"Paleoclimatology Program's main goal in creating this comprehensive website was to help educate, inform and highlight the importance of paleoclimate research; as well as to show how paleoclimate research relates to global warming and other important issues regarding climate variability and change....We provide the paleoclimatic data and information needed to understand the climate of the past, in order to assess the current and potential future climate in the context of natural climate variability" -- from the website. <http://www.ngdc.noaa.gov/
