How do greenhouse gases primarily affect global temperatures?

• They decrease global temperatures by reflecting sunlight away from Earth.

• They increase global temperatures by trapping heat in the atmosphere.

• They have no effect on global temperatures.

• They cool the Earth's surface by absorbing heat.
