Description
“Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest. There are now nearly 700 maps. Maps 1-366 are also available as PDF posters. Use the menu above to find a map of interest. To learn a little more about this and other map projections read this: Worldmapper and map projections. We recently added a new series of maps of the world's population using a new mapping technique: Worldmapper Population Atlas.”

Americans’ Knowledge of Climate Change

Description
Americans’ Knowledge of Climate Change reports results from a national study of what Americans understand about how the climate system works, and the causes, impacts, and potential solutions to global warming. Among other findings, the study identifies a number of important gaps in public knowledge and common misconceptions about climate change.
Overall, we found that 63 percent of Americans believe that global warming is happening, but many do not understand why. In this assessment, only 8 percent of Americans have knowledge equivalent to an A or B, 40 percent would receive a C or D, and 52 percent would get an F. The study also found important gaps in knowledge and common misconceptions about climate change and the earth system. These misconceptions lead some people to doubt that global warming is happening or that human activities are a major contributor, to misunderstand the causes and therefore the solutions, and to be unaware of the risks. Thus many Americans lack some of the knowledge needed for informed decision-making in a democratic society. For example, only: 
  • 57% know that the greenhouse effect refers to gases in the atmosphere that trap heat;
  • 50% of Americans understand that global warming is caused mostly by human activities;
  • 45% understand that carbon dioxide traps heat from the Earth’s surface;
  • 25% have ever heard of coral bleaching or ocean acidification. 
Meanwhile, large majorities incorrectly think that the hole in the ozone layer and aerosol spray cans contribute to global warming, leading many to incorrectly conclude that banning aerosol spray cans or stopping rockets from punching holes in the ozone layer are viable solutions.”

Description
“The graph on the right side which always shows 400,000 years of temperature anomalies from modern times, derived from the Vostok Ice Core sample. As the three main elements of Earth orbit changes are enabled (see Checkboxes, below), a magenta-colored line plot is made which combines the simple sine ways of each element according to their periodicity. There is also a vertical slider on the left side of this graph which allows certain elements (again, see checkboxes below) to be changed to show their position or orientation back through the millennium.”

Why the Moon Changes Position Each Night
Suggested by
Pete Saracino
Description
“Have your students use their bodies!! One student will be the earth the other the moon. Have them face each other, then have the "earth" go thru a complete rotation. While the "earth" is going through a rotation, have the "moon" continue its orbit part way round the "earth". When the "earth" returns to the spot where it last saw the moon it will no longer see the moon where it was before because the moon has moved on a bit in its own orbit.  The "earth" will have to rotate a bit more to once again be able to see the "moon".....about 50 minutes later each day.
