NAm2k temperature history

Details: Published: Thursday, 15 December 2016 15:24

Members of PAGES' North America 2k (NAm2k) working group analyzed 510 North American borehole temperature–depth profiles to study recent climate changes. The mean North American ground surface temperature history suggests a warming of 1.8 °C between preindustrial times and 2000 AD.

The findings from Fernando Jaume-Santero et al. are discussed in the paper "North American regional climate reconstruction from ground surface temperature histories", which was published yesterday in Climate of the Past.

A regional analysis, composed of mean temperature changes over the last 500 years and geographical maps of ground surface temperatures, show that all regions experienced warming, but this warming is not spatially uniform and is more marked in northern regions.

This is the first published article in the PAGES 2k Network phase 2 synthesis special issue of Climate of the Past.

The due date is 20 December 2016.

Find the proposed session which best suits your abstract here.

You must register for the OSM before submitting an abstract. Register here.

Financial support requests need to be made during the registration process.

PAGES 5th OSM will be held in Zaragoza, Spain, from 9-13 May 2017.

The 3rd Young Scientists Meeting precedes the event (7-9 May) and will be held in Morillo de Tou, north of Zaragoza.

Floods metadata collection

Details: Published: Monday, 12 December 2016 15:17

Can you assist?

PAGES' Floods Working Group (FWG) would like to assemble a worldwide overview of the existing (published) flood records based on historical or natural archives.

This metadata collection will serve:
- to promote all these records to a broad community (through the FWG web site and at the 5th PAGES OSM - Zaragoza, 9-13 May 2017);
- as a first step for the database project of the FWG; and
- as a basis for a review paper on flood reconstructions.

To promote your record(s), please take a few minutes to provide very basic metadata on flood records you produced using this excel file.

Details on the different entries of the excel sheet are described here (pdf).

Examples are also given in the excel spreadsheet.

Once filled in, please email the excel file to This email address is being protected from spambots. You need JavaScript enabled to view it..

Please feel free to transfer this request to any colleagues who might be interested.

Farewell to PAGES' co-chair

Details: Published: Monday, 12 December 2016 11:09

hubertus fischer web Positive answers to two seemingly unrelated questions have led to an outstanding career dedicated to ice-core research for PAGES' outgoing co-chair Hubertus Fischer.

'Do you ski?' and 'Can you cook?' were enough to lure Fischer away from other Master's thesis possibilities. "I could full-heartedly say yes to both."

The questions were posed in 1993 by his eventual University of Heidelberg MSc and PhD supervisor Dietmar Wagenbach, who promptly asked if Fischer was willing to help conduct research in Greenland. He went twice within two years, further fueling his passion for ice-core studies. "These two trips to Greenland in 1993 and 1994 were real expeditions," said Fischer. "We rode over 1000km over the ice on skidoos, drilling shallow cores every 50km. It was not with sled dogs of course, like in the old days, but it was really going 'into the unknown'.

"Deep ice-core drilling projects are more organized, so those two expeditions were my first and most lasting experience, because of the remoteness ... to be in the field, taking care of your science and yourself … the beauty of the ice sheet and the solitude. It was also exhausting!"

Defining the Anthropocene

Details: Published: Thursday, 08 December 2016 09:30

PAGES' visiting guest scientist Erle Ellis is the lead author of a comment piece on defining the Anthropocene, which was published yesterday in Nature.

Ellis et al. argue that the causes of Earth's transition are human and social, therefore scholars from those disciplines must be included in its formalization.

As a tie-in with the paper, Future Earth conducted a Q&A session with Ellis, who further explained why efforts to put a start date on the Anthropocene should not be rushed.
