Plants turn Carbon Dioxide into Oxygen, that is not a greenhouse gas. But Carbon Dioxide is.
Therefore, wouldn't plants cool the area?

2$\begingroup$ The issue is not that they turn carbon dioxide into oxygen, it's that they store the carbon in the plant. With lots of trees, you make a carbon sink, reducing the amount of carbon in the atmosphere, slowing climate change (warming). There's tons of research of the effect(iveness) of this. $\endgroup$– Jan DoggenCommented May 29, 2018 at 14:17

Plants are natural machines that convert $CO_{2}$ into $O_{2}$ when there is sunlight. This process is known as photosynthesis because photons provide the energy that triggers the reaction, $$6CO_{2} + 6H_{2}O -> C_{6}H_{12}O_{6} + 6O_{2}$$
The question then is where do the plant products,such as leaves, fruits, flowers,roots that are composed of $C_{6}H_{12}O_{6}$ stored? If these plant remains are stored in the ground more than they are decomposed and then release $CO_{2}$ into the atmosphere, then we can positively say they are the natural cleaning robots, sorry super-robots or cleaning freaks!

$\begingroup$ "then we can positively say they are the natural cleaning robots, sorry super-robots or cleaning freaks!" the question was about cooling, not cleaning. $\endgroup$ Commented May 30, 2018 at 12:21

$\begingroup$ Cleaning CO2 from the atmosphere leads to reduction in temperature. $\endgroup$ Commented May 30, 2018 at 14:07

Plants do cool the area around them but it is not due to gas exchange, (not directly) plants provide shade and loss water during gas exchange this loss creates evaporative cooling. oxygen and carbon dioxide diffuse too quickly to much effect on the local environment where they are produced by themselves.

$\begingroup$ Also, the warming produced by CO2 is a long-term, global process. It doesn't selectively affect the local area of the plants. $\endgroup$– jamesqfCommented May 30, 2018 at 18:54
