This three-year, $511,918 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research to develop a new framework for advancing climate model representations of cloud and convective processes. The grantee, Columbia University, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate data assimilation will...
This $169,869 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will support the development of an intermediate complexity Earth system model to simulate the cycling of carbon dioxide and methane between vegetation, soils, the atmosphere, and oceans during the Paleocene-Eocene Thermal Maximum, approximately 56 million years ago. The Regents of the University of California at Riverside will couple representations of the terrestrial and marine carbon cycles...
This three-year, $520,660 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research to constrain cloud and convective parameterizations in climate models using paleoclimate data assimilation. Specifically, the awardee, the University of Arizona, will conduct fully coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and pre-industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate...
The National Science Foundation (NSF), through its Geosciences Program (CFDA 47.050), awarded a $129,436 Project Grant to the University of Illinois to convene an international summit in Fall 2024 to discuss the feasibility of creating a special-purpose computational system for frontier Earth system science and climate projection. The scientific objectives of this project are to bring together international leaders from academia, industry, government, and non-profit organizations to examine...
This National Science Foundation Project Grant of $480,579 will fund research at the University of Washington from August 1, 2022 to July 31, 2025 to reconstruct Earth's energy imbalance over the past 1,000 years. The research will use paleoclimate data assimilation methods to combine proxy climate records with physical constraints from climate models to reconstruct fields like outgoing shortwave and longwave radiation at the top of the atmosphere. This will provide a proxy-constrained...
This $696,515 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research and outreach on variations in the pace of surface temperature change. The awardee, University of California Santa Cruz, will conduct statistical analysis of global climate observations to identify regions and periods with accelerated warming rates over the past two centuries. Model simulations will determine the causes of detected changes and quantify future warming rates...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $312,259 to the University of Alaska Fairbanks (UAF) to conduct collaborative research on the last interglacial period approximately 130,000 to 115,000 years ago, when temperatures were naturally warmer than today. The project aims to better understand when and how much the Greenland and Antarctic ice sheets melted during this period, as well as the climate conditions and ice dynamical...
This $683,266 Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to reconstruct global ice volume and bottom water temperature over the past 1-3 million years. The project at Brown University will analyze multiple climate proxies, including biomarkers and stable isotopes, using machine learning algorithms to resolve global ice volume and ocean temperature signals. The key objectives are to assess the role of CO2 and ice albedo in global...
This $332,944 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at Rowan University from September 2022 through August 2025 to study how the spatial patterns of El Niño Southern Oscillation (ENSO) variability changed during colder background climate conditions approximately 20,000 years ago. The grantee will analyze geochemistry from planktic foraminifera shells collected from sediment cores at key locations in the central and eastern...
This $269,580 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research at Oregon State University to improve paleoclimate reconstruction in high-latitude regions. The university will develop new and enhanced trace element to calcium paleoproxies for understudied temperate to polar planktic foraminiferal species found in the Northern California Current region. Researchers will establish magnesium to calcium-temperature and sodium to calcium-salinity...
