However, the 1980 eruption of Mount Saint Helens eliminated nine of its eleven named glaciers and only the new glacier known as Crater Glacier has been reestablished since. The succession of Landsat satellites means that we can do repeated inventories, measuring glacier change at decadal scale resolution or better. There are approximately 1000 glaciers in Glacier Bay National Park. Glaciers and ice caps (excluding the large Antarctic and Greenland ice sheets) respond quickly to climate change, and are likely to dominate eustatic (freshwater input from melting ice) contributions to sea level rise over the next few decades.

Figure 1 shows trends in mass balance for a set of 41reference glaciers around the world that have been measured consistently since the 1970s, including severalthat have been measured since the 1950s. The regions currently losing mass fastest are Arctic Canada North, Alaska, and glaciers around the periphery of the Greenland Ice Sheet. The southernmost named glacier among them is the Lilliput Glacier in Tulare County, east of the Central Valley of California. A glacier is a mass of ice so big that it flows under its own weight. Many others shared similar statements, including one Twitter user who suggests there are now 68,000 more glaciers in 2021 (here). Now that we have a complete dataset on global glacier outlines, we can use these data to understand glacier mass balance and potential contributions to sea level rise. Most of the outlines are from analyses of satellite imagery dating from 1999-2010.
