The burning of fossil fuels is a human-caused contributor to global warming. How do fossil fuels trap heat in the atmosphere and cause a rise in global temperatures?

• Burning of fossil fuels emits carbon dioxide and other greenhouse gases that trap heat.

• Burning of fossil fuels emits oxygen that traps heat.

• Burning of fossil fuels emits water vapor that traps heat.

• Burning of fossil fuels emits heat that traps heat.
