Global database for temperature reconstructions of the Common Era
Online. — The PAGES2k Phase 2 collection is a community-sourced compilation of temperature-sensitive proxy records associated with the PAGES2k initiative.
The (soon to be published) database gathers 692 records from 648 locations, including all continental regions and major ocean basins.
The records are from trees, ice, sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial.
Nearly half of the proxy time series are significantly correlated with HadCRUT4.2 surface temperature over the period 1850-2014.
Global temperature composites show a remarkable degree of coherence between high- and low-resolution archives, with broadly similar patterns across archive types, terrestrial vs marine locations, and screening criteria.
The database is suited to investigations of global and regional temperature variability over the Common Era.
The Pages 2k compilation is presented on the the LinkedEarth Wiki, online at: http://wiki.linked.earth/Main_Page.
LinkedEarth is an EarthCube-funded project aiming to better organize and share Earth Science data, especially paleoclimate data. LinkedEarth will facilitate the work of scientists by empowering them to curate their own data and to build new tools centered around those. The initial focus in on paleoclimate data, for which they are doing three things: (1) Data Curation, building a platform to crowd source the curation of paleoclimate data, (2) Standards Development, developing standards for how to store & share paleoclimate data, and. (3) Analysis, crafting tools that use these standards to do better science.

Earthcube is a quickly growing community of scientists across all geoscience domains, as well as geoinformatics researchers and data scientists. We are a joint effort between the NSF Directorate for Geosciences and the Division of Advanced Cyberinfrastructure.
