A novel conceptual model for Dansgaard–Oeschger event dynamics based on ice-core data by J. O. Melcher, S. Halkjær, P. Ditlevsen, P. L. Langen, G. Vettoretti, S. O. Rasmussen

“…Through both analytical and numerical methods, we establish a suitable parameter domain within which the newly adjusted models can accurately replicate the palaeoclimatic records of DO events as described by summary statistics derived from ice-core data. The analysis also shows that, without the novel control parameter, the model does not have a suitable parameter domain in which it can reproduce the wide range of event characteristics seen in the ice-core record. …”

Measurement Report: Changes in ammonia emissions since the 18th century in south-eastern Europe inferred from an Elbrus (Caucasus, Russia) ice-core record by M. Legrand, M. Legrand, M. Vorobyev, D. Bokuchava, S. Kutuzov, S. Kutuzov, A. Plach, A. Stohl, A. Khairedinova, V. Mikhalenko, M. Vinogradova, S. Eckhardt, S. Preunkert

“…Remaining moderate prior to 1950 CE, the increase then accelerated to reach a maximum in 1989 CE. Comparison between ice-core trends and estimated past emissions using state-of-the-art atmospheric transport modelling of submicron-scale aerosols (FLEXPART (FLEXible PARTicle dispersion) model) indicates good agreement with the course of estimated NH<span class="inline-formula">₃</span> emissions from south-eastern Europe since <span class="inline-formula">∼</span> 1750 CE, with the main contributions from south European Russia, Türkiye, Georgia, and Ukraine. …”

Significant greening in the western Tibetan Plateau and surroundings occurred after the 1970s by Renhui Huang, Chunmei Ma, Wangbin Zhang, Xiaoqian Liu, Shuangye Wu, Hongxi Pang, Shugui Hou

“…Abstract Vegetation greening on the Tibetan Plateau (TP) has profoundly changed the connection between terrestrial ecosystems and regional carbon, water, and energy cycling, but existing research on vegetation greenness can only be traced back to the 1980s, because of the scarcity of long-term remote sensing data. Here we present an ice-core record of pollen accumulation rates with a 3-year resolution during 1935–2012 AD for the western TP. …”

High-resolution analyses of concentrations and sizes of refractory black carbon particles deposited in northwestern Greenland over the past 350 years – Part 2: Seasonal and tempora... by K.

Tsushima, A. Tsushima, N. Nagatsuka, N. Nagatsuka, T. Aoki

“…Backward-trajectory analyses suggest that North America was likely the dominant source region of the anthropogenic rBC in the ice core. The increase in anthropogenic rBC shifted the annual concentration peaks of rBC from summer to winter–early spring. …”

Past rapid warmings as a constraint on greenhouse-gas climate feedbacks by Mengmeng Liu, Iain Colin Prentice, Laurie Menviel, Sandy P. Harrison

“…Here we use these events to quantify the centennial-scale feedback strength of CO2, CH4 and N2O by relating global mean temperature changes, simulated by an appropriately forced low-resolution climate model, to the radiative forcing of these greenhouse gases derived from their concentration changes in ice-core records. We derive feedback estimates (95% CI) of 0.155 ± 0.035 W m−2 K−1 for CO2, 0.114 ± 0.013 W m−2 K−1 for CH4 and 0.106 ± 0.026 W m−2 K−1 for N2O. …”

Dated radar-stratigraphy between Dome A and South Pole, East Antarctica: old ice potential and ice sheet history by Rebecca J. Sanderson, Neil Ross, Kate Winter, Robert G. Bingham, S. Louise Callard, Tom A. Jordan, Duncan A. Young

“…Ages of ~38 ± 2.2, ~90 ± 3.6 and ~162 ± 6.7 ka are assigned to the three IRHs, with verification of the upper IRH age from the South Pole ice core. The resultant englacial stratigraphy is used to identify the locations of the oldest ice, specifically in the upper Byrd Glacier catchment and the Gamburtsev Subglacial Mountains. …”

Geothermal heat flux of Ridge B region in Antarctica inferred from basal dry–wet distribution by Shinan Lang, Mingzhu Yang, Xiangbin Cui, Lin Li, Xiaofeng Wang, Jingxue Guo, Jamin S. Greenbaum, Bo Sun, Martin J. Siegert

“…The results show that GHF in Ridge B varies locally and ranges from 48.5 to 65.1 mW m−2, with an average value of 58.0 mW m−2, which is consistent with the current known GHF constrained by subglacial lakes and derived from Vostok ice core temperature measurements. Our work highlights the value of considering local GHF when locating the oldest ice in this potential region or other regions.…”

“…Our findings demonstrate that alkali-rich magmas do not outstrip dacite or rhyolite arc compositions in respect of sulphur abundance and can inform both climate modelling efforts and the search for the eruptions’ signatures in ice core records.…”

Study of the Impact of Past Extreme Solar Events on the Modern Air Traffic by G. Hubert, S. Aubry

“…Abstract The ancient solar energetic particle (SEP) events of 774/775 CE and 993/994 CE were characterized thanks to radionuclide productions stored in environmental archives as ice cores or tree rings. Primary cosmic ray spectra deduced from these cosmogenic isotope data indicate that the impact of these extreme SEP events would have been much more significant than any of the ones observed during the modern era. …”
