This is NOT good.
CO2: I believe is a lagging indicator of the true cause of climate change ... the sun.
CO2 is plant food. It is absorbed by growing things. But it is also part of a cycle. If it is a warming cycle CO2 will be released and plants will prosper. After extended mediocre solar activity the levels may start dropping as not enough is being released from reservoirs like the oceans in the natural cycle.
Then as things start to finally get cold ... we are screwed.
Though granted it would take time.
Aside: given people’s short term memory probably time enough for anthropogenic global warming to be recast as anthropogenic global cooling.
Don’t worry. Our contribution to worldwide carbon emissions in either direction is totally insignificant.
The O2 cleaved from the CO2 by the plant during photosynthesis is emitted back to the atmosphere and then used by animals for respiration and the waste product of respiration is CO2, which is sent back into the atmosphere to be used by the plants. You blood pulls o2 thru the lungs and it makes the blood bright red and delivers it to the cells and picks up the co2 from the cells which makes it rusty red color and the co2 is emitted by the lungs.
That is the carbon-oxygen cycle on earth. That is not a problem.
The problem is that in earlier times, over millions and billions of years, huge amounts of these carbon compounds were produced and stored in the ground as coal, oil, and natural gas. They are truly fossils
Over a very short period of time huge amounts of these materials were dug up and burned. we have burned coal for only 300 yrs, oil for about a 100 years, and nat gas for even less.
And over this short time period the earths population has grown exponentially to 7 billion and will reach 11 billion by 2100. And as more nations grow their economy more will need fossil fuels
