Unprecedented warming

Details
Published: Wednesday, 24 July 2019 19:19

WGLogo2kNetworkTwo new PAGES 2k Network papers, published today in Nature and Nature Geoscience, examine temperature trends over the past two millennia and show that recent warming events are unmatched in the past 2,000 years.

The studies, led by Raphael Neukom, find that the rate and spatial consistency of recent warming is extraordinary in the last 2,000 years and cannot be explained by natural factors alone. During the pre-industrial period, volcanic eruptions were the key driver of global temperature fluctuations.

In "No evidence for globally coherent warm and cold periods over the pre-industrial Common Era", published in Nature, authors find that previously named climate epochs of the Common Era were not globally coherent phenomena. This is in contrast to the contemporary anthropogenic warming which we do find is globally coherent to an extent that hasn’t happened in the past 2,000 years.

In "Consistent multidecadal variability in global temperature reconstructions and simulations over the Common Era", published in Nature Geoscience, authors show the most rapid warming of the past 2,000 years occurred during the second half of the 20th century - highlighting the extraordinary character of current climate change, due mostly to human emissions of heat-trapping gases.

Historical climatology paper

Details
Published: Thursday, 11 July 2019 16:18

paleolink cp fig july 19Members of the PAGES 2k Network PALEOLINK project published a new paper yesterday in Climate of the Past which investigates the research potential of historical climatology.

"The weather behind words – new methodologies for integrated hydrometeorological reconstruction through documentary sources" by Salvador Gil-Guirado, Juan José Gómez-Navarro, and Juan Pedro Montávez, presents a new methodology (COST) that allows the performance of climate reconstructions with monthly resolution.

The variability of the climatic series obtained are coherent with previous studies. The new proposed method is objective and is not affected by social changes, which allows the study of regions with different languages and cultures.

Access the paper here.

New ACME working group

Details
Published: Thursday, 11 July 2019 13:51

ACMEPAGES is pleased to announce the launch of the new working group Arctic Cryosphere Change and Coastal Marine Ecosystems (ACME).

The aim of this working group is to assess and refine available marine proxies that can be used to reconstruct past cryosphere changes and their ecosystem impacts. A particular focus will be placed on the techniques and the quality of data, and on the establishment of new protocols to enable more reliable reconstructions, through close dialogue with numerical ecologists and environmental monitoring community.

Climate and cave drip water

Details
Published: Monday, 08 July 2019 17:36

sisal nature comms jul19The world's first global analysis, based on data from 163 drip sites in 39 caves across five continents, has found that stalagmites can assist in tracking past rainfall patterns.

Andy Baker et al.'s recent paper in Nature Communications investigates how climate affects the oxygen isotope composition of cave drip water.

Ideas in this paper were developed thanks to discussions with members of PAGES' SISAL working group. Find out more about SISAL, and sign up to the mailing list, here.

Spanish funding success

Details
Published: Thursday, 27 June 2019 15:35

csic ibcc lo2k fig 19PAGES congratulates 2k Network coordinator Belen Martrat on the recently announced success of her Spanish funding proposal.

Martrat's successful I-LINK proposal, through the national scientific research council (CSIC), is for the IBCC-lo2k project (IBerian Climate Change paleoarchive - synthesis and stewardship of land-ocean data, taking the past 2000 years (2k) as a reference).

The common objective of the project is to synthesize and preserve the climate measurements of the past, integrating land and ocean data of the Iberian region, taking the historical period (last 20 centuries) and beyond as a reference to connect with the instrumental data, in a global context of climate change.
