From the United Nations

As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history.

Generating power

Generating electricity and heat by burning fossil fuels such as coal, oil, and natural gas causes a large chunk of global emissions. Most of the electricity is still produced from fossil fuels; only about a quarter comes from wind, solar, and other renewable sources.
