The past offers a powerful window for understanding future climate change. Evidence from the past, for instance, suggests that ice and melt-water discharge has played a critical role in abrupt climate change. In this general context, the research will target three fundamental objectives. First, to reconstruct and subsequently refine well-constrained deglacial (and eventually full glacial cycle) ice-sheet and melt-water chronologies with well-defined error bars. Second, extending this, to elucidate the role of melt-water fluxes in climate change during the last glacial cycle. Finally, probability distributions for the future evolution of the present-day ice-sheets will be determined and over time refined.

过去为理解未来气候变化提供了一个强有力的窗口。例如，过去的证据表明，冰和融水的排放在气候突变中发挥了关键作用。在这一大背景下，研究将针对三个基本目标。首先，重建并随后完善约束良好的冰消期（最终完整的冰川循环）冰盖和融水年表与定义良好的误差线。第二，扩展这一点，阐明在末次冰期气候变化的融水通量的作用。最后，将确定现今冰盖未来演变的概率分布，并随着时间的推移进行改进。
