NASA's Remote Sensing Tutorial: If you have heard the term "remote sensing" before you may have asked, "what does it mean?" It's a rather simple, familiar activity that we all do as a matter of daily life, but that gets complicated when we increase the scale. As you view the screen of your computer monitor, you are actively engaged in remote sensing.

This Tutorial will help you have a better understanding for Remote Sensing. Click here to download information and learn more about Remote Sensing from NASA.

Tropical Deforestation Fact Sheet: The clearing of tropical forests across the Earth has been occurring on a large scale basis for many centuries. This process, known as deforestation, involves the cutting down, burning, and damaging of forests.

This fact sheet, a modified version from the Earth Observatory one, explains why Deforestation Happens. Click here to learn about the Rate of Deforestation, Deforestation and the Global Process, and After Deforestation

The Mystery of the Missing Carbon: Scientists estimate that between 1 and 2 billion metric tons of carbon per year are "missing" from the global carbon budget. Or, more precisely, they cannot account for the location of between 15 and 30 percent of the carbon released into the atmosphere each year from fossil fuel burning (Sellers et al. 1997).

The article which is modified from the Earth Observatory one explains where all the carbon is going. Click here to view it.
