Burning carbon requires oxygen (O2), and when we burn an atom of carbon, the required oxygen becomes part of the CO2 molecule. So if the CO2 increase is caused by burning carbon (fossil fuels), we would expect atmospheric O2 levels to decrease at the same rate. And that's indeed what we observe (Figure 1).
How does Carbon Dioxide make the planet heat up?   CO2 is one of the greenhouse gases which contributes to global warming. Scientists consider that these gases go into the upper atmosphere, and trap the reflected sun ligâ¦ht rays.
