How Global Warming Works?
Fossil fuels (coal, oil, natural gas)
Carbon Dioxide (CO2)
![Page 4: Global warming](https://reader033.fdocuments.net/reader033/viewer/2022060109/55541899b4c905987e8b4a57/html5/thumbnails/4.jpg)
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.
Example of the Greenhouse Effect

DifferenceDifferenceGLOBAL 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.

An increase in global temperature will cause sea levels to rise and will change the
amount and pattern of precipitation. Warming is expected to be
strongest in the Arctic and would be associated with continuing
retreat of glaciers.Other likely effects of the warming include more frequent occurrence of
extreme weather events including heatwaves, droughts and heavy rainfall
events, species extinctions due to shifting temperature regimes, and changes in
agricultural yields.

Simple Things To DoSimple Things To Do
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.
![Page 34: Global warming](https://reader033.fdocuments.net/reader033/viewer/2022060109/55541899b4c905987e8b4a57/html5/thumbnails/34.jpg)
Simple Things To DoSimple Things To Do
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.
Keep the air filters on your Air Conditioner and
furnace clean.
Walk short distances instead of asking for a ride in the car.
Plant a tree. Recycle.
