing to do before it will affect our breathing. Exhaled air is still in the range of 14% to 18% oxygen (quick web search) - which allows for under-water “buddy breathing”.
Aspen, CO the O2 level is about 15.5%.
I worked on a site at about 14,500 feet for three months - the chart says that was about 12%. It sure felt like it for the first two weeks! (Physical labor). That was almost 25 years ago - it would probably kill me today!
I didn’t realize the O2 percentage was so low. I’m glad that it was overseas. OSHA probably would have required the use of a 20 pound air tank the entire time!
Greenhouse CO2 systems raise the levels to 3-4X atmospheric levels. People pay money for this, and now we’re getting it at a lower level for free.
The reason that cooler oceans absorb more CO2 and wamer release more is Henry's Law. CO2 is not a "coolant".
Yes, it has already. See The Greening of the Sahel.
Yes, CO2 starvation was a serious threat to the planet in the last million years. Only (maybe) one other time in geological history did we have CO2 this low. We can blame the ice age (which we are still in) along with the Himalayas and other mountains for sucking CO2 from the atmosphere.
Entirely correct.
