INTRODUCTION
WHAT IS IT ?
GLOBAL WARMING
It is the increase in the average temperature Of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.
HISTORY OF GLOBAL WARMING
Svante Arrhenius (1859-1927)
Fossil fuel combustion
Twice(carbon dioxide)=a 5oC temperature rise

CAUSES OF GLOBAL WARMING
Natural Causes
---created by nature
---release of methane gas from arctic tundra and wetlands
---the earth goes through a cycle of climate change.
---This climate change usually lasts about 40,000 years.

Man made causes
---most damage
Pollution
-Burning fossil fuels –mining
2) Population
3)Green house effect

Effects of global warming
On birds and animals
On human health
Agriculture
Sea level rise
Weather




Predicted Effects and Impacts 
More Floods
Increased spread of infectious diseases
Degraded water quality
Degraded water quality
predictions of global warming
global mean temperature - increase by
1.4 and 5.8 C
the Northern Hemisphere cover – decrease &the Antarctic ice sheet increase.
the sea level rise by between 9 and 88 cm
increase in some extreme weather events
Facts of global warming
Average temperatures have climbed 0.8 C around the world since 1880
The Arctic is feeling the effects the most.
The global warming we are experiencing is not natural. HUMANS are causing it.
NEW TREND-warmer winters.
Global warming and the ozone hole are two different problems.

Steps to prevent
Drive less.
Use hybrid or electric vehicle
Light bulbs -->energy-efficient fluorescents
Cut down on your garbage
Unplug electronics when they are not in use
Buy recycled paper products
Plant a tree.
