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.

Exhaust from cars Major source of Carbon dioxide in the

atmosphere

A 12 miles per gallon vehicle in the city

will emit an estimated 800 pounds of

carbon dioxide over a distance of 500

city miles

Exhaust from airplanes

Aviation industry causes 3.5 percent of

global temperature Could rise to 15 percent by 2050

Carbon dioxide from constructions

Building structures account for about

12% of carbon dioxide emissions.


5/28

Deforestation

Causes about 20-25% of all carbon emissions entering theatmosphere

About 34 million acres of trees are lost each year

Millions of acres of rainforests are lost every year, equivalent in

area to the size of Italy

How Global Warming Works

Fossil fuels (coal, oil, natural gas)

Carbon Dioxide (CO2

)

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

Whats the difference

between global warmingand climate change?


9/28

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.

What can you do to help

solve the problem?

Simple Things To Do

Turn off your computer or the TV

when youre not using it.

Take shorter showers. Heating water uses energy.

Keep rooms cool by closing the blinds, shades, or

curtains.

Turn off the lights when you leave a room.

Use compact fluorescent bulbs.

Simple Things To Do

Dress lightly when its hot instead of turning up

the air conditioning. Or use a fan.

Dress warmly when its cold instead of turning

up the heat.

Offer to help your parents keep the air filters on

your AC and furnace clean.

Walk short distances instead of asking for a

ride in the car.

Plant a tree. Recycle.
