Question

what is the percentage of co² in the atmosphere​

Answer 1

Answer:

CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed.

• $~ \sf\: CO_2~$ came from humans burning fossil fuels.

• The carbon from burning fossil fuels have a different isotope signal (radioactivity) than $~ \sf\: CO_2~$ coming from natural sources. It’s like DNA proof in a murder investigation.

• The carbon in the atmospheric $~ \sf\: CO_2~$ contains information about its source, so that scientists can tell that fossil fuel emissions comprise the largest source of the increase since the pre-industrial era.
