Holocene dust special issue

Details

Published: Wednesday, 29 April 2020 14:13

PAGES' former working group Dust Impact on Climate and Environment (DICE) has released the special issue "Holocene Dust Dynamics" in The Holocene.

Guest edited by François De Vleeschouwer, Jan-Berend Stuut, and Fabrice Lambert, the special issue contains nine papers which aim to contribute to a better understanding of the role of dust aerosols.

The articles analyse the evolution and climatic impact of atmospheric dust over long and short timescales within the Holocene in various regions.

It is a partial outcome of discussions held at the group workshop at Las Cruces, Chile, in January 2018.

ENSO and SAM reconstructions

PAGES' 2k Network data have been used in a new Climate of the Past paper by Christoph Dätwyler et al. "Teleconnections and relationship between the El Niño–Southern Oscillation (ENSO) and the Southern Annular Mode (SAM) in reconstructions and models over the past millennium".

The climate of the Southern Hemisphere (SH) is strongly influenced by ENSO and SAM variations. Because of the limited length of instrumental records in most parts of the SH, very little is known about the relationship between these two key modes of variability over time.

Using proxy-based reconstructions and last-millennium climate model simulations, authors find that ENSO and SAM indices are mostly negatively correlated over the past millennium. Pseudo-proxy experiments indicate that currently available proxy records are able to reliably capture ENSO–SAM relationships back to at least 1600 CE.

Paleoclimate-records database

Details

Published: Thursday, 16 April 2020 09:14

In the new Scientific Data paper "A global database of Holocene paleotemperature records" by Darrell Kaufman et al., authors present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene.

This database helps place recent warming into the longer-term context of natural climate variability.

Data were compiled from 679 sites where time series cover at least 4000 years and derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives.

The database contains 1319 records, including 157 from the Southern Hemisphere.

PAGES provided additional support for workshops leading up to this data product.

Call for new ECN SC members

Details

Published: Thursday, 09 April 2020 08:23

The PAGES Early-Career Network Steering Committee (ECN SC) seeks new members and the call has been extended until Thursday 16 April 2020.

The primary tasks of the ECN SC include coordination and broad visioning of the ECN. The committee meets every two weeks to organize ongoing and future activities; manage communications and updates among clusters, members, and the larger PAGES and ECN communities; and ensure the ECN goals are being broadly supported.

Proven experience (either academic or non-academic) in paleosciences and/or Earth sciences is highly desirable.

Past Global Changes Magazine vol. 28 (1)

The new Past Global Changes Magazine, titled "Past Plant Diversity and Conservation" is now available to read and download.

Guest edited by Rachid Cheddadi, Selene Báez, Signe Normand, Davnah Payne, and Pierre Taberlet, this issue aims to highlight possible contributions of paleodata to conservation initiatives, as these data contain a wealth of information about past climate changes in terms of trends, abruptness, and velocity, and on plants' diversity down to their infraspecific level.
