Presentation on theme: "Warm Up Name the 4 natural causes of global warming?"— Presentation transcript:
1 Warm Up Name the 4 natural causes of global warming? THEN explain how each adds to global warmingWhat is the difference between global warming & green house effect?
2 Do Now Name the 4 natural causes of global warming? Volcanic Eruptions- temporary coolingWeather Activity- El Nino & La NinaSolar activity- Sunspots = extra heatEarth’s Motions- Distance from the sun/Removes River basinsWhat 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.

5 To produce many of your common goods—computers, sneakers, water bottles, food—we burn fossil fuels. 5
6 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.6
7 Burning these fossil fuels to make household products produces CO2 and this CO2 is released into the atmosphere.CO2CO2CO2CO2CO2CO27
8 In the atmosphere this CO2 joins the other greenhouse gases In the atmosphere this CO2 joins the other greenhouse gases. These greenhouse gases include things like methane, nitrous oxide, and water vapor.methaneNitrous oxidewater vaporCO2CO2CO2CO2CO2CO28
9 These gases are necessary because they act as a blanket and keep our planet warm. CO2CO2CO2CO2CO2CO2methaneNitrous oxidewater vapor9
10 However, when large amounts of CO2 enter the atmosphere it causes this layer to get thicker.CO2CO2CO2CO2CO2CO2methaneNitrous oxidewater vapor10
11 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
12 Think back to our car? What happens if the windows get thicker? 12
13 As CO2 is added to the greenhouse gas layer, it becomes 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!methaneNitrous oxidewater vaporCO2CO2CO2CO2CO2CO213
14 CONCLUSION: As CO2 levels increase, temperature levels increase methaneNitrous oxidewater vaporCO2CO2CO2CO2CO2CO214
15 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!
16 FAST FACT!The human population of the world is expected to be nearly tripled by the year 2100
17 Urban Heat IslandsHow 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?
18 What’s being done now to reduce our emissions? Wind PowerSolar PowerFuel-Efficiency
19 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, orcurtains.Turn off the lights when you leave a room.Use compact fluorescent bulbs.
20 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??
