A rising sea level does not appear to be particularly problematic; the increasing flooding of the subsidiary lagoons would provide easily observed forewarning, and might even benefit seabird populations by making the "motu"s less accessible to predators. In fact, geological data suggests that Kiritimati has withstood prehistoric sea level changes well. The biggest hazard caused by a changing climate would seem to be more prolonged and/or severe droughts, which could even enforce the island's abandonment as they did in 1905. However, it is not clear how weather patterns would change, and it
