As Earth orbit grows more crowded, the risks we face from re-entering space debris are growing alarmingly. A key challenge that we face in understanding the hazards posed by these objects, and their impact on the environment, is that we cannot easily track them once they enter the terminal phase ...
Due to the complexity of the many geophysical processes involved, predictions of future ice sheet mass loss are usually modeled using empirical relations, for example, to determine ice sheet velocities from stresses and meltwater inputs. However, such empirical relations are unlikely to be appropriate for future climate states significantly different ...
