Recent trends in arctic sea ice
Webb25 aug. 2012 · [2] As assessed from the modern satellite passive microwave data record that began in October 1978, Arctic sea ice extent exhibits downward linear trends in all months. The trend is largest for September (the end of the summer melt season), and appears to have steepened with time [ Stroeve et al., 2012 ]. WebbSince the mid-2000s, low minimum extents in the Arctic have become the “new normal.” Since 1979, the monthly September ice extent has declined 13.4 percent per decade relative to the average from 1981 to 2010.
