PAGES - Past Global Changes

ENSO and SAM reconstructions

Details: Published: Monday, 27 April 2020 13:47

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.

Latest PAGES Magazine

Details: Published: Monday, 06 April 2020 12:19

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.

IPCC AR6 review extension

Details: Published: Monday, 06 April 2020 09:13

*New deadlines 29 May and 5 June 2020*

The IPCC has been monitoring the COVID-19 pandemic and related measures undertaken by governments. They support the strong and swift action undertaken worldwide, but note this has serious implications for the timely completion of the IPCC’s Sixth Assessment Report.

IPCC will extend the government and expert review of the Second Order Draft of the Working Group I (WGI) contribution to the Sixth Assessment Report (AR6), originally scheduled to run until 26 April 2020, by six weeks to Friday 5 June 2020.

You must register by 29 May and ensure all review comments are uploaded to the review system by 11:59 CET Friday 5 June 2020.

Extension 12 April for OSM

Details: Published: Thursday, 02 April 2020 08:48

Because of the current disruptions due to coronavirus, the deadline has been extended to 12 April 2020 for session proposals for PAGES' 6th Open Science Meeting (OSM) to take place from 18-22 May 2021 in Agadir, Morocco.

The Scientific Program Committee (SPC) invites you to take an active part in organizing the scientific program of the conference. The OSM program will be comprised of plenary, parallel and poster sessions.

The SPC thanks all those who have submitted a session proposal already. More than 30 sessions have been received, and the extension is for those who were unable to meet the deadline.

The plenary sessions will host keynote talks intended to stimulate discussions on the role of past global change science by providing information about strategies for a sustainable world, on the engagement of stakeholders in active cutting-edge research, and on the added value of interdisciplinary approaches. The parallel and associated poster sessions will accommodate top-level ongoing research.
