“…This is affected by the atmospheric lifetime of CO 2 emissions through its impact on radiative forcing, which in turn affects thermal expansion of the oceans (Williams et al, 2012) and the risk of melting and/or collapse of the Greenland and West Antarctic ice sheets (Church et al, 2013). In contrast, the proposed Yucca Mountain facility for deep geological disposal of spent fuel and highlevel waste, which is located in the unsaturated zone in fractured rock, is thought to be vulnerable to high-intensity fluvial episodes in a warmer wetter climate through their impact on infiltration (Thorne, 2013). This highlights that, while regional changes in temperature and precipitation are important, modifications to atmospheric and oceanic circulation regimes are also of interest due to their influences on local and regional climates.…”
