Understanding the Drivers of Coastal Flood Exposure and Risk From 1860 to 2100
Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Global coastal flood exposure (population and assets) has been growing since the beginning of the industrial age and is likely to continue to grow through 21st century. Three main drivers are responsible: (a) climate‐related mean sea‐level change, (b) vertical land movement contributing to relative sea‐level rise, and (c) socio‐economic ...

Record low Antarctic sea ice coverage indicates a new sea ice state
Communications Earth & Environment, 2023 In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and ...

Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Anthropogenic greenhouse gas emissions are causing unprecedented changes to the climate. In 2015, at the United Nations (UN) Conference of the Parties in Paris, France, countries agreed to limit the global mean temperature (GMT) increase to 2°C above preindustrial levels, and to pursue efforts to limit warming to 1.5°C.

Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls
Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022 Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

Journal of Glaciology, 2021 To improve Antarctic sea-ice simulations and estimations, an ensemble-based Data Assimilation System for the Southern Ocean (DASSO) was developed based on a regional sea ice–ocean coupled model, which assimilates sea-ice thickness (SIT) together with sea-

Deep learning of systematic sea ice model errors from data assimilation increments [PDF]
, 2023 Data assimilation is often viewed as a framework for correcting short-term error growth in dynamical climate model forecasts. When viewed on the time scales of climate however, these short-term corrections, or analysis increments, can closely mirror the systematic bias patterns of the dynamical model. In this study, we use convolutional neural networks

Quaternary sediment patterns in the Weddell Sea: relations and environmental conditions [PDF]
, 1988 Sediment patterns such as texture, composition, and facies from three selected areas of the Antarctic continental margin of the Weddell Sea are discussed in relation to environmental variations of the Quaternary hydrosphere and kryosphere.

The Monterey Event and the Paleocene‐Eocene Thermal Maximum
Geophysical Monograph Series, Page 401-416., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Compilation of Southern Ocean sea-ice records covering the last glacial-interglacial cycle (12–130 ka) [PDF]
Climate of the Past, 2022 Antarctic sea ice forms a critical part of the Southern Ocean and global climate system. The behaviour of Antarctic sea ice throughout the last glacial-interglacial (G-IG) cycle (12 000–130 000 years) allows us to investigate the interactions between sea
