Greenhouse Effect - Natural Heating of Earth’s surface by certain atmospheric gases
Greenhouse Gases Water Vapor H 2 0 Carbon Dioxide C0 2 Methane CH 4
Without the Greenhouse Effect the Earth would be too cold for human life
Greenhouse Gases Carbon Dioxide Methane Nitrous Oxide CFCs Water Vapor
Without a Greenhouse Effect… Problem Solved? –Earth would be 33 degrees Celsius cooler
Global Warming -enhanced greenhouse effect resulting in a rise in global temperatures
Possible Results of continued Global Warming
Polar Ice Caps May Melt
Sea Level May Rise
Deserts Could Spread
Frequency and Severity of Storms may Increase
Scientist Discrepancy - some argue rising temperatures are due to natural cycles
Causes for increasing C0 2
Causes for increasing C0 2 Automobiles Burning Fossil Fuels Deforestation
How we can reduce our effects
How we can reduce our effects Conserve Energy Recycle Car Pool
Ozone Depletion - a thinning of the ozone layer
Ozone – O 3
Ozone – Blocks the harmful UV radiation from the sun
Ozone is made by chemical reactions involving UV light
Ozone Depletion is a major concern near the South Pole
Ozone Depletion is caused by increased levels of CFC’s in the atmosphere
“Ozone Hole” There is NO Hole It is a thinning of the ozone in the Polar Regions
The “Greenhouse Effect”

R21 Global Warming & Greenhouse Effect Prior Knowledge: What do you know about Greenhouse Effect and Global Warming?
Atmosphere Climate Ozone
Ozone & Greenhouse Effect. What is Ozone? Ozone is a molecule that occurs in the Stratosphere Ozone absorbs harmful UV rays from the sun O 3 + uv O 2.
Energy in the Atmosphere
Ozone depletion Ozone is O3.
The Greenhouse Effect. A lot of the light that comes from the sun, doesn’t make it to the surface of the earth.

May 10th, 2007 HW: Textbook- Read p , #’s 1-4 Do Now: Do you think that we need Earth to be warmed? Aim: What is the greenhouse effect and how.
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 Greenhouse Effect A large majority of the insolation that is radiated back into the atmosphere gets absorbed by greenhouse gases. A large majority.
