Global Glacier Change Bulletin 3 (WGMS) Reports Increasing Mass Balance Losses

Figure 1. Regionalized mean annual mass balance of WGMS reference glaciers 1980-2018, with 2019 being a mean of reference glaciers. Glaciers have been studied as sensitive indicators of climate for more than a century and are now experiencing a historically unprecedented decline (Zemp et al, 2015).  Glacier fluctuations in terminus position, mass balance and area are recognized as one of the most reliable indicators of climate change. This led to …

Global Glacier Change Bulletin-Many Glaciers Same Story

  Cumulative glacier mass balance losses reported by WGMS by region, all glacier, reference glaciers and geodetic mass balance (Sholes Glacier, WA in background).  The data set size, location and type changes but the story remains the same, mass loss resulting from global temperature increase. The World Glacier Monitoring Service has released the second bulletin of Global Glacier Change.  The bulletin provides detailed global and regional information on alpine glaciers …

World Glacier Monitoring Service 30th Anniversary

The numbers on the left y-axis depict quantities of glacial mass loss from the WGMS and sea level rise, and the suns across the horizon contain numbers that represent the global increase in temperature, coinciding with the timeline on the lower x-axis From Jill Pelto The World Glacier Monitoring Service (WGMS) celebrated 30 years of achievement last week. I have had the privilege of being the United States representative to the …

Alpine Glacier Mass Balance in 2015: Competes for Record Loss

  Painting from Jill Pelto illustrating the Climate Change Data using multiple quantities: the annual decrease in global glacier mass balance, global sea level rise, and global temperature increase. The numbers on the left y-axis depict quantities of glacial melt and sea level rise, and the suns across the horizon contain numbers that represent the global increase in temperature, coinciding with the timeline on the lower x-axis. The World Glacier Monitoring Service (WGMS) record …

Disastrous Year for North Cascade Glacier Mass Balance (Snow/Ice Economy)

  Mass loss of North Cascade glaciers visualized. A disastrous year is unfolding in 2015 for North Cascade glaciers, if normal melt conditions continue the range will lose 5-7% of its entire glacier volume in one year! For the 32nd consecutive year we were in the North Cascade Range, of Washington to observe the mass balance of glaciers across the entire mountain range. The melt season is not over, but …
