Polynesian settled the island about 2000 years ago: highest elevation is about 4. 5 m (~15 ft) above sea level. Has experienced serious flooding in recent years during storms and high tide. Tuvalu may not be able to support its population in 50 to 100 years due to the rise in sea level. 12. 1 global change and earth system science: an overview: earth sciences. 1. understand how earth works and how it has evolved from a landscape of barren rock to the complex landscape dominated by the life we see today. 2. apply that understanding to better manage our environment. Now generally recognized that human activity effects are extensive and not just local or regional.
