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.
How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas)
Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield.This energy (heat)is trapped insidethe car and cannotpass back throughthe windshield,causing the insideof the car to warmup.
What’s the differencebetween “global warming” and “climate change”?
DifferenceGLOBAL WARMING CLIMATE CHANGE is the increase of the is a broader term that Earth’s average refers to long-term surface temperature changes in climate, due to a build-up of including average greenhouse gases in temperature and the atmosphere. precipitation.

Simple 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.
Be Bulb Smart—Use CFLs What’s the Compact Incandescent difference? Fluorescent 500 lbs. of coal •1,430 lbs. CO2 pollution avoided •$30 saved
Simple 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 turningup the heat. Offer to help your parents keep the air filters on your AC and furnace clean.Walk short distances instead of asking for aride in the car. Plant a tree. Recycle.
