Global Tempratures Time Machine: press here

This color-coded map shows a progression of changing global surface temperatures from 1884 to 2015. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

Carbon Dioxide Time Machine: press here

This time series shows global changes in the concentration and distribution of carbon dioxide from 2002-2014 at an altitude range of 1.9 to 8 miles.  The yellow-to-red regions indicate higher concentrations of CO2, while blue-to-green areas indicate lower concentrations, measured in parts per million.

Sea Level Time Machine: press here

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).  Land that would be covered in water is shaded red.

Sea ice Time Machine: press here

This visualization shows the annual Arctic sea ice minimum from 1979 to 2015.  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.
