A global multiproxy database for temperature reconstructions of the Common Era

Climate scientists will now be able to more accurately study the pattern and causes of global surface temperature changes than was previously possible, due to a new database for temperature reconstructions of the Common Era.

PAGES 2k global composite, scale to temperature (30y averages)

A new paper from PAGES 2k Consortium, titled «A global multiproxy database for temperature reconstructions of the Common Era», published in Scientific Data, details the findings in version two of their database.

This subgroup of the larger PAGES 2k Network gathered data from 98 regional experts from 22 countries, for a total of 692 records from 648 locations that reflect temperature changes through various biological and physical processes.

The database details the most comprehensive collection of information on global temperature change over the past one to two thousand years and gathers information on past temperature based on evidence from a number of distinct sources including tree-ring measurements, glacier ice, speleothems, corals, sediments from lake and ocean bottoms, and historical documents.
