Global Warming
A gradual increase in the temperature of the surface of
the Earth
![Page 3: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/3.jpg)
The Greenhouse Effect• The trapping of heat by
gases in the atmosphere• Raises the average
temperature of the Earth
Why is this needed for life to exist? It keeps the temperature warm enough for life to exist

Greenhouse GasesTrap heat
1. Carbon Dioxide burning fossil fuels such as coal, oil and natural gas
2. Methane- decomposing wastes in landfills
3. Nitrous Oxide- fertilizers 4. Water Vapor
An increase in greenhouse gases in the atmosphere is caused by burning of fossil
fuels.

WHAT ARE THE EFFECTS OF GLOBAL
WARMING?????
![Page 7: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/7.jpg)
1. Rising Sea Levels
• Caused by melting glaciers
• Flooding of coastal cites
![Page 8: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/8.jpg)
2. Extinction
• Species may not be able to adapt to change in climate
• Decrease in biodiversity
![Page 9: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/9.jpg)
3. Effect on plants and animals
• Possible migration to cooler areas
• Change in life cycles– Extend time for warmer climate plants
![Page 10: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/10.jpg)
4. Human Health
• Increased geographical area for tropical diseases- ideal conditions for many insects such as mosquitoes– Malaria, West Nile Virus, Dengue Fever– cholera
![Page 11: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/11.jpg)
5. Storms
• Warmer ocean water = more hurricanes
• Floods, loss of lives, damage to property
![Page 12: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/12.jpg)
6. Droughts• Crop failure
• Decrease in global food production- starvation
![Page 13: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/13.jpg)
7. Economy
• Cost of natural disasters
• Increase in food and energy costs
![Page 14: AIM: What is Global Warming? DN: Fill in the following chart: ProblemDefinitionCauseEffect Acid Rain Ozone Depletion.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697c00c1a28abf838cc8ace/html5/thumbnails/14.jpg)
8. Ecosystems
• Land, water, air
• Change in ecosystems can decrease the biodiversity- plants and animals may not be able to adapt
• Migration of animals- depletion of resources in certain ecosytems
