Global warming occurs when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot adopt to a radically new environmental change, so they die. We are losing thousands of species every day due to global warming. It's an established scientific fact that humans are largely responsible for Global Warming. Here are some main culprits:
- GREENHOUSE GAS EMISSIONS
Problems:
Increasing atmospheric concentrations of greenhouse gases that result in CO2 emissions caused by burning fossil fuels (mainly coal and petroleum ) in power plants, automobiles, airplanes, improper building structures etc. In the U.S. alone, more than 90% of Some other examples of using energy and polluting the air are:
Solutions:
Ride bikes to work/school as much as possible
Drive cars with high MPG (eliminating SUV usage) such hybrid cars
Planning even the small trips to use gas more effectively
Using big trucks ONLY for farm / industry usage
Buying local produce to decrease the gas mileage on such products
- DEFORESTATION
Problems:
Humans are cutting trees at an alarming rate and using earth's resources in an improper manner to produce high $ crops over and over, which does not allow earth to regenerate its strength.
Solutions:
Plant trees in your backyard, neighborhood, city. Be more involved with local environmental organizations to take simple steps to make our planet greener. Speak Up against the big corporations profit at the cost of killing thousands of living species everyday and endangering our future.
- ENERGY WASTE
Problems
We can prevent energy waste simply by changing the way we do the things mentioned below:
Turning on a light
Watching T.V.
Listening to a stereo
Washing or drying clothes
Using a hair dryer
Riding in a car
Heating a meal in the microwave
Using an air conditioner
Playing a video game
Using a dish washer
Solutions:
Use everything mentioned above LESS

Yes people are definitely causng global warming if you know what i mean. We are actually an assist to global warming. When i was little i thought it was called global warning to warn you of the global but when i found out it was called global warming i knew why i thought both: Global warning: *Warns you of the global Global warming: *warns the earth and melts the ice in greenland And we dont controll the planets, they controll themselves.

Here is a link to a flow chart of human sources.
http://cait.wri.org/figures.php?page=World-FlowChart&view=100
The major factors are:
Anthropogenic.
Positive RF sources. (Sources that warm the Earth)
CO2 +1.66 W/m2.
CH4 +0.48 W/m2.
N2O +0.16 W/m2.
Halocarbons +0.337 W/m2.
Tropospheric Ozone +0.35 W/m2.
Black carbon on snow + 0.10 W/m2.
Linear contrails + 0.010 W/m2.
Negative RF sources. ( sources that cool the Earth)
Land use - 0.20 W/m2.
Aerosols (direct and cloud effect) - 0.50, - 0.70 W/m2.
Natural.
Positive RF sources
Solar irridiance + 0.12 W/m2.
Negative RF sources.
Volcanic Aerosol emissions: -
The combined anthropogenic RF is +1.6 [ -1.0, +0.8] W/m2.
The combined natural RF ( solar irridiance, volcanic aerosols) is + 0.12 [-0.06, +0.18].
* RF is defined as the change in net irridiance at the Tropopause (boundary between Troposphere and Stratosphere).
All measurements are showing the difference in RF between 1750 (preindustrial), and current (2005).
Radiative forcing is a measurement of how strong the factors that influence Earths climate by altering its energy balance are. A positive forcing increase the energy which will lead to a warming while a negative forcing reduces the energy and leads to a cooling.

Anthropogenic factors:
Greenhouse gases:
CO2 from fossil fuels
CH4 from many sources fossil and contemporary
N2O from nitrogen fertilization and agriculture
CFCs and their replacements
Land use changes, primarily deforestation

The largest factor of global warming is carbon dioxide that's released from volcanic activity! People and their pollutants are not NEAR as influencing to global warming!

radiation from the sun
greenhouse gases which hold heat in the atmosphere
earth surface covering (dark colored surfaces absorb solar radiation, light colored surfaces like snow reflect solar radiation)
life (including, but not limited to human life), which converts carbon from the earth to CO2, O2, methane, and other atmospheric gases
volcanic activity which spews gases into the atmosphere
many others factors too numerable and complicated to discuss here

The answer to that question is beyond yahoo answers. I am sure it would take a PHD a life time to answer this one.
