Warm UpName the 4 natural causes of global warming?
1. 2. 3. 4.
THEN explain how each adds to global warming
What is the difference between global warming & green house effect?
Do NowName the 4 natural causes of global warming?
1. Volcanic Eruptions- temporary cooling2. Weather Activity- El Nino & La Nina3. Solar activity- Sunspots = extra heat4. Earth’s Motions- Distance from the
sun/Removes River basins
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.

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?

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
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!

CONCLUSION: As CO2 levels increase, temperature levels increase

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!
Urban Heat Islands
How is heat affecting the daytime & nighttime differently in cities? How does “cooling roofing” help improve global warming? Why do more people use
it as a strategy? Why are plants helpful in reducing global warming? (Hint: two processes plants do) What is Charlotte NC specifically doing to help relieve global warming effects?http://www.youtube.com/watch?v=t-sXHl3l-rM
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.
• What’s our class’s average Carbon Footprint and what does this mean?

• Why does it take so many Earth’s to support our way of life?
• Okay, so how does that play out around the world??
