NASA's Climate TimeMachine

NASA's Climate TimeMachine visualization shows the changes in annual Arctic Sea ice, sea surface height, carbon dioxide emissions, and global surface temperatures.

Arctic sea ice minimum is shown 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.

Sea surface height variations are shown, observed by the TOPEX/Poseidon and Jason-1 missions from January 1996 through December 2005.  These variations between what we see and what is normal for different times of year and regions are called anomalies, or residuals.

Annual carbon dioxide emissions produced by the top 12 nations or regions from 1980-2004 is graphically illustrated.  Units are given in thousand metric tons of carbon dioxide emitted from fossil fuel consumption. 

The progression of changing global surface temperatures from 1885 to 2007 are displayed an a color-coded map.  Dark blue indicates areas cooler than average.

Any one who thinks simulations can do climate are not engineers who have used simulations!...simply can not be used the way they are purporting to use them.
