global pollution

Global pollution is that which is emitted locally but yet has global effects, such as rising sea levels, climate change, and a significant impact on the coastal environment and communitities. The question stands of who is to blame for such effects? The majority of the problems experienced are due to the greenhouse effect and the release of carbon dioxide and carbon monoxide in the air. Over 25% of CO2 emissions come from transportation and over 25% come from domestic energy use. The primary causes are the burning of fossil fuels such as coal, oil, and gas or through deforestation, which includes wild fires and the aftermath of El Nino.

With resources such as NASA's Visible Earth, countless number of satellites images can be used to analyze the harmful effects and target their points of origins as well as the regions.
Some examples of some images are included below. Other studies on their website include:
- A NASA tera satellite was used to track global pollution in a study performed several years ago.
- An animation shows Global Carbon Monoxide and Global Sea Surfact Temperature
