The melting of the Greenland ice sheet is speeding up and 2012 already seems to be a record year in terms of this thawing. The potential consequences of this melt on the climate and on the rise of sea levels are such that the island of Greenland and its ice sheet have been the subject of close monitoring by researchers for a number of years. One of them, Xavier Fettweis, a climatology researcher at the University of Liège, has developed a mathematical model which studies different possible scenarios. Whilst this model confirms the acceleration of the thawing, it does not yet take into consideration a factor which has just been revealed in the journal Nature by American researchers working in part on the basis of venturing beyond the model designed by Xavier Fettweis.
