What is Global Warming?
Global Warming is the increase of Earth's average
surface temperature due to effect of greenhouse gases,
such as carbon dioxide emissions from burning fossil
fuels or from deforestation, which trap heat that would
otherwise escape from Earth. This is a type of
greenhouse effect.
• Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
• We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy.
What’s Causes Global Warming?
• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.
• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.
Global Warming Fast Facts
Every single day, 70 million tons of Carbon Dioxide are released into our world’s atmosphere. That’s 1.4 billion pounds – yesterday, today, tomorrow, and every single day.
The warmest years on record have been in the past 10 out of 12 years. Since record-keeping began in 1880, the planet’s 10 hottest years were all in your lifetime, between 1997 and 2008.(So yes, it probably did snow more when you were a kid.)
2008 saw the second-lowest summer Arctic sea ice ever recorded
since satellites began keeping track in 1979, at 1.74 million square
miles. This is 860,000 square miles below the average minimum seen
in the summers from 1979 to 2000. (Summer 2007 saw the lowest
levels ever recorded, at 1.65 million square miles).
Ships for the first time can sail along the Northwest Passage
above North America. Once a fabled passageway, melting Arctic ice
from global warming has let this route become a reality for the first
time in over 100 years.

For All You Non-Believers
Top 10 things YOU can do to help fight global warming:
1. Reduce, Reuse, and Recycle. ( The 3 R’s) 2. Use less heat and air conditioning. 3. Change a light bulb.4. Drive less, exercise more. 5. Buy energy efficient materials. 6. Use less hot water.7. Use the “off” switch.8. Plant a tree. 9. Find out how much energy your using
and use less. 10. Encourage others to change their
lifestyles too.
