1. Volcanic Eruptions- temporary cooling2. Weather Activity- El Nino & La Nina3. Solar activity- Sunspots = extra heat4. Earth’s Motions- Distance from the

What is the difference between global warming & green house effect?

Greenhouse effect causes global warming. Global warming also concentrates on CO2, while greenhouse effect on all 5 gases.

To produce many of your common goods—computers, sneakers, water bottles, food—we burn fossil fuels.

Fossil fuels are energy sources made from the remains of dead plants and animals. The most commonly used fossil fuels are coal, oil/petroleum, and natural gas.

Burning these fossil fuels to make household products produces CO2 and this CO2 is

released into the atmosphere.

In the atmosphere this CO2 joins the other greenhouse gases. These greenhouse gases

include things like methane, nitrous oxide, and water vapor.

These gases are necessary because they act as a blanket and keep our planet warm.

However, when large amounts of CO2 enter the atmosphere it causes this layer to get

thicker.

Think about it…In the summer, why does the inside of a car get very hot when it is sitting in the sun?

11

The heat from the sun goes into the car. The windows on the car trap the heat inside. This makes the inside of the car heat up

Think back to our car? What happens if the windows get thicker?

As CO2 is added to the greenhouse gas layer, it becomes thicker. As it becomes thicker, it traps in

more of the Sun’s rays. And, just like your car, causes the earth to heat up!

CCOMMON PITFALLS

The ozone layer is created by global warming!

NO! It is formed by the release of carbon gases, not by the increase in temperature…

Greenhouse gases are a bad thing…

Only when there are too many!

5 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.
