Eldgjá and Laki: Two large Icelandic fissure eruptions and a historical-critical approach for interdisciplinary researchers working on past nature-induced disasters

open access: yesVolcanica
The integration of archives of societies with archives of nature has led to collaborations between the natural sciences and the humanities. Not all those involved consider these archives equal, which led to some studies featuring explanations promoting ...

Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

open access: yesInternational Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Carbon cycle implications of terrestrial weathering changes since the last glacial maximum

open access: yesFACETS, 2017
We examine the importance of the rock weathering feedback mechanism during the last deglacial period (∼16 000–4000 BCE) using an Earth system model of intermediate complexity (the University of Victoria Earth System Climate Model (UVic ESCM)) with four ...

Characterising City Scale Heat Climatology for Australian Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Three Centuries of ENSO Variability Inferred From Muna, Sulawesi, Indonesia Teak δ18O: Limited Response to Radiative Forcing

open access: yesGeophysical Research Letters
We present an annual resolution oxygen isotope anomaly (Δδ18Oc) record, derived from eight teak (Tectona grandis L.f.) tree ring‐dated δ18Oc series from Muna, Southeast Sulawesi, Indonesia (5.3°S, 123°E).

Co-authorship analysis of the speleothem proxy-climate community: working together to tackle the big problems

open access: yesInternational Journal of Speleology, 2018
Understanding the environmental context of speleothem palaeo-climate proxies is fundamental to their interpretation. We analyse four methodological approaches to accomplish this: stalactite discharge analysis, proxy/process tracer studies, discharge ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

XANES Iron Geochemistry in the Mineral Dust of the Talos Dome Ice Core (Antarctica) and the Southern Hemisphere Potential Source Areas

open access: yesCondensed Matter, 2018
X-ray absorption near edge structure (XANES) measurements at the Fe K-edge were performed on aeolian dust in the TALos Dome Ice CorE drilling project (TALDICE) ice core drilled in the peripheral East Antarctic plateau, as well as on Southern Hemisphere ...
