Arrangement 7

2. What is Global Warming?
It is the gradual increase in the overall temperature of the earth's atmosphere (also known as Climate Change)
Human activity has increased the production of greenhouse gases in the atmosphere
In recent years global temperature has increased significantly
The warming of atmospheric temperature can have a drastic affect

3. Greenhouse Gases
They are emitted into the atmosphere due to natural processes such as…
Decomposition of Organic Compounds
Gas emitted from landfills
Common Types of Greenhouse Gases include
Carbon Dioxide
Methane
Nitrogen
Sulfur Dioxide
Methane Molecule
Carbon Dioxide Molecule
Nitrogen Molecule
All of these Gases contribute to the greenhouse effect...

4. Factories adding Carbon Dioxide into the atmosphere
EXAMPLES OF GREENHOUSE GASES ADDED TO THE ATMOSPHERE
Factories adding Carbon Dioxide into the atmosphere

5. Greenhouse Effect It is heat retention by greenhouse gases
Essentially, it keeps the earth's atmosphere warm
Too much heat retention can be detrimental to earth’s habitats

6. Habitats
Global Warming can affect many habitats in different parts of the world
A habitat is the environment in which a species normally lives or the location of a living organism
Global Warming can have a drastic effect on an arctic habitat
Arctic
Reefs
Rain Forest
The Sea

7. Consequence of Global Warming on The Arctic
Can affect many habitats in different parts of the world but it
A habitat is the environment in which a species normally lives or the location of a living organism
Can have a drastic effect it can have on arctic ecosystem
These effects include…
Glaciers and polar ice sheets melt
Creation of icebergs that eventually melt
Sea Level rises and low-lying areas become flooded
Risk of the Arctic ice cap completely disappearing
Polar Bears and other animals lose their ice habitat
Species of Arctic waters may become extinct
Alters food chain
Polar Bear
Melting Glacier

8. Annual Global Temperatures
Trends
the temperatures were relatively stable
the temperatures rose
1970- continues to rapidly rise
Hottest year on record 2014
An anamoly is the difference between the long-term average temperature (sometimes called a reference value) and the temperature that is actually occurring. In other words, the long-term average temperature is one that would be expected; the anomaly is the difference between what you would expect and what is happening.

9. Precautionary Principle
A principle that should be followed when possible consequences can have a drastic effect on society
It assumes the worst until proven false
Should be assumed when results could be catastrophic
Ex: Court of Law (pg. 45)
No proof for Global Warming
