Become a student yourself...
How much science you need to get into, again, also depends upon you, but I like to bring up the difference between science and common sense. People often rely on common sense - if there are record snow storms in 10 cities in one part of the country, then some will think that common sense says that there is no global warming. Unfortunately common sense is often wrong. It was common sense that the earth was flat, that the sun moved around the earth, that people couldn't affect the earth's climate. Science is the best way to test common sense. Look at the kind of information that scientists look at with satellite images and map information. Some of these are just NASA images but some are websites that students should be able to learn how to navigate.

In the end, scientists try to determine global warming by creating computer models - lots of mathematics and billions of pieces of data - and most people will never be able to get a real feel for how scientists try to "prove" global warming, but the above website can give you an idea of what scientists look at...
