A crash course in changing the world.
First, a digital poster of the discretionary budget of the US. The circles are scaled, so that the 600 billion dollar Dept. of Defense budget is visibly much bigger than the meager 6 billion dollar Dept. of Ed. budget.
Second, we have a site that uses computer generated climate models to look at future trends as well as our impact on future trends. As they say at the opening page:
In this chapter, users run the climate modeling software, Educational Global Climate Modeling Suite (EdGCM), to visualize how temperature and snow coverage might change over the next 100 years. They begin by running a "control" climate simulation to establish a baseline for comparison. After this first simulation, they run a second "experimental" simulation. Then they compare and contrast the changes in temperature and snow and ice coverage that could occur due to increased atmospheric greenhouse gases.
