Permafrost wordle

This word cloud was generated from data collected in June of this year at the Vulnerability of Permafrost Carbon RCN workshop in Seattle. Workshop participants filled out the permafrost carbon survey estimating the magnitude and timing of permafrost degradation and greenhouse gas release from the permafrost region. Along with quantitative estimates of these fluxes they also filled out a "comments" box for each question where they discussed how they calculated their responses and what assumptions they made. We pooled the comments from all the respondents and generated this visualization using wordle. The size of each word represents how many times it appeared in the comments section (by Ben Abbott & Jennifer Harden).

Nature Comment: Author contribution and acknowledgements:

EAGS and BWA designed the permafrost carbon survey along with FSC III, with additional input from Jeremy B. Jones (UAF). The survey used here was modified from an earlier version developed for the Dangerous Climate Change Project (DanCCAP) lead by Mark New and Jasper Sky as a coordinated effort between Oxford University and the Tyndall Centre for Climate Change Research. EAGS and BWA implemented the survey with experts that attended a three-day workshop in June 2011 in Seattle, WA, USA, as part of the Vulnerability of Permafrost Carbon Research Coordination Network (RCN). In addition, three other experts (FSC, PC, SZ) who were unable to attend the workshop but were previously involved in the survey and/or workshop development process, returned surveys. EAGS wrote text with discussion and feedback from all experts. JH, ADM, KPW, JAO and MW (U.S. Geological Survey) participated in the survey but did not contribute to authorship of the Nature Comment, Nicola Jones provided expert editorial assistance throughout the process.
