The most obvious and indisputable cause in the last 150 years is the addition of carbon through fossil fuels and land cover changes by humans. Other causes are changes in the carbon cycle, minor by comparison. This includes a global ability to uptake more carbon in forests, as well as the inability for the oceans to take anymore carbon.
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.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
Assuming you mean "carbon dioxide", the atmosphere of Venus is made up mainly of carbon dioxide.
Carbon Dioxide
Cars and factories.
the atmosphere of palnet venus is mainly contained by; carbon dioxide and a small amount of nitrogen.
Carbon dioxide is a naturally occurring compound in the atmosphere. Total amount has to be in the trillions of pounds. There is a more in depth answer at the link below.
