(08.03, 08.04, 08.05 HC) Since the early 20th century, glaciers around the world have been retreating at unprecedented rates. Scientists have studied 37 glaciers since 1980 to collect data on their average mass in the graph below: © Climate.gov—NOAA   Refer to the graph in figure 1 to answer the following questions. Describe the trend of glacier ice loss and gain between 1990 and 2014. Describe a positive feedback mechanism affecting the rate of glacier retreat. Explain two effects of melting glaciers and sea ice have on land and sea environments. In northeast Greenland, a glacier named Zachariae Isstrom entered a phase of accelerated retreat in 2012. Over the last few years, the glacier has broken up and is now fracturing, with large icebergs being released into the ocean. Describe two threats affecting the biodiversity of polar and glacier ecosystems. Propose a solution to reduce the impact of melting glaciers on Earth’s biodiversity. Justify how this solution would protect marine or land species from extinction.
