• Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere.

• Global Warming is the temperature rising each year.

How Global Warming Works

Fossil fuels (coal, oil, natural gas)

Carbon Dioxide (CO2)

Page 4: Global worminag ....daxa...310

Scientists say that the earth has warmed up about 1 degree F in the last 100 years.

GLOBAL

WARMING

is the increase of the Earth’s average

surface temperature due 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.

Page 7: Global worminag ....daxa...310

•Global Warming is caused by CO2 and other trace gases such as Methane given off by the burning fuels and wood.

• These gases called green house gases are mainly given off by factories and cars.

• Green house gases lets in heat, but doesn’t let the heat get out.

Habitat Damage and Species Affected

Changes in Water Supply

Increased Temperature

Rising Sea Level

Page 12: Global worminag ....daxa...310

• “Rising global temperatures are expected to raise sea level, and change precipitation and other local climate conditions.

• Changing regional climate could alter forests, crop yields, and water supplies.

• It could also affect human health, animals, and many types of ecosystems.

“Penguin population decline. Adelie penguin populations have shrunk by 33 percent during the past 25 years in response to declines in their winter sea ice habitat.”

The earth has had highs and lows, droughts and floods, but nothing has been like the past 150

years.

Reduce Global Warming

Refuse, Reuse, Recycle

Look for products without a lot of packaging. Use own

canvas bags for shopping instead of plastic or paper bags.

It takes energy to make a lot of packaging and to make

plastic and paper bags.

Reuse all items that are reusable. Reuse paper for

writing and solving math problems.

Reuse plastic and paper bags and some containers.

Recycled paper needs less power to manufacture than

making paper from trees. Also recycle bottles and cans.

We need to give trees more time to make paper.

Compact Fluorescent bulbs

Compact fluorescent light

bulbs use two-thirds less energy

than regular bulbs, so they save

energy.

This light bulb lasts much

longer – about five years -- and

gives off more light than the

incandescent bulb.

Turn Offand Disconnect

Electronics

Some even use electricity when they’re turned off but plugged in.

Turning off and

disconnecting

electronics

(television, computers,

etc.) when you aren’t

using them is

important to save

energy.

Page 19: Global worminag ....daxa...310

Save Electricity

Cover your water heater

with a blanket so that it

uses less electricity.

Start the dishwasher only

when it is full.

Take short showers

because they use less water.

Turn off the water when you’re not using it.

Plant Trees

Trees remove carbon dioxide from the atmosphere. They provide

oxygen for us to breathe and we provide carbon dioxide for them to

breathe. Plant trees next to houses and buildings to shade them and

use less air conditioning.
