Rising sea levels

FILE - This early Friday, Aug. 16, 2019 file photo shows an aerial view of large Icebergs floating as the sun rises near Kulusuk, Greenland. Greenland has been melting faster in the last decade, and this summer, it has seen two of the biggest melts on record since 2012. A special United Nations-affiliated oceans and ice report released on Wednesday, Sept. 24, 2019 projects three feet of rising seas by the end of the century, much fewer fish, weakening ocean currents, even less snow and ice, and nastier hurricanes, caused by climate change.
