The levels of carbon dioxide in the atmosphere stayed constant for thousands of years because of the carbon cycle, which moves carbon throughout the air, oceans and land. There was also no burning of fossil fuels (coal, oil and natural gas), and nobody had cut down the great forests of the world.
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.

No, global warming results from humans increasing the amounts of carbon dioxide in the atmosphere. There is a certain amount of water vapor in the atmosphere that remains fairly constant and is part of the natural water cycle. In other words, human actions can not increase the water vapor in the atmosphere.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.

Forest fires increase the amount of carbon dioxide in the atmosphere

The atmosphere is very thin and is mostly made up of Carbon Dioxide.
When it erupts, it releases a large amount of carbon dioxide into the atmosphere, polluting it.

Carbon dioxide (CO2) is a greenhouse gas which is causing Global Warming. When there is a great amount of it in the atmosphere, then it absorbs a great amount of heat. This makes Global Warming worse.

Assuming you mean "carbon dioxide", the atmosphere of Venus is made up mainly of carbon dioxide.
