Average cumulative mass balance of "reference" Glaciers worldwide from 1945-2014 sourced from [US EPA][datahome] and the [World Glacier Monitoring Service (WGMS)][wgms].
This is cumulative change in mass balance of a set of "reference" glaciers worldwide beginning in 1945. The values represents the average of all the glaciers that were measured. Negative values indicate a net loss of ice and snow compared with the base year of 1945. For consistency, measurements are in meters of water equivalent, which represent changes in the average thickness of a glacier.

## Useful info
There does seem to be more recent data because there are graphs with more recent e.g. [graphs like this on Climate.gov](https://www.climate.gov/news-features/understanding-climate/2012-state-climate-glaciers), or [PDF data like this from World Glacier monitoring service](http://wgms.ch/products_fog/) and this [PDF from WGMS](http://wgms.ch/downloads/wgms_2012_fogX.pdf).
* Data from World Glacier Monitoring Service (WGMS): http://wgms.ch/data_databaseversions/
Here is zip file with datasets: http://wgms.ch/downloads/DOI-WGMS-FoG-2015-11.zip
Internationally collected, standardized dataset on changes in glaciers (length, area, volume, mass), based on in-situ and remotely sensed observations, as well as on reconstructions.
* [GLIMS Glacier database](http://www.glims.org). From the site: "GLIMS (Global Land Ice Measurements from Space) is a project designed to monitor the world's glaciers primarily using data from optical satellite instruments, such as ASTER (Advanced Spaceborne Thermal Emission and reflection Radiometer)." Data can be found at http://glims.colorado.edu/glacierdata/ which links to http://www.glims.org/download/. Data is large tgz files - probably containing geodata on individual glacier outlines. Stats on data contents at http://glims.colorado.edu/glacierdata/db_summary_stats.php - these show coverage from 1870 to 2011 and thousands of glaciers worldwide.
* Relationship to WGMS World Glacier Inventory: "The GLIMS database is designed to be a logical extension of the World Glacier Inventory (WGI) of the World Glacier Monitoring Service (WGMS) and stores the full complement of the WGMS-defined glacier characteristics." [source](https://nsidc.org/glims/)
* The US EPA also have this [Graph: Average cumulative mass balance of "reference" Glaciers worldwide from 1945-2014](http://www3.epa.gov/climatechange/science/indicators/snow-ice/glaciers.html). You can get the CSV Data for the graph here: http://www3.epa.gov/climatechange/images/indicator_downloads/glaciers_fig-1.csv. According to the footnote for the graph the original source is:
