2k data assists new paper

PAGES 2k Network data has been used in a new paper on model simulations and proxy-based reconstructions, published yesterday in Nature's Scientific Reports.

The authors, led by Raphael Neukom, assess potential sources of discrepancies between data and models by comparing 1000-year hemispheric temperature reconstructions based on real-world paleoclimate proxies with climate-model-based pseudoproxies.

Access the paper, titled "Possible causes of data model discrepancy in the temperature history of the last Millennium" here.

Two new contributions have been added to the PAGES Early-Career Network (ECN) blog, The Early Pages.

Thomas Ronge investigates the origin of a mysterious, detached buoy and muses about connections and pathways within the Southern Ocean.

And self-confessed introvert Vachel Carter writes how she has harnessed the power of networking at conferences and workshops.

Final PALSEA2 workshop in Eos

Published: Wednesday, 09 May 2018 09:51

Outcomes of the fifth and final meeting of the Paleo Constraints on Sea Level Rise 2 (PALSEA2) working group have been explained in a recent Eos workshop report.

The workshop, held in November 2017 in Playa del Carmen, Mexico, highlighted current research on ice-sheet and sea-level reconstructions, addressed critical gaps in field observations, and assessed the current knowledge of causes, rates, and mechanisms related to sea-level and ice-sheet dynamics during past warm periods.

The new PALSEA leaders have proposed another phase of the working group, and a decision will be made at PAGES SSC Meeting in May.

Technical paper on paleo data

Details

Published: Thursday, 03 May 2018 09:47

The 2k data technical note, which sparked an intense discussion within the paleo community, has been published today as a contribution to the PAGES 2k Network special issue of Climate of the Past.

Lead author Darrell Kaufman and the PAGES 2k special-issue editorial team explain the procedure used to attain a high and consistent level of data stewardship across the special issue. The paper has been chosen as a highlight by journal editor Denis-Didier Rousseau.

Kaufman et al. discuss the challenges related to (1) determining which data are essential for public archival, (2) using data generated by others, and (3) understanding data citations. The team anticipates that open-data sharing in paleosciences will accelerate as the advantages become more evident and as practices that reduce data loss become the accepted convention.

DCV paper in BAMS

Details

Published: Thursday, 26 April 2018 14:58

A succinct review paper about Decadal Climate Variability (DCV) and predictability was recently published in the Bulletin of the American Meteorological Society (BAMS).

Written by Christophe Cassou et al., it is a result from the PAGES-supported "CLIVAR-ICTP Workshop on Decadal Climate Variability and Predictability: Challenge and Opportunity" meeting held in Trieste, Italy, in November 2015.

The study of DCV and predictability is the interdisciplinary endeavor to characterize, understand, attribute, simulate, and predict the slow, multi-year variations of climate at global and regional scales.
