A. increased carbon dioxide in the atmosphere causes global warming

Burning fossil fuels releases carbon dioxide into the atmosphere, which traps heat and causes global temperatures to rise. This leads to climate change, which can result in extreme weather events, sea level rise, and disruptions to ecosystems. Additionally, burning fossil fuels also releases other greenhouse gases such as methane and nitrous oxide, further contributing to global warming.
