Impact attribution is an emerging transdisciplinary sub-discipline of detection and attribution, focused on the social, economic, and ecological impacts of climate change. Here, we provide an overview of common end-to-end frameworks in impact attribution, focusing on examples relating to the human health impacts of climate change. We propose a typology of study designs based on whether [...]

Inverse modeling of satellite observations shows that the wet tropics drive the 2010-2022 methane increase

Zhen Qu, Daniel J. Jacob, Anthony Bloom, et al.

Published: 2024-01-04
Subjects: Atmospheric Sciences, Climate

Atmospheric methane concentrations rose rapidly over the past decade and surged in 2020-2022 but the causes are unclear. We find from inverse analysis of GOSAT satellite observations that global methane emissions increased from 500 to 550 Tg a-1 from 2010 to 2019 and surged to 570-590 Tg a-1 in 2020-2022. Concentrations of tropospheric OH (the main methane sink) show no long-term trend over [...]

The Certainty of Uncertainty in Atmospheric CO2 Removal: A Crisis-Response Abrupt Mitigation Scenario (CRAMS)

Anqi Chen, Bo-Lin Lin

Published: 2023-12-04
Subjects: Climate, Sustainability

The gap between current emission trend and the expected 1.5 °C warming target forces the deployment of different carbon dioxide removal technologies (CDRs). Even though large discrepancies and uncertainties presents in studies investigating the CDR potentials, costs and side effects of bio-energy with carbon capture and storage (BECCS), direct air capture with CO2 storage (DACCS) and enhanced [...]

High-resolution luminescence-dated sediment record for the last two glacial-interglacial cycles from Rodderberg, Germany

Junjie Zhang, Bernd Zolitschka, Ines Hogrefe, et al.

Published: 2023-11-28
Subjects: Climate, Earth Sciences

The Rodderberg Volcanic Complex (RVC) is well-known for the long and probably continuous climate record archived in its crater basin, which lasts for several glacial-interglacial cycles. However, a detailed chronological framework is still lacking. Here, we perform high-resolution luminescence dating on a 72.8 m-long sediment core with the optically stimulated luminescence (OSL) signal from [...]

From Zero to Hero: How to make the Carbon Management Challenge an ambitious lever in the climate fight

Stuart Jenkins, Ingrid Sundvor, Myles Robert Allen

Published: 2023-11-28
Subjects: Climate, Oil, Gas, and Energy

The Carbon Management Challenge (CMC) has set a goal of reaching a minimum of 1 billion tonnes per year of geological carbon dioxide storage by 2030. While in line geological storage required in the International Energy Agency’s Net Zero pathway, there is concern this may be a distraction from the imperative of reducing fossil fuel emissions. Here we show that, if presented in terms of an [...]

Pacific shoreline erosion and accretion patterns controlled by El Niño/Southern Oscillation

Kilian Vos, Mitchell Dean Harley, Ian L Turner, et al.

Published: 2023-10-27
Subjects: Civil and Environmental Engineering, Climate, Earth Sciences, Engineering, Environmental Monitoring, Environmental Sciences, Geomorphology, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics

In the Pacific Basin, the El Niño/Southern Oscillation (ENSO) is the dominant mode of interannual climate variability, driving substantial changes in oceanographic forcing and impacting Pacific coastlines. Yet, how sandy coasts respond to these basin-scale changes has to date been limited to a few long-term beach monitoring sites, predominantly on developed coasts. Here we use 38 years of Landsat [...]

Pygoda: a graphical interface to efficiently visualise and explore large sets of geolocated time series

Yann Ziegler, Jonathan L. Bamber

Published: 2023-10-24
Subjects: Categorical Data Analysis, Climate, Computer Sciences, Databases and Information Systems, Earth Sciences, Environmental Monitoring, Environmental Sciences, Environmental Studies, Fresh Water Studies, Geographic Information Sciences, Geophysics and Seismology, Glaciology, Graphics and Human Computer Interfaces, Hydrology, Longitudinal Data Analysis and Time Series, Meteorology, Other Earth Sciences, Other Statistics and Probability, Spatial Science

Modern-day data sets in geosciences may comprise hundreds or thousands of geolocated time series. Despite all the automated tools and new algorithms now available to process and prepare those data before using them in research projects, it can be useful or even necessary to visualise and investigate them manually. Whether it be for data quality assessment, for the preparation of a training data [...]

