Paleo data come from natural sources such as tree rings, ice cores, corals, and ocean and lake sediments - and extend the archive of weather and climate back hundreds to millions of years. The National Oceanic and Atmospheric Administration's (NOAA) Paleoclimatology Program helps the world share scientific data and information related to climate, providing scientists with data and information they ...

This short Why Files article describes how a newer technique, used with radiocarbon dating of sediments from the Bering Strait, allowed scientists to confirm that a land bridge between present-day Alaska and Northeast Asia (Russia) was a probable route taken by human settlers who reached the Americas 12,000 years ago. The previous date was too old by several thousand years, indicating the land bridge ... Full description.

This animation is one result of a determined effort to use new information to better constrain the history of continental dispersal and create a more accurate geological map of reassembled Gondwana. All the continental movements are shown relative to a number of hotspots, the position of which is held fixed with respect to the earth's rotation axis. This gives results that agree overall with paleomagnetic ... Full description.
