The mass of the Antarctic ice sheet has changed over the last several years. Research
based on observations from NASA’s twin NASA/German Aerospace Center’s twin Gravity
Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and
2016, Antarctica shed approximately 125 gigatons of ice per year, causing global
sea level to rise by 0.35 millimeters per year.
These images, created with GRACE data, show changes in Antarctic ice mass since 2002.
Orange and red shades indicate areas that lost ice mass, while light blue shades
indicate areas that gained ice mass. White indicates areas where there has been very
little or no change in ice mass since 2002. In general, areas near the center of
Antarctica experienced small amounts of positive or negative change, while the West
Antarctic Ice Sheet experienced a significant ice mass loss (dark red) over the fourteen-year
period. Floating ice shelves whose mass GRACE doesn't measure are colored gray.
What They Left Out
There is no perspective on this raw data, yet it is presented in a manner designed
for the general public.
Here is the perspective NASA left out:
125 gigatons is 125 cubic kilometers
There is a total of 26.5 MILLION cubic kilometers of ice in Antarctica.
Simple division (26,500,000/125) gives this:
There is 212,000 years of ice left at that rate!
(that is about two cycles of ice ages/warming)
They also forgot to tell us the history of the ice loss.
Was it faster or slower before man’s CO2?
Now that we know there is over 200,000 years of ice left, lets see how The Weather
channel reported this:
