The vast majority of statements in the article can a ascribed to the Sigman & Boyle 2000 paper and the Adkins 2002, but I haven't had time to dig out references for smaller things, such as 120m sea level drop, the changes in glabal salinity and so on; these are featured in the respective texts so they're certain to be accurate. —Preceding unsigned comment added by Oliverjknevitt ( talk • contribs) 20:40, 17 May 2010 (UTC) reply
