Romain Hugonnet, a research assistant and PhD student at the Laboratory of Space Geophysical and Oceanographic Studies (LEGOS), University of Toulouse, said a more accurate climate change indicator would be a measurement of the surface or volume of glaciers. However sea ice extent is growing in Antarctica [1]. Scientists are more interested in total glacial land coverage as a measure. The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Scientists collect detailed measurements to determine glacier mass balance, which is the net gain or loss of snow and ice over the course of the year. How many volcanoes have erupted in Iceland?

Despite their comparatively small area, glaciers contribute significantly to global sea level rise1. Citing a 2017 Arctic Monitoring and Assessment Programme study Colgan worked on, he said the world has lost about 33,000 gigatons of ice since 1948. According to the Randolph Glacier Inventory, "contains information for over 130,000 glaciers. If cumulative mass balance becomes more negative over time, it means glaciers are losing mass more quickly than they can accumulate new snow.

We dont know how many glaciers there were in 1948, Ben Marzeion, a climate scientist and professor at the University of Bremen, said. how many glaciers were there in 1950. The succession of Landsat satellites means that we can do repeated inventories, measuring glacier change at decadal scale resolution or better. It ensures that inventories carried out in different places by different people are comparable. These glaciers develop in high mountainous regions, often flowing out of icefields that span several peaks or even a mountain range. www.ipcc.ch/report/ar5/wg1. hydrology There "were definitely" more than 130,000 glaciers when Gore was born, he said they just werent well-counted.

Challenges and recommendations in mapping of glacier parameters from space: results of the 2008 Global Land Ice Measurements from Space (GLIMS) workshop, Boulder, Colorado, USA. Glaciers are very sensitive to changes in the atmosphere, so they're great indicators of climactic change. If glaciers lose more ice than they can accumulate through new snowfall, they ultimately add more water to the oceans, leading to a rise in sea level (see the Sea Level indicator). Computers & Geosciences 33, 104-125, (2007). Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water.
