Likewise, the earth’s atmospheric gases affect the ability of the earth to radiate the Sun’s energy back into space. Nitrogen, Oxygen and Argon make up >99% of the earth’s atmospheric gases and are non-greenhouse gases. Water, Carbon Dioxide, and Methane make up <1% of the earth’s atmosphere, but are greenhouse gases, since they cause the earth to retain heat.

GLOBAL WARMING is the increase of the Earth’saverage surface temperature dueto a build-up of greenhouse gases in the atmosphere. TEMP. INCRESES
Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
What’s the d ifference between “global warm ing” and “clim ate change”? GLOBAL WARMING CLIMATE CHANGE It is the increase of It is a broader term the Earth’s average that refers to long- surface term changes in climate, including temperature due to average a build-up of temperature and greenhouse gases precipitation. in the atmosphere.
