how do fossil fuels lead to global warming

Expert Answer:

Burning fossil fuels such as coal, oil and gas impacts on the environment through the production of greenhouse gases. When fossil fuels are burned they produce a range of greenhouse gases including carbon dioxide, water vapour, methane and nitrous oxides. Together, these gases trap the sun's heat in the Earth's atmosphere, acting like a 'greenhouse'. This is called the greenhouse effect. By increasing the amount of greenhouse gases released into the Earth's atmosphere, we are trapping more heat and increasing temperatures.

This increase in temperature is called global warming and is thought to be responsible for global temperature increases recorded during the 20th century and related changes in the Earth's climate.
