What is the Greenhouse Effect?
• The greenhouse effect is a process in which the
absorption of infrared radiation by the
atmosphere warms the planet.
• The greenhouse effect was discovered by
Joseph Fourier.
• In case of Earth without greenhouse gases its
surface would be up to 30 degrees celsius
cooler.
Natural Causes
Global Warming is caused by many things. The causes split
into two groups, man-made and natural causes.
• Release of Methane gas from artic tundra and wetlands
• Methane, a greenhouse gas, traps and heats the Earth’s
atmosphere
• The other natural cause is the earth goes through a cycle of
climate change. This takes about 40,000 years.
Manmade causes
• Manmade causes do the most damage.
• Pollution is one of the biggest problems and it comes
in many shapes and sizes.
• Burning fossil fuels such as coal and oil cause
pollution.
• Fossil fuels give off the greenhouse gas CO2
• Another cause is population
• Population means more methane because more
transportation, burning fossil fuels and agricultural.

The warming is largely the result of emissions of carbon greenhouse gases from
human activities including industrial process and fossil fuel combustion
Greenhouse gas emissions will result in additional warming over the 21st century
There is an expected global increase of 2.5 to 10.4 degrees by 2100
This warming will have a real consequence for the United States and the world
Examples:
Sea levels will rise
Changes in perception patterns
Increase of droughts and floods
Threats to biodiversity
Number of potential challenges for public health
By the year 2050 one million additional deaths from malaria may be occur.
More Facts
• The natural and human systems are vulnerable to the
climate change because of their limited adaptive
capacity
• Yet this vulnerability varies with geographic location,
time, economic and environmental conditions
• We will all have to adapt to these climate change
consequences that aren't prevented by mitigation
• Economic losses can be expected more in poorest
regions because the higher the warming the greater
the loss

Buy fresh foods instead of frozen - Frozen food uses 10 times more energy to produce.
Eat less meat - Methane is the second most significant greenhouse gas and cows are one of the
greatest methane emitters.
Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever
possible.
Replace a regular incandescent light bulb with a compact fluorescent light bulb (CFL) - This simple
switch will save about 300 pounds of carbon dioxide a year.
Use less hot water- by installing a low flow showerhead (350 pounds of carbon dioxide would be saved
per year) and by washing your clothes in cold or warm water (500 pounds of carbon dioxide would be
saved per year)
Use a clothesline instead of a dryer whenever possible - You save 700 pounds of carbon dioxide when
you dry your clothes for 6 months out of the year.
Turn off electronic devices you're not using- simply turning off your electronic devices would save
thousands of pounds of carbon dioxide.
Plant a tree- a single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by
tree can also reduce your air condition bill.
Avoid chlorine at all cost. Use of any chlorine compounds is very harmful to the environment.
Move your thermostat down 2 degrees in the winter and 2 degrees in the summer- almost half of the
energy we use in our homes goes to heating and cooling. You could save 2,000 pounds of carbon
dioxide a year.
You can save $24 a year by leaving grass clippings on your lawn after you mow. This reduces the need
for fertilizing and watering your grass.
