During late February, Antarctic sea ice breached the previous all-time record low for extent coverage since measurements began in 1978. And in the following days, sea ice extent measures near the South Pole have continued to creep lower, gradually extending into unprecedented ranges.
Record Melt During a Period of Considerable Global Heat

Hitherto unseen global heat — driven primarily by human fossil fuel emissions — appears to be the chief contributor to this melting. During 2016, global average surface temperatures rose to 1.2 degrees Celsius above 1880s ranges. This global reading likely represents the warmest surface temperatures the world has experienced in the last 115,000 years. At the same time, the global ocean system has been rapidly accumulating warmth and transferring it through the surface and deep…
