How global warming works l.jpg

Carbon Dioxide (CO2)

Fossil fuels (coal, oil, natural gas)

How Global Warming Works


Slide4 l.jpg

Example of the Greenhouse Effect

The Sun’s energy passes through the car’s 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.



Difference l.jpg

GLOBAL WARMING “climate change”?

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.

Simple things to do l.jpg
Simple Things To Do “climate change”?

Turn off your computer or the TV

when you’re 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.

  • $30 saved


Simple things to do26 l.jpg
Simple Things To Do “climate change”?

Dress lightly when it’s hot instead of turning up

the air conditioning. Or use a fan.

Dress warmly when it’s 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.
