Lost Euro forests: LandCover6k

Details: Published: Tuesday, 16 January 2018 11:36

PAGES LandCover6k working group published a paper yesterday in Nature's Scientific Reports which helps establish the origin of Europe’s current land-cover mosaic via pollen analysis.

Led by Neil Roberts, the authors utilise and compare three numerical approaches to transforming pollen data into past forest cover, drawing on >1000 14C-dated site records. All reconstructions highlight the different histories of the mixed temperate and the northern boreal forests, with the former declining progressively since ~6000 years ago.

Three new 2k projects launch

Details: Published: Monday, 15 January 2018 13:19

The next phase of PAGES' 2k Network continues to grow with the launch of three new projects today. Be involved! Sign up to their mailing lists to stay informed.

ARAMATE focuses on the reconstruction of ecosystem and climate variability in the north Atlantic region using annually resolved archives of marine and terrestrial ecosystems. Read more.

CLIM-ARCH-DATE deals with integration of high resolution climate archives with archaeological and documentary evidence for the precise dating of maritime cultural and climatic events. Read more.

PALEOLINK aims to evaluate and develop new downscaling strategies that allows linking coarse Earth System Model simulations with climate reconstructions. Read more.

New 2k Network projects can be proposed at any time. Do you have a project idea focusing on past global changes of the last 2000 years? Read more here.

New LandCover6k ALCC paper

Details: Published: Thursday, 11 January 2018 18:13

Members of the LandCover6k working group recently published a study on Anthropogenic land-cover change (ALCC) in Land.

Jed Kaplan et al. perform a systematic evaluation of two widely-used ALCC scenarios (KK10 and HYDE3.1) in northern and part of central Europe using an independent, pollen-based reconstruction of Holocene land cover (REVEALS).

Access the article, titled "Constraining the Deforestation History of Europe: Evaluation of Historical Land Use Scenarios with Pollen-Based Land Cover Reconstructions" here.

McGregor's 2k retrospective

Details: Published: Monday, 08 January 2018 11:05

PAGES 2k Network leader Helen McGregor recently published a retrospective article in Nature Geosciences discussing the group's 2013 paper "Continental-scale Temperature Variability During the Past Two Millennia".

Access the retrospective, titled "Regional climate goes global", here.

Cent-Mill climate variability mag

Past Global Changes Magazine vol. 25 (3)

The latest issue of Past Global Changes Magazine, titled "Centennial to Millennial Climate Variability", is now available to read and download.

Guest edited by Michel Crucifix, Anne de Vernal and Christian Franzke, this issue shows how recent progress in our knowledge of past climates led us to revisit our ideas about the spectrum of natural climate variability. Contributions highlight the concept of scaling laws, but also warn about pitfalls of paleoclimate time-series analysis.

This publication is a product of PAGES' Climate Variability Across Scales (CVAS) working group.
