"Greenhouse Effect" is the effect of greenhouse gases, primarily water vapor, that hold heat close to the Earth. It's mostly a natural process and is necessary to keep the Earth reasonably warm.
"Global Warming" is excessive greenhouse effect caused by man, primarily by releasing carbon dioxide (another greenhouse gas) from burning fossil fuels. Left unchecked it will flood coastal cities and severely damage agriculture.
The graph below is good. The tiny teeth are plants naturally controlling the greenhouse effect. In summer they absorb CO2 and it goes down. In winter it goes up. The big push upwards is us, burning fossil fuels.

The greenhouse effect, discovered by Joseph Fourier in 1824 and first investigated quantitatively by Svante Arrhenius in 1896, is the process in which the emission of infrared radiation by an atmosphere warms a planet's surface. In the case of the Earth, without these greenhouse gases its surface would be up to 30°C cooler. The name comes from an incorrect analogy with the way in which greenhouses are heated by the sun in order to facilitate plant growth. In addition to the Earth, Mars and especially Venus have greenhouse effects.

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

Might I suggest? The more scientific answers posted here might intimidate you or bore you, but I beg you to read them. Other simple answers based on analogies (like "trapping" heat) can lead you astray of the important fundamentals of global warming. During a debate, an uneducated person can *easily* be tricked or confused due to the nature of the global warming problem. What seems obvious often turns out to be bogus. Read up!

CO2 traps sun rays at earth and we all get hot.
