“the oxygen levels in the atmosphere jumped from around 15% to around 19%. For comparison, there is 21% oxygen in today’s atmosphere. We really don’t know what might have caused this increase, but we also see a drop in CO2 levels at that time.”
CO2 causes explosion of plants which eat it and produce Oxygen.

CO2 causes explosion of plants which eat it and produce Oxygen.
So we can expect another rise if the levels keep on rising like that
How did oxygen get INTO rocks?
And gee, did atmospheric O2 rise because photosynthesis increased as CO2 levels rose?.
Wouldn’t a rise in dinosaurs also have contributed to a rise in methane gas?
I wonder if there's a farting correlation?
A minor whiff of one, possibly.
The Takers have yet to explain how a very slow crawl towards optimal CO2 concentrations will somehow destroy the Earth... in 11.5 years now... and why we need to turn around and get further away from optimal conditions for plants. But they sure do keep trying hard to make multi-trillion-dollar pots of gold for some reason. Healthcare, college tuition, CO2 control, Reparations, etc etc etc... all have one thing in common: a huge pile of money for the DC swampmonsters to skim their meager 10-80% from the top.

The study even starts out with the usual Leftists nonsense:
Background
"It is widely evident that global atmospheric carbon dioxide (CO2) concentration has dramatically increased since the nineteenth century industrial revolution, elevating by about 1.6 ppm/yr. during the past five decades [1, 2]. According to the most recent report released by the Inter-Governmental Panel on Climate Change (IPCC, 2013), global atmospheric CO2 levels have increased from the pre-industrial level of 280 ppm to the present level of nearly 410 ppm and the growth rate of CO2 concentration is projected to be accelerated with an unprecedented pace of ∼1.0 ppm/yr. [2,3,4]. Moreover, the global atmospheric CO2 concentration may even reach 1000 ppm by the end of this century and nearly 2000 ppm by the end of the next century if no effective control measures are implemented [4]. This elevated global atmospheric CO2 concentration may not only cause climate warming, but also cause profound impacts on the net primary productivity of agricultural and natural ecosystems [5,6,7,8,9]. "
Results
Elevated CO2 effects on plant biomass
We found very strong CO2 fertilization effects on the aboveground and total biomass of the three species. The optimal CO2 levels for the aboveground biomass were 945, 915, and 1151 ppm, and for the total biomass were 915, 1178, and 1386 ppm for tall fescue, perennial ryegrass, and Kentucky bluegrass, respectively (Fig. 1).
Have any of you old timers (I include myself) noticed how much more aggressively poison ivy is growing these days? They love that extra CO2.
It is a self-contained system, and it has lasted billions of years, the least people can do is just STHU about it. As the physics-inspired ecology rule #1 goes, one can change the environment, but can't change the rules by which it operates. As far as ppm CO2 figures go, the figure of 415 was taken in Hawaii -- and there's a live volcano bubbling away right there. I am reminded of the old George Carlin Hippy-Dippy weatherman routine -- "it's 75 degrees at the airport, which is stupid, because no one lives at the airport."
That means I’m a Brontosaurus after a thanksgiving meal.
You should see the kudzu down here in the South.
For the first time, I have some growing on my lower property. I sprayed the heck of it this week with evil, scary Roundup.
Bronto sandwiches would have been better, if it weren't for all that bread.
Think of the gallons of barbecue sauce required for one bronto sandwich.
Big, big rotisserie.
