This series of visualizations shows how some of Earth's key climate indicators are changing over time.
This visualization shows the annual Arctic sea ice minimum since 1979. 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.
Recent satellite observations have detected that the Greenland and Antarctic ice sheets are losing ice. Even a partial loss of these ice sheets would cause a 1-meter (3-foot) rise. If lost completely, both ice sheets contain enough water to raise sea level by 66 meters (217 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.
This time series shows global changes in the concentration and distribution of carbon dioxide since 2002 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.
This color-coded map shows a progression of changing global surface temperatures since 1884. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.
