Abstract Regional seas are potentially highly vulnerable to climate change, yet are the most directly societally important regions of the marine environment. In this paper we explore the response of five regional sea areas to potential future climate change, acting via atmospheric, oceanic and terrestrial vectors. Our aim is to elucidate the controlling dynamical processes and how these vary between and within these seas.
Paleo-Indians and Settlement of the Americas This map shows the approximate location of the ice-free corridor and specific Paleoindian sites Clovis theory. It is not definitively known how or when the Native Americans first settled the Americas and the present-day United States.
The prevailing theory proposes that people migrated from Eurasia across Beringiaa land bridge that connected Siberia to present-day Alaska during the Ice Ageand then spread southward throughout the Americas over the subsequent generations.
Genetic evidence suggests at least three waves of migrants arrived from Asia, with the first occurring at least 15 thousand years ago. Pre-Columbian era The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period.
While technically referring to the era before Christopher Columbus ' voyages of toin practice the term usually includes the history of American indigenous cultures until they were conquered or significantly influenced by Europeans, even if this happened decades or even centuries after Columbus' initial landing.
Native American cultures are not normally included in characterizations of advanced stone age cultures as " Neolithic ," which is a category that more often includes only the cultures in Eurasia, Africa, and other regions.
They divided the archaeological record in the Americas into five phases;  see Archaeology of the Americas. According to the oral histories of many of the indigenous peoples of the Americas, they have been living on this continent since their genesis, described by a wide range of traditional creation stories.
Other tribes have stories that recount migrations across long tracts of land and a great river, believed to be the Mississippi River. Archeological and linguistic data has enabled scholars to discover some of the migrations within the Americas.
The Clovis culturea megafauna hunting culture, is primarily identified by the use of fluted spear points. Artifacts from this culture were first excavated in near Clovis, New Mexico.
The culture is identified by the distinctive Clovis pointa flaked flint spear-point with a notched flute, by which it was inserted into a shaft. Dating of Clovis materials has been by association with animal bones and by the use of carbon dating methods.
Recent reexaminations of Clovis materials using improved carbon-dating methods produced results of 11, and 10, radiocarbon years B. Linguists, anthropologists, and archaeologists believe their ancestors comprised a separate migration into North America, later than the first Paleo-Indians.
They constructed large multi-family dwellings in their villages, which were used seasonally. People did not live there year-round, but for the summer to hunt and fish, and to gather food supplies for the winter.
Archaic period in the Americas Since the s, archeologists have explored and dated eleven Middle Archaic sites in present-day Louisiana and Florida at which early cultures built complexes with multiple earthwork mounds ; they were societies of hunter-gatherers rather than the settled agriculturalists believed necessary according to the theory of Neolithic Revolution to sustain such large villages over long periods.
The Formative, Classic and post-Classic stages are sometimes incorporated together as the Post-archaic period, which runs from BCE onward.
The Hopewell tradition was not a single culture or society, but a widely dispersed set of related populations.
They were connected by a common network of trade routes,   This period is considered a developmental stage without any massive changes in a short period, but instead having a continuous development in stone and bone tools, leather working, textile manufacture, tool production, cultivation, and shelter construction.
Their gift-giving feast, potlatchis a highly complex event where people gather in order to commemorate special events. These events include the raising of a Totem pole or the appointment or election of a new chief.
The most famous artistic feature of the culture is the Totem pole, with carvings of animals and other characters to commemorate cultural beliefs, legends, and notable events. A map showing approximate areas of various Mississippian and related cultures. The Mississippian culture was a mound-building Native American civilization archeologists date from approximately CE to CE, varying regionally.
The civilization flourished from the southern shores of the Great Lakes at Western New York and Western Pennsylvania in what is now the Eastern Midwestextending south-southwest into the lower Mississippi Valley and wrapping easterly around the southern foot of the Appalachians barrier range into what is now the Southeastern United States.
The Iroquois League of Nations or "People of the Long House" was a politically advanced, democratic society, which is thought by some historians to have influenced the United States Constitution  with the Senate passing a resolution to this effect in It hangs in the United States Capitol rotunda.
