__The Evidence of Humans Impacting the Warming of the Planet__ "Human impacts on the climate system include increasing concentrations of atmospheric [|greenhouse] gases, air pollution, increasing concentrations of airborne particles, and land alteration." The following are examples of how humans effect climate change:
 * The increase of greenhouse gases are due to human activities.
 * It is **very likely** that, overall, human activities since 1750 have had a global warming effect on the Earth.
 * Regions of the world with many physical and biological changes are showing the highest amount of warming.
 * Model projections have linked the changes in some physical and biological systems to the warming induced by human activities.
 * The principal anthropogenic greenhouse gas is carbon dioxide (CO2),whose concentration has increased by 31% since 1750 to a level which is likely to have not been exceeded for 20 million years. This increase is predominantly due to fossil fuel, but also to land-use change, especially deforestation.
 * 69 percent of Americans now believe that global warming is caused mainly by human activities and this is a very high amount of Americans, so why don't you be like everyone else and believe that global warming is caused by humans.

__Human Activities That Harm the Planet__ []
 * 1) Burning of Fossil Fuels
 * 2) Deforestation
 * 3) Driving non-hybrid vehicles
 * 4) Air Pollution
 * 5) Water Pollution
 * 6) Changing the land in any way.
 * 7) Agriculture



__True Facts About Global Climate Change__ []
 * Antarctic ice is 5% above average.
 * Arctic ice is 13% below average.
 * Global sea ice is at 5% below average.
 * US temps 2009: 0.2° C above 100+ year average, October 2010 was above average.
 * 2009 Global Results: +0.56° C anomaly; 5th warmest since 1890.
 * CO2 rises to 0.000388.
 * Sea level is rising 3.2 mm/year.

__My Thoughts on Global Climate Change__ This issue matters to me because I want to live in a world where people actually care about the Earth and would like to make changes to this world that can better everything. If factories would realize they have to cut down on all air pollution and if cars that are environmentally friendly were priced more reasonably, people would be able to afford to buy them and this would highly cut the amount of greenhouse emissions. If people want to live their life and want generations after them to live on this beautiful planet, then changes will have to be made to make the world a cleaner and better place.
