What’s this got to do with global warming?

Light and heat energy from the

Sun

Most of this is reflected back

into Space

Only a small amount is absorbed and warms the Earth’s

surface

Healthy Planet

What is Global Warming?

Earth’s Atmosphere

Not so healthy planet

Greenhouse Gases

Only a small amount is reflected back

into Space

A lot more is trapped by the

gases and absorbed. The

temperature of the Earth’s surface

increases.
