State of Alpine Glaciers in 2016-Negative for 37th Consecutive Year

Figure 1. Global Alpine glacier annual mass balance record of reference glaciers submitted to the World Glacier Monitoring Service. Each year I write the section of the BAMS State of the Climate on Alpine Glaciers.  What follows is the initial draft of that with a couple of added images and an added paragraph. The World Glacier Monitoring Service (WGMS) record of mass balance and terminus behavior (WGMS, 2015) provides a …

2016 Field Season Results-North Cascade Glacier Climate Project

For Mount Baker, Washington the freezing level from January-April 20 was not as high as the record from 2015, but still was 400 m above the long term mean. April 1 snowpack at the key long term sites in the North Cascades was 8% above average. A warm spring altered this, with April being the warmest on record. The three-four weeks ahead of normal on June 10th, but three weeks …