Sediment supply controls on Early Eocene delta sequences (South Pyrenean Foreland Basin; Spain)

Romain Vaucher, Claire Musajo, Jorge E. Spangenberg, et al.

Published: 2023-10-13
Subjects: Climate, Geochemistry, Geology, Sedimentology, Stratigraphy

Sediment supply variations are often overlooked when interpreting depositional sequences, which tend to emphasize changes in accommodation. Here, we focus on a temporally well-constrained shallow-marine succession in the South Pyrenean Foreland Basin to test the control of sediment supply on the development of deltaic sequences during the Early Eocene. We analyzed the paleoenvironmental record [...]

Digitization of Weather Records of Seungjeongwon Ilgi: A Historical Weather Dynamics Dataset of the Korean Peninsula in 1623-1910

Kohei Ichikawa, Zeyu Lyu, Yongchao Cheng, et al.

Published: 2023-10-06
Subjects: Climate, Meteorology, Oceanography and Atmospheric Sciences and Meteorology

Historical weather records from Europe indicate that the Earth experienced substantial climate variability, which caused, for instance, the Little Ice Age and the global crisis in the period between the 14th and 19th centuries. However, it is still unclear how global this climate variability was because of the scarce meteorological data availability in other regions including East Asia, [...]

Novel observations of East Asian Summer Monsoon evolution during Glacial Termination II from Lake Suigetsu, Japan

Charlie Rex, Richard Staff, Jaime Toney, et al.

Published: 2023-10-04
Subjects: Climate, Geochemistry

Glacial terminations offer a unique opportunity to examine how the East Asian Summer Monsoon (EASM) responds to rapid increases in global temperature and accompanying abrupt climatic reorganisation. Reconstructions from contrasting glacial terminations with differently evolving boundary conditions are of particular value to our understanding of deglacial EASM behaviours, e.g., Termination I (from [...]

Insights into deglacial East Asian Monsoon seasonality and inter-regional teleconnections from Lake Suigetsu, Japan

Charlie Rex, Richard Staff, Melanie Leng, et al.

Published: 2023-10-04
Subjects: Climate, Geochemistry

The past evolution of the East Asian Monsoon (EAM) was affected by remote climate processes. However, there is uncertainty surrounding these teleconnections and their impact on each seasonal EAM mode during periods of rapid global change. Here we use the unique biannual precipitation patterns of central Japan to reconstruct winter and summer EAM evolution during the last glacial termination [...]

Temporal and Spatial Satellite Data Augmentation for Deep Learning-Based Rainfall Nowcasting

Özlem Baydaroğlu, Ibrahim Demir

Published: 2023-10-03
Subjects: Atmospheric Sciences, Climate, Meteorology, Physical Sciences and Mathematics

Climate change has been associated with alterations in precipitation patterns and increased vulnerability to floods and droughts. The need for improvements in forecasting and monitoring approaches has become imperative due to flash floods and severe flooding. Rainfall prediction is a challenging but critical issue owing to the complexity of atmospheric processes, the spatial and temporal [...]

No respite from permafrost-thaw impacts in absence of a global tipping point

Published: 2023-09-25
Subjects: Biogeochemistry, Climate, Earth Sciences, Geomorphology, Hydrology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics

Arctic permafrost, the largest non-seasonal component of Earth’s cryosphere, contains a significant climate-sensitive carbon pool. Its potential for loss due to climatic changes leading to a global tipping point, where thawing accelerates with disproportionate impacts, remains debated. Here, we provide an integrative perspective on this question, building on a cross-disciplinary meta-analysis of [...]
