Paper questions fluctuation

A new paper from PAGES' PALSEA working group questions the occurrence of a rapid sea-level fluctuation within the Last Interglacial.

Authors, led by the group's next phase co-leader Natasha Barlow, synthesize published geomorphological and stratigraphic indicators from the Last Interglacial, and find no evidence for ice-sheet regrowth within the warm interglacial climate.

They also identify uncertainties in the interpretation of local relative sea-level data that underpin the reconstructions of global mean sea level.

GPWG2 QI special issue

Details

Published: Monday, 30 July 2018 16:32

PAGES' Global Paleofire Working Group 2 (GPWG2) recently released a Special Issue of Quaternary International, titled "The Fire-Human-Climate-Vegetation Nexus".

The group presents nine original manuscripts focusing on paleofire studies that contribute to our understanding of natural and anthropogenic causes of fire through time. It is global in scope, with manuscripts that explore local-to-regional fire histories from five continents: Africa (Kenya), Asia (China), Europe (Romania and Ireland), Southern America (Bolivia) and Northern America (western Canada and the US Rocky Mountains).

PAGES' Scientific Steering Committee (SSC) member Darrell Kaufman has a date with all things data during his six-month sabbatical in Bern, Switzerland.

Normally you will find PAGES' current guest scientist analyzing lake sediment cores from Alaska, as Regents' Professor at the School of Earth and Sustainability, Northern Arizona University, USA. But a data scare and joining the SSC in 2015 have helped shape the current phase of his career.

Abstracts are due 1 August. All details on our calendar here.

Submit an abstract to one of the four PAGES sessions (direct links below):

1. 2k: Climate of the Common Era
2. DAPS: New perspectives on past climates: progress in proxy system modeling, reconstruction algorithms and uncertainty quantification

Warmer Worlds author interview

Published: Monday, 23 July 2018 10:57

The PAGES' Warmer Worlds Integrative Activity paper "Palaeoclimate constraints on the impact of 2°C anthropogenic warming and beyond", published in Nature Geoscience, continues to attract international media attention.

Researchers from 17 countries studied three well-documented historical warm periods - the Holocene thermal maximum, the last interglacial and the mid-Pliocene warm period - to predict future possibilities.

Read the recent Nexus Media article "The Climate Has Always Changed. Why Is This Time so Much Worse?" which contains extended interviews with co-authors Katrin Meissner and Alan C. Mix.
