Darrell Kaufman, PAGES SSC member and one of the authors of the recent Scientific Data paper, "A global multiproxy database for temperature reconstructions of the Common Era", talks about the importance of community-endorsed data compilations in an accompanying "behind the scenes" blog post.

Kaufman, professor at Northern Arizona University, USA, describes how there's "more scientific ingenuity to a well-crafted data compilation and more coordination behind a community endorsed data product than meets the eye."

2k leaders explain database

In an accompanying blog post connected to yesterday's Scientific Data paper release, PAGES 2k Network project leaders Julien Emile-Geay and Nicholas McKay explain what's involved in putting together a database of this magnitude.

The Future Earth blog article highlights the difficulties and nuances associated with storing paleodata, which influenced the creation of this open-access database.

Emile-Geay said the new database not only makes the lives of scientists easier, but also provides an invaluable window to Earth’s past which helps us understand how the planet may change in the future.

2k Consortium database paper

Climate scientists will now be able to more accurately study the pattern and causes of global surface temperature changes than was previously possible, thanks to a large international team of scientists contributing to PAGES.

A new paper from PAGES 2k Consortium, titled "A global multiproxy database for temperature reconstructions of the Common Era", published today 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.

Recent VICS contributions

Several recent papers have acknowledged the contribution of PAGES' Volcanic Impacts on Climate and Society (VICS) working group.

Mukund Rao and coauthors explore the European hydroclimate response to volcanic forcing, expanding on work shown at the VICS 2016 meeting in USA. The paper, "European and Mediterranean hydroclimate responses to tropical volcanic forcing over the last millennium", was published in Geophysical Research Letters in May.

Past Global Changes Magazine vol. 25 (1)

The latest issue of Past Global Changes Magazine: Decadal Climate Variability is now available to read and download.

This joint issue with CLIVAR Exchanges aims to review ongoing research on Decadal Climate Variability and Predictability, and address the progress made in understanding and resolving issues on this topic.

It is an output from the CLIVAR-ICTP Workshop on Decadal Climate Variability and Predictability: Challenge and Opportunity held in Trieste, Italy, in 2015.

anchukaitis vics VICS steering group member Kevin Anchukaitis was recently interviewed by Michael White, Nature's editor for climate science, for the podcast "Forecast".

Anchukaitis, an associate professor at The Past Landscapes Lab at the University of Arizona in Tucson, USA, talks about his career and PAGES' Volcanic Impacts on Climate and Society (VICS) working group, which launched in October 2015.

Stocker to give Emiliani Lecture

Details: Published: Wednesday, 05 July 2017 16:16

One of PAGES' former co-directors, Thomas Stocker, will give the Cesare Emiliani Lecture at the AGU Fall Meeting in New Orleans in December 2017.

The Cesare Emiliani Lecture recognizes individuals who have made outstanding scientific contributions to our understanding of paleoclimatology and paleoceanography, and honors the memory of Cesare Emiliani, considered to be the founder of both.

"I am excited to be recognized by the Cesare Emiliani Lecture of the AGU is a great honor, particularly because the award is conferred by the colleagues and peers," said Stocker, who led PAGES from 1999-2004. "Cesare Emiliani, the namegiver of this lecture, reminds us about the many secrets that are still to be revealed by carefully reading the climate archives and combining them with clever model simulations.

"I will most likely talk about the bipolar seesaw, direct paleoceanographic tracer simulations, and modeling challenges from the most recent CO2 reconstructions from an Antarctic ice core."

This is the third year in a row a former PAGES co-chair has been given the honor.
