Depending on the rate of global warming, 1/3 to 2/3 of the 56,000 #glaciers of the Himalaya, Hindu Kush, Karakoram & Pamir mountains will disappear by 2100 according to The Hindu Kush Himalaya Assessment (bit.ly/35hGAN8). Learn more from National Geographic: on.natgeo.com/2XwkvYx.

New photos vs old: a Reuters photo collection shows the dramatic retreat of Switzerland's glaciers. More than 500 Swiss #glaciers have vanished & experts believe 90% of the remaining 1,500 will go by the end of the century. See the photos here: reut.rs/2rtEBqf.

Mountain glaciers are important indicators of climate change and global warming. We can analyze trends by looking at the loss and gain of glacier mass, called MASS BALANCE. This can be thought of as the "Health" of the glacier. #twentymetersmelted

2017 is the 38th year in a row of negative glacial mass balance worldwide. This means that glaciers have been continually losing mass for 38 years. That makes for some "unhealthy" glaciers. #twentymetersmelted Lindsey, Rebecca. “Glacier Mass Balance.” climate.gov/news-features/….

Can you see the change? Glacier mass loss is real, and the melting is contributing to the rise in sea level. #twentymetersmelted climate.nasa.gov/climate_resour…

From 1980 to 2016 the cumulative mass balance loss from glaciers was -19.9 meters (20 meters melted). That is like removing a 72 foot thick slice off the top of an average glacier. #twentymetersmelted Lindsey, Rebecca. “Glacier Mass Balance.” climate.gov/news-features/….

Wolverine Glacier, South Cascade Glacier, and Gulkana Glacier have continually lost mass balance. Since 1965 South Cascade Glacier has lost 30 meters of water equivalent. epa.gov/climate-indica…

Time lapse photography can be used to visually analyze the recession of glaciers. Watch this LINKED VIDEO to see melting in action. youtube.com/watch?v=Za5wpC…

Over the past few decades, the average mass balance for glaciers around the world has been negative. This means they are continually decreasing in mass. “Latest Glacier Mass Balance Data.” World Glacier Monitoring Service, 10 Aug. 2019, wgms.ch/latest-glacier….

What is the measurement "Water Equivalent?" - It is the depth of water, spread out evenly over the glaciers surface, that would be lost or gained from the melting of ice. Scott and Lindsey. “2017 State of the Climate: Mountain Glaciers.” climate.gov/news-features/….

From 1980 to 2017, the 37 reference glaciers measured by WGMS cumulatively lost over 20 meter water equivalent. This follows the trend over continual mass loss. Michon and Lindsey. “2017 State of the Climate: Mountain Glaciers.” climate.gov/news-features/….

Climate change is directly connected to the melting of mountain glaciers and sea level rise. #twentymetersmelted

In 2017, of 29 reference glaciers surveyed, the overall loss of mass was equivalent to 1,036 millimeters of water equivalent. Lindsey, Rebecca. “Glacier Mass Balance.” NOAA Climate.gov, 1 Aug. 2018, climate.gov/news-features/…

Melting of mountain glaciers may have contributed up to 30% of sea level change in the 20th century, due to rapid ice volume reduction. “Global Glacier Recession .” National Snow and Ice Data Center, 2019, nsidc.org/glims/glacierm….

In 2017/2018 the mean annual mass balance of observed mountain glaciers was -1247 (mm w.e.). This is an increase from the mean of -877 in 2016/2017. “Latest Glacier Mass Balance Data.” World Glacier Monitoring Service, 10 Aug. 2019, wgms.ch/latest-glacier….
