Global Warming – What is it?
Rise in earth’s temperature
Results from changes in the natural environment 
Caused by too much carbon dioxide

The Greenhouse Effect
Solar radiation from the Sun reaches the Earth’s atmosphere
The surface of the Earth absorbs most of the short-rayed insolation and later releases this heat in the form of infrared radiation into the atmosphere.
Some of the heat is absorbed by particles known as “greenhouse gases.”
The heat retained by the gases acts as a “heat blanket.”

Burning of fossil fuels
The burning of fossil fuels releases Carbon dioxide in the atmosphere.                  

 In the past 150 years, burning fossil fuels has caused a 25 % increase in Carbon dioxide emissions.

The Ties Between Sardines &  Global Warming
The over-hunting of sardines has caused higher levels of phytoplankton in the ocean.
While living, phytoplankton release oxygen into the atmosphere and use Carbon for photosynthesis
 When they die, their decay releases large amounts of methane and the poisonous gas, hydrogen sulfide.  It also uses large amounts of oxygen.

Sardines & Global Warming (Cont.)
Methane is 21 times more effective  than carbon dioxide in maintaining heat in the atmosphere. 
This results in the deaths of numerous marine animals.

Effects of global warming
More carbon dioxide  ->    increase in plant growth.
The increase in temperature  -> rise in sea level from melting glaciers and polar ice caps   (adds 0.2 mm annually)
Rising temperatures will also cause drier conditions in many important agricultural regions.

GLOBAL WARMING:
Sea Life
GLOBAL WARMING’S NEGATIVE IMPACT ON SEA LIFE—
Coral Reef Bleaching— 
Change in temperature and elevated sea level cause loss of algae in the coral. 
Coral appears white, or “bleached.”  
Result is mass death of sea animals, which are dependent on the coral reef.
 The penguin population near Antarctica has been declining as the distance between them and their food has increased.

Rising Sea levels
The rise of temperature, even to a few degrees, could lead to the melting of ice shelves that hold back glaciers. This results in rising sea levels
The Larsen area of North Antarctic, South of Chili and Argentina have lost more than 5,200 sq miles of area.

The Effects of Global Warming on Land animals
Global warming can disrupt the migration, hibernation and reproductive cycles of certain types of animals. 
Plants and animals will find it hard to escape or adjust to the effects of warming because humans occupy so much land.
Farmland or cities interrupt the movement of species between habitats.

Health & Global Warming
Extreme temperatures can directly cause the loss of life (ex: 35,000 people died during heat wave in Europe, Aug‘03.)
Warmer weather provides an ideal breeding environment for mosquitoes. Diseases such as West Nile will be more common.

IMPACT ON AIR
The atmosphere’s ultimate fate is unclear. 
		More evaporation  increase in cloud cover

How High Will the Clouds Be?  It makes a difference!
Clouds close to the earth reflect sunlight   cooling effect. 
Clouds high in the atmosphere trap heat  warmingeffect. 

 Generally:
Cloud cover increases 
Levels of the greenhouse gas methane may increase 
Hurricanes range farther north, south on warmer water

El Niño Effect          
Severe oceanic/atmospheric disturbance,  
     every 7-14 yrs (“the child”)
Warm surface waters suppress cold, nutrient-rich upwelling of the Humboldt Current 
 Fall in the number of plankton
Wreaks havoc upon the entire ocean food chain
Devastates the fishing industry

The Climate Stewardship Act
First introduced in the senate in 2003 and  reintroduced in February 2005
It would reduce carbon dioxide, methane, nitrous oxide, hydroflurocarbon and perfuorocarbons which are released by power plants to 2000 levels by 2010.
The bill reduces the risk of global warming without hurting the economy.

How To Prevent 
Global Warming:
Plant trees
Conserve energy:
	(examples: 1. use low-energy, low-water-use washing machines, 2. use a solar heated system for hot water, 3. use an electric or push mower for gasoline powered mower) 
Buy energy efficient products
Buy products that have reusable or recyclable packaging
Reduce use of car (walk instead)
