TRANSCRIPT
• 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)
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.
•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.
Pollution from
coal, natural
gas, and oil
Habitat Damage and Species Affected
Changes in Water Supply
Increased Temperature
Rising Sea Level
• “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.
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.
