What is global warming? The changes in the surface air temperature, referred to as the global temperature, brought about by the enhanced greenhouse effect, which is induced by emissions of greenhouse gases into the air.

How Global Warming Works Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )

GLOBAL WARMING is the increase of the Earths average surface temperature due to a build-up of greenhouse gases in the atmosphere.

The Suns energy passes through the cars 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. Example of the Greenhouse Effect
