Rising temperatures have caused the amount of Arctic sea ice to shrink dramatically since global observations began in the 1970s. But on the other side of the world, sea ice in Antarctica was at first steady — and then began to slowly expand in the mid-2000s. Some researchers now say that the Antarctic trend may have been inflated by an error in the decades-long record of satellite observations of Southern Hemisphere sea ice. Scientists process data from microwave-sensing satellites using one of two standard algorithms to distinguish bright sea ice from dark open water. scientificamerican/article/error-discovered-in-antarctic-sea-ice-record/
