How do fossil fuels contribute to global climate change?

Fossil fuels create many harmful gases that contribute to global climate change in the form of global warming.

Explanation:

Fossil fuels are primarily used for vehicles as fuel, and is converted into power for the vehicles through a method called combustion. This method burns the fuel. The burned fuel releases many different harmful gases, primarily Carbon-Dioxide, which is a greenhouse gas. Greenhouse Gases keep heat trapped in the troposphere, preventing it from dispersing into space. This heats up the earth as more and more heat becomes trapped.
