Are you searching for interactive graphics for use in science class to show your students the current and expected effects of global warming?
The Climate Time Machine by the Jet Propulsion Laboratory (JPL) and California Institute of Technology (CIT) of NASA provides the graphics you need.
These graphics are also excellent for displaying on an interactive white board (IWB) to allow you and your students to interact with the data provided by the graphics representing climate change .
Climate Change
The Climate Time Machine provides information in the following four categories:
Sea Level: recent satellite observations have detected a thinning of parts of the Greenland ice sheet at lower elevations. A partial melting of this ice sheet would cause a 1-meter (3-foot) rise. If melted completely, the Greenland ice sheet contains enough water to raise sea level by 5-7 meters (16-23 feet). This visualization shows the effect on coastal regions for each meter of sea level rise, up to 6 meters (19.7 feet).
Sea Ice: this visualization shows the annual Arctic sea ice minimum from 1979 to 2007. At the end of each summer, the sea ice cover reaches its minimum extent, leaving what is called the perennial ice cover. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979.
CO2 Emissions: this visualization shows the amount of annual carbon dioxide emissions produced by the top 12 nations or regions from 1980-2004.
Average Global Temperature: this color-coded map shows a progression of changing global surface temperatures from 1885 to 2007.
