Scientists Confirm Earth's Energy Is Out of Balance
Back in 2005 scientists confirmed that the earth's energy input and output were out of balance. Here's a new link to an article about the energy balance of our planet earth. There is also an animation of the heat flow from the sun to earth and the effect of different kinds of clouds in reflecting or transmitting radiation. http://www.nasa.gov/vision/earth/environment/earth_energy.html

Here are some links to games related to this topic (you need macromedia flash installed for these to work). **Warm up the Cat!** [|Heat Radiation experiment] **Bounce the light beam!** [|Shadow Formation experiment]
