An improved mass budget for the Greenland ice sheet
E Enderlin
Geophys. Res. Lett., 41, 2014, doi:10.1002/2013GL059010
http://onlinelibrary.wiley.com/doi/10.1002/2013GL059010/pdf (paywalled, not on ResearchGate)
That paper has already been cited an astonishing 69 times (google-search with title in quotes). In fact Enderlin et al have a follow-up discussion paper now under contentious review which would bring in 2016 thinking. I actually prefer reading the back-and-forth with reviewers to reading a final published version (if there is one here).
The bottom line of these 70 papers? That seems a moving target but can't go on forever without some consensus being reached.
