GCW held its first Tropical Cryosphere Workshop in Arusha, Tanzania, 4-6 July 2017. Participants were from Tanzania, Kenya, the Democratic Republic of the Congo, Morocco, Indonesia, Ecuador, Peru, Bolivia, Austria, Iceland, Switzerland, and the United States. Some information has been posted on the meeting page (http://globalcryospherewatch.org/meetings/arusha2017/); more will be posted in the coming weeks.

Look at some exclusive satellite imagery of the July 2017 Larsen C iceberg in the Interesting Events section (http://globalcryospherewatch.org/interesting/archive/larsenc2017/). There is a new assessment for ice sheets and an updated permafrost assessment in the Assessments section (http://globalcryospherewatch.org/assessments/).

During 14-21 June 2017, the southern portion of South America was affected by an intense early winter snowstorm that dumped up to 178 cm (70 inches) of snow in mountainous areas of Argentina and Chile and caused record levels of snow extent both in the mountains and in the adjacent plains. http://globalcryospherewatch.org/extremes/

The World Meteorological Organization (WMO) has been granted observer status at the Arctic Council, the leading intergovernmental forum promoting cooperation, coordination and interaction among the Arctic States and communities, particularly on issues of sustainable development and environmental protection in the Arctic. The 10th Arctic Council ministerial meeting, which took place in Fairbanks, Alaska on 12 May, admitted WMO and six other observers. The ministerial declaration recognized the “need to increase cooperation in meteorological, oceanographic and terrestrial observations, research and services, and the need for well-maintained and sustained observation networks and continuous monitoring of the Arctic, such as the World Meteorological Organization’s Global Cryosphere Watch Program.”

A new assessment page has been added that provides an overview of recent changes across the cryosphere. A "stacked" time series plot shows changes in sea ice extent, snow cover, permafrost thaw depth, glacier mass balance, and ice sheet mass change. Look for it in the Assessment section of the Cryosphere Now.
