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 (CO2

)


5/29

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.

Greenhouse Effect

Difference

GLOBAL WARMING

is the increase of the

Earths average

surface temperaturedue to a build-up of

greenhouse gases in

the atmosphere.

CLIMATE CHANGE

is a broader term that

refers to long-term

changes in climate,including average

temperature and

precipitation.
