Climate Time Machine

 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.

Above is the perennial ice cover from this past year of 2020. Was there a significant loss or gain in the ice since 1979?

Gain

Why do you think that there was a significant loss or gain in the ice cover?

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.

Now Click On Carbon Dioxide (3rd picture at the top)

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.
